Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting devices for vehicle wheel axles have complex and non-ergonomic assembly processes due to hidden tightening elements, making it difficult for users to access and assemble the components efficiently.
Innovation Solution
A lifting device with a single-piece connecting structure featuring lateral plates and an upper plate, where arms are coupled to the structure using a single bolt, allowing for easy assembly and preventing relative movement, and incorporating a stop element for pressure transmission to the suspension arm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple assembly screws are used to join the upper support halves, then the structural strength is improved, but the assembly complexity and difficulty of access increase
Solution Approach 1:
The patent merges multiple assembly screws into a single assembly screw that passes through both halves of the upper support. This single screw simultaneously performs the function of joining multiple components, reducing assembly complexity while maintaining structural strength through the unified fastening mechanism.
Solution Approach 2:
The single assembly screw serves multiple functions: it acts as both a fastening element and a alignment reference, and its position is designed to be easily accessible for assembly operations. This multi-functional design simplifies the assembly process while ensuring proper structural connection.
2Stability of the object's composition
If assembly screws are placed on the inside of the lifting support, then the structural integrity is improved, but the accessibility for assembly operations deteriorates
Solution Approach 1:
Instead of placing assembly screws on the inside of the lifting support as in prior art, the patent inverts the approach by positioning the assembly screw on the outside, where it is easily accessible. The screw passes through both halves of the upper support from the external side, making assembly operations simple while maintaining structural integrity through proper fastening.
3Adaptability or versatility
If a multi-component connecting structure is used, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple components (lower plate, lateral plates, upper plate) into a single integrated connecting structure made as one piece. This unification reduces device complexity by eliminating the need to assemble multiple separate components, while the design maintains adaptability through the geometric configuration of the integrated structure that allows articulation with the arms.
