Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sleeve thread fixation method is used, then fixation stability is improved, but installation complexity increases due to narrow installation space and requirement for specialized tools
Solution Approach 1:
The locking mechanism is divided into multiple locking blocks (at least two) spaced apart along the circumferential direction of the mounting hole. Each locking block can be independently actuated by transmission members, allowing distributed locking force application that simplifies installation while maintaining overall fixation stability.
Solution Approach 2:
The locking blocks are equipped with elastic assemblies that enable automatic radial movement in response to applied force. When transmission members push the first inclined surfaces, the locking blocks dynamically adjust their position radially inward to engage the faucet, and automatically rebound radially outward when force is released, enabling tool-free operation.
2Strength
If C-shaped copper nuts are used to ensure sufficient thread length and opening strength, then structural strength is improved, but device complexity and cost increase due to increased thickness and material cost
Solution Approach 1:
The single complex C-shaped copper nut is segmented into multiple simpler locking blocks that can be made from conventional plastic materials. Each locking block handles a portion of the locking function, collectively providing sufficient thread locking strength without requiring increased thickness or expensive copper material.
Solution Approach 2:
The patent replaces expensive copper nuts with conventional plastic materials for the locking blocks. This substitution significantly reduces material cost while maintaining functional performance through the distributed multi-block design that provides adequate strength without requiring thick-walled construction.
3Ease of manufacture
If fixed kind of nut is used for sleeve thread fixation, then manufacturing simplicity is improved, but adaptability decreases as the nut cannot be used for different thread sizes
Solution Approach 1:
The mounting hole in the base seat is designed with adjustable positioning members that can accommodate different thread specifications (e.g., M32*1.5, M33*1.5). The locking blocks work in conjunction with these adjustable positioning features to provide universal adaptability across different faucet thread sizes while maintaining simple manufacturing processes.
Solution Approach 2:
The adjustable positioning members allow the mounting structure to dynamically adapt to different thread configurations. This adjustability enables the same base seat and locking block assembly to serve multiple thread size requirements without requiring different nut designs, achieving versatility through configurable positioning rather than multiple specialized components.
4Reliability
If hexagon nuts of hot water inlet hose and cold water inlet hose are made to pass through lock nuts, then assembly completeness is improved, but installation difficulty increases due to space constraints and torque requirements
Solution Approach 1:
The locking function is segmented into multiple locking blocks that can be independently actuated. This segmentation allows the hexagon nuts of hot and cold water inlet hoses to be locked sequentially or simultaneously without requiring high torque, as each locking block handles a portion of the locking load, making installation feasible in narrow spaces under countertops.

AI summary
A quick assembly and quick disassembly device for a faucet, configured for fastening of the faucet, comprises a base seat, an upper cover, and at least two locking blocks. The base seat comprises a mounting hole. The upper cover is sleeved outside of the faucet and is detachably connected to the base seat. Each of the at least two locking blocks comprises a first inclined surface pushed by at least two transmission members to enable the at least two locking blocks to move radially inward to abut the faucet. A position-providing notch between two adjacent locking blocks provides a space for a joint of a flexible hose so as to easily mount or detach the faucet. A distal end of the at least two elastic assemblies is disposed in at least two locking blocks to enable the at least two locking blocks to move outward to release the faucet.
