Wire Harness Binding Member With Low-Profile Buckle Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belt-type clamps interfere with wire harnesses due to the elastic engagement piece pressing onto the wire when bound, making insertion time-consuming and difficult to automate.
Innovation Solution
A belt-type binding member with a buckle portion positioned lower than conventional designs, featuring a cantilevered elastic engagement piece that extends beyond the buckle connection, allowing it to bend downward and enter a cavity formed by the belt's proximal end branches, reducing interference with the wire harness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the elastic engagement piece is positioned to prevent disengagement when the belt is inserted in the buckle, then the binding member maintains reliable fixation, but the elastic engagement piece interferes with the wire harness and makes insertion time-consuming
Solution Approach 1:
The elastic engagement piece is repositioned from a horizontal orientation to an inclined orientation, extending from the lower-surface portion of the buckle portion toward the upper-surface portion. This dimensional change in orientation allows the engagement piece to prevent disengagement while avoiding interference with the wire harness during insertion, thus resolving the contradiction between fixation reliability and insertion time
2Reliability
If the belt-type clamp uses a conventional buckle portion structure, then the elastic engagement piece can prevent disengagement, but the clamp height increases and reduces space efficiency
Solution Approach 1:
The elastic engagement piece is oriented at an inclination rather than extending horizontally, utilizing the vertical dimension within the buckle portion structure. This allows the engagement piece to maintain disengagement prevention functionality while fitting within a more compact overall height, thus resolving the contradiction between reliability and clamp height
Solution Approach 2:
The elastic engagement piece is designed with elastic properties that allow it to deform during insertion and then maintain engagement to prevent disengagement. This dynamic behavior enables the piece to provide reliable fixation while accommodating a more compact buckle portion structure with reduced height
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
The solution prevents interference from the elastic engagement piece, enabling easier insertion and automation, while allowing the buckle portion to be thinner and reducing the risk of bending, thus enhancing the wire harness's linear retention and space efficiency.
Implementation Method 1
the elastic engagement piece is provided so as to extend beyond a connecting position between the belt portion and the lower surface of the buckle portion in the belt insertion direction of the belt insertion hole, and so as to enter the cavity when a portion on the free-end side is elastically deformed downward

AI summary
Provided is a belt-type binding member including a buckle portion located at a lower position than conventional ones, and a wire harness that is unlikely to receive interference from an elastic engagement piece when bound with a belt. A binding member integrally includes a belt portion and a buckle portion. A proximal end of the belt portion separates into right and left so as to create a cavity therebetween, and the proximal end branched on both the right and the left side is connected to a lower surface of the buckle portion. An elastic locking piece extends beyond a connection position between the belt portion and the lower surface in a belt insertion direction of a belt insertion hole, and enters the cavity when a portion on a free-end side is elastically deformed downward.
