Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible air bag structure is used in the pneumatic driving device, then the device can be compact and adaptable, but the structure becomes complex and the restoration speed becomes slow
Solution Approach 1:
The patent replaces the flexible air bag mechanical system with a rigid piston-cylinder mechanism. The piston slides within the cylinder barrel under air pressure, converting the flexible membrane-based force transmission into a rigid rod-based mechanical system. This substitution eliminates the need for complex flexible structures while maintaining adaptability through the sliding piston mechanism.
Solution Approach 2:
The patent extracts and removes the flexible air bag component from the system, replacing it with a rigid piston structure. By taking out the problematic flexible element that caused structural complexity and slow restoration, the invention achieves a simpler, faster-restoring mechanism while preserving the pneumatic actuation function through the air cavity pressing on the piston.
2Volume of moving object
If a flexible air bag structure is used in the pneumatic driving device, then the device can be compact, but the restoration speed becomes slow
Solution Approach 1:
The patent substitutes the slow-restoring flexible air bag with a rigid piston-cylinder mechanism where air pressure directly acts on the piston face. The rigid structure allows for faster force transmission and quicker restoration when air pressure is released, as the piston can rapidly return to its initial position without the slow deflation and membrane relaxation inherent in flexible air bags.
Solution Approach 2:
The patent creates a simplified rigid copy of the pneumatic actuation function. Instead of using the complex flexible air bag that slowly restores, it replicates the essential function of pneumatic force transmission through a rigid piston system that can rapidly respond to pressure changes, achieving faster restoration speed while maintaining compact dimensions.
3Stability of the object's composition
If a rigid structure is used to replace the flexible air bag, then the structural stability is improved, but the flexibility and adaptability may be reduced
Solution Approach 1:
The patent replaces the flexible air bag with a rigid piston-cylinder mechanism that maintains structural stability through precise mechanical geometry. The rigid components provide stable force transmission, while the sliding piston mechanism within the cylinder barrel provides the necessary movement and adaptation capability, thus maintaining versatility without sacrificing stability.
Solution Approach 2:
The patent introduces dynamic capability to the rigid structure through the sliding piston mechanism. The piston can move freely within the cylinder barrel, providing adaptability and flexibility to the otherwise rigid system. This dynamic element allows the rigid structure to adjust to different positions and maintain versatility while preserving structural stability through the rigid cylinder and piston components.
