Sensing and touch-controlled faucet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensing faucets often waste soap due to rapid water discharge after soap dispensing, leading to poor user experience.
Innovation Solution
A sensing and touch-controlled faucet design with a soap dispensing port located away from the water outlet and controlled by a soap sensor, ensuring soap is dispensed on the inner side of the user's fingers before water discharge, using a water flow sensor to control water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the water flow sensor rapidly detects hand motion and the water outlet immediately discharges water, then the response speed is improved, but the soap on the palm is washed away causing waste
Solution Approach 1:
The patent applies preliminary action by positioning the soap dispensing port to dispense soap onto the inner side of fingers before water discharge occurs. This ensures soap is already in place on the fingers when water flows, preventing soap waste while maintaining rapid response speed. The spatial arrangement creates a sequence where soap application precedes water discharge.
Solution Approach 2:
The patent changes the spatial dimension by moving the soap dispensing port from a position near the water outlet to a position at the side away from the water outlet. This dimensional repositioning allows soap to be dispensed onto the inner side of fingers, creating a spatial separation between soap application and water discharge paths, thus preventing soap washaway.
2Device complexity
If the soap dispensing port is located near the water outlet, then the device structure is simplified, but the discharged water rapidly washes the soap away
Solution Approach 1:
The patent resolves this contradiction by repositioning the soap dispensing port to the side away from the water outlet, changing its spatial dimension within the casing. This positional change prevents water from washing away soap while maintaining a relatively simple overall device structure. The mounting cavity integrates both components without adding significant complexity.
Solution Approach 2:
The patent applies local quality by creating different functional zones within the casing: the soap dispensing port is positioned in one local area (side away from water outlet) for soap application, while the water outlet remains in another local area. This local differentiation ensures each component performs its function optimally without interfering with the other.
3Loss of substance
If the soap dispensing port is positioned at the side away from the water outlet, then soap waste is prevented, but the device requires a larger mounting cavity
Solution Approach 1:
The patent merges the soap dispensing function and water outlet function within a single integrated casing structure. The mounting cavity accommodates both the water outlet and the repositioned soap dispensing port in a compact arrangement, avoiding the need for separate housing structures. This merging approach minimizes the overall volume required while maintaining the beneficial spatial separation.

AI summary
A sensing and touch-controlled faucet includes a casing, a covering plate, a water flow sensor, and a soap sensor. The casing has a water outlet arranged proximal to the bottom of a faucet working end, the casing also has a soap dispensing port and a mounting cavity communicating with the water outlet and the soap dispensing port, the soap dispensing port is arranged near the water outlet and the soap dispensing port is located at a side away from a faucet working end relative to the water outlet. When washing hands with the faucet, after the soap falls on the inner side of the fingers, if the motion of the hands is rapidly detected by the water flow sensor which then controls the water outlet to discharge water, the soap will not be easily washed away by the water flow.
