Solution Overview
Problem
Conventional pull-out faucets face issues with water leakage and magnetic field interference due to the need for cutting the water outlet pipe to install magnetic starting mechanisms, which also affect the operation of other electronic components.
Innovation Solution
A switch detection assembly that includes a sleeve sliding pair, an elastic reset element, a diameter expanding element, and an accepting element, allowing for switch detection on a pull-out movement stroke without cutting the pipeline, using a combination of a fixing bracket, a movable sleeve, and various sensors to generate a switch signal for controlling water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a magnetic starting mechanism is mounted over the water outlet pipe to control water flow, then the signal control accuracy is improved, but the water outlet pipe needs to be cut and reconnected, causing water leakage risk and increased device complexity
Solution Approach 1:
The patent extracts the magnetic starting mechanism from the water outlet pipe by mounting it on a separate support structure positioned near the pipe. This allows the magnetic field to be generated at the required location without cutting or modifying the water pipe, thereby eliminating the water leakage risk while maintaining signal control accuracy.
Solution Approach 2:
The patent introduces a support structure as an intermediary component between the magnetic starting mechanism and the water outlet pipe. This mediator allows the magnetic mechanism to be positioned close to the pipe for accurate control without direct attachment to the pipe, thus avoiding the need to cut and reconnect the pipe.
2Measurement precision
If a strong magnetic field is used to ensure signal control accuracy during pull-out faucet operation, then the switch detection precision is improved, but the strong magnetic field interferes with other electronic control components such as infrared sensors
Solution Approach 1:
The patent applies local quality by using different types of sensors for different functions: a magnetic reed switch for detecting the pull-out stroke (requiring strong magnetic field) and an infrared sensor for other control functions (sensitive to magnetic interference). By spatially separating these sensor functions and using appropriate sensor types for each location, the patent achieves accurate switch detection without magnetic interference affecting other electronic components.
3Adaptability or versatility
If the water outlet pipe is cut and reconnected to mount the magnetic starting mechanism, then the signal control function is added, but the installation time and production cost increase
Solution Approach 1:
The patent extracts the magnetic starting mechanism from the water outlet pipe installation process by mounting it on a separate support structure. This eliminates the need to cut, insert, and reconnect the pipe, thereby significantly reducing installation time and production cost while still adding the desired signal control function.

Implementation Method 1
the elastic reset element generates an elastic restoring force against the movement of the movable sleeve towards the first end, and the elastic restoring force is in a direction towards the second end
Implementation Method 2
the diameter expanding element applies pressure to the movable sleeve and generates a movement stroke relative to the fixing sleeve
