Movable Engaging Member With Restricting Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engaging members with movable engaging portions struggle to withstand large loads without excessive deformation or damage, particularly when subjected to unexpected loads during assembly or operation.
Innovation Solution
The engaging member incorporates a linking portion and a movement restricting portion to allow for relative movement in the longitudinal and insertion directions while preventing excessive deformation, using a pantograph-like shape and through portions to restrict movement within a predetermined range, thereby distributing loads and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the engaging portion is made movable to absorb positional displacement, then the ease of assembly is improved, but the strength and reliability deteriorate when large loads are applied
Solution Approach 1:
The engaging portion is designed to be movable relative to the attachment portion through the linking portion, allowing dynamic adjustment to absorb positional displacement between the engaging portion and the fixing hole. This dynamic capability improves ease of assembly while the movement is controlled within safe limits to prevent excessive loading.
Solution Approach 2:
The movement restricting portion is provided beforehand to prevent excessive movement of the engaging portion. By restricting the movement range in advance, the linking portion is protected from experiencing loads beyond its design capacity, preventing damage before it occurs.
2Adaptability or versatility
If the engaging portion is made movable to absorb positional displacement, then the adaptability is improved, but the reliability deteriorates under unexpected large loads
Solution Approach 1:
The movable engaging portion provides adaptability to accommodate positional displacement and misalignment during assembly. The linking portion enables this adaptive movement while the movement restricting portion ensures that the adaptability does not compromise reliability by limiting the movement to safe ranges.
Solution Approach 2:
The movement restricting portion acts as a preventive measure that is built into the structure beforehand. It protects the linking portion from unexpected large loads by restricting excessive movement, ensuring reliable operation even when unusual load conditions occur during assembly or service.
3Ease of operation
If the movement range is increased to improve assembly flexibility, then the ease of operation is improved, but the risk of excessive deformation increases
Solution Approach 1:
The linking portion provides dynamic movement capability that improves assembly flexibility, allowing the engaging portion to adjust its position. The movement restricting portion simultaneously maintains structural stability by defining clear boundaries that prevent excessive deformation of the linking portion.
Solution Approach 2:
The movement restricting portion is designed beforehand to prevent excessive deformation. By establishing movement boundaries in advance, it protects the linking portion from deformation beyond acceptable limits while still allowing sufficient movement range for flexible assembly operations.

AI summary
An engaging member includes an engaging portion configured to be inserted and assembled into a fixing hole of a vehicle body, an attachment portion configured to attach elongated wire routing materials, and linking portions configured to connect the engaging portion and the attachment portion to each other. The linking portions are extendable and contractable in a longitudinal direction of the wire routing materials, and can oscillate the engaging portion side in an orthogonal direction, thereby allowing the engaging portion to be movable in the longitudinal direction and the orthogonal direction. A protrusion and a through portion are provided as a movement restricting portion for restricting the movement of the engaging portion to movement within a predetermined range.
