Adjustable Vehicle Part Puller for Multi-Geometry Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pulling tools for vehicle parts, such as pitman arms, struggle to securely engage parts of different sizes, shapes, and configurations, making it difficult to displace them relative to other components during maintenance and repair.
Innovation Solution
A part displacement tool with a frame, drive screw, and engaging arm assemblies that allow for adjustable engagement with parts of varying dimensions, enabling secure attachment and displacement through rotational mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid C-shaped frame with a drive screw is used to pull a pitman arm, then the drive force can be applied to displace the pitman arm relative to the drag link, but the frame cannot securely engage parts of different sizes, shapes, and configurations
Solution Approach 1:
The frame is divided into multiple segments including a body, an engaging arm assembly, and an engaging member that can move relative to the frame. This segmentation allows the engaging member to adjust its position and orientation to accommodate different part geometries while maintaining a relatively simple overall frame structure.
Solution Approach 2:
The engaging member is configured to move relative to the frame along a path that allows it to adapt to different part shapes and sizes. This dynamic adjustment capability enables the same frame structure to securely engage various configurations without requiring multiple specialized frames.
2Adaptability or versatility
If the engaging member is fixed relative to the frame, then the frame structure remains simple, but it cannot accommodate first parts of different sizes, shapes, and configurations
Solution Approach 1:
The engaging member is configured to move relative to the frame along a defined path, allowing it to adapt its position to accommodate different part geometries. This relative movement capability provides versatility without requiring a completely complex reconfigurable frame structure.
Solution Approach 2:
The engaging member acts as an intermediary between the fixed frame structure and the varying part geometries. It translates the fixed frame's positioning capability into adaptable engagement with different parts through its relative movement along the defined path.
3Adaptability or versatility
If a pulling tool is designed for specific part configurations, then it can provide reliable engagement for those parts, but it cannot be used for parts of different sizes and shapes
Solution Approach 1:
The engaging member's ability to move relative to the frame provides multi-configurability automatically during operation. The operator simply needs to position the tool near the target part, and the engaging member can adjust along its path to achieve proper engagement, reducing operational complexity despite increased versatility.
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
Facilitates secure and adaptable engagement of vehicle parts, allowing for efficient detachment and displacement relative to other components, accommodating diverse part sizes and configurations.
Implementation Method 1
a drive screw threaded through the frame. The frame is engaged with the first part, and the drive screw is rotated relative to the frame to apply a driving force to the second part to displace the pitman arm relative to the drag link
Implementation Method 2
The at least one engaging arm assembly is configured to be supported by the at least one arm opening and comprises an engaging member and an engaging screw. Operation of the engaging screw displaces the engaging member relative to the frame.
