Balanced Vertical Moving Apparatus for Vehicle Wheels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting devices for vehicle wheels require excessive compressed air, complex operation procedures, and struggle with maintaining pressure balance during lifting and lowering, especially when handling large and heavy wheels, leading to inefficiencies and potential errors.
Innovation Solution
A balanced vertical moving apparatus with a fluid-dynamic actuator system that includes detection means to adjust air supply based on weight, allowing precise elevation control and efficient lifting/lowering operations, and can move away from the lifted body to support it on another device, optimizing air usage and simplifying operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a fluid-dynamic actuator with additional accumulator is used to lift heavy wheels, then the lifting capability is improved, but the air consumption increases excessively
Solution Approach 1:
The patent introduces a counterbalancing mechanism where a counterweight element is added to offset the weight of the wheel being lifted. This reduces the net force required from the fluid-dynamic actuator, thereby significantly decreasing the air consumption while maintaining the ability to lift heavy wheels. The counterweight creates a balanced system where the actuator only needs to provide force for the difference between the wheel weight and counterweight.
Solution Approach 2:
The patent employs dynamic adjustment of the actuator's operation based on the actual weight being lifted. The system continuously monitors the lifting conditions and adjusts the air supply, piston movement, and actuator force accordingly. This dynamic control prevents excessive air consumption by matching the actuator output to the actual load requirements rather than operating at constant high power.
2Stability of the object's composition
If complex air management procedures are implemented to maintain pressure balance, then the pressure stability is improved, but the operation complexity increases
Solution Approach 1:
The patent implements a self-regulating pressure balance system that automatically maintains pressure stability without requiring complex manual air management procedures. The system includes sensors and control mechanisms that continuously monitor pressure conditions and automatically adjust air supply, accumulator discharge, and actuator operation to maintain optimal pressure balance. This self-service approach eliminates the need for operators to perform complex manual adjustments while ensuring consistent pressure stability throughout the lifting and lowering cycles.
3Force
If the platform is designed to support heavy wheels at elevated positions, then the lifting capability is improved, but the device complexity increases
Solution Approach 1:
The patent applies the equipotentiality principle by designing the platform support system to distribute and balance the heavy load through multiple support points and structural elements. The frame structure, scissor-like mechanism, and platform supports are configured to create a balanced load distribution system that reduces stress on individual components. This approach enables the device to support heavy wheels at elevated positions without requiring overly complex structural reinforcements, as the load is evenly distributed throughout the system.

AI summary
A balanced vertical moving apparatus for moving a body having a first weight toward, or from a selected elevation comprises: loading means on which the body is designed to be loaded; moving means powered by a power source; first detection means for detecting the first weight, which are interposed between the loading means and the moving means; storage means for storing a reference weight in a storage device; drive means for driving the moving means, which are connected to said first detection means and said storage means and are designed to actuate said moving means, the drive means comprising at least two alternately selectable operating states, a first lifted state and a second lowered state, which are both designed to be selected by external control means, a third automatic actuation state being selectable when an additional external force is applied to said loading means.
