Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If pneumatic or hydrodynamic actuators are used to generate thrust forces for cold plastic deformation, then sufficient deformation force can be achieved, but the structural complexity increases and safety risks arise due to pressurized fluid circuits
Solution Approach 1:
The patent replaces pneumatic or hydrodynamic actuators with an electromechanical actuator that uses a ball screw mechanism. The electromechanical actuator converts rotational motion from an electric motor into linear thrust motion through the ball screw, eliminating the need for pressurized fluid circuits while maintaining sufficient deformation force capability.
2Force
If pneumatic or hydrodynamic actuators are used, then deformation force is sufficient, but maintenance requirements increase and operational costs rise
Solution Approach 1:
The electromechanical actuator with ball screw replaces complex pneumatic or hydrodynamic systems that require frequent maintenance of pressurized fluid circuits, seals, and control valves. The electromechanical system has fewer moving parts subject to wear and contamination, significantly reducing maintenance requirements.
3Force
If pressurized fluid circuits are implemented, then adequate thrust force can be generated, but safety standards and operational costs increase
Solution Approach 1:
The patent eliminates pressurized fluid circuits by using an electromechanical actuator system. This substitution removes safety risks associated with high-pressure fluids, eliminating the need for specialized safety standards, continuous monitoring systems, and expensive safety compliance measures while maintaining adequate thrust force generation.
