Bend Protector Pocket Design for Wire Housing Workability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bend protectors face difficulties in housing electrical wires in a bent state, particularly due to the thickness of the wires, which leads to deteriorated workability during the bending process.
Innovation Solution
A bend protector design featuring an electrical wire inlet, outlet, and a bend holder with a pocket portion that allows the wire to be gently bent within an internal space with a greater distance than the gap between the first and second walls, reducing the need for excessive bending and improving workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electrical wire is bent in a narrow space between the first wall and the second wall, then the bend protector can maintain a compact structure, but the workability for housing the electrical wire deteriorates
Solution Approach 1:
The pocket portion extends in a direction intersecting with the direction from one side to the other side (transverse direction), creating additional spatial dimension for wire bending. This allows the wire to be bent gently within the pocket portion rather than being constrained to bend only in the narrow space between first and second walls, thus improving workability while maintaining compact overall structure
2Ease of operation
If the electrical wire is bent excessively to fit in the bend protector, then the wire can be housed in the bent state, but the workability for housing the wire deteriorates
Solution Approach 1:
The pocket portion provides increased internal space with greater distance between walls in the transverse direction, changing the spatial parameters available for wire bending. This allows the wire to be bent with a gentler radius and less excessive bending, improving both workability and bending precision simultaneously

AI summary
A bend protector for holding an electrical wire in a bent state includes: an electrical wire inlet provided on one side and formed as an inlet of the electrical wire; an electrical wire outlet provided on the same side as the electrical wire inlet and formed as an outlet of the electrical wire; and a bend holder provided on the other side opposite to the one side so as to hold the electrical wire in the bent state, in which the bend holder includes: a pocket portion formed by a first wall and a second wall extending in a direction intersecting with respect to a direction from the one side toward the other side, and the pocket portion includes an internal space, and the internal space has a part having a distance greater than a distance between the first wall and the second wall.
