Solution Overview

Problem

Existing tool accessory holders are limited in their ability to efficiently organize and transition between storage in a case and use with a power tool, lacking a seamless integration system.

Innovation Solution

A tool accessory holder with a body that includes first and second retainers, allowing it to be coupled to both a tool accessory case and a power tool, featuring projections and bores for secure attachment, and compartments for organizing various tool accessories.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a tool accessory holder is designed to be retained in a storage case, then organization and storage efficiency are improved, but the ability to quickly transfer to and from a power tool is reduced

Engineering Contradiction:
Improvestorage organizationVSAvoidtransfer speed
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The tool accessory holder is designed with dual coupling capabilities: a first retainer for coupling to the storage case and a second retainer for coupling to the power tool. This multi-functional design allows the same holder to serve both storage and operational functions, enabling quick transfer between storage and tool without requiring separate holders for each purpose.

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

2Ease of manufacture

If multiple tool accessories are held in separate compartments, then organization is improved, but the holder complexity increases

Engineering Contradiction:
Improveaccessory organizationVSAvoidholder structure
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The holder body is divided into multiple compartments, each capable of receiving and organizing different tool accessories. This segmentation allows for systematic organization of various accessories while maintaining a relatively simple overall holder structure that doesn't significantly increase complexity.

Inventive Principle:
Principle #1Segmentation
