Integrated Wire Harness Clamp With Elastic Fixing Pieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness clamps require multiple components and complex assembly processes, increasing production costs and reducing efficiency due to the need for separate body and engaging portions.
Innovation Solution
A clamp design featuring a base plate, shaft, and fixing pieces with an interval wider than the attaching hole's maximum opening width, allowing elastic deformation and secure attachment to an adhesive sheet without additional components, along with a pressing portion for enhanced stability and water-tight sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the clamp is divided into multiple components (body and engaging portion), then the reliability of attachment is improved, but the device complexity and production cost increase
Solution Approach 1:
The patent combines the body and engaging portion into a single integrated clamp structure. The engaging portion is formed as an integral part of the body, eliminating the need for separate components and assembly steps while maintaining the functional reliability of the attachment system.
2Reliability
If the clamp is divided into multiple components, then the reliability of attachment is improved, but the productivity decreases due to additional assembly steps
Solution Approach 1:
The integration of the engaging portion with the body eliminates the assembly step of connecting separate components. The clamp can be installed as a single piece, significantly improving assembly efficiency and productivity while maintaining attachment reliability through the integrated design.
3Ease of manufacture
If the interval between fixing pieces is larger than the maximum opening width of the attaching hole, then the ease of manufacture is improved, but the stability of the object's composition worsens
Solution Approach 1:
The fixing pieces are designed to be elastically deformable, allowing them to flex during installation when the interval exceeds the hole width. After insertion, the elastic recovery of the fixing pieces provides continuous pressing force that secures the adhesive sheet fringe, maintaining stability while enabling easier manufacture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy attachment and secure fixing of the clamp to the adhesive sheet, reducing component count and assembly complexity while maintaining stability against vibrations and providing water-tight sealing.
Implementation Method 1
the fringe of the attaching hole which contacts the fixing pieces that have the interval between the projecting ends which is wider than the maximum opening width of the attaching hole is elastically deformed and stretched

AI summary
A clamp includes a base plate that is locked to an adhesive sheet which covers and holds an electric wire, a shaft that projects from the base plate and is inserted through an attaching hole which is bored through the adhesive sheet, an engaging portion that is formed at the distal end of the shaft, is inserted through the attaching hole and is engaged with an engaging hole of an attached body, and fixing pieces that project from the base plate to have an interval between projecting ends of the fixing pieces which is larger than the maximum opening width of the attaching hole, and hold and fix the fringe of the attaching hole with the base plate.
