Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used to transmit signals between sheet-like communication devices, then signal transmission reliability is improved, but device complexity and ease of operation deteriorate due to connection requirements
Solution Approach 1:
The patent replaces mechanical wired connections with electromagnetic field-based wireless communication. The sheet-like communication device uses electromagnetic waves to transmit signals to external devices, eliminating the need for physical connectors and cables. This substitution maintains signal transmission reliability while dramatically improving ease of operation and user-friendliness.
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary medium for signal transmission. Instead of direct wired connections, the electromagnetic field acts as a mediator to carry signals between the sheet-like communication device and external devices, enabling wireless communication while maintaining reliable signal transmission.
2Reliability
If wired connections are used for signal transmission, then signal stability is improved, but maintenance complexity increases
Solution Approach 1:
The patent replaces mechanical wired connections with electromagnetic field-based wireless communication. By eliminating physical connectors, cables, and wiring infrastructure, the system removes the primary sources of maintenance issues such as connection failures, wire degradation, and connector wear. This substitution maintains signal stability while dramatically improving maintenance efficiency.
3Productivity
If electrodes are positioned close to the sheet-like conductor for efficient signal carrying, then signal transmission efficiency is improved, but device complexity increases due to positioning requirements
Solution Approach 1:
The patent transitions from two-dimensional planar electrode arrangements to three-dimensional spatial positioning of electrodes relative to the sheet-like conductor. By utilizing the third dimension (distance from the sheet surface), the system achieves efficient electromagnetic coupling without requiring complex in-plane electrode configurations, thus improving signal transmission efficiency while maintaining relatively simple device structure.
Solution Approach 2:
The patent optimizes signal transmission efficiency by adjusting key parameters including electrode distance from the sheet-like conductor, electrode area, and operating frequency. By systematically varying these parameters, the system achieves optimal electromagnetic coupling efficiency without requiring complex electrode structures, thereby improving productivity while controlling device complexity.
