Wire Harness Continuity Inspection Pattern Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for creating region-based connector/wiring information for wire harness continuity inspection are time-consuming and have a trade-off relationship with accuracy, as the number of patterns increases, requiring a balance between time and accuracy in the success/failure determination step.
Innovation Solution
A wire harness continuity inspection method that references specification codes for each partitioned area, specifies the most relevant areas, and creates region-based connector/wiring information for combinations of wire harnesses in those areas, optimizing the number of patterns to be created and inspected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of region-based connector/wiring information patterns is increased to improve inspection accuracy, then the accuracy of success/failure determination is improved, but the time required for the determination step increases
Solution Approach 1:
The patent segments the wire harness inspection process by dividing region-based connector/wiring information into multiple patterns. Instead of inspecting all possible patterns simultaneously, the system divides them into a first plurality of patterns and a second plurality of patterns, enabling systematic and efficient inspection while maintaining comprehensive coverage for accuracy.
Solution Approach 2:
The patent applies preliminary action by determining the plurality of patterns in advance before conducting the success/failure determination. The system determines the first plurality of region-based connector/wiring information patterns and the second plurality of patterns beforehand, which allows for optimized inspection procedures and reduces the time required during the actual determination step.
2Reliability
If all possible combinations of wire harnesses across all partitioned areas are inspected, then comprehensive inspection coverage is achieved, but the complexity and time consumption of the inspection process increases
Solution Approach 1:
The patent segments the comprehensive inspection task by dividing region-based connector/wiring information into multiple distinguishable patterns. This segmentation allows the system to maintain comprehensive inspection coverage while organizing the complex data into manageable groups that can be processed systematically.
Solution Approach 2:
The patent changes the parameter of pattern organization by determining multiple distinct patterns of region-based connector/wiring information. By establishing different pattern categories (first plurality and second plurality), the system transforms a complex monolithic inspection task into structured, parameterized groups that are easier to manage and inspect comprehensively.

AI summary
The time required for a success or failure determination step and the precision of the success or failure determination step are optimized by determining region-based connector or wiring information and by adjusting increase and decrease of the number of such patterns. Region-based connector or wiring information is created for at least every described region in numbers equal to the number of combinations of a first wire harness, a second wire harness, and a third wire harness. The first wire harness is one of first wire harnesses arrangeable in Main 1, the second wire harness is one of second wire harnesses arrangeable in Main 2, and the third wire harness is one of third wire harnesses arrangeable in Sub, and presence or absence of error in connection of electric wires is inspected in the created region-based connector or wiring information.
