DESIGN THINKING & ITS IMORTANCEDesign Thinking is a method used by designers to solve complex

problems, and find desirable solutions for clients. When design principles

are applied to strategy and innovation the success rate for innovation dra-

matically improves. Design thinking is at the core of effective strategy de-

velopment and organizational change. Design can be applied to products,

services, processes, physical locations, etc. anything that needs to be op-

timized for human interaction. You can design the way you lead, manage,

create and innovate.


INTRODUCTION

In photovoltaic systems, trackers help minimize the angle of inci-dence (the angle that a ray of light makes with a line perpendicular to the surface) between the incoming light and the panel, which increases the amount of energy the installation produces. Concentrated solar photo-voltaic and concentrated solar thermal have optics that directly accept sun-light, so trackers must be angled correctly to collect energy. All concen-trated solar systems have trackers because the systems do not produce en-ergy unless directed correctly toward the sun.

Single-axis trackers rotate on one axis moving back and forth in a single direction. Different types of single-axis trackers include horizontal, vertical, tilted, and polar aligned, which rotate as the names imply. Dual-axis trackers continually face the sun because they can move in two differ-ent directions. Types include tip-tilt and azimuth-altitude. Dual-axis track-ing is typically used to orient a mirror and redirect sunlight along a fixed axis towards a stationary receiver. Because these trackers follow the sun vertically and horizontally they help obtain maximum solar energy genera-tion.

There are also several methods of driving solar trackers. Passive trackers move from a compressed gas fluid driven to one side or the other. Motors and gear trains direct active trackers by means of a controller that responds to the sun’s direction. Finally, a chronological tracker counteracts the Earth’s rotation by turning in the opposite direction.

Selecting a solar tracker depends on system size, electric rates, land constraints, government incentives, latitude and weather. Utility-scale and large projects usually use horizontal single-axis trackers, while dual-axis trackers are mostly used in smaller residential applications and locations with high government Feed-In-Tariffs. Vertical-axis trackers are suitable for high latitudes because of their fixed or adjustable angles.

REVERSE ENGINEERING

What is Reverse Engineering?

Reverse engineering is also called back engineering is the processes of extracting knowledge or design information from anything man-made and reproducing any new thing based on extracted information .The pro-cess often involves disassembling something like electronic component, computer program, any type of hardware and analyzing its components and works in detail. Reverse engineering is generally used when a person or business organization cannot recollect how something was done so re-versely analysis is done.

Why Reverse Engineering?

The aim of reverse engineering is to draw out many kinds of inform-ation from existing software and using this information for system renova-tion and program understanding. Based on traditional practice, reverse en-gineering and requirements engineering are two separate processes in soft-ware round trip engineering.

In this paper, we argue that it is necessary to recover requirements

from the reverse engineered outcome of legacy system and by integrating

this outcome in the requirements phase of software life cycle, it is possible

to have a better requirements elicitation, and clear understanding of what

is redundant, what must be retained and what can be re-used.


Advantages:-

Trackers generate more electricity than their stationary counterparts due to increased direct exposure to solar rays. This increase can be as much as 10 to 25% depending on the geographic location of the track-ing system.

There are many different kinds of solar trackers, such as single-axis and dual-axis trackers, all of which can be the perfect fit for a unique jobsite. Installation size, local weather, degree of latitude and electrical requirements are all important considerations that can influ-ence the type of solar tracker best suited for a specific solar installa-tion.

Solar trackers generate more electricity in roughly the same amount of space needed for fixed tilt systems, making them ideal for optimizing land usage.

In certain states some utilities offer Time of Use (TOU) rate plans for solar power, which means the utility will purchase the power gener-ated during the peak time of the day at a higher rate. In this case, it is beneficial to generate a greater amount of electricity during these peak times of day. Using a tracking system helps maximize the energy gains during these peak time periods.

Advancements in technology and reliability in electronics and me-chanics have drastically reduced long-term maintenance concerns for tracking systems.


Disadvantages:-

Solar trackers are slightly more expensive than their stationary coun-terparts, due to the more complex technology and moving parts nec-essary for their operation. This is usually around a $0.08 – $0.10/W increase depending on the size and location of the project.

Even with the advancements in reliability there is generally more maintenance required than a traditional fixed rack, though the quality of the solar tracker can play a role in how much and how often this maintenance is needed.

