Solution Overview
Problem
Existing pry tools with dual heads are prone to scratching users due to sharp corners, necessitating a design that allows for efficient force application without user injury.
Innovation Solution
A dual-headed pry tool with rotatable heads, featuring pivot connections and anti-disengagement mechanisms to prevent detachment, enabling efficient force application and user safety by allowing tool heads to pivot and orientate relative to each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users grip on the claw to apply force efficiently, then force application efficiency is improved, but users are easily scratched by the flat and sharp corners of the claw
Solution Approach 1:
The claw is designed to be rotatable relative to the shaft, allowing the user to dynamically adjust the claw's orientation. This enables the user to grip the shaft at optimal positions for force application while the claw can rotate to present different angles, avoiding contact between the user's hand and the sharp corners during operation.
Solution Approach 2:
The pry tool is divided into functionally independent segments: a shaft for force application and a claw for prying operations. The claw is coupled to the shaft through a rotatable connection, allowing independent movement of each component. This segmentation enables the user to grip the shaft while the claw operates separately, eliminating the hazard of sharp corners contacting the user's hand.
2Device complexity
If a dual-headed pry tool is designed with fixed heads, then structural simplicity is maintained, but the tool lacks adaptability for different prying orientations
Solution Approach 1:
The second tool component is designed to rotate relative to the first tool component about a pivot axis, transforming the structure from fixed to dynamic. This rotational capability allows the second tool head to assume multiple angular orientations, providing adaptability for different prying directions while maintaining a relatively simple overall structure through the use of a single pivot connection.

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.
