Solution Overview

Problem

Existing fastener setting tools require multiple magazines or tools for different diameter fasteners, leading to inefficiency and increased time due to the need for distinct arrangements for proper feed, which is undesirable.

Innovation Solution

A carrier strip system with discrete strips having complementary internal features for different diameters but identical external dimensions, allowing different diameter fasteners to be used in a single setting tool magazine by matching the smaller diameter strip's dimensions to the larger diameter fastener's register, enabling secure engagement and alignment within the magazine.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple magazines or setting tools are used for different diameter fasteners, then proper feed and alignment are ensured, but device complexity and time for replacement increase

Engineering Contradiction:
Improveproper feed and alignmentVSAvoidmultiple magazines or tools
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a universal magazine system where a single magazine can accommodate multiple fastener diameters through interchangeable carrier strips. The carrier strips have external dimensions that match the magazine's carrier strip register, allowing them to be used in the same magazine position while having internal features tailored to different fastener diameters. This eliminates the need for multiple dedicated magazines for different fastener sizes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent divides the fastener holding function into separate carrier strips that can be independently selected and exchanged. Each carrier strip is a discrete component with specific internal dimensions for a particular fastener diameter, but standardized external dimensions for magazine compatibility. This segmentation allows the system to handle multiple fastener types through modular carrier strip selection rather than requiring entirely separate magazines.

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple magazines are used for different diameter fasteners, then proper feed is ensured, but time for magazine replacement increases

Engineering Contradiction:
Improveproper feedVSAvoidmagazine replacement time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent enables operators to pre-select the appropriate carrier strip for the required fastener diameter and have it ready for quick exchange. The standardized external dimensions and register interface allow for rapid insertion and removal of carrier strips without requiring magazine replacement, significantly reducing the time penalty associated with changing fastener types.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If distinct arrangements are used for different diameter fasteners, then proper feed is ensured, but operational efficiency decreases

Engineering Contradiction:
Improveproper feedVSAvoidoperational efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The unified magazine system with interchangeable carrier strips allows a single magazine to perform multiple functions - accommodating different fastener diameters without requiring physical replacement of the magazine itself. This increases operational efficiency by eliminating the need to switch between multiple dedicated magazines while maintaining reliable feed and alignment for each fastener type.

Inventive Principle:
Principle #6Universality (Multi-functionality)
