Wire Harness Ring Binding Layout for Shift-Resistant Bundling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire harness manufacturing apparatuses either take too long to bind wires due to winding adhesive tape one location at a time or lack a fixing mechanism for helically wound filaments, leading to potential shifts in position and reduced binding force.
Innovation Solution
A wire harness binding apparatus that uses a flexible wire rod to form a binding material by successively creating ring-shaped parts along the wire harness, coupling adjacent parts to maintain position and binding force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If adhesive tape is wound around wires one location at a time, then the binding work can be automated, but the process becomes time-consuming and productivity decreases
Solution Approach 1:
The patent implements continuous winding of adhesive tape around the wire bundle by moving the tape supply unit along the longitudinal direction, eliminating the stop-start process of traditional methods. The tape is continuously supplied and wound while the supply unit traverses the length of the wire bundle, maintaining continuous useful action throughout the binding process.
Solution Approach 2:
The binding process is segmented into multiple winding locations along the longitudinal direction of the wire bundle. The tape supply unit stops at predetermined intervals to wind tape around the bundle at each location, then moves to the next location. This segmentation allows automated binding at multiple points simultaneously, improving overall productivity compared to single-location binding.
2Productivity
If filament is helically wound around wires, then binding speed increases, but the filament position shifts and binding force decreases due to lack of fixing mechanism
Solution Approach 1:
Adhesive tape is applied to the wire bundle before the helical winding of the filament. The tape serves as a preliminary fixing layer that secures the filament in place as it is wound, preventing position shifts. This preliminary action ensures that the binding force remains stable throughout the process, addressing the reliability issue while maintaining high binding speed.
3Adaptability or versatility
If manual binding is performed by workers, then flexibility in handling different wire configurations is maintained, but the process becomes time-consuming and quality varies
Solution Approach 1:
The apparatus incorporates movable components including the tape supply unit that can move in both longitudinal and lateral directions, and the wire bundle can be fed continuously through the system. This dynamic design allows the automated system to adapt to different wire configurations and lengths, maintaining versatility while achieving consistent high-speed binding quality throughout the process.

AI summary
Provided is a wire harness binding apparatus that is capable of automating and speeding up the work of binding a plurality of wires with a binding material by successively binding the wires with the binding material, and that forms a wire harness capable of suppressing a decrease in the binding force that binds the wires. The apparatus includes a wire rod supply unit for supplying a wire rod near an object to be bound, and a ring shape forming unit for forming a ring-shaped part by curving a portion of the wire rod supplied from the wire rod supply unit. The ring shape forming unit successively forms a plurality of ring-shaped parts with the wire rod supplied from the wire rod supply unit, arranges the plurality of ring-shaped parts along the longitudinal direction of the object to be bound, and forms a binding material by connecting adjacent ring-shaped parts along the longitudinal direction of the object to be bound.
