Rotatable Dual-Head Pry Tool for Safe Leverage Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pry tools with dual heads are prone to scratching users due to sharp edges, requiring one hand to grip inefficiently and risking injury.
Innovation Solution
A dual-headed pry tool with rotatable heads that pivotally connect, allowing one head to rotate relative to the other, featuring a locking mechanism to prevent detachment and a resilient member for controlled rotation, enabling efficient force application without direct contact with sharp edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users grip on the claw not used for prying to apply force efficiently, then force application efficiency is improved, but user safety deteriorates due to risk of scratching from sharp edges
Solution Approach 1:
The second tool component is made rotatable relative to the first tool component about a pivot axis, allowing the tool heads to dynamically change orientation. This enables the user to position the non-using tool head away from the gripping hand, eliminating the scratching risk while maintaining efficient force application through the lever arm
Solution Approach 2:
The rotation capability adds a rotational degree of freedom in the third dimension, allowing the tool heads to be oriented at different angles relative to the pivot axis. This dimensional change enables the user to configure the tool in a safe orientation where the non-using claw does not contact the gripping hand
2Adaptability or versatility
If dual-headed pry tool is used to improve versatility, then adaptability is improved, but device complexity increases due to additional components and connections
Solution Approach 1:
The pry tool is divided into two separate tool components, each with its own tool head and pivot connection. This segmentation allows each component to be independently designed and positioned, providing versatility while keeping the connection mechanism simple and modular
Solution Approach 2:
Each tool component is designed to be functionally complete on its own, with a tool head capable of prying operations. The universal design allows either component to be used independently or together, maximizing versatility without requiring complex integration mechanisms

Function Achieved in This Case
Enables efficient force application without risking injury from sharp edges, enhancing user safety and operational efficiency by allowing one head to face opposite the pulling surface for optimal leverage.
Implementation Method 1
a resilient member for controlled rotation
Implementation Method 2
The second pivot connection is pivotally connected to the first pivot connection to allow the first and the second tool components to pivotally connect with each other

AI summary
A dual-headed pry tool with rotatable head includes a first tool component provided with a first tool head and a first pivot connection, and a second tool component provided with a second tool head and a second pivot connection. The second pivot connection is pivotally connected to the first pivot connection. The second tool component is rotatable relative to the first tool component about a pivot axis which extends along a longitudinal direction of the first tool component. Each of the first and the second tool heads has an orientation with respect to the pivot axis, and a relative angle between the orientations of the first and the second tool heads changes as the second tool component rotates relative to the first tool component.
