Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If infrared signals are used for remote control, then directional control is achieved, but flexibility is reduced
Solution Approach 1:
The patent replaces infrared signal transmission with radio frequency signals for remote control. This substitution eliminates the directional limitation of infrared signals while maintaining wireless control capability, thereby improving remote control flexibility without requiring line-of-sight alignment between the remote control and the lighting device.
2Ease of operation
If radio frequency signals are used for remote control, then flexibility is improved, but device size increases
Solution Approach 1:
The patent integrates the radio frequency receiver, controller, and light emission sources into a single unified lighting device structure. By merging these components, the patent achieves omnidirectional remote control capability without significantly increasing the overall device volume, as the radio frequency components are incorporated within the existing lighting device housing.
3Ease of operation
If conventional remote control is used, then short-distance control is achieved, but control range is limited
Solution Approach 1:
The patent replaces conventional infrared remote control with radio frequency-based remote control. Radio frequency signals have longer transmission range and better penetration capability compared to infrared signals, enabling remote control over relatively large distances and expanding the control range for network or large-size situations.
4Illumination intensity
If multiple light emission sources are integrated, then light output is enhanced, but thermal management becomes difficult
Solution Approach 1:
The patent divides the light emission sources into multiple separate light emitting diodes distributed across the lighting device. Each LED is individually mounted with its own thermal management path, allowing heat to be dissipated through multiple separate channels rather than concentrating thermal load in a single location, thereby managing thermal effects while maintaining high light output.
