Fastener Support Tab Structure for Stable Driving and Compact Coils
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastener supports interfere with the driving posture of fasteners, leading to inaccurate driving due to instability, and increasing the outer diameter when coupled fasteners are wound in a spiral shape, reducing the number of fasteners that can be loaded.
Innovation Solution
A fastener support design featuring a plate-shaped member with first and second tabs that detachably support fasteners, allowing for a reduced outer diameter when coupled and wound in a coil shape while maintaining stable driving posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fastener is supported at a position largely separated from the fastener support, then the head portion of the fastener is hardly influenced by the fastener support and driving posture is stabilized, but the radius increases when the coupled fastener is wound in a spiral shape, resulting in a reduction in the number of fasteners that can be loaded into the magazine
Solution Approach 1:
The fastener support is divided into a plate-shaped main body and multiple tabs (first tab and second tab) that are erected from different portions of the plate. Each tab independently supports a fastener at an optimal position, allowing the fasteners to be stabilized without requiring large separation distances. This segmentation enables compact arrangement while maintaining driving posture stability.
Solution Approach 2:
The invention utilizes the vertical dimension by erecting tabs from the plate-shaped support in the upper-lower direction. This allows fasteners to be supported at elevated positions above the plate surface, providing sufficient separation from the plate while maintaining a compact horizontal footprint. The fasteners are positioned in the upper-lower direction rather than being spread out horizontally, enabling stable driving posture without increasing the radial dimension.
2Quantity of substance
If the fastener is supported close to the fastener support, then the outer diameter is reduced when coupled fasteners are wound in a spiral shape, but the head portion of the fastener is easily influenced by the fastener support, leading to unstable posture and inaccurate driving

AI summary
A fastener support includes: a plate-shaped member having a first portion and a second portion; a first tab erected from the first portion and having a first support portion supporting a first position of a fastener; and a second tab erected from a lower end of the second portion and having a second support portion supporting a second position of the fastener. The first portion has a first opening. The second portion has a second opening which allows at least a part of the fastener to be visually recognized from the rear. The first tab includes a pair of first leg portions erected from the first portion with the first opening interposed therebetween. The second tab includes a pair of second leg portions erected from the lower end of the second portion with the second opening interposed therebetween.
