Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of components is increased to meet varied consumer demand, then the functionality and versatility of the digital camera is improved, but the heat generated by internal elements increases making the device harder to cool
Solution Approach 1:
The patent divides the internal structure into multiple separate frames (first frame, second frame, third frame) positioned between different heat-generating components. Each frame acts as an independent thermal management unit, segmenting the heat dissipation pathways to prevent heat accumulation in any single location while maintaining the necessary component density for versatile functionality.
2Length of moving object
If the digital camera is made smaller and thinner, then the portability is improved, but the heat dissipation capability deteriorates
Solution Approach 1:
The patent introduces multiple frames arranged in the depth dimension (front-to-back orientation) rather than relying solely on lateral spacing. The first frame is positioned between the imaging unit and first display unit, the second frame between the first heat generator and second heat generator, and the third frame between the second heat generator and second display unit. This three-dimensional arrangement enables effective heat dissipation paths within a compact thickness.
3Adaptability or versatility
If multiple display devices are installed to enhance functionality, then the adaptability is improved, but the heat discharge capability deteriorates
Solution Approach 1:
The patent positions frames as intermediary thermal management structures between the heat-generating display devices and the rest of the camera body. The first frame acts as an intermediary between the imaging unit and first display unit, while the second and third frames serve as intermediaries between the heat generators and second display unit. These intermediary frames create dedicated thermal pathways that allow heat from multiple display devices to be discharged efficiently without compromising the additional display functionality.
