Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional reading lamps use only visible light LEDs for illumination, then the lighting function is simple and reliable, but the lamp lacks versatility and cannot perform data transmission
Solution Approach 1:
The reading lamp integrates multiple functions into a single device: visible light LEDs provide illumination while IR LEDs enable data transmission. The modulation unit allows the same LED structure to serve dual purposes by modulating IR emission for communication protocols, transforming a single-function lighting device into a multi-functional system that combines lighting and data communication capabilities
Solution Approach 2:
The patent combines separate functional components (visible light LEDs, IR LEDs, modulation unit, optical unit) into an integrated reading lamp system. The control unit merges lighting control and data transmission control into a unified system, allowing coordinated operation of illumination and communication functions through a single device interface
2Adaptability or versatility
If the reading lamp adds IR LEDs and modulation unit for data transmission, then versatility is improved, but device complexity increases
Solution Approach 1:
The reading lamp integrates multiple functions into a single device: visible light LEDs provide illumination while IR LEDs enable data transmission. The modulation unit allows the same LED structure to serve dual purposes by modulating IR emission for communication protocols, transforming a single-function lighting device into a multi-functional system that combines lighting and data communication capabilities
Solution Approach 2:
The patent combines separate functional components (visible light LEDs, IR LEDs, modulation unit, optical unit) into an integrated reading lamp system. The control unit merges lighting control and data transmission control into a unified system, allowing coordinated operation of illumination and communication functions through a single device interface
3Illumination intensity
If the optical unit focuses light emission, then illumination intensity is improved, but the light distribution becomes more concentrated and may affect surrounding areas
Solution Approach 1:
The optical unit creates a localized concentrated light beam with specific directional properties, focusing illumination precisely on the user's reading material while minimizing light scattering into surrounding areas. This local quality enhancement ensures high illumination intensity at the target area without creating harmful light disturbance for neighbors or surrounding environments
