Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antenna electrode combinations are changed according to rotation angles to maintain signal transmission on a rotatable display screen, then image signal transmission reliability is improved, but circuit complexity and cost increase due to additional detection and switching circuits
Solution Approach 1:
The antenna system is segmented into multiple antenna electrodes arranged in specific patterns (e.g., alternating polarity arrangements) on both transmission and reception boards. This segmentation allows the system to maintain signal transmission through geometric arrangement rather than complex circuit switching, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The invention employs a rotatable reception board that dynamically changes its orientation relative to the transmission board. The antenna electrodes are arranged in rotationally symmetric patterns, allowing the system to maintain signal transmission across different rotation angles without requiring dynamic circuit reconfiguration, thus maintaining reliability while avoiding increased complexity.
2Adaptability or versatility
If rotation angle detection circuits and signal array switching circuits are added to support rotatable display screens, then adaptability to different rotation angles is improved, but manufacturing cost increases due to additional high-speed selector circuits
Solution Approach 1:
The antenna electrodes are arranged in asymmetric patterns (such as alternating polarity arrangements) that create rotationally symmetric signal transmission characteristics. This allows the system to adapt to different rotation angles through geometric design rather than expensive switching circuits, resolving the contradiction between adaptability and manufacturing cost.
Solution Approach 2:
The invention replaces expensive high-speed selector circuits and rotation detection circuits with simple, fixed antenna electrode arrangements. The adaptability is achieved through the geometric configuration of inexpensive antenna electrodes rather than through costly active circuit components, significantly reducing manufacturing cost while maintaining versatility.
3Adaptability or versatility
If multiple integrated circuits are connected in multiple stages to create high-speed selector circuits for signal array switching, then signal transmission adaptability is improved, but circuit size increases significantly
Solution Approach 1:
The invention extracts the signal transmission adaptability function from complex multi-stage IC selector circuits and implements it through the geometric arrangement of antenna electrodes. By taking out the switching function and replacing it with fixed geometric patterns, the circuit size is dramatically reduced while maintaining signal array adaptability across different rotation angles.
Solution Approach 2:
The invention replaces the mechanical/electronic switching system (multiple ICs connected in stages) with a static geometric arrangement of antenna electrodes. The adaptability that previously required active switching circuits is now achieved through the spatial configuration of antenna elements, eliminating the need for large multi-stage IC assemblies and significantly reducing circuit size.
