Lifting Jack Support with Flexible Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lifting jacks risk damaging vehicle components, especially those with delicate parts, due to their rigid construction, which is inadequate for handling components requiring protection from shocks and vibrations.
Innovation Solution
A lifting jack with a telescopic body and a support system comprising a rigid part with hooks and a flexible, deformable part, allowing the support to be positioned in two ways: one for robust components and another for delicate ones, with the flexible part absorbing shocks and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid metal support is used in the lifting jack, then the strength and stability of the support is improved, but the risk of damaging delicate vehicle components increases
Solution Approach 1:
The support is divided into two separate parts: a rigid support element for structural strength and a flexible protective element for damage prevention. These segments can be independently positioned to serve different functions, resolving the contradiction between strength and protection.
Solution Approach 2:
Different parts of the support system have different mechanical properties - the support element is rigid for strength, while the protective element is flexible for protection. This local differentiation allows each part to perform its specific function optimally without compromising the other.
2Device complexity
If a single rigid support structure is used, then the device complexity is reduced, but the adaptability to handle different component types is worsened
Solution Approach 1:
The support system is made dynamically reconfigurable through a telescopic mechanism that allows the support element to be positioned in different locations. This dynamic adjustment capability provides versatility for handling different component types while maintaining relatively simple individual components.
Solution Approach 2:
The lifting jack is designed with multi-functionality by incorporating both rigid and flexible support elements that can be configured for different handling scenarios. The same basic structure serves multiple purposes: supporting robust components with the rigid element and protecting delicate components with the flexible element.
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
The lifting jack effectively handles both robust and delicate components without causing damage, offering dual functionality and enhanced stability, making it more versatile and practical for various handling tasks.
Implementation Method 1
the flexible part is formed by a deformable material... the flexible part comprises a second hole... the first hole is a through hole comprising, at least, one change in diameter to retain the support in two different positions
