Wire Harness Protector Guide-Groove Locking for One-Step Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire harness protectors require separate operations for inserting engagement claws into holes and closing the base member, making the attachment process complicated.
Innovation Solution
A protector design featuring guide grooves and projections that allow the cover member to be attached to the base member in a single motion, with a lock portion that regulates movement and facilitates simultaneous locking and closure of the cover opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate operations are used for inserting engagement claws into engagement holes and closing the base member opening, then the locking and closing functions can be independently achieved, but the attachment operation becomes complicated
Solution Approach 1:
The patent combines the locking function and closing function into a single integrated operation. The engagement claw is designed to simultaneously perform both locking (by engaging with the engagement hole) and closing (by pushing the cover member to close the opening) when inserted in one motion. This merging of functions resolves the contradiction by achieving reliable locking while simplifying the attachment operation to a single action.
2Ease of operation
If the cover member is moved to attach to the base member, then the attachment is secured, but the operation requires multiple separate steps
Solution Approach 1:
The attachment mechanism is segmented into distinct functional elements: the engagement claw with insertion portion for locking, and the push portion for closing. The base member is segmented with an engagement hole for locking and an opening for closing. This segmentation allows each element to perform its specific function while working together in a single integrated operation, reducing overall device complexity while maintaining ease of operation.
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
Simplifies the attachment operation by integrating the locking mechanism into the attachment process, ensuring secure attachment of the cover member to the base member while maintaining structural integrity.
Implementation Method 1
the lock portion is formed elastically deformable, and comes into contact with each of the guide projections in an upper/lower direction to be in a retreating state while the cover member is moving along the attachment direction
Implementation Method 2
the wall faces an attachment direction-side end of each of the guide projections in the attachment direction, regulating movement of the cover member in the attachment direction
Implementation Method 3
the lock portion is in the advancing state when the cover member is moved to the attachment position, and faces a detachment direction-side end of each of the guide projections in the detachment direction, regulating movement of the cover member in the detachment direction

AI summary
A protector includes a base member and a cover member. The base member includes a pair of guide grooves extending along an attachment direction in which the cover member is attached to the base member and disposed on respective bilateral sides in a width direction perpendicular to the attachment direction, walls facing attachment direction-side ends of guide grooves in the attachment direction, and lock portions facing detachment direction-side ends of the guide grooves in a detachment direction.
