Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two distinct connecting elements are used to enable current flow for diagnosis, then the diagnosis circuit can test antenna positioning and connection, but the device complexity increases and radiofrequency performance may be affected by complex return paths
Solution Approach 1:
The patent combines the functions of two separate connecting elements into a single conductive element made of conductive elastomer. This single element simultaneously provides the current injection path and the return path for the diagnosis circuit, eliminating the need for two distinct connecting elements and their associated complex return path configuration.
Solution Approach 2:
The conductive element serves multiple functions: it acts as both the current injection connector and the return path connector for the diagnosis circuit. Additionally, it maintains electrical connection between the antenna and the circuit board while providing a simple, unified structure that reduces overall device complexity.
2Reliability
If a complex return path is used for diagnosis current, then the diagnosis circuit can function, but radiofrequency performance is degraded due to interference
Solution Approach 1:
The patent extracts and eliminates the complex return path that causes radiofrequency interference. By using a single conductive element that inherently provides both current injection and return paths in a simplified configuration, the harmful return path is removed while maintaining diagnosis circuit functionality.
Solution Approach 2:
The conductive elastomer element acts as an intermediary that provides a controlled, simplified path for diagnosis current while preventing it from creating harmful radiofrequency interference. Its material properties and configuration mediate between the diagnosis circuit requirements and the radiofrequency performance requirements.
