Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple LED devices are directly welded on the module through pads, then the luminous brightness is greatly improved, but the heat accumulation inside the module increases significantly
Solution Approach 1:
The pad structure is segmented by introducing openings that divide the pad into multiple regions, creating heat dissipation channels that allow heat to escape from the interior of the pad, thereby reducing heat accumulation while maintaining the luminous brightness improvement
Solution Approach 2:
Metal material is introduced as an intermediary substance filled into the openings of the pads to enhance heat conduction and dissipation efficiency, serving as a thermal pathway between the heat-generating LED devices and the external environment
2Duration of action of moving object
If the service time of LEDs is prolonged, then the display duration is extended, but the temperature of the device becomes too high, reducing service life and display effect
Solution Approach 1:
Heat dissipation openings are pre-designed and pre-positioned in the pad structure before LED operation begins, establishing heat dissipation pathways in advance to prevent excessive temperature buildup during prolonged operation, thereby extending service life while maintaining display effect
Solution Approach 2:
The heat generated by prolonged LED operation, which is normally a harmful factor, is converted into a manageable parameter by introducing metal-filled openings that facilitate controlled heat dissipation, transforming the heat accumulation problem into an effective thermal management solution
