Pivoting Hook Tool for Flexible Axle-Ring Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for detaching annular elements from axles lack flexibility in hook direction, necessitating separate tools for different types of annular elements like gears and pulleys.
Innovation Solution
A multi-angular tool with a sliding element, pivotal elements, and hooking elements that allow hooks to pivot to different angles, enabling engagement with both internal and external portions of annular elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hooks are formed with barbs extending from an end in a fixed sense of direction, then the tool structure is simple, but the tool cannot effectively engage with different types of annular elements (gears, pulleys) requiring different barb directions
Solution Approach 1:
The hooking elements are made pivotal relative to the sliding element, allowing them to rotate and adjust their orientation. This dynamic capability enables the same tool to effectively engage with different types of annular elements (gears, pulleys) by positioning barbs in the required directions, thereby improving adaptability without requiring multiple separate tools.
Solution Approach 2:
The tool is designed with multiple hooking elements that can be positioned at different angles through pivotal movement. This universal design allows a single tool to perform multiple functions by engaging with various annular elements requiring different barb orientations, eliminating the need for separate specialized tools for each element type.
2Reliability
If separate tools are used for different types of annular elements, then each tool can be optimized for its specific function, but the quantity of tools required increases
Solution Approach 1:
The tool integrates multiple hooking elements with adjustable orientations, enabling a single tool to replace multiple specialized tools. Each hooking element can be positioned to engage with specific annular element types, maintaining reliable engagement effectiveness while reducing the total number of tools required from multiple specialized instruments to one multi-functional tool.

AI summary
A multi-angular tool for detaching an annular element from an axle includes a rod, a sliding element, multiple hooking elements and multiple pivotal elements. The sliding element is movably connected to the rod. Each of the pivotal elements includes a first end pivotally connected to the sliding element about a first axis and a second end pivotally connected to a corresponding one of the hooking elements about a second axis.
