Elastic Guide Member for Nail Fixing Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing assemblies face difficulties in securely attaching to concrete surfaces due to obstacles caused by guide members during fastener striking, leading to reduced penetration and instability, especially on rough surfaces.
Innovation Solution
A fixing assembly with an elastic guide member having a flared guide part and rib-shaped protrusions that allows the nose part of a nailer to guide the fastener effectively, preventing obstruction and ensuring stable attachment by distributing contact area on the workpiece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a guide member is attached to the insertion hole to guide the fastener, then the fastener can be easily targeted and struck, but the guide member becomes an obstacle during striking and reduces the penetrating amount of the fastener
Solution Approach 1:
The guide member is designed with elastic deformation capability, allowing it to dynamically change its state from a rigid guide structure to a deformed state that accommodates the fastener during striking. The guide member elastically deforms when the fastener passes through, preventing obstruction while maintaining guidance functionality.
Solution Approach 2:
The guide member's physical parameters (shape, size) are changed during the striking process through elastic deformation. The guide member transitions from its original configuration to a deformed configuration that allows the fastener to pass through with sufficient penetrating amount, then returns to its original state.
2Area of stationary object
If the entire surface of the fixing that faces the workpiece is brought into contact with the workpiece surface, then coverage is maximized, but the fixing becomes unstable and likely to incline on rough surfaces
Solution Approach 1:
The guide member's distal end portion is designed with a specific local quality (larger outer diameter) that creates a stable engagement interface with the nose part. This localized geometric feature provides rotational stability and proper orientation without requiring the entire fixing surface to contact the workpiece uniformly.
Solution Approach 2:
The guide member features an asymmetric geometry with a distal end portion having a larger outer diameter than other portions. This asymmetric design creates a stable engagement configuration with the nose part, preventing rotation and inclination while maintaining proper orientation during the fastening process.

Function Achieved in This Case
The solution enables reliable and stable securing of objects to concrete surfaces by preventing guide member obstruction and maintaining orientation, even on rough surfaces, with enhanced fastener penetration and reduced risk of inclination.

AI summary
A fixing assembly is adapted to be secured to a workpiece with a fastener that is struck out from a nose part of a nailer. The fixing assembly includes a fixing formed with an insertion hole through which the fastener is to be inserted, and a guide member. The guide member includes a base part fixed to the insertion hole, and a guide part adapted to be elastically engaged with the nose part. An outer diameter of a distal end portion of the guide part is larger than an inner diameter of the nose part.
