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 that electronically retrieves wiring information and automatically validates connections, eliminating the need for designers to manually track wires through diagrams
Solution Approach 2:
The system creates and processes electronic copies of wiring information from design drawings and service manuals, allowing automated validation without requiring physical manual inspection of original diagrams
2Reliability
If manual wire harness validation is performed, then connection errors can be detected, but the complexity of the inspection process increases
Solution Approach 1:
The system performs self-validation by automatically retrieving its own wiring information data and checking connections without requiring external manual intervention, thereby simplifying the overall process while maintaining detection capability
3Reliability
If designers manually inspect wire connections, then validation can be performed, but the burden on designers increases
Solution Approach 1:
The patent substitutes the designer's manual inspection labor with an automated computer system that performs all validation tasks electronically, significantly reducing the designer's workload while maintaining complete validation coverage

AI summary
Disclosed is to inspect 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 regarding step of referring to region-based connector/wiring information to specify a first certain electrical wire and a second certain electrical wire of which one end is connected to the other end of the first certain electrical wire which are described in the first region-based connector/wiring information, and regarding the first certain electrical wire and the second certain electrical wire as a single electrical wire; a referring step of referring to auxiliary device-based wiring information to obtain 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 of referring to the 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 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.
