Wire Holding Structure for Stable and Retrofittable Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wire harness fixing structures lack stability in the positional relationship between flat circuit bodies and wire harnesses, preventing the attachment of additional wires.
Innovation Solution
A wiring member comprising a holding member with specific wire holding portions that can stabilize the positional relationship between power and communication lines, allowing for retrofittable attachment of wires, including parallel wires, while enabling the wires to be bent and securely positioned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a binding member is used to bind the flat circuit body and wire harness together, then the assembly is secured, but the positional relationship between the flat circuit body and wire harness becomes unstable
Solution Approach 1:
The holding member is divided into multiple wire holding portions (first, second, and third wire holding portions) that can independently hold different wires at fixed positions. This segmentation allows each portion to stabilize the position of specific wires while maintaining overall structural integrity, resolving the contradiction between stability and complexity.
Solution Approach 2:
The holding member acts as an intermediary component between the flat circuit body and wire harness, providing fixed wire holding portions that stabilize the positional relationship without requiring complex binding structures. The holding member mediates the connection by offering dedicated slots for power lines and communication lines.
2Reliability
If the wire harness fixing structure is designed to stabilize positional relationships, then position stability is improved, but the ability to attach additional wires afterwards is lost
Solution Approach 1:
The holding member incorporates both fixed wire holding portions for initial wires and a retrofittable third wire holding portion that can be added later. This dynamic design allows the structure to adapt from a basic two-wire configuration to a three-wire configuration as needed, maintaining positional stability while enabling future wire attachment.
Solution Approach 2:
The holding member is designed with pre-formed first and second wire holding portions that can immediately hold power and communication lines, while also incorporating a retrofittable third wire holding portion that prepares the structure for future wire attachment without requiring redesign or additional complex components.
3Reliability
If multiple wires are held at fixed positions, then positional relationship is stabilized, but the wiring configuration becomes rigid and cannot be modified
Solution Approach 1:
The holding member combines fixed wire holding portions that provide stable positioning with a retrofittable third wire holding portion that enables configuration changes. This dynamic design allows the wiring to be initially configured with two wires for stable operation, while maintaining the capability to add a third wire when operational requirements change.

AI summary
A wiring member includes a plurality of wires and a holding member for holding the plurality of wires. The plurality of wires include a power line and a communication line that extend in the same direction. The holding member includes a plurality of wire holding portions that each can hold a wire at a fixed position. The power line is held by a first wire holding portion of the plurality of wire holding portions. The communication line is held by a second wire holding portion of the plurality of wire holding portions. At least one of the plurality of wire holding portions is formed to be capable of retrofittably holding the wire.
