Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual tracking and inspection of electrical wire connections is performed by designers, then connection validity can be verified, but the process becomes labor-intensive and time-consuming
Solution Approach 1:
The patent replaces the manual mechanical inspection process with an automated computer-based system. The continuity inspection device automatically compares auxiliary device-based wiring information with region-based connector/wiring information to verify electrical wire connections, eliminating the need for designers to manually track and inspect connections, thus reducing inspection time while maintaining verification reliability
Solution Approach 2:
The inspection system performs self-verification by automatically comparing wiring information data structures and determining connection validity without requiring external manual intervention. The device independently identifies discrepancies and validates connections, making the verification process autonomous and efficient
2Reliability
If manual inspection methods are used, then connection errors can be detected, but the process is prone to human errors
Solution Approach 1:
The patent replaces human manual inspection with an automated computer-based comparison system that eliminates human error. The continuity inspection device systematically compares wiring information data structures and determines connection validity with consistent, repeatable accuracy, removing the variability and potential for human mistakes inherent in manual inspection processes
Solution Approach 2:
The inspection system provides automated feedback by comparing auxiliary device-based wiring information with region-based connector/wiring information and identifying discrepancies. This systematic feedback mechanism ensures that all connection errors are detected and reported consistently, improving both error detection capability and inspection accuracy
3Productivity
If automated computer-based inspection is implemented, then inspection efficiency is improved, but system complexity increases
Solution Approach 1:
The continuity inspection device serves multiple functions: it compares auxiliary device-based wiring information with region-based connector/wiring information, identifies electrical wire connections, determines connection validity, and generates inspection reports. By consolidating these multiple inspection functions into a single automated system, the patent improves overall inspection efficiency while managing system complexity through functional integration
Solution Approach 2:
The inspection system creates and compares digital copies of wiring information from different sources (auxiliary device-based wiring information and region-based connector/wiring information). This approach allows automated verification without requiring physical wire tracing, significantly improving inspection efficiency while keeping the system complexity manageable through information-based rather than physical-based inspection

AI summary
Disclosed is a wire harness continuity inspection method for inspecting for the presence of errors in connections of electrical wires described in region-based connector/wiring information using an electronic computer. The wire harness continuity inspection method according to the invention includes: a referring step (S201) of referring to auxiliary device-based wiring information to specify a first terminal of a first electrical component and a second terminal of a second electrical component connected by a circuit line, which are described in the auxiliary device-based wiring information; a first specifying step (S202) of referring to region-based connector/wiring information to specify a first electrical wire of which one end is connected to the first terminal of the first electrical component, described in the region-based connector/wiring information; and a first determining step (S203) of determining whether the terminal connected to the other end of the first electrical wire is identical to the second terminal of the second electrical component.
