Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional faucet control valves have complex structures that make it difficult to accurately and easily connect the rotatable operation rod, leading to troublesome assembly and potential leakage issues.
Innovation Solution
A connection structure for a ceramic cartridge faucet comprising a control body, rotatable operation rod, connection ring, stop ring, guide ring, and seal washer, where the rotatable operation rod is securely connected using a C retainer and O rings, with a guide ring and stop ring design that facilitates easy alignment and prevents water leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional control valve structure is used, then the faucet can control water flow, but the connection between the rotatable operation rod and control body is complicated and troublesome
Solution Approach 1:
The control valve is divided into modular components: control body, rotatable operation rod, connection ring, stop ring, guide ring, and seal washer. Each component has a specific function and can be assembled independently, simplifying the overall connection process while maintaining functionality.
Solution Approach 2:
The connection ring acts as an intermediary component between the rotatable operation rod and the control body. It includes a receiving groove that receives the insertion of the operation rod, and a rib that connects with the stop ring, facilitating easy alignment and connection without complex structures.
2Manufacturing precision
If conventional control valve structures are used, then water flow control is achieved, but alignment between the rotatable operation rod and stop ring is difficult
Solution Approach 1:
The guide ring serves as a guiding intermediary that directs the rotatable operation rod into correct alignment with the stop ring during assembly. The guide ring's structure ensures proper positioning, making alignment precise and assembly easy simultaneously.
Solution Approach 2:
The connection structure enables self-alignment through the interaction between the insertion of the operation rod, the receiving groove of the connection ring, and the guide ring. The components guide themselves into proper alignment during the assembly process without requiring external alignment tools or complex procedures.
3Reliability
If conventional control valve structures are used, then water flow is controlled, but water leakage occurs
Solution Approach 1:
The seal washer, made of flexible rubber material, is used to prevent water leakage at the connection interfaces. The flexible nature of the rubber seal washer allows it to conform to the mating surfaces and maintain effective sealing under varying pressure conditions without adding significant structural complexity.
Solution Approach 2:
The connection ring with its rib structure acts as an intermediary that ensures proper positioning and sealing between the operation rod and control body. The rib connects with the stop ring and helps maintain the integrity of the sealing interface, preventing leakage while keeping the structure relatively simple.
4Productivity
If conventional control valve structures are used, then the faucet operates, but the connection process is troublesome and time-consuming
Solution Approach 1:
By segmenting the control valve into standardized components with clear interfaces (control body, operation rod, connection ring, stop ring, guide ring, seal washer), the assembly process becomes systematic and efficient. Each component can be prepared independently and assembled in a straightforward sequence, improving productivity.
Solution Approach 2:
The connection ring serves as a mediating component that simplifies the connection process between the operation rod and control body. Its receiving groove and rib structures guide the assembly process, making the connection straightforward and reducing assembly time while maintaining ease of operation.

AI summary
A connection structure of a ceramic cartridge of a faucet contains: a control body, a rotatable operation rod, a connection ring, a stop ring, a guide ring, and a seal washer. The control body includes an accommodation space and an outlet. The guiding ring includes a fan-shaped hole corresponding to multiple stopping fringes of the stop ring. The control body includes an orifice, and the rotatable operation rod includes multiple O rings fitted thereon to avoid a leakage of the waters. The orifice has a recess, and the rotatable operation rod includes a notch for accommodating a C retainer. The rotatable operation rod includes an insertion, and the connection ring includes a receiving trough. The insertion has a hook, and the receiving trough has a cutout configured to engage with the hook. The connection ring includes a rib. The stop ring includes an aperture and multiple stopping fringes.
