Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing demolition tools are specialized in functionality, limiting their effectiveness and requiring laborers to purchase multiple tools for complex projects, which is expensive and inconvenient, and they often lack design characteristics that maximize leverage, momentum, and sharpness for efficient material tearing.
Innovation Solution
A multifunctional demolition tool with a handle and prying head featuring tines mechanically coupled with a cylindrical cross frame, including a tapered base and reinforcing gusset, and a striking head, designed to provide leverage, momentum, and sharpness for tasks like prying, piercing, and hammering, with adjustable bend angles and tine configurations for versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple specialized demolition tools are used to perform different functions (prying, cutting, hammering, breaking), then each function can be performed effectively, but the number of tools required increases, leading to higher cost and reduced ease of operation
Solution Approach 1:
The patent combines multiple demolition functions (prying, cutting, hammering, breaking, puncturing, penetrating) into a single tool by integrating a prying head with multiple tines, a striking head, and a handle with specific bend angles into one unified device, eliminating the need for multiple separate specialized tools
Solution Approach 2:
The demolition tool is designed as a universal multifunctional instrument that can perform prying, cutting, hammering, breaking, puncturing, and penetrating operations through its various components (tines, striking head, handle configuration), allowing a single tool to replace multiple specialized tools
2Device complexity
If a single multifunctional demolition tool is designed to perform multiple functions, then the number of tools required decreases, but the structural complexity and design requirements increase
Solution Approach 1:
The tool is segmented into distinct functional components (prying head with multiple tines, striking head, handle with specific bends) where each segment performs a specific function, allowing the overall structure to be complex yet organized and manageable
Solution Approach 2:
The handle incorporates three-dimensional bend angles (first bend at approximately 90 degrees, second bend at approximately 45 degrees) to optimize leverage and force application in multiple directions, adding spatial dimensionality to the tool's functionality
3Productivity
If traditional demolition tools are used without optimized design characteristics, then manufacturing and operation are simpler, but leverage, momentum, and sharpness are not maximized, reducing productivity
Solution Approach 1:
The tool employs specific geometric parameters (tine angles, handle bend angles of approximately 90 and 45 degrees, tapered base dimensions) to optimize mechanical advantage, leverage, and force distribution, maximizing productivity through precise parameter selection
Solution Approach 2:
The prying head features a substantially cylindrical cross frame with curved surfaces that provide structural strength while optimizing force distribution and leverage points, enhancing the tool's mechanical efficiency
