Multi-Function Hand Tool with Nested Rotational Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-function hand tools do not adequately meet the needs of rescuers and first responders, who require specialized tools that are compact and versatile to handle various emergency situations without posing a risk to those being rescued.
Innovation Solution
A multi-function hand tool with a body featuring internal and external cavities, a cutting mechanism, a rotational tool with grasping members and a sharpened edge, and dual contact tips for applying blunt force, designed to be compact and usable in both retracted and extended positions, with a utility cavity for interacting with specific devices like oxygen tank valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-function hand tool includes multiple tools and instruments, then the versatility and utility are improved, but the bulk and size of the design worsen
Solution Approach 1:
The patent implements nesting by placing a rotational tool inside a cavity within the body of the hand tool. The rotational tool can be rotated between a retracted position within the cavity and an extended position outside the cavity, allowing multiple functions to be contained in a compact form factor.
Solution Approach 2:
The patent creates a multi-functional tool by combining a body with an internal cavity, a cutting means in a second cavity, a rotational tool with multiple configurations, and dual contact tips. This single device performs cutting, rotational operations, and blunt force application, eliminating the need for multiple separate tools.
2Force
If larger instruments are used for rescue operations, then the force and capability are improved, but the risk of harm to the person requiring rescue worsens
Solution Approach 1:
The patent applies local quality by providing a grasping orifice on the body that allows rescuers to insert a finger for enhanced grasping and control. This localized feature improves the ability to apply force precisely where needed while maintaining overall tool compactness and safety.
Solution Approach 2:
The dual contact tips serve as intermediaries that allow rescuers to apply blunt force in a controlled manner. The tips concentrate force at specific points for tasks like breaking glass or opening locks, reducing the risk of unintended harm compared to using larger, less controlled instruments.
