Shock Absorber Strut Lifting Tool with Sliding and Pivoting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for lifting shock absorber struts on motor vehicles are difficult to place on certain vehicles due to bulk mechanical and bodywork parts, and they offer limited security during use.
Innovation Solution
A tool with a first part extending along a vertical Z axis and a second part extending along a transverse X axis, capable of sliding, which can grip the strut and connect to a lifting device, featuring a jaw for secure clamping and blocking mechanisms to ensure stability and adaptability to different vehicle configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional bracket tool is used for lifting struts, then the structure is simple, but the tool cannot adapt to different vehicle configurations and offers limited safety
Solution Approach 1:
The tool is divided into three distinct parts: a first part extending along a vertical Z axis for lifting, a second part extending along a transverse X axis for positioning, and a third part with a distal end for gripping the strut. This segmentation allows each part to perform its specific function independently, enabling adaptation to different vehicle configurations while maintaining manageable structural complexity.
Solution Approach 2:
The second part is mounted to slide along the X axis relative to the first part, and the third part is mounted to pivot about a Y axis relative to the second part. These dynamic mounting arrangements allow the tool to adjust its configuration dynamically to fit different vehicle types and strut positions, resolving the contradiction between adaptability and structural simplicity.
2Reliability
If a traditional lifting tool is used, then the installation is straightforward, but the tool offers little safety during use
Solution Approach 1:
The distal end of the third part is designed with specific gripping characteristics tailored to the strut, with capability to grip struts with diameters between 10 mm and 100 mm. This localized specialization at the gripping end provides enhanced safety and reliability without significantly complicating the overall installation process.
Solution Approach 2:
The third part is mounted to pivot about a Y axis relative to the second part, allowing dynamic adjustment of the gripping angle and position. This dynamic capability ensures secure grip on the strut during lifting operations, enhancing safety while maintaining reasonable ease of operation through the articulated design.
3Adaptability or versatility
If a rigid fixed-structure tool is used, then the manufacturing is simple, but the tool cannot adapt to struts of different diameters
Solution Approach 1:
The gripping function is isolated to the third part, which can be manufactured with specific dimensional characteristics for gripping struts of various diameters. This segmentation allows the gripping component to be optimized for adaptability while the other parts maintain simpler manufacturing requirements.
Solution Approach 2:
The tool is designed to accommodate struts with diameters ranging from 10 mm to 100 mm through the dimensional characteristics of the third part. This parameter-based design approach allows a single tool structure to handle multiple strut sizes without requiring complex adjustable mechanisms, balancing manufacturability with adaptability.
