Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dual-outlet faucets face challenges such as limited flexibility in water outlet positions, difficulty in accommodating multiple water supply modes, and inconvenient maintenance due to the integration of tap water and water filter pipelines, as well as inadequate design for hot water control and error prevention.
Innovation Solution
A faucet design featuring a main body with separate control devices for cold and hot water, a drive device using a magnetically repelled clutch shaft to automatically lock and unlock the hot water control mechanism, eliminating the need for conventional springs and reducing friction, thus enhancing safety and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a dual-outlet tube structure is used to combine tap water and water filter pipelines, then the faucet structure is integrated and compact, but the outlet position flexibility is limited and maintenance becomes inconvenient
Solution Approach 1:
The patent divides the water supply system into separate cold water and hot water control devices, each with independent control mechanisms. The outlet device is also segmented into multiple independent outlets that can be selectively activated. This segmentation allows flexible operation of different outlets while maintaining an integrated overall structure.
2Adaptability or versatility
If multiple water supply modes are accommodated in a single faucet structure, then the faucet provides versatile functionality, but the structural complexity increases and assembly becomes difficult
Solution Approach 1:
The patent implements multi-functionality through separate control devices for cold and hot water, each capable of independent operation. The outlet device can deliver different types of water (tap water, filtered water, cold, hot) through its multiple outlets. This universal design allows the single faucet structure to accommodate multiple water supply modes without requiring separate faucets for each function.
3Device complexity
If conventional spring mechanisms are used for the drive device, then the structure is simple, but friction increases and lifespan is reduced
Solution Approach 1:
The patent replaces the conventional spring-based mechanical drive device with a magnetic drive device that uses magnetic fields to actuate the control valve. This substitution eliminates direct mechanical contact and friction between moving parts, significantly reducing wear and extending the faucet's operational lifespan while maintaining reliable operation.
4Reliability
If magnetic repulsion is used for non-contact locking, then friction is reduced and lifespan is extended, but the device complexity increases
Solution Approach 1:
The patent employs magnetic repulsion between a first magnet on the clutch shaft and a second magnet on the drive device to create non-contact locking and unlocking mechanisms. This magnetic field-based approach replaces traditional mechanical locking components, reducing friction and wear while extending the faucet's operational lifespan. The magnetic drive device integrates these components efficiently, managing the complexity through unified magnetic actuation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides a safe and flexible operation mode by preventing error operations and extending the faucet's lifespan through non-contact magnetic locking, while also enabling a saving-water control mechanism by automatically closing the hot water passage after use.
Implementation Method 1
a second magnet is disposed on the clutch shaft, wherein the first magnet and the second magnet repel each other and the repelled first magnet and second magnet form a restituting force for the clutch shaft when the clutch shaft inwardly moved relative to the casing

AI summary
A faucet has a main body, a cold water control device mounted onto a first end of the main body, a hot water control device mounted onto a second end of the main body and an outlet device mounted onto a top of the main body. The cold water control device selectively guides cold water flowing into the main body and flowing out from the outlet device. A drive device is laterally mounted onto the hot water control device for driving the hot water control device to selectively guide hot water flowing into the main body and flowing out from the outlet device. The drive device has a first magnet secured to a tube in a casing of the drive device and a second magnet disposed on a clutch shaft of the drive device to provide a repelling force for the clutch shaft.
