Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intermediate elements are used to electrically connect wire elements, then antenna loop formation is achieved, but device complexity and manufacturing complexity increase
Solution Approach 1:
The patent removes the intermediate element from the system by using a loopback circuit on the second chip to electrically connect the two wire elements. This extraction eliminates the need for separate intermediate connecting elements, thereby reducing device complexity and manufacturing steps while maintaining the antenna loop formation functionality.
Solution Approach 2:
The second chip is designed with multi-functionality: it serves both as a signal processing chip and as a connection point for forming the antenna loop through its loopback circuit. This universal design eliminates the need for dedicated intermediate connecting elements, reducing both device complexity and manufacturing requirements.
2Manufacturing precision
If multiple cutting tools are used to cut conductive wires and form conductive segments, then antenna configuration is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent extracts the need for multiple cutting operations by designing the system so that wire elements are inserted into grooves rather than being cut and assembled. The loopback circuit on the second chip provides the electrical connection without requiring intermediate conductive segments to be precisely positioned and connected through multiple cutting steps.
Solution Approach 2:
The wire elements are prepared in advance as continuous conductors that are simply inserted into the grooves of the chips. The groove structures are pre-formed to receive the wire elements, eliminating the need for on-site cutting and assembly operations. This preliminary preparation simplifies the manufacturing process while maintaining precise antenna configuration.
