Retained Removal Tool Assembly for Single-Handed Fastener Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand tools for driving fasteners often detach during operation, requiring users to hold both the tool and the driving member, leaving no free hand for other tasks.
Innovation Solution
A removal tool with a retainer attached to a gripped member, featuring a driving member inserted through a through hole and a retainer disposed on the opposite side to prevent disengagement, ensuring stable retention and allowing for single-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hand tool is used to drive the driving member to rotate the fastener, then the fastening operation can be performed, but the driving member easily detaches from the hand tool
Solution Approach 1:
The driving member is inserted into a through hole of the gripped member, creating a nested structure where the driving member is retained within the gripped member. The retainer further secures the driving member by engaging with it from the opposite side, ensuring reliable retention while allowing single-handed operation.
Solution Approach 2:
The retainer acts as an intermediary component between the driving member and the gripped member. It is disposed on the opposite side of the through hole and prevents the driving member from disengaging, thereby solving the detachment problem without interfering with the driving operation.
2Reliability
If the user holds both the hand tool and the driving member to prevent detachment, then the driving member remains secure, but there is no free hand for other operations
Solution Approach 1:
The hand tool (gripped member) and the driving member are merged into a single integrated assembly through the through hole and retainer mechanism. This combination allows the user to operate the tool with one hand while the driving member remains securely attached, freeing the other hand for additional tasks and improving overall productivity.
Solution Approach 2:
The retainer serves as an intermediary that automatically secures the driving member to the gripped member, eliminating the need for the user to manually hold both components. This automated retention mechanism enables single-handed operation and increases operational efficiency.