Trackers are a more complex system than fixed racking. This means that typically more site preparation is needed, including additional trenching for wiring and some additional grading.

Single-axis tracker projects also require an additional focus on com-pany stability and bankability. When it comes to getting projects fi-nanced, these systems are more complex and thus are seen as a higher risk from a financier’s viewpoint.

Fixed racking systems offer more field adjustability than single-axis tracking systems. Fixed systems can generally accommodate up to 20% slopes in the E/W direction while tracking systems typically of-fer less of a slope accommodation usually around 10% in the N/S di-rection.


SCAMPER TECHNIQUE

The SCAMPER idea generation technique is founded on the belief that

everything new is an alteration of something already in existence. The

term ‘SCAMPER’ is actually an acronym.

The full form of the individual letters is given below:

S – Substitute C – Combine A – Adapt M – Modify P – Put to another use


https://www.cleverism.com/18-best-idea-generation-techniques/

E – Eliminate R – Reverse

Substitute:-

Take away a part of the selected thing, concept or situation and re-

place it with something else. Anything can be an item for substitution. The

possibilities include steps in a process, product parts, the people or the

place. Substitution is a technique of trial and error, of replacing one object

with another till you are able to determine the correct idea.

Some questions:

What resources or materials can you swap or substitute to enhance the product?

What process or product could you utilize? Can you utilize other materials or ingredients? Can you change its colour, sound, smell or roughness? Can you modify its shape? Which rules can you substitute or change? Is it possible to replace someone involved? Can you utilize the idea in another place? What would happen if you modified your attitude or feelings towards

the product?


https://www.cleverism.com/color-theory-how-you-can-apply-it-for-branding/

Combine:-

The next step is to contemplate combining elements of the situation or problem you’re facing so as think up something new. This is in line with the view of many creativity experts that creativity has to do with combining already existing things in a fresh way.

So join, force together or affiliate two or more elements pertaining to your subject matter and contemplate routes by which such a combination could possibly take you to a solution.

Some questions:

What parts, ideas or materials could be possibly combined?

What could they be combined with to optimize uses?

What could be the result of combining the product in question with

another, to develop something new?

What could be the result of combining objectives or purposes?

How to combine resources and talent to develop a new way of think-

ing directed at the product?

Can different elements be combined to enhance it?

Adapt:-

Think if there’s a solution for another problem that you may mold to

suit your situation.


https://www.cleverism.com/creativity-boost-how-to-think-out-of-the-box/

Some questions:

Is there a solution you can take from somewhere else and mold it to

suit this one?

Is there a similarity between the current situation and something

else?

Is there another context you can position your product in?

What or who could you imitates to adapt this product to fulfill an-

other use or purpose?

What else does the product resemble?

What other ideas or products can you utilize for inspiration?

Are there any ideas outside your field that you can incorporate?

Modify:-

Pose a question to yourself about which ideas you can produce if

you magnify or modify your situation or problem. Magnifying parts of or

the whole of your idea may enhance its perceived worth or furnish fresh

insight pertaining to which components are most significant.

Some questions:

Can you change an aspect of your process or product to enhance it?

Can you think of any ways to modify the shape, feel, appearance,

color or form of your product?

What can you add to change this product?

What can you highlight or emphasize to produce more value?


What aspect of the product can you make stronger to develop some-

thing new?

What would happen if you modified the process in some way?

Put to another use:-

Contemplate how you can put your current idea to different uses or

what could be reused from elsewhere so as to fix your own problem. Fre-

quently, an idea only turns out to be great when applied in a different man-

ner than first imagined. Modify the goal of the subject. Contemplate why it

exists, its purpose of use and what it is assumed to do. Confront all of

these suppositions and propose new and strange purposes.

Some questions:

Is it possible to utilize this product elsewhere, maybe in another in-

dustry?

Who else can utilize this product?

Would this product function differently in a different setting?

Is it possible to recycle the product’s waste to create something new?

What else could it is utilized for?

How could a child or older person utilize it?


Eliminate:-

Contemplate what would happen if you eliminated components or

elements of your idea or if you minimized, reduced or simplified aspects

of it. By way of repeated elimination or trimming of ideas, processes and

objects, it is possible to steadily constrict your challenge to that function or

part of the most significance.

Some questions:

How can you simplify or streamline this product?

What can you tone down or understate?

What components can be taken out without changing function?

What would be the outcome should you take away a component of

the product? What would replace the component/part?

