Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If advanced functionalities like immersive video capture and display are added, then video capture capability is improved, but device complexity increases
Solution Approach 1:
The imaging system is divided into multiple independent lens assemblies (first lens assembly, second lens assembly, third lens assembly, fourth lens assembly) positioned at different orientations around the device. Each lens assembly captures video from a specific direction, and the processor integrates these segmented views into a complete 360-degree immersive video. This segmentation allows advanced video capture functionality while managing device complexity through modular architecture.
2Productivity
If multiple high-performance components are added for immersive video, then video processing capability is improved, but heat generation increases
Solution Approach 1:
The patent extracts and separates heat-generating components (processor and graphic processing units) from the main device body by coupling them to dedicated heat dissipation structures. The processor is coupled to a first heat dissipation structure, and graphic processing units are coupled to a second heat dissipation structure. This extraction isolates heat sources, allowing high-performance video processing while managing thermal output through dedicated pathways.
Solution Approach 2:
Heat dissipation structures serve as intermediary elements between the high-performance processing components and the device environment. These intermediaries (heat dissipation structures) facilitate thermal management by providing dedicated pathways for heat transfer, enabling the processor and graphic processing units to operate at high performance levels without excessive heat affecting the overall device temperature.
3Reliability
If security features like fingerprint sensors are added, then data security is improved, but ease of use deteriorates
Solution Approach 1:
The fingerprint sensor is merged with the existing touchscreen display structure, allowing security authentication to be integrated into the natural user interaction flow. Users can authenticate by placing their finger on the display surface during normal operation, combining security verification with the existing ease of use of touchscreen interaction rather than adding separate authentication hardware that would complicate operation.
