Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices for hoist or traction tools in automotive workshops are cumbersome to move due to their heavy bases, and reducing weight compromises the maximum traction force, limiting their working capacity.
Innovation Solution
A portable support device with a base that uses a flexible perimeter rim and vacuum generating means to create a sealed space, allowing rigid fastening to the support surface, enabling easy relocation and maintaining high traction force capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If heavy elements are used in the base to keep the support device immobile, then the support stability is improved, but the ease of moving the device deteriorates
Solution Approach 1:
The base transitions from a static heavy structure to a dynamic system that can change its mobility state. The vacuum generation means activates to create negative pressure that firmly attaches the base to the floor during operation, then deactivates to allow easy movement. This dynamic switching between fixed and movable states resolves the contradiction between stability and ease of moving.
Solution Approach 2:
The invention uses vacuum (pneumatic principle) to create a firm connection between the base and the support surface. The vacuum generation means creates negative pressure that holds the base firmly in place during use, providing stability without requiring heavy elements. When the vacuum is released, the base can be easily moved, thus resolving the contradiction between stability and mobility.
2Ease of operation
If the weight of base elements is reduced to make moving easier, then the ease of moving is improved, but the maximum traction force deteriorates
Solution Approach 1:
The vacuum system creates a firm connection between the base and floor, allowing the base to remain stationary during high-force traction operations. This pneumatic anchoring enables the use of lighter base materials while still supporting maximum traction forces up to 2500 Kg, as the vacuum pressure compensates for the reduced weight.
Solution Approach 2:
The vacuum pressure acts as a counterbalancing force that prevents the lightweight base from moving during traction operations. The negative pressure creates a holding force that counteracts the traction forces applied to the hoist tool, allowing lightweight construction without compromising the maximum traction force capability.
3Ease of operation
If a vacuum system is used to secure the base, then the ease of moving is improved, but the device complexity increases
Solution Approach 1:
The base integrates multiple functions: it serves as the structural platform for the column and hoist tool, provides the sealing surface for vacuum attachment, and houses the vacuum generation means. This multi-functionality reduces overall device complexity by combining what could be separate components into a unified base structure.
Solution Approach 2:
The vacuum generation means is integrated directly into the base structure rather than being a separate movable component. The sealing rim is incorporated as part of the base perimeter. This merging of components simplifies the overall device architecture while maintaining the ease of moving benefit provided by the vacuum system.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy movement and location of the support device while maintaining a maximum traction force of 2500 Kg, suitable for automotive repair tasks, by using vacuum-generated negative pressure for secure fastening and flexible pulley systems for directional adjustment.
Implementation Method 1
a vacuum generating means in fluid communication with the closed space formed, by means of a vacuum line or pipe that is connected to a perforation in the base, such that a vacuum or negative pressure generated by the vacuum generating means creates such a depression or reduction of pressure inside the closed space that it produces a rigid fastening of the base to the support surface
