Solution Overview

Problem

Traditional breaching tools are cumbersome and difficult to transport, leading to their abandonment by public safety personnel, necessitating unsafe and damaging improvised methods for forced entry.

Innovation Solution

A collapsible breaching tool that can be expanded for use and compressed for transport, featuring a tool head, handle, and interchangeable handle tubes with threaded connections for easy assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If traditional breaching tools are used, then breaching function is achieved, but weight and bulk increase making them difficult to transport

Engineering Contradiction:

Improveweight of breaching toolVSAvoidease of transport

Core Design Contradiction:

Weight of moving objectVSEase of operation

Solution Approach 1:

The breaching tool is divided into multiple segments including a head assembly, intermediate section, and handle assembly that can be separated from each other. This segmentation allows the tool to be disassembled into smaller, more manageable components for transport while maintaining full functionality when assembled.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The collapsible handle assembly features telescoping sections where one tube slides within another, similar to nested dolls. This nesting mechanism reduces the overall length and bulk of the tool during transport while allowing full extension during breaching operations.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of manufacture

If traditional breaching tools are used, then breaching function is achieved, but device complexity increases

Engineering Contradiction:

Improveease of assemblyVSAvoidstructural complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

By dividing the tool into standardized segments with consistent connection interfaces, the design simplifies manufacturing while enabling complex functionality. Each segment can be manufactured independently using standard processes, then assembled through straightforward connection mechanisms.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The tool employs universal connection features and interchangeable components that serve multiple functions. The same connection mechanism is used throughout the assembly, and components like the head assembly can potentially interface with different handle configurations, reducing overall system complexity through standardization.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If breaching tools are made collapsible, then transportability improves, but connection reliability must be maintained

Engineering Contradiction:

Improveease of transportVSAvoidconnection reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The connection features are pre-configured and pre-aligned in each segment, ensuring that when segments are joined, the connection is immediately reliable without requiring complex alignment procedures. This preliminary preparation of connection interfaces maintains reliability while enabling easy assembly and disassembly for transport.

Inventive Principle:

Principle #10Preliminary action
