Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bayonet lock or rotary lock is used for coupling, then the connection can be made securely, but rotational movements directly entail the risk of decoupling or loosening
Solution Approach 1:
The coupling mechanism is divided into two independent functions: axial locking (preventing decoupling) and rotational freedom (allowing orientation adjustment). The spring-loaded coupling elements handle axial retention while the coupling interface permits free rotation, separating the locking function from the rotational function to eliminate the conflict between security and operational flexibility.
Solution Approach 2:
The coupling system transitions from a static locked position to a dynamic state where rotation is permitted during use. The spring-loaded coupling elements maintain axial connection security while allowing dynamic rotational movement, enabling the outlet body to be oriented in any direction without risking decoupling.
2Ease of manufacture
If a traditional coupling system is used, then assembly can be performed, but it requires tools and cannot be done when there is water pressure
Solution Approach 1:
The spring-loaded coupling elements automatically engage and lock the first and second coupling parts together through their own elastic force, eliminating the need for external tools. The self-actuating mechanism allows assembly and disassembly to be performed by simply moving the coupling parts along the coupling axis, even in the presence of water pressure.
Solution Approach 2:
The traditional mechanical tool-based coupling system is replaced with a spring-loaded self-actuating mechanism. The elastic force of the spring elements substitutes for manual tool operation, enabling tool-free assembly and disassembly while maintaining secure connection under various operating conditions including water pressure.
3Reliability
If the coupling is designed to be secure against decoupling, then connection reliability is improved, but cleaning and maintenance become more difficult
Solution Approach 1:
The coupling system allows easy disassembly for cleaning and maintenance by simply moving the coupling parts axially to release the spring-loaded locking elements. After maintenance, the parts are easily reassembled by moving them together along the coupling axis, where the spring elements automatically engage to restore secure connection. This dynamic design provides both security during operation and accessibility during maintenance.

AI summary
A water outlet assembly comprises a quick-release coupling device (200) with a first coupling part (210) and a second coupling part (220), which can be detachably connected to each other by means of a spring-loaded coupling (241, 242). To couple the coupling, the two coupling parts (210, 220) are moved relative to each other along a coupling axis until the spring-loaded coupling (241, 242) engages. When coupled, the two coupling parts (210, 220) are freely rotatable relative to each other. The first coupling part (210) has a flow channel (214) with a valve (230) that is open when the two coupling parts (210, 220) are coupled and closed when the two coupling parts (210, 220) are uncoupled. A discharge body (290) is connected to the second coupling part (220).The coupling components (210, 220) can be equipped with an electronic interface (250, 250a, 350, 350a) for signal transmission. The quick-release coupling can be used for a hand shower, connecting a tap with a mixing device upstream of the quick-release coupling, etc.
