Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing power tools lack integrated storage solutions for accessory tools, leading to the need for separate storage cases, which can complicate access and maintenance.

Innovation Solution

The power tool incorporates a handle with an internal storage space that is accessible from the rearward end, where the battery receptacle at least partially defines the opening of the storage space, allowing for the secure storage of tool accessories.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If accessory tools are provided separately from the power tool, then the power tool can maintain a simpler structure, but users need separate storage cases which complicates access and maintenance

Engineering Contradiction:

Improvepower tool structureVSAvoidaccess to accessory tools

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The patent combines the storage function for accessory tools directly into the power tool housing. The handle defines an internal storage space that is integrated into the power tool structure, eliminating the need for separate storage cases while maintaining structural simplicity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The power tool housing serves multiple functions: it protects the motor and internal components, provides structural support, and incorporates an internal storage space for accessory tools. This multi-functionality reduces the need for separate storage solutions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Volume of moving object

If accessory tools are stored externally, then the power tool maintains a compact design, but users require additional external storage which reduces convenience

Engineering Contradiction:

Improvepower tool sizeVSAvoidaccessibility of accessory tools

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The storage space for accessory tools is nested within the handle of the power tool. The handle defines an internal cavity that accommodates accessory tools, effectively utilizing the existing structural volume without requiring additional external storage components.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Reliability

If the battery receptacle defines the opening of the storage space, then the storage space is enclosed when the battery pack is coupled, but access to the storage space requires removing the battery pack

Engineering Contradiction:

Improveenclosure of storage spaceVSAvoidtime to access accessory tools

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The battery receptacle and storage space opening are merged into a single structural feature. The battery receptacle at least partially defines the opening of the storage space, creating a unified design where the battery pack serves as a cover for the storage space when attached.

Inventive Principle:

Principle #5Merging (Combining)
