Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corrugated tube protection members require manual engagement of coupling concave and convex parts, degrading mounting workability when attaching to a wire harness.
Innovation Solution
A corrugated tube protection member with a cylindrical body part formed by a pair of divided members connected by a hinge and a leaf spring, allowing for easy opening and closing to simplify the mounting process without the need for manual engagement of lock structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a lock structure with coupling concave and convex parts is used to connect divided members, then the structural integrity is improved, but the mounting workability deteriorates due to manual engagement requirements
Solution Approach 1:
The protection member utilizes the elastic deformation of the wire harness itself to automatically engage the coupling convex parts with coupling concave parts. The wire harness acts as its own mounting tool, eliminating the need for manual engagement operations while maintaining secure connection
Solution Approach 2:
The divided members are pre-configured with coupling convex and concave parts in specific positions and orientations. This preliminary arrangement ensures that when the protection member is placed over the wire harness, the coupling elements are already positioned to engage automatically as the members close, preventing the need for manual alignment
2Strength
If divided members are connected with a lock structure, then the connection strength is improved, but the device complexity increases
Solution Approach 1:
The protection member is divided into multiple members with coupling convex and concave parts distributed along the circumference. This segmentation allows the structure to achieve strong connection through multiple distributed engagement points rather than a single complex locking mechanism
Solution Approach 2:
The coupling convex and concave parts are integrated directly into the divided members themselves, eliminating the need for separate lock structures or fastening components. The structural elements serve dual purposes: maintaining cylindrical shape and providing self-locking connection
