Wiring Member Snap Attachment for Secure Locking and Easy Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiring attachment methods, such as those described in Patent Document 1, face difficulties in detaching wiring members from attaching target members due to elastic deformation issues, making it hard to remove the wiring member during repairs.
Innovation Solution
The proposed solution involves an attachment structure with convex-shaped and concave-shaped parts, where an elastic deformation part allows the convex-shaped part to fit into the concave-shaped part when inserted and release when pulled, facilitating easy detachment by elastic deformation in both directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first locking part is elastically deformed in a spreading direction when force is applied to lock the clamp to the attaching hole, then the clamp is securely locked and cannot be pulled out, but this makes it difficult to detach the wiring member during repair
Solution Approach 1:
The locking part is designed with elastic deformation capability that allows it to dynamically change shape during both locking and detaching operations. The same elastic deformation part that provides secure locking when compressed also enables easy detachment when expanded in the opposite direction, making the system adaptable to both states without requiring different structural components.
Solution Approach 2:
The elastic deformation part changes its physical state between compressed and expanded configurations. When compressed, it provides strong locking force; when expanded in the opposite direction, it releases the locking state. This parameter change in the same component resolves the contradiction between secure locking and easy detachment.
2Strength
If the elastic deformation part is designed to provide strong locking force in one direction, then the attachment is secure, but the wiring member becomes difficult to remove
Solution Approach 1:
The detaching operation uses the opposite elastic deformation direction compared to the locking operation. While locking compresses the elastic deformation part in one direction to engage the locking part, detaching expands it in the opposite direction to disengage, effectively using reverse action to achieve the opposite function.
Solution Approach 2:
The elastic deformation part serves dual functions by being dynamically configurable: compressed for strong locking and expanded for easy release. This dynamic adaptability allows the same component to provide both strong attachment and easy detachment without compromising either function.

Function Achieved in This Case
This design enables easy detachment of the wiring member from the attaching target member, allowing for efficient removal and reattachment using male and female snap fasteners, ensuring secure and removable attachment.
Implementation Method 1
an elastic deformation part is formed in at least one of the convex-shaped part and the concave-shaped part, and when the convex-shaped part is inserted into the concave-shaped part upon receiving force toward a first direction, the elastic deformation part is elastically deformed by the force toward the first direction to fit the convex-shaped part to the concave-shaped part

AI summary
In an attachment structure of a wiring member, the wiring member and an attaching target member are attached using a convex-shaped part, a concave-shaped part, and an elastic deformation part. When the convex-shaped part is inserted into the concave-shaped part upon receiving force toward a first direction, the elastic deformation part is elastically deformed by the force toward the first direction to fit the convex-shaped part to the concave-shaped part. When the convex-shaped part is pulled from the concave-shaped part upon receiving force toward a second direction opposite to the first direction, the elastic deformation part is elastically deformed by the force toward the second direction in a direction similar to the case of receiving the force toward the first direction, and releases the fitting state of the convex-shaped part and the concave-shaped part.
