Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detaching wooden structures made by nailing wooden boards and slats are laborious and inconvenient, often causing damage to the structure and risking operator injury, with no suitable pry tools available to mitigate these issues.
Innovation Solution
A pry tool with a special angle design featuring a body with a base and shank, a claw member, and a fixing member, allowing for easy application of force and clamping of wooden slats, which reduces operator strain and minimizes damage to the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wooden board or wooden slat is used as a pry bar, then the operation can be performed, but the operator must apply excessive force manually which is laborious and could damage the detached wooden boards
Solution Approach 1:
The invention changes the geometric parameters of the pry tool by designing a base with a specific arcuate bottom face and defined contact point, and positioning the shank at optimized angles (15°-25° relative to the second axis) to achieve optimal leverage and force distribution, thereby reducing manual effort and preventing damage to wooden structures
Solution Approach 2:
The base includes an arcuate bottom face with a contact point that provides curved surface contact with the working plane, distributing force more evenly and preventing concentrated stress that could damage the wooden boards being detached
2Productivity
If an iron hammer is used to strike the wood structure, then the wooden slats can be separated, but the wooden slat would be injured by the hammer and the operator has to bend down or squat which is laborious
Solution Approach 1:
The pry tool serves as an intermediary between the operator and the wooden structure, providing a controlled mechanical leveraging system that separates wooden slats without direct hammer strikes, thereby preventing injury to the wood while maintaining detachment efficiency
Solution Approach 2:
The invention replaces the impact-based mechanical system (hammer striking) with a lever-based mechanical system (pry tool with base and shank at optimized angles), achieving the same detachment function without damaging the wooden slats
3Productivity
If traditional pry methods are used, then the wooden structure can be detached, but the operator must squat during operation which is laborious and relatively inconvenient
Solution Approach 1:
The pry tool design with its optimized angle geometry and contact point positioning creates a balanced leverage system that distributes force evenly, allowing the operator to work from a standing position without bending or squatting, thereby improving both convenience and operational efficiency
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 pry tool enables efficient detachment of wooden structures with reduced operator effort and minimized damage, allowing for easier handling and installation of wooden boards without the need for bending or squatting.
Implementation Method 1
the operator can apply force easily when the contact point defined by the arcuate bottom face is used as a fulcrum on the working plane

AI summary
A pry tool includes a body having a base with a through-hole extending along a first axis and a through-slot extending perpendicularly to the first axis. The base has an arcuate bottom face defining a contact point for contacting with a working plan. A second axis intersects with the first axis at an intersection and passes through the contact point. A third axis intersects with the second axis at the center of curvature of the arcuate bottom face. An angle between the second and third axes is 5°-10°. A shank extends from the base along a fourth axis intersecting with the first axis at the intersection. An angle between the second and fourth axes is 15°-25°. A claw member is coupled to the through-slot. A fixing member is securely mounted in the through-hole and abuts against the claw member.
