Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional illumination systems (sodium vapor lamps, mercury vapor lamps, incandescent bulbs, fluorescent tubes) are used for large area illumination, then sufficient illumination intensity is achieved, but energy consumption is high
Solution Approach 1:
The illumination system is segmented into multiple individual LED light sources arranged in a two-dimensional array on a carrier device. Each LED is a separate, controllable unit that contributes to the overall illumination, allowing efficient energy distribution across large areas while maintaining sufficient illumination intensity through the collective output of many discrete light sources
Solution Approach 2:
The system transitions from conventional lamp technologies to LED technology, fundamentally changing the light generation parameter from thermal radiation and gas discharge to electroluminescence. This parameter change enables dramatically reduced energy consumption while maintaining or improving illumination intensity, as LEDs convert electrical energy to light more efficiently than conventional sources
2Illumination intensity
If complex structures with separate lenses and filler materials are used in illumination systems, then optical performance is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The system merges the functions of multiple separate optical components into a single integrated LED array structure. Instead of using separate lenses, reflectors, and filler materials to control and distribute light, the LEDs themselves are arranged in a two-dimensional pattern that inherently provides the desired illumination distribution, eliminating the need for additional optical components and simplifying the overall device structure
Solution Approach 2:
The LED array structure serves multiple functions simultaneously: it provides light generation, optical distribution, and structural support all in one configuration. The two-dimensional arrangement of LEDs on the carrier device creates a universal platform that can illuminate large areas without requiring application-specific optical components, reducing device complexity while maintaining optical performance
