Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple LED chips and electric components are arranged on a circuit substrate, then the display functionality is achieved, but the module size increases and compactness is reduced
Solution Approach 1:
The patent combines multiple LED chips (red, green, blue) and electric components onto a single circuit substrate, integrating display functionality into one compact module. This merging approach achieves full-color display capability while maintaining a small form factor suitable for mobile device applications.
Solution Approach 2:
The circuit substrate serves multiple functions simultaneously: it provides mechanical support for LED chips, electrical connections through conductive channels and pads, and houses additional electric components for enhanced functionality. This multi-functionality reduces the need for separate components and contributes to compact design.
2Manufacturing precision
If LED chips are densely arranged to improve display resolution, then information display capability is enhanced, but heat dissipation becomes more difficult
Solution Approach 1:
The patent implements localized heat management by providing individual heat dissipation paths for each LED chip through the circuit substrate structure. The substrate design includes specific thermal conduction channels that direct heat away from each light-emitting group, allowing high-density arrangement while maintaining effective heat dissipation at each local location.
3Reliability
If a translucent encapsulating component is added to protect LED chips, then reliability is improved, but the structure becomes more complex
Solution Approach 1:
The encapsulating component serves multiple functions simultaneously: it protects the LED chips from environmental damage, provides structural support for the entire light-emitting module, and facilitates heat dissipation through its thermally conductive material. This multi-functionality reduces the need for separate protective structures, simplifying the overall design while maintaining high reliability.
