Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If valve devices are custom-made for specific applications, then they can be optimized for particular uses, but they lack versatility and require separate designs for different applications
Solution Approach 1:
The valve device is designed with a universal structure that can be applied across multiple applications including firearms, pipelines, and industrial fluid systems. The closing mechanism with stop discs and activation bolts provides a standardized solution that works for gases, liquids, and fluids, eliminating the need for custom-designed valves for each application while maintaining optimal performance through pressure-activated operation
2Speed
If external manipulation is required for opening or closing the valve, then the valve can be precisely controlled, but it lacks rapid response capability and requires additional control systems
Solution Approach 1:
The valve employs a self-activating closing mechanism where pressure differences automatically trigger the stop discs to move and seal the flow path. The activation bolts respond to pressure buildup without requiring external sensors, actuators, or control systems, enabling rapid closure while eliminating the need for external manipulation infrastructure
Solution Approach 2:
The invention replaces complex electronic sensor-actuator systems with a purely mechanical pressure-activation mechanism. The stop discs and activation bolts directly respond to pressure differences through mechanical force, eliminating the need for electronic control systems while achieving faster and more reliable closure
3Productivity
If sensor means and actuators are added for adjustable valve operation, then flow control capability is improved, but device complexity and cost increase
Solution Approach 1:
The valve utilizes pneumatic principles where pressure differences in the fluid system directly activate the closing mechanism through the activation bolts. This pressure-activated system provides flow control capability without requiring external sensors or actuators, maintaining simplicity while enabling adjustable operation through the natural pressure dynamics of the fluid being controlled

AI summary
Valve device (10) based on a closing disc formed by disc parts (22a-c) which are movably arranged on activation bolts (16a-c) extending between two stop discs (14a-b), and where movement of the activation bolts (16a-c) or disc parts (22a-c) in longitudinal direction of the valve device (10) results in that the relative position between the disc parts (22a-c) are changed and the valve device (22a-c) opens or closes.
