Rotating Chain Repair Block for Easier Breaking and Riveting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chain repair devices are cumbersome due to separate components that require precise assembly for different operations, leading to difficulties in chain maintenance and replacement.
Innovation Solution
A chain replacement apparatus with a rotatable repair block and operation assembly that allows for easy switching between chain breaking, pressing, and riveting operations by rotating the repair block on a body seat, eliminating the need for complex component combinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate components (PBR block, repair blocks, tool body) are used for different chain operations, then the device can perform multiple functions (breaking, pressing, riveting), but the device complexity increases and ease of operation deteriorates due to the need for precise assembly and component selection
Solution Approach 1:
The patent merges the PBR block and repair blocks into a single integrated repair block that can perform breaking, pressing, and riveting operations. The tool body is also integrated to include the combination bore and positioning structures, eliminating the need for separate components and their precise assembly.
Solution Approach 2:
The integrated repair block is designed with universal functionality to perform multiple chain maintenance operations (breaking, pressing, riveting) through a single component. The block can be rotated to different positions within the tool body to access different functional surfaces, allowing one component to replace multiple specialized components.
2Adaptability or versatility
If multiple repair blocks and PBR block combinations are used for different operations, then various chain maintenance functions can be achieved, but the ease of operation deteriorates due to the need for precise component combination and selection
Solution Approach 1:
The patent combines multiple repair blocks and the PBR block into a single integrated repair block that performs all functions. The tool body is also merged to include the combination bore and positioning structures, eliminating the need for separate components and their precise assembly.
Solution Approach 2:
The repair block is designed to be rotatable within the tool body, allowing dynamic repositioning between different operational modes (breaking, pressing, riveting). This rotational capability provides adaptability without requiring complex assembly changes, improving ease of operation while maintaining multiple functional capabilities.
3Adaptability or versatility
If separate components are used that are not normally connected, then the device can be flexible in configuration, but the ease of operation deteriorates due to the need for precise assembly and the risk of incorrect positioning
Solution Approach 1:
The patent merges the previously separate PBR block and repair blocks into a single integrated repair block that performs all functions. The tool body is also integrated to include the combination bore and positioning structures, eliminating the need for separate components and their precise assembly.
Solution Approach 2:
The integrated repair block includes built-in positioning structures (such as positioning grooves or keys) that automatically align with corresponding features in the tool body. This self-positioning capability eliminates the need for precise manual assembly and reduces the risk of incorrect positioning, allowing the block to be easily installed and used without complex configuration.

AI summary
A chain replacement apparatus includes a body seat, an operation assembly, and a repair block. The operation assembly is rotatably disposed on the body seat. The repair block is disposed on the body seat and selectively switched among a removing status, a combining status, and a riveting status, so as to, through the operation assembly, break the chain, press the outer and inner chain plates, and rivet the chain. The repair block rotates about an action axis to be switched among different statuses.
