Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If different part numbers are prepared for different connection target positions, then connection accuracy is improved, but device complexity increases
Solution Approach 1:
The sheet is divided into multiple regions by split lines, allowing different connection configurations to be segmented into distinct areas. This enables a single part number to accommodate multiple connection target positions through selective use of different sheet regions, thereby improving connection accuracy without increasing device complexity.
Solution Approach 2:
The sheet structure is designed with multiple split lines and regions that can accommodate different connection configurations. A single wiring member design can serve multiple part numbers by utilizing different combinations of connectors and transmission members within the same sheet, achieving multi-functionality and reducing the need for separate part numbers for different connection positions.
2Adaptability or versatility
If multiple wire harness configurations are prepared for different connection targets, then adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The wiring member incorporates foldable portions that allow dynamic reconfiguration of the sheet and transmission members. This enables a single manufactured part to adapt to different connection targets by folding and arranging components in various configurations, improving adaptability while maintaining manufacturing simplicity through standardized production processes.
Solution Approach 2:
Split lines are pre-formed in the sheet during manufacturing, creating predetermined separation lines that facilitate later configuration adjustments. This preliminary action enables easy adaptation to different part numbers through simple cutting and folding operations without requiring complex manufacturing processes for each variant.
3Device complexity
If a single wiring member design is used for multiple part numbers, then device complexity is reduced, but connection precision may worsen
Solution Approach 1:
Different regions of the sheet are designed with specific local characteristics, including positioned transmission members and connectors optimized for particular connection targets. By selecting and activating appropriate local regions through foldable portions and split lines, the design maintains connection precision for each specific application while using a unified overall structure.
Solution Approach 2:
The sheet is segmented into multiple functional regions by split lines, with each region optimized for specific connection configurations. This segmentation allows the single design to maintain high connection precision for each part number by isolating and optimizing local connection areas while keeping the overall device complexity low through standardized sheet and transmission member designs.

AI summary
A wiring member includes a first connector, a second connector, a first wire-like transmission member connected to the first connector, a second wire-like transmission member connected to the second connector, and a sheet to which the first wire-like transmission member and the second wire-like transmission member are fixed. The first and second wire-like transmission members extend on the sheet in parallel to each other so that an end portion of the first wire-like transmission member connected to the first connector and an end portion of the second wire-like transmission member connected to the second connector are directed to a first end portion of the sheet. A split line for splitting the sheet is formed in the sheet, the split line extends between the first wire-like transmission member and the second wire-like transmission member, and one end portion of the split line reaches an edge of the first end portion.
