Wire Harness Binding Structure for Height Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wire harness binding structures fail to effectively reduce the height of wire harnesses with a round cross-section over a wide range in the longitudinal direction without excessive material waste and displacement.
Innovation Solution
A binding structure that includes a clamp with a plate-shaped placement portion and pressing portions that press-expand the wire harness laterally to reduce its height, combined with a binding member that maintains this state, while minimizing material usage and preventing displacement through strategically positioned extending portions and a flexible joining mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the portion for gripping the wire harness is elongated in the longitudinal direction, then the wire harness can be held in a reduced height state over a wider range, but material usage increases wastefully
Solution Approach 1:
The clamp is divided into multiple functional portions: a placement portion for supporting the wire harness, a pressing portion with pressing body portions for applying pressure, and opposing extending portions for structural support. This segmentation allows the grip function to be distributed across multiple compact elements rather than requiring a single long elongated portion, achieving wide grip range without excessive material usage.
Solution Approach 2:
The wire harness is pressed to transition from a round cross-section to a flattened state with reduced height in the height direction, while expanding in the lateral width direction. This dimensional transformation allows the wire harness to maintain a reduced height profile over a longer longitudinal section without requiring proportionally longer clamp material.
2Shape
If the wire harness is pressed to reduce height, then interior space is increased, but the wire harness may displace longitudinally
Solution Approach 1:
The binding member simultaneously performs multiple functions: it binds the wire harness to maintain its flattened reduced-height state, and also secures the clamp to the vehicle body. This merging of functions ensures that the wire harness remains stable in both shape and longitudinal position without requiring separate mechanisms.
Solution Approach 2:
The binding member acts as an intermediary element that connects the clamp, wire harness, and vehicle body. It transmits and distributes forces to maintain the wire harness in its pressed state while preventing longitudinal displacement, bridging the interaction between the pressing mechanism and the secured object.
3Stability of the object's composition
If a binding member is used to hold the clamp and wire harness, then the reduced height state is maintained, but the structure becomes more complex
Solution Approach 1:
The binding member is designed as a multi-functional component that simultaneously maintains the flattened state of the wire harness, secures the clamp structure, and prevents longitudinal displacement. This universal application of a single component achieves multiple stability objectives without proportionally increasing structural complexity.

Implementation Method 1
the clamp configured to press-deform the wire harness and press-expand the wire harness in a lateral width direction to grip the wire harness in a state where the wire harness has a reduced height
Implementation Method 2
a binding member configured to bind and hold a part of the clamp and the wire harness having been gripped
Implementation Method 3

AI summary
A wire harness having a round cross-section, a clamp that has an engagement portion for attachment to a vehicle body, a placement portion on which the wire harness is placed, and a pressing portion for pressing the wire harness, and a binding member are used. The pressing portion has pressing body portions opposing in a longitudinal direction of the wire harness, and opposing extending portions for joining the pressing body portions, and can be provisionally combined with the placement portion in a state where the wire harness is pressed to have a reduced height. In the provisionally combined state, the wire harness in the low height state, the placement portion, and the opposing extending portions are bound between the pressing body portions opposing each other.
