Multi-Functional Breaching Tool Combining Sledge Hammer and Rake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing breaching tools are not optimized for efficient and safe entry into buildings and vehicles, particularly in emergency situations, as they lack a comprehensive solution for quickly breaking through windows and doors while effectively clearing glass fragments and navigating various door materials.
Innovation Solution
A specialized breaching tool with a sledge hammer head, a curved chisel tail end, and a rake with teeth for scraping out glass, designed to efficiently break through windows and doors, and penetrate various materials, including plastic, wood, and metal, while allowing for the removal of fasteners and cleaning of glass edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional breaching tools are used to break through windows and doors, then entry can be achieved, but the process is time-consuming and requires multiple separate tools for different functions
Solution Approach 1:
The patent combines multiple breaching functions (sledgehammer for breaking glass, rake for clearing fragments, chisel for penetrating doors, claw for removing fasteners) into a single multi-functional tool head that attaches to one handle, eliminating the need for multiple separate tools and improving breaching efficiency
Solution Approach 2:
The tool head is designed with four different functional elements (sledgehammer, rake, chisel, claw) that can all be used by a single operator, making the tool universal for various breaching operations including window breaking, glass clearing, door penetration, and fastener removal
2Adaptability or versatility
If multiple separate breaching tools are carried, then comprehensive functionality is achieved, but weight and portability are compromised
Solution Approach 1:
By merging four separate breaching tools (sledgehammer, rake, chisel, claw) into one integrated tool head, the total weight that must be carried and manipulated is reduced, improving portability while maintaining comprehensive breaching capability
Solution Approach 2:
The multi-functional tool head allows a single operator to perform all breaching operations with one tool instead of carrying multiple tools, reducing the overall weight burden while maintaining adaptability across different breaching scenarios
3Productivity
If traditional tools are used for window breaching, then glass can be broken, but safe clearing of glass fragments requires additional time and tools
Solution Approach 1:
The tool head integrates both the sledgehammer function for breaking glass and the rake function for clearing fragments into a single tool, allowing the operator to immediately clear hazardous glass fragments after breaking windows, reducing exposure time to glass hazards
Solution Approach 2:
The rake element is designed to immediately follow the sledgehammer action in clearing glass fragments from the window frame, maintaining continuous useful action without requiring the operator to switch tools or pause, thereby improving entry speed while managing glass hazards

AI summary
A breaching tool for use by law enforcement or emergency personnel has at one end of its handle a sledge hammer and a multi-toothed rake effective to scrape and clean broken glass from a window frame of a building or an automobile. At an opposite or rear end of the handle a tapered chisel tail, preferably with a claw for pulling nails or other fasteners.
