Movable Holding Bracket for Fastening Tool Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening tools face challenges in efficiently attaching metal framing members, such as vertical studs to horizontal tracks, due to the need for precise alignment and holding of overlapping portions for effective fastening, often requiring two hands or additional tools.
Innovation Solution
A holding bracket is designed for attachment to fastening tools, featuring a mounting portion, an extension portion, and a holding arm with a gap configured to receive overlapping portions of the stud and track, allowing for one-handed operation and precise alignment before firing a fastener to secure them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional fastening tools are used without a holding bracket, then the tool structure remains simple, but the alignment precision and holding capability of overlapping portions deteriorate
Solution Approach 1:
A holding bracket is introduced as an intermediary component between the fastening tool and the workpieces. The bracket includes a holding arm with a gap that receives overlapping portions of members, providing precise alignment and secure holding during the fastening operation. This mediator enables one-handed operation while maintaining accurate positioning of the workpieces.
2Ease of operation
If additional tools or hands are used to hold members, then the holding capability improves, but the operation complexity and time consumption increase
Solution Approach 1:
The holding bracket merges the holding function with the fastening tool by attaching the holding arm to the tool body. This integration allows the single tool to simultaneously hold and fasten overlapping portions of members, enabling one-handed operation without requiring separate holding tools or additional hands.
Solution Approach 2:
The fastening tool is enhanced with multi-functionality by incorporating the holding bracket. The tool now performs both holding/alignment and fastening functions through its integrated components, eliminating the need for separate tools and simplifying the overall operation to a single-handed process.
3Adaptability or versatility
If the holding bracket uses a fixed structure, then the manufacturing simplicity is maintained, but the adaptability to different member configurations is reduced
Solution Approach 1:
The holding bracket incorporates a movable holding arm that can be adjusted along the extension portion. This dynamic structure allows the gap to be repositioned to accommodate different member configurations, thicknesses, and overlap distances, providing versatility while maintaining a relatively simple manufacturing process through linear movement mechanisms.

AI summary
A movable holding bracket is provided for attachment to a fastening tool having a nosepiece for driving a fastener, the holding bracket configured for holding overlapping portions of two members to be fastened to one another, the bracket including a fixed portion configured for attachment to a workpiece contact element of the tool, and a movable portion movably attached to said fixed portion. A holding arm is attached to the movable portion and defines a gap configured for holding the overlapping portions of the two members for insertion of a fastener driven from the tool nosepiece.