Reverse:-

Contemplate what you would do if a portion of your process/

product/probortunity was done or worked in another order, or in reverse.

Reverse the orientation or direction. Turn it inside-out, upside-down, or

backwards – just make it go against the direction it was meant to be used

or to proceed.


http://www.ianharvey.com.au/images/adminimages/gallery/gallerydocument/17s_Probortunity.pdf

Some questions:

Can you interchange components?

Can you transpose cause and effect?

Can you transpose negatives and positives?

Can you interchange the patterns or layout?

What is the best way to interchange the patterns or layout?

What other sequence, layout or patterns can you use? Can you think

of any?

Can you modify the schedule of delivery or pace?

How can you reorganize this product?

Can you modify the order of steps in your process?

What other arrangement may be better?

What would be the outcome of process reversal?

What if you turned it upside down?

How can you reverse roles?

Can you rearrange or reverse the concept you already have?

What if you engaged in the exact opposite of what you originally in-

tended?

How could you accomplish the opposite effect?


INTRODUCTION OF CANVAS

This report is all about mind mapping, AEIOU summary, empathy

mapping, ideation canvas, and product development canvas. Team mem-

bers have chosen the topic is solar tracking system. We had visited the dif-

ferent areas and observed the atmosphere and the environment of our

topic; we all have Visited different areas of solar power plant and take

some pictures from it. Design Engineering is the subject which gives us

better knowledge about our efficiency to observe. We have love to study

the design engineering subject, it’s all about great joy and pleasure to cre-

ative our brain power and used the observation power and created mind

map, and some other important sheets by our observation.

energy resources. In this paper is described the design and construc-tion of a microcontroller based solar panel tracking system. Solar tracking allows more energy to be produce because the solar array is able to remain aligned to the sun. The paper begins with presenting background theory in light sensors and stepper motors as they apply to the project. In the conclusions are given discussions of design res-ults.

2. Programmable logic controller based design and imple-

mentation of multiple axes solar tracking system

Author:- Omar Talal Mahmood


Published in:- Electrical, Communication, Computer, Power, and

Control Engineering (ICECCPCE), 2013 International Conference

Publisher:- IEEE

Abstract:-

The power generation using solar energy has been used widely many years ago due to fuel shortage and its low cost. In this paper, a design and implement of dual axis solar tracking system has been implemented using programmable logic controller (PLC). This pro-posed system, keeps the solar panels aligned with the sun during the sunrise hours, in order to maximize solar power extracted from the sun. In this work an open loop control systems been designed and carried out using PLC, and direct current motors for solar cell sun tracking. The tracking has done in two manners, that is, the usual daily sun tracking vertically, and the seasonal sun tracking ho-rizontally. The second tracking technique, computes the difference in the day hours per year in four seasons, with the aid of PLC pro-gram, which is the solar time of the day hours or the sunrise hours of the day. After the system has completely installed a suitable meas-urement has been carried out for the fixed and moving solar panel. As compared with usual fixed panels, the power that has been ob-tained from the solar system is 38% better than the fixed technique.

SUMMARY OF REVERSE ENGINEERING

The term "reverse engineering" includes any activity you do to determ-ine how a product works, or to learn the ideas and technology that were originally used to develop the product. Reverse engineering is a systematic approach for analyzing the design of existing devices or systems. You can


use it either to study the design process, or as an initial step in the redesign process, in order to do any of the following:

Observe and assess the mechanisms that make the device work Dissect and study the inner workings of a mechanical device Compare the actual device to your observations and suggest im-

provements

Before you decide to re-engineer a component, be sure to make every effort to obtain existing technical data. For example, you can proceed with reverse engineering if replacement parts are required and the associated technical data is either lost, destroyed, non-existent, proprietary, or incom-plete.

Reverse engineering may also be necessary if alternative methods of obtaining technical data are more costly than the actual reverse engineer-ing process. Generally, many products are protected by copyrights and pat-ents. Patents are the stronger protection against copying since they protect the ideas behind the functioning of a new product, whereas a copyright protects only its look and shape. Often a patent is no more than a warning sign to a competitor to discourage competition. If there is merit in an idea, a competitor will do one of the following:

Negotiate a license to use the idea Claim that the idea is not novel and is an obvious step for anyone ex-

perienced in the particular field Make a subtle change and claim that the changed product is not pro-

tected by the patent.
