Chain Tool With Arcuate Pressing Member for Quick Link Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chain tools are not suitable for quick release chain fasteners with arcuate elongated slots, as they are designed for rectilinear slots only, leading to inefficient operation.
Innovation Solution
A chain tool with a body, push unit, and elastic elements that allow the pressing member to move in an arcuate path, enabling smooth operation on quick release chain fasteners with arcuate slots by using a rocker arm or sliding seat mechanism to engage and release the chain links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional chain tool with linear movement mechanism is used on a quick release chain fastener with arcuate elongated slot, then the device structure is simple, but the operation is not smooth and cannot be used effectively
Solution Approach 1:
The pressing member is designed to move along an arcuate path instead of a linear path, matching the arcuate shape of the elongated slot in the chain link plate. This curved movement path enables smooth engagement and disengagement of the quick release chain fastener, resolving the incompatibility between conventional linear tools and arcuate slots.
Solution Approach 2:
The chain tool is designed with a universal pressing member that can accommodate both rectilinear and arcuate elongated slots. The pressing member's arcuate path capability allows the same tool to effectively operate on different types of quick release chain fasteners, enhancing versatility while maintaining ease of operation.
2Reliability
If the pressing member moves in a linear path, then the device structure is simple, but it cannot engage properly with arcuate elongated slots
Solution Approach 1:
The pressing member follows an arcuate movement path that precisely matches the geometry of the elongated slot. This curved path ensures proper engagement with arcuate slots, preventing slippage or improper seating that would occur with linear movement, thereby enhancing reliability of the connection.
Solution Approach 2:
The pressing member acts as an intermediary between the push member and the chain link plate. By incorporating the arcuate path mechanism, it mediates the force transmission in a way that accommodates the geometric requirements of the slot, ensuring reliable engagement without requiring the entire device to be complex.
3Adaptability or versatility
If a chain tool is designed for rectilinear slots only, then the manufacturing is simple, but the adaptability to different slot types is limited
Solution Approach 1:
The chain tool incorporates a pressing member capable of arcuate movement that can effectively engage with both rectilinear and arcuate elongated slots. This universal design allows a single tool to serve multiple purposes, accommodating different slot geometries without requiring separate specialized tools for each type.
Solution Approach 2:
The pressing member is designed with dynamic movement capability along an arcuate path, allowing it to adapt its movement trajectory to match different slot geometries. This dynamic characteristic enables the tool to handle various slot types, enhancing adaptability while maintaining a relatively simple overall device structure.
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
Enables rapid detachment of quick coupling chain links with arcuate elongated slots from their pins, providing a smooth and efficient operation similar to conventional tools designed for rectilinear slots.
Implementation Method 1
An elastic element is received in the groove and includes a first end attached to the back board and a second end abutting against a side of the pressing member opposite to the push member

AI summary
A chain tool includes a body having a driving hole, a stop portion, and a receiving portion located between the driving hole and the stop portion in an axial direction. A pressing member is received in the receiving portion and is movable relative to the body in the axial direction. A push member is in threading connection with the first threaded portion and is movable relative to the body between a first position distant to the stop portion and a second position adjacent to the stop portion. The pressing member is pressed by the push member and moves in an arcuate path when the push member moves between the first and second positions.
