Wiring Protector Cover With Movable Insertion Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased thickness of wiring materials due to more electric circuits in vehicles necessitates longer routing times, which is exacerbated by the lack of space for passage within existing protectors, making it difficult to enlarge the protectors without altering their external dimensions.
Innovation Solution
A protector design featuring a case main body with guide spaces and a cover member that includes movable and rotatable parts, allowing for an insertion space to be dynamically adjusted to accommodate wiring extensions, thereby facilitating easier passage of thicker wiring materials without changing the protector's external size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the protector size is increased to secure space for passing wiring material through, then the routing work becomes easier, but there is no space around the protector to accommodate the increased external dimensions
Solution Approach 1:
The cover member is designed with a movable part that can move in the orthogonal direction relative to the cover main body part, transforming the static insertion space into a dynamic one that can be adjusted during routing operations. This allows the insertion space to expand when needed for passing wiring material while maintaining compact external dimensions when the movable part is in its retracted position
Solution Approach 2:
The movable part moves in the orthogonal direction (width direction) to create additional passage space, utilizing a different spatial dimension to resolve the contradiction between needing larger passage space and maintaining compact external dimensions in the longitudinal direction
2Volume of moving object
If the external size of the protector is changed to increase insertion space, then wiring material passage becomes easier, but the external dimensions cannot be altered due to space constraints
Solution Approach 1:
The cover member incorporates a movable part that dynamically adjusts the insertion space volume by moving in the orthogonal direction, allowing the internal passage space to vary without changing the external longitudinal dimensions of the protector
Solution Approach 2:
The movable part is positioned specifically to locally expand the insertion space in the width direction where wiring material passage is needed, while the rest of the protector maintains its original compact external dimensions
3Adaptability or versatility
If the number of electric circuits is increased to accommodate more electric devices, then the functionality of sliding seats and doors is improved, but the wiring material outer diameter increases making routing more time-consuming
Solution Approach 1:
The dynamic movable part allows the insertion space to be easily adjusted to accommodate wiring materials of varying diameters, reducing the time required for routing thicker wiring materials that result from increased electric circuits
Solution Approach 2:
The guide space parts and cover parts provide uniform guidance and protection for wiring materials of different thicknesses, ensuring consistent and efficient routing regardless of the wiring material outer diameter

AI summary
A protector includes a case main body and a cover member. The cover member includes the cover main body part, the first cover part, and the second cover part. The first cover part and the second cover part are at the positions overlapping with each other in the longitudinal direction when viewed from the lateral direction of the cover main body part, and form an insertion space for passing a third extension part of a wiring material WH through in the lateral direction when viewed from the orthogonal direction of the cover main body part. The first cover part includes a movable part that is movable in the orthogonal direction with respect to the cover main body part when viewed from the lateral direction of the cover main body part, and a hinge part that rotatably connects the cover main body part and the movable part.
