Pry Tool Anti-Slip Head with Rugged Curved Bottom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pry tools often slip off objects when a large levering force is applied due to the lack of a secure abutment surface, leading to ineffective prying.
Innovation Solution
The pry tool features a body with a rugged curved bottom surface and strategically placed recesses on its bottom side, which provides a stable and anti-slip interface when abutting a surface, preventing slipping even under significant force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a smooth curved surface is used on the head for abutment, then the pry tool can provide a fulcrum, but the head slips off the object when large levering force is applied
Solution Approach 1:
The bottom side of the head features a rugged curved surface with recesses at specific locations rather than a uniformly smooth surface. This local modification creates high-friction zones at the recesses while maintaining the overall curved geometry needed for fulcrum function, resolving the contradiction between smooth surface operation and slip resistance
Solution Approach 2:
The bottom surface is segmented into multiple recesses distributed along the curved surface. These recesses act as discrete contact points that engage with the object being pried, distributing the levering force across multiple high-friction zones rather than a single smooth contact point, thereby preventing slippage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The anti-slip surface ensures the pry tool maintains contact with the object, allowing for effective prying without slipping, even on uneven surfaces, when a large levering force is applied.
Implementation Method 1
A partial area of the bottom side includes at least one first recess formed therein such that the bottom side has a rugged curved surface. The anti-slip surface ensures the pry tool maintains contact with the object, allowing for effective prying without slipping

AI summary
A pry tool has an anti-slip head. The head has a body having a front end and a rear end and having first and second lateral sides and top and bottom sides extending from the front end to the rear end. The top and bottom sides connect the first and second lateral sides. The bottom side extends curvedly from the front end to the rear end. A partial area of the bottom side includes at least one first recess formed therein such that the bottom side has a rugged curved surface.
