Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If pneumatic cylinders with high pressure are used for lifting, then lifting power is sufficient, but safety deteriorates due to risk of bursts and uncontrolled activation
Solution Approach 1:
The patent replaces the pneumatic system with an electric motor system. Instead of using compressed air at 30-40 bar that risks bursting and uncontrolled activation, the invention uses electric motors with controlled power output to drive the jack elements, eliminating the safety hazards while maintaining sufficient lifting capability through electrical control
Solution Approach 2:
The patent explicitly abandons the pneumatic approach (cylinders with pipes, hoses, valves) in favor of an electric drive system. The technical problem statement identifies pneumatic systems as dangerous, and the solution implements electric motors that provide controlled force without the risks of pressurized gas systems
2Ease of manufacture
If pneumatic systems with pipes, hoses and valves are used, then lifting function is achieved, but device complexity increases and safety deteriorates
Solution Approach 1:
The patent extracts and removes the complex pneumatic components (pipes, hoses, valves, connection nozzles) from the system. By eliminating these elements and replacing them with a simplified electric motor and drive mechanism, the invention reduces device complexity while maintaining the lifting function and improving safety
Solution Approach 2:
The invention substitutes the entire pneumatic subsystem with an electric drive system. Instead of managing complex networks of pressurized fluid components, the patent uses electric motors that directly drive the jack elements, significantly simplifying the overall system architecture
3Power
If pneumatic cylinders are used for lifting, then lifting capability is achieved, but weight of the vehicle increases
Solution Approach 1:
The patent replaces heavy pneumatic cylinders and associated high-pressure equipment with lighter electric motor systems. The electric drive units provide sufficient lifting power for racing vehicles while significantly reducing the overall weight compared to pneumatic systems requiring robust pressure vessels and fluid infrastructure
4Productivity
If conventional pneumatic systems are used, then lifting function is achieved, but safety deteriorates due to high pressure risks
Solution Approach 1:
The patent eliminates the harmful high-pressure pneumatic system and replaces it with a safe electric drive system. The electric motors provide controlled lifting power without the risks of pressurized gas bursts, uncontrolled activation, or equipment failure associated with pneumatic systems
Solution Approach 2:
The electric jack elements are permanently mounted on the vehicle and can be activated independently without requiring external pneumatic infrastructure. This self-contained system eliminates the need for external high-pressure air supplies and complex connection systems, reducing safety risks
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 electrically operated jack system improves safety by eliminating the risks associated with pressurized gases, allowing for controlled and reliable lifting of vehicles, reducing the weight and complexity of the jack elements, and enabling easier interaction during pit stops.
Implementation Method 1
The jacking elements are designed to be electrically operated... the energy required for at least partially lifting the motor vehicle is therefore made available electrically to the jack element
