Introduction
Value engineering (VE) is a systematic method to improve the "value" of goods or products and services by using an examination of function. Value, as defined, is the ratio of function to cost.
It is a primary tenet of value engineering that basic functions be preserved and not be reduced as a consequence of pursuing value improvements.

Design 1- INTEGRATED BATTERY within BULBHOLDER
Adding Function of an integrated battery, that gets charged with heat/light energy produced by the bulb, when connected via electricity. If the electricity goes off, the battery gets activated and the bulb is switched ON .
Though the cost of the bulb holder increases, the function of the bulb holder increases many times. Houses that have power cuts up to 8 hours may consider replacing for this design.
Material used for the new design will be better, better technology

Design 2- MINIMALIZED material
Value can be increased if we reduce the material of Brass and spring used in the bulb holder. This can be achieved if re-design the plate inside the holder, closer to the bulb. Also the bulb is interlocked by threading. The number of threads can be controlled and reduced.
This design will use lesser material and better interlocking techniques.

Design 3- SAFE DESIGN
The most important aspect of a bulb holder is that it should be safe for uses to use.In our third option, we use superior quality material and complex design using magnetic
plates, that will ensure easy & safe usage for wiring and attaching the bulb.
Superior Material, durable product & ease of use
