Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification of electrical joint connections is performed, then joint quality can be confirmed, but technician time and labor are significantly consumed
Solution Approach 1:
The electrical joint monitoring device enables the joint itself to provide verification information automatically. The conductive members and fasteners form an integrated monitoring system that self-identifies connection quality through electrical property measurements, eliminating the need for manual verification by technicians.
Solution Approach 2:
The patent replaces manual mechanical verification with automated electrical measurements. Conductive contacts and measurement circuits substitute for technician hands and tools, using electrical property changes to detect joint quality without physical inspection.
2Reliability
If numerous electrical joints are inspected manually, then all joints can be verified, but the inspection process becomes extremely time-consuming
Solution Approach 1:
Each electrical joint is equipped with an integrated monitoring device that automatically performs verification functions. The joints self-monitor their own connection quality through built-in conductive contacts and measurement circuits, enabling simultaneous inspection of multiple joints without sequential manual checks.
Solution Approach 2:
The monitoring devices are pre-installed on electrical joints during assembly, so verification capability is already in place before operation begins. This preliminary placement of measurement circuits and conductive contacts eliminates the need for later manual inspection setup.
3Reliability
If difficult-to-reach electrical joints are accessed for verification, then complete monitoring is achieved, but technician effort and time increase significantly
Solution Approach 1:
The monitoring device is integrated directly into the electrical joint structure, with conductive contacts and measurement circuits built into the fasteners and conductive members. This integration allows the joint to self-monitor without requiring external access or technician intervention, even for difficult-to-reach locations.
Solution Approach 2:
The monitoring function is merged with the structural components of the electrical joint itself. Conductive contacts are combined with fasteners, and measurement circuits are integrated into the joint assembly, eliminating the need for separate external monitoring equipment that would require physical access.
