Adjustable Chain Tool With Reversible Stopper for Multi-Speed Chains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chain tools are limited to a specific chain width and cannot securely hold chains with widths greater or lesser than the predetermined size, making them ineffective for chains of different speeds.
Innovation Solution
A chain tool design featuring a main body with adjustable driving mechanisms and a stopper system that allows for selective retention and driving of pins through chain plates, accommodating chains of varying widths through movable components and magnetic connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the chain tool is designed for a predetermined chain width, then it can securely hold chains of that specific width, but it cannot hold chains with widths greater or smaller than the predetermined width
Solution Approach 1:
The chain tool employs movable body portions that can adjust their positions relative to each other. The first and second body portions are connected through a movable connection mechanism, allowing the distance between them to be adjusted according to different chain widths. This dynamic adjustment capability enables the tool to securely retain chains of various widths while maintaining reliable operation.
Solution Approach 2:
The invention changes the geometric parameter of the tool's working distance between the first and second body portions. By adjusting this distance parameter to match different chain widths, the tool can adapt to various chain sizes. The movable connection mechanism enables this parameter change while maintaining secure retention through adjustable clamping force.
2Adaptability or versatility
If the chain tool uses a fixed driving mechanism, then it can maintain structural simplicity, but it cannot accommodate chains of varying widths
Solution Approach 1:
The driving mechanism incorporates movable body portions that can adjust their positions. The first and second body portions are connected through a movable connection mechanism, allowing the distance between them to be adjusted according to different chain widths. This dynamic adjustment capability enables the tool to securely retain chains of various widths while maintaining reliable operation.
Solution Approach 2:
The chain tool is designed with universal applicability through its adjustable structure. The movable connection mechanism between the first and second body portions allows the same tool to handle multiple chain widths, making it a multi-functional device that replaces the need for multiple fixed-width chain tools.
3Adaptability or versatility
If the chain tool uses a movable driving mechanism, then it can accommodate chains of varying widths, but it increases device complexity
Solution Approach 1:
The chain tool is divided into distinct segments: a first body portion and a second body portion that can move relative to each other. This segmentation allows independent adjustment of each portion's position, enabling adaptability to different chain widths while keeping each segment's structure relatively simple and manageable.
Solution Approach 2:
The chain tool employs movable body portions that can adjust their positions relative to each other. The first and second body portions are connected through a movable connection mechanism, allowing the distance between them to be adjusted according to different chain widths. This dynamic adjustment capability enables the tool to securely retain chains of various widths while maintaining reliable operation.

AI summary
A chain tool with a main body having a first body portion and a second body portion. A driving mechanism is supported by the first body portion and movable toward and away from the second body portion. The driving mechanism includes a first driving member adapted to retain one of a pair of plates of a chain and a second driving member adapted to drive a pin through the pair of plates. A stopper adapted to stop the pin selectively connected with the second body portion between a first and a second connection way. The second body portion has a slot for connecting the stopper. In the first connection way, the stopper includes a first end inserted in the slot. In the second connection way the stopper includes a second end inserted in the slot.
