Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the gate valve uses fixed sealing strength design, then the sealing performance is stable, but the adaptability to different specifications and sizes is poor
Solution Approach 1:
The patent applies the dynamics principle by making the sealing force adjustable through the elastic member. The elastic member can be replaced with different elastic coefficients to adapt to different valve specifications and sizes, transforming a fixed sealing system into a dynamic, adjustable one. This resolves the contradiction by enabling the same valve structure to adapt to various applications while maintaining reliable sealing through appropriate elastic member selection.
Solution Approach 2:
The patent implements parameter changes by allowing modification of the elastic coefficient of the elastic member based on different application requirements. By changing this key parameter, the valve can adapt to different specifications and sizes without altering the basic structure, thus improving adaptability while maintaining sealing reliability through parameter optimization.
2Ease of operation
If the gate valve uses complex components to achieve smooth movement, then the movement smoothness is improved, but the manufacturing cost increases
Solution Approach 1:
The patent applies the extraction principle by removing unnecessary complex components from the gate valve structure. Instead of using multiple complex mechanisms to achieve smooth movement, the invention extracts only the essential elements (elastic member, gate plate, transmission base) needed to accomplish the function, thereby simplifying the structure and reducing manufacturing cost while maintaining movement smoothness.
Solution Approach 2:
The patent implements self-service by designing the gate plate to automatically return to its initial position through the elastic force of the elastic member after being pushed by external force. This self-returning mechanism eliminates the need for additional complex components like springs or actuators, achieving smooth bidirectional movement with a simplified structure that is easier and less costly to manufacture.
3Adaptability or versatility
If the gate valve uses multiple elastic members with different elastic coefficients, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent applies the universality principle by designing a standardized elastic member component that can serve multiple functions and adapt to different valve specifications. Instead of creating entirely different structures for each application, the same elastic member design with adjustable elastic coefficients can be universally applied across different valve sizes and types, improving adaptability without increasing structural complexity.

AI summary
A gate valve (10) includes a valve body (20), a transmission base (42) disposed in the valve body (20), and two gate plates (56) disposed at two sides of the transmission base (42). The gate plates (56) are connected together through an elastic member (68a, 68b, 68c, 80) disposed in the transmission base (42). When the transmission base (42) is located at a first position (PI), the gate plates (56) are received in a chamber (23) and moved towards each other by the elastic member (68a, 68b, 68c, 80) to open valve openings (24). When the transmission base (42) is located at a second position (P2), the valve openings (24) are sealed by the gate plates (56), and an elastic positioning portion (72, 84) of the elastic member (68a, 68b, 68c, 80) is abutted against a positioning plate (29) of the valve body (20) for providing a buffer positioning effect to the gate plates (56). Therefore, the gate valve (10) of the present invention is opened and closed by using the elastic member (68a, 68b, 68c, 80), and has advantages of smooth movement, simple structure, and good adaptability.
