Flexible Washer Holder Adaptor for Multi-Nose Fastener Guns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastener guns lack a versatile and secure method to accommodate variously sized and shaped nose stems, limiting their compatibility with different washer types, including metallic and plastic washers, during fastening operations.
Innovation Solution
A flexible or semi-rigid washer holder adaptor with a sleeve portion made of RTV silicone rubber or spring steel, featuring magnets for securing metallic washers and a friction fit for non-metallic washers, which can be adjusted to fit different nose stem diameters and shapes, allowing secure mounting to fastener guns and aiding in washer placement on building surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid holder adaptor is used, then it provides stable structure and secure washer retention, but it cannot accommodate variously sized and shaped nose stems of different fastener guns
Solution Approach 1:
The holder adaptor is constructed from flexible or semi-rigid material that can be molded into a desired shape, allowing it to conform to variously sized and shaped nose stems while maintaining structural integrity for secure washer retention
Solution Approach 2:
The flexible material properties of the holder adaptor allow it to change its physical parameters (shape, size) to accommodate different nose stem configurations while maintaining functional stability for washer holding
2Adaptability or versatility
If a universal holder adaptor design is created, then it can work with both metallic and plastic washers, but it increases device complexity
Solution Approach 1:
The holder adaptor is designed with a universal interface that can accommodate both metallic and plastic washers through its flexible material construction, eliminating the need for separate adaptors for different washer types
Solution Approach 2:
The flexible material allows the adaptor to work with both metallic and plastic washers through a single unified design, avoiding the complexity of multiple specialized components
3Adaptability or versatility
If the sleeve portion is made very flexible, then it can fit different nose stem diameters, but it may reduce the secure retention of washers
Solution Approach 1:
The flexible or semi-rigid material properties are carefully selected to provide both the flexibility needed to accommodate various nose stem diameters and the structural integrity required for reliable washer retention
Solution Approach 2:
The flexible sleeve portion is designed with appropriate material properties that balance conformability to different nose stems with sufficient structural strength to securely retain washers during fastening operations

AI summary
An adaptor configured for mounting to a nose stem of a fastener gun, with the adaptor including a flexible elongate body portion that is stretchable over the nose stem of the fastener gun to retain the body portion thereon, and including an end affixed to the body portion, where the end is configured to engage with a mountable building fixture to secure the mountable building fixture to a building surface via a fastener discharged from the fastener gun. The mountable building fixtures may be plastic washers, metallic washers, as well as various plates or hangers, such as joist hangers or truss plates or other such connectors.
