Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic plumbing systems face difficulties in user interaction and control, particularly in residential and commercial applications, where intuitive and efficient control mechanisms are lacking.
Innovation Solution
An electronic plumbing system with gesture control is introduced, utilizing an activation sensor/display assembly mounted on the faucet or wand to activate, deactivate, and control water flow based on user gestures, eliminating the need for manual handles or additional input devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If gesture control with a single sensor is implemented, then device complexity is reduced, but measurement precision may be compromised
Solution Approach 1:
The patent replaces complex mechanical sensor arrays with a single optical sensor that uses optical fields to detect gestures. This substitution reduces the physical complexity of the device while maintaining detection capability through sophisticated optical measurement and signal processing algorithms.
Solution Approach 2:
The system compensates for the single sensor limitation by dynamically changing measurement parameters and using multiple detection dimensions. The control system analyzes various optical parameters (intensity, position, movement patterns) from the single sensor to achieve comprehensive gesture recognition, effectively compensating for the reduced hardware complexity.
2Ease of operation
If manual handles or additional input devices are eliminated, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system enables self-service operation where the faucet automatically detects user intentions through gestures and activates water flow without requiring manual handles or additional input devices. The single optical sensor continuously monitors for gestures and automatically controls the valve, eliminating the need for traditional manual controls.
Solution Approach 2:
The patent replaces mechanical handle controls with an optical detection system. Instead of mechanical switches or handles, the system uses optical fields to detect hand gestures and translates them into control signals, thereby eliminating manual mechanical interfaces while adding intelligent control capabilities.
