Wire Harness Routing With Inward Guide to Prevent Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire harness routing devices face issues with excess length portions getting jammed in the absorbing box, preventing smooth accommodation.
Innovation Solution
A wire harness routing device with a guide portion that changes the direction of the excess length portion to an inward direction using an elastic member, preventing it from being pressed against the side wall and allowing smooth entry into the accommodating portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the excess length portion of the wire harness is pushed in from the entrance toward the distal side of the excess length absorbing box, then the wire harness can be accommodated, but the excess length portion will be jammed in the excess length absorbing box and will not be able to further enter
Solution Approach 1:
A guide portion is introduced as an intermediary element between the entrance and the spirally winding region. This guide portion actively directs the excess length portion of the wire harness into the accommodating space, preventing it from being pushed against the side wall and causing jamming. The guide portion mediates the interaction between the wire harness and the accommodating box, ensuring smooth operation.
2Quantity of substance
If the excess length portion is accommodated by spirally winding in the excess length absorbing box, then the excess length can be absorbed, but the wire harness may be pressed against the side wall and jammed
Solution Approach 1:
The guide portion performs a preliminary action by pre-directing the excess length portion of the wire harness into the correct trajectory before it enters the spirally winding region. This preliminary guidance prevents the wire harness from being improperly positioned or pressed against the side wall during the winding process, ensuring smooth accommodation throughout the entire absorption process.
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
Ensures the excess length portion can be smoothly accommodated within the device, preventing jamming and allowing for efficient routing.
Implementation Method 1
a guide portion that is disposed in the excess length accommodating portion and that is configured to change a direction in which the excess length portion enters the excess length accommodating portion to an inward direction of the excess length accommodating portion by coming into contact with the excess length portion
