Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional gate valve structures with multiple components are used, then sealing function is achieved, but device complexity increases and manufacturing cost rises
Solution Approach 1:
The patent merges multiple components into an integrated elastic member that combines sealing, positioning, and rebound functions. The elastic member integrates what were previously separate elements (sealing elements, positioning mechanisms, and rebound springs) into a single unified component, reducing overall device complexity while maintaining sealing reliability
Solution Approach 2:
The elastic member is designed as a multi-functional component that simultaneously provides sealing action, positioning of the gate plate, and rebound force generation. This universal component performs multiple functions that traditionally required separate parts, thereby simplifying the overall valve structure
2Ease of manufacture
If fixed sealing strength structures are used, then manufacturing is simplified, but adaptability to different specifications deteriorates
Solution Approach 1:
The patent introduces a dynamic adjustment mechanism that allows the sealing strength to be varied based on operational requirements. The elastic member's properties can be adjusted or selected to match different specifications and sizes, transforming a static sealing system into a dynamic one that adapts to different conditions
Solution Approach 2:
The patent enables changes in sealing parameters (such as elastic force, material properties, or geometric dimensions of the elastic member) to achieve different sealing strengths. By modifying these parameters, the same basic structure can be adapted to various specifications and sizes without requiring complete redesign
3Ease of operation
If complex transmission mechanisms are used, then gate plate control is achieved, but movement smoothness deteriorates
Solution Approach 1:
The elastic member serves itself by automatically providing both the control force for gate plate movement and the rebound force for returning to the initial position. The system uses the elastic deformation of the member itself to drive the transmission, eliminating the need for complex external transmission mechanisms
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 design achieves smooth gate plate movement, improved adaptability, and reduced manufacturing costs by allowing adjustable rebound force and simplified components, enhancing operational efficiency and flexibility.
Implementation Method 1
The gate plates are moved towards each other by an elastic force of the elastic member
Implementation Method 2
the elastic positioning portion of the elastic member is abutted against the positioning plate of the valve body for providing a buffer positioning effect to the gate plates

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