Compact Chain Repair Tool with Rotatable PBR Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current chain repair tools are cumbersome, requiring multiple parts and confusing configurations for attaching, detaching, and riveting chain links, leading to potential misplacement of parts and user confusion during operations like breaking, pressing, and riveting.
Innovation Solution
A single, compact chain repair tool with a PBR block that allows for pressing, breaking, and riveting operations with minimal reconfiguration, featuring a tapered body bolt, domed breaking pin, and dual-sided rivet tips for both hollow nose and quad stake rivets, with clear markings and integrated storage for accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional chain repair tools are used with multiple parts and configurations, then comprehensive repair functions are achieved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple repair functions (pressing, breaking, riveting) into a single integrated tool body with a rotatable block that can be positioned in different orientations. Each orientation provides a different function, eliminating the need for multiple separate tools or complex reconfigurations while maintaining comprehensive repair capabilities
Solution Approach 2:
The tool body with rotatable block serves multiple purposes: pressing side plates when block is in first orientation, breaking chains when in second orientation, and riveting when in third orientation. This universal design allows one tool to perform all necessary chain repair operations without requiring multiple specialized tools
2Adaptability or versatility
If traditional chain repair tools with multiple parts are used, then all repair operations can be performed, but ease of operation and reliability worsen due to part misplacement
Solution Approach 1:
By merging all repair functions into a single integrated tool with a rotatable block, the patent eliminates multiple loose parts that can be misplaced. The user simply rotates the block to the appropriate orientation for the desired operation, making the tool easier to operate and more reliable
Solution Approach 2:
The rotatable block provides dynamic reconfiguration of the tool's function through simple rotation rather than assembly/disassembly of multiple parts. This dynamic adjustment mechanism maintains versatility while significantly improving ease of operation and reducing user confusion
3Adaptability or versatility
If traditional chain repair tools are used, then comprehensive repair capabilities are achieved, but manufacturing precision and ease of manufacture worsen
Solution Approach 1:
The patent merges multiple repair functions into a single tool body with a rotatable block, reducing the total number of parts that need to be manufactured, inventoried, and assembled. This integration simplifies manufacturing processes while maintaining comprehensive repair capabilities
