Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of light emitted diodes are used to produce various color temperatures and colors, then the adaptability and versatility of the light apparatus is improved, but the device complexity increases due to multiple substrates and control circuits
Solution Approach 1:
The patent combines multiple types of light emitted diodes (first, second, third, fourth, and fifth LEDs) onto a single elongated substrate, merging multiple light sources into one integrated structure. This reduces the number of separate components while maintaining the capability to produce various color temperatures and colors through controlled activation of different LED types.
Solution Approach 2:
The elongated substrate serves as a universal platform that can accommodate and activate different types of light emitted diodes based on lighting requirements. The single substrate structure can produce white light with different color temperatures, colored light, or combinations thereof, making it a multi-functional device that replaces what would traditionally require multiple separate lighting components.
2Adaptability or versatility
If multiple light emitted diodes are activated and mixed to achieve desired light parameters, then the adaptability is improved, but the control complexity increases
Solution Approach 1:
The control circuit dynamically adjusts the activation and mixing of different light emitted diodes based on desired lighting outcomes. By controlling which LEDs are active and at what intensity levels, the system can adapt to produce various color temperatures and colors on demand, with the control circuit managing the complexity of coordinating multiple light sources.
3Use of energy by moving object
If traditional incandescent bulbs are replaced with LED technology, then the energy efficiency is improved, but the ability to produce various color temperatures and colors becomes more complex
Solution Approach 1:
The patent segments the light generation function into multiple specialized light emitted diodes, each optimized for specific wavelength ranges (blue, red, green, etc.). This segmentation allows each LED type to operate at high efficiency in its optimal range while the control system combines them to achieve various color temperatures and colors, maintaining energy efficiency while enabling color versatility.
