Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing power tools lack an effective and easily replaceable structure for holding spare tip tools, which can become damaged and may come into contact with the floor when the tool is placed down, especially when multiple types of work require different tip tools.

Innovation Solution

A tip tool holder attachable to a power tool, featuring a nail portion for insertion into an attachment hole and an accommodation portion that holds the tip tool upright, preventing contact with the floor, with a hook attachment system allowing for easy mounting and detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a holding structure for spare bits is integrated into the power tool, then the bit can be held securely, but the structure may be damaged and is difficult to replace

Engineering Contradiction:

Improveholding structure durabilityVSAvoidholding structure replaceability

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The holding structure is divided into two separate components: a holder that attaches to the power tool and a separate bit storage portion. This segmentation allows the holder to be replaced independently if damaged, without replacing the entire power tool, thus improving ease of repair while maintaining secure holding capability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The holder acts as an intermediary component between the power tool and the bit storage function. It can be attached to and detached from the power tool, providing a replaceable interface that protects the main tool while enabling easy replacement of the holding structure itself

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the power tool is placed on the floor surface, then the tool can be stored conveniently, but the held tip tool may come into contact with the floor and be damaged

Engineering Contradiction:

Improvetool storage convenienceVSAvoidfloor contact damage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The holder is designed to extend the bit storage in a direction perpendicular to the power tool's longitudinal axis, creating a third-dimensional storage solution. When the tool is placed on the floor, this extended structure positions the bit tip away from the contact surface, preventing damage while maintaining convenient storage

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If multiple types of work are performed using one power tool, then tool versatility is improved, but the need to replace tip tools increases

Engineering Contradiction:

Improvework type flexibilityVSAvoidbit replacement time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The holder is pre-equipped with storage capacity for multiple spare bits, allowing the user to prepare and store different bit types in advance. When work requirements change, the user can quickly select and install the needed bit from the pre-stored options, reducing replacement time while maintaining versatility

Inventive Principle:

Principle #10Preliminary action

AI summary

A tip tool holder (30) includes a nail portion (31) to be inserted in an attachment hole formed in a power tool, an accommodation portion (32) capable of accommodating a tip tool, and an opening (33) opposite to the nail portion. The accommodation portion accommodates the tip tool such that an axis of the tip tool is substantially perpendicular to a direction in which the nail portion and the opening face each other. The tip tool holder includes a first arm (34a) and a second arm (34b) opposite to each other. The opening is included in the first arm while the nail portion is provided to the second arm.
