Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED lighting with photovoltaic cells is designed as an independently functioning light fitting, then solar energy rechargeability is achieved, but compatibility with conventional light fixtures is lost
Solution Approach 1:
The LED lighting system is divided into two separate functional parts: a battery-powered LED module that can be inserted into conventional fixtures, and a separate photovoltaic charging module. This segmentation allows the LED module to be compatible with existing fixtures while the photovoltaic module provides solar recharging capability independently.
Solution Approach 2:
The LED lighting module is designed with a universal base that can be inserted into conventional light fixtures, making it compatible with existing infrastructure. Simultaneously, it incorporates photovoltaic charging capability, enabling it to function both as a replaceable bulb and as a solar-powered device.
2Use of energy by moving object
If independently functioning LED fittings with photovoltaic cells are introduced, then solar-powered functionality is achieved, but replacement costs increase due to costly light fixture replacements
Solution Approach 1:
The photovoltaic charging function is extracted as a separate module from the LED lighting function. The LED module with battery can be inserted into existing fixtures without replacement, while the photovoltaic module is separately attached to provide charging, thereby avoiding costly fixture replacements.
Solution Approach 2:
A removable battery module serves as an intermediary between conventional light fixtures and solar-powered LED lighting. This intermediary component allows the fixture to remain in place while enabling solar-powered operation through the battery-photovoltaic system.
3Adaptability or versatility
If LED lighting is designed to be independent from mains power, then energy independence is achieved, but integration with existing lighting control systems is lost
Solution Approach 1:
The LED lighting module incorporates its own battery power source and control circuitry, making it self-sufficient and independent from mains power. It can be controlled independently through its own switch or remote control, without requiring integration with existing mains-powered control systems.
