Clip Brush With Integrated Channel for Secure Retention

Solution Overview

Problem

Existing brushes with external retaining features are bulky, add weight, increase manufacturing costs, and provide weak retention due to single-point contact, making them undesirable for convenient storage and transport.

Innovation Solution

A brush design with an internal channel and contoured exterior sides that provides an interference fit for secure retention, combined with a secondary retention band for enhanced stability, allowing easy attachment and detachment without additional bulk or weight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external retaining features (straps, clips, clamps) are added to the brush, then retention strength is improved, but device complexity, weight, and manufacturing cost increase

Engineering Contradiction:

Improveretention strengthVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The retaining feature is merged with the handle body itself, forming an integrated structure where the handle body includes a retaining opening and engagement features. This eliminates the need for separate external retaining components while maintaining effective retention functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The handle body serves multiple functions: it provides structural support for the brush, contains the retaining feature for attachment to surfaces, and integrates the engagement mechanism. This multi-functionality reduces the number of separate components needed.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If external retaining features (straps, clips, clamps) are added to the brush, then retention strength is improved, but weight increases

Engineering Contradiction:

Improveretention strengthVSAvoidbrush weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The retaining feature is merged with the handle body itself, forming an integrated structure where the handle body includes a retaining opening and engagement features. This eliminates the need for separate external retaining components while maintaining effective retention functionality.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If external retaining features (straps, clips, clamps) are added to the brush, then retention strength is improved, but manufacturing cost increases

Engineering Contradiction:

Improveretention strengthVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The retaining feature is merged with the handle body itself, forming an integrated structure where the handle body includes a retaining opening and engagement features. This eliminates the need for separate external retaining components while maintaining effective retention functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Device complexity

If a simple hook is used as a retaining feature, then device complexity is reduced, but retention strength deteriorates due to single-point contact

Engineering Contradiction:

Improvestructure complexityVSAvoidretention strength

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The retention mechanism transitions from single-point contact (hook) to surface contact. The retaining opening provides a cavity that accommodates a fastener, creating multiple contact points and distributing the retention force across a larger area, thereby improving retention strength without significantly increasing complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
