Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional probing methods are used on contact surfaces, then the probing process is simple, but surface oxides, oils, and debris prevent good electrical connections
Solution Approach 1:
The patent changes the physical and chemical parameters of the contact surface by applying conductive elastomers with specific properties (conductive, compliant, self-healing) to transform the probing interface from a rigid, contamination-sensitive contact to a resilient, contamination-resistant connection that maintains reliable electrical contact despite surface contaminants
Solution Approach 2:
The patent uses composite materials by combining conductive fillers (such as metal particles or carbon) within an elastomeric matrix to create conductive elastomers that possess both electrical conductivity and mechanical compliance, enabling them to penetrate and maintain contact through surface contaminants while providing stable electrical connections
2Reliability
If conductive elastomer is applied to penetrate surface contaminants, then electrical connection quality improves, but device complexity increases
Solution Approach 1:
The patent employs flexible thin films in the form of conductive elastomer layers that are applied to the probing surface or contact elements. These flexible films conform to surface irregularities and maintain continuous electrical contact despite surface contaminants, providing improved reliability without requiring complex mechanical structures
Solution Approach 2:
The conductive elastomer acts as an intermediary material between the probing element and the contact surface. This intermediary layer penetrates and bridges through surface contaminants (oxides, oils, debris) to establish direct electrical contact with the underlying conductive surface, thereby improving connection quality while keeping the overall device structure relatively simple
