Innovation Solution
A multi-stage positioning structure incorporating a combined first snapper, a flexible member, and an adjustable screw bolt spacer, allowing for flexible operation and adjustable resistance to meet different user needs, enhancing durability and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If projecting points are directly preformed on the brake valve handle, then the multi-stage positioning structure can be achieved, but the projecting points will wear, deform and thin leading to reduced service life
Solution Approach 1:
A positioning pin is introduced as an intermediary component between the brake valve handle and the valve core. The positioning pin is rotatably connected to the valve core and engages with positioning grooves on the handle, transferring the positioning function from the handle's projecting points to a dedicated pin mechanism. This mediator bears the wear and stress, protecting the handle's projecting points from degradation.
Solution Approach 2:
The positioning structure is segmented into distinct functional components: the positioning pin, the flexible member, and the positioning grooves. This segmentation allows each component to be optimized for its specific function - the pin for engagement, the flexible member for providing resilient force, and the grooves for positioning - thereby improving overall reliability and service life.
2Device complexity
If a fixed positioning structure is used, then the structure is simple, but it cannot accommodate varying operating forces and habits of customers in different markets
Solution Approach 1:
The positioning structure incorporates a flexible member (such as a spring) that provides resilient force to the positioning pin. This dynamic element allows the pin to flex and adapt to varying operating forces and user habits while maintaining reliable positioning. The system transitions from a rigid fixed structure to a dynamic adaptive structure that can accommodate different market requirements.
3Strength
If projecting points are tightly snapped into positioning grooves with fixed strength, then positioning is secure, but the structure cannot be adjusted for different user needs
Solution Approach 1:
The positioning system uses a flexible member whose elastic properties can be adjusted by changing parameters such as the spring constant, pre-compression force, or material properties. This allows the positioning locking strength to be customized for different user needs and market requirements while maintaining the secure engagement function.

AI summary
A ceramic valve core has a multi-stage positioning structure. The multi-stage positioning structure includes a first snapper, which can move along with the swaying motion of the brake valve handle of the ceramic valve core, and a second snapper, which is an integrated component positioned correspondingly to the displacement track of the said first snapper. At the corresponding ends of the first snapper and the second snapper, there is a snap ring mated with at least two pin joint ends. The positioning structure also includes a flexible member, which allows the first snapper or second snapper to operate flexibly. The multi-stage positioning structure of the present invention is sturdy because the first snapper is of a combined type and is flexible thanks to the flexible member.
