Self-contained Force Magnifying Chisel with Spring-Loaded Striker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chisels require an additional tool for operation, pose a risk of injury due to the need for manual striking, and are limited to specific purposes, necessitating multiple tools for different tasks.
Innovation Solution
A self-contained force magnifying chisel with a built-in striker and spring mechanism that eliminates the need for a separate hammer or mallet and allows for removable bits, enabling single-tool operation and enhanced versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a conventional chisel is used with a separate hammer or mallet, then the mechanical advantage of force magnification is achieved, but the risk of injury to the user's hand increases
Solution Approach 1:
The patent combines the striker and chisel into a single integrated tool. The striker is positioned within the chisel portion, and the spring mechanism is integrated within the same housing, eliminating the need for a separate hammer or mallet and removing the safety hazard of separate striking tools
Solution Approach 2:
The chisel is designed to be self-contained with its own striking mechanism. The spring-loaded striker automatically provides the striking force needed to drive the chisel bit, making the tool self-sufficient and eliminating the need for external striking tools that pose injury risks
2Productivity
If a conventional chisel is used, then the chisel can be operated to cut or shape material, but an additional tool (hammer or mallet) is required
Solution Approach 1:
The patent merges the function of the chisel bit and the striking tool into a single integrated device. The striker, spring mechanism, and chisel portion are combined into one tool, eliminating the need for multiple separate tools and simplifying the operational process
Solution Approach 2:
The integrated chisel design provides multiple functions in one tool: the chisel bit for cutting/shaping, the spring mechanism for force multiplication, and the striker for delivering impact. This multi-functional design replaces the need for separate hammer and chisel tools
3Reliability
If a conventional chisel is made for a specific purpose, then the chisel is optimized for that task, but multiple chisels are needed for different purposes
Solution Approach 1:
The patent segments the chisel into a reusable main body (chisel portion with spring mechanism) and interchangeable bits. Different chisel bits can be attached to the same chisel portion, allowing the user to optimize for different tasks while maintaining a single core tool
Solution Approach 2:
The chisel portion is designed as a universal platform that can accommodate various types of chisel bits. This allows a single chisel handle mechanism to perform multiple functions by simply changing the bit, providing adaptability across different cutting and shaping tasks
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 self-contained design enhances safety by eliminating the risk of injury from manual striking and allows for multiple applications with interchangeable bits, providing a single tool for various tasks while maintaining the mechanical advantage of a chisel.
Implementation Method 1
a spring, at least a portion of which is disposed within the chisel portion and which is attached to the chisel portion and the striker
Data Source
AI summary
The self-contained force magnifying chisel disclosed herein includes a chisel portion, a striker, at least a portion of which is disposed within the chisel portion, and a spring, a least a portion of which is disposed within the chisel portion. The spring attaches to both the chisel portion and the striker. When the striker is pulled by a user, the spring stores mechanical energy. When the user releases the striker, the striker impacts on the chisel portion transferring the mechanical energy stored in the spring into a driving force. The force is magnified by a chisel blade on the chisel portion of the self-contained force magnifying chisel and applied to a workpiece.
