Driving Tool Sub-Magazine Guide Mechanism for Tilted Staple Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving tools for staples face issues with interference between the staple guide and the staples when U-shaped staples are loaded into the main magazine, particularly when staples are tilted, leading to incomplete closure of the magazine end and increased rattling.
Innovation Solution
The driving tool incorporates a guide mechanism with a rail and rail engaging portion to guide the sub-magazine from an opening position to a closing position, ensuring the staple guide is positioned to avoid interference with the staple heads, even when staples are tilted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the clearance between the staple guide and the head of the staple is made small to reduce rattling, then the rattling of staples is reduced, but the staple guide interferes with the staple head when staples are tilted causing the magazine end not to close completely
Solution Approach 1:
The patent makes the staple guide movable relative to the magazine end, allowing it to dynamically adjust its position. When the magazine end closes, the staple guide can move to accommodate tilted staples and avoid interference, while still maintaining sufficient clearance to reduce rattling during normal operation
Solution Approach 2:
The patent introduces a guide mechanism as an intermediary between the staple guide and the magazine end. This guide mechanism includes guide rails and guide grooves that control the movement of the staple guide, enabling it to adapt to tilted staples without causing interference during closure
2Stability of the object's composition
If the staple guide is positioned close to the staple heads to reduce rattling, then the stability of staples is improved, but interference occurs when staples are tilted preventing proper magazine closure
Solution Approach 1:
The staple guide is designed to be movable rather than fixed, allowing it to dynamically adjust its position during magazine closure. This enables the guide to maintain close proximity to staples for stability while moving away when needed to accommodate tilted staples during closure operation
Solution Approach 2:
The patent adds a movement dimension to the staple guide by providing guide rails and grooves that enable the staple guide to move in a direction perpendicular to the magazine closure direction, allowing it to navigate around tilted staples without blocking closure

AI summary
A driving tool comprises a tool main body that includes a driver for driving a U-shaped staple, and a main magazine for housing a plurality of staples that extends from the tool main body. The driving tool also comprises a sub-magazine to which a pusher and a staple guide are attachable. The pusher pushes the staples in the main magazine toward the tool main body. The staple guide is inserted between a pair of legs of the staple in the main magazine. The driving tool also comprises a guide mechanism for guiding the sub-magazine toward the tool main body from an opening position to a closing position with respect to the main magazine. The guide mechanism also guides the sub-magazine in a direction opposite to a driving direction while the sub-magazine moves from the opening position to the closing position.
