Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire lifting devices face inefficiencies due to difficulties in achieving optimal fluid pressure for lifting, often resulting in excessive pressure usage, and this issue extends to other applications requiring controlled fluid pressure for container filling.
Innovation Solution
A device with a pressure adjusting mechanism and locking/unlocking means that allows for precise control of fluid pressure, ensuring correct pressure is maintained for efficient operation, particularly in tire lifting applications, by using a pressure adjuster and control valve to set and maintain the desired outlet pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cam mechanism is used to lift the wheel, then the lifting function is achieved, but the structure becomes complex and operation becomes difficult
Solution Approach 1:
The patent removes the cam mechanism from the lifting device, extracting the complex sliding engagement component that caused operational difficulties. The lifting function is achieved through a simpler direct actuation mechanism where the actuator stem directly moves the cross-frame and lifting plane without requiring a cam profile.
Solution Approach 2:
Instead of using a cam to convert rotational motion into lifting motion, the patent inverts the approach by using a direct linear actuation system where the actuator stem directly produces the lifting motion, eliminating the need for complex cam-follower engagement.
2Force
If air pressure is increased to lift heavier wheels, then lifting capability is improved, but energy consumption increases and excessive pressure is wasted
Solution Approach 1:
The patent adjusts the air pressure parameter dynamically to match the actual lifting requirements. By controlling the pressure to the minimum necessary value for each specific wheel weight and size, the system avoids energy waste from excessive pressure while maintaining adequate lifting capability across different wheel types.
Solution Approach 2:
Instead of always applying maximum or excessive air pressure, the system uses partial action by supplying only the necessary amount of pressure required for each specific lifting task, thereby reducing energy consumption while maintaining effective lifting performance.
3Speed
If a cam mechanism with sliding engagement is used, then lifting motion is achieved, but operational efficiency decreases
Solution Approach 1:
The patent removes the cam-follower sliding engagement mechanism that reduced operational efficiency. The direct actuation system eliminates the friction and mechanical losses associated with sliding contact, resulting in faster and more efficient lifting operations.

Implementation Method 1
a pressure adjuster (5), for example a pressure reducer, which intercepts the supplying line (3) and is intended to receive in input the fluid at an inlet pressure and to supply it at a controlled outlet pressure
Implementation Method 2
at least one valve member (4) of the supplying line (3), which intercepts the supplying line (3) and is movable between a closing position in which it obstructs the fluid supplying and one or more opening positions in which it allows fluid supplying
