Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing induction kitchen faucets are unreliable as they cease functioning when the induction device fails or the power supply is cut off, leading to inconvenience in use.
Innovation Solution
A mechanical and electronic dual control water tap system that includes a mixing valve with separate inlets and outlets for cold and hot water, an inductor flowmeter, and solenoid valves, allowing for independent operation of mechanical and electronic controls, ensuring continuous water supply even without power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an induction kitchen faucet is used for non-contact water control, then convenience and ease of operation are improved, but reliability deteriorates when the induction device fails or power is cut off
Solution Approach 1:
The water supply system is segmented into two independent control paths: an electronic induction control path and a mechanical control path. Each path can operate independently, ensuring that failure in one path does not affect the other. The mechanical control path includes a separate inlet valve and control mechanism that functions without electrical power.
Solution Approach 2:
A mechanical control backup system is built into the design beforehand to cushion against potential failures of the electronic induction system. This includes mechanical valves and manual control mechanisms that are pre-positioned to take over immediately when electronic control fails or power is unavailable.
2Reliability
If a dual control system with separate mechanical and electronic outlets is implemented, then reliability is improved by enabling continuous operation, but device complexity increases
Solution Approach 1:
The mechanical and electronic control systems are merged into a unified faucet structure with shared components such as the valve body, water channels, and outlet nozzle. This integration reduces the need for completely separate systems while maintaining independent operation capabilities.
Solution Approach 2:
The faucet body and valve mechanisms are designed to serve multiple functions: electronic induction control for normal operation, mechanical control for backup operation, and temperature mixing functionality. This multi-functionality reduces the need for additional specialized components.
