Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water controllers in humidifiers often suffer from mechanical failures due to the easy damage of components used to control water flow, and they require additional pumping devices, increasing resource consumption and complexity.
Innovation Solution
A water controller utilizing a magnetic control assembly and an electromagnet to switch the connection state between a water tank and a water trough, allowing water to flow only when the water level in the trough is below a predefined height, thus prolonging the device's lifespan and eliminating the need for additional pumping by using gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical components are used to control water flow, then the water controller can effectively manage water levels, but the components are prone to damage and mechanical failures
Solution Approach 1:
The patent replaces traditional mechanical control components with a magnetic control assembly that uses magnetic fields to control the opening and closing of the water inlet. The magnetic control assembly includes a magnetic attraction component and a magnetic field generation component, eliminating complex mechanical linkages and moving parts that are prone to wear and failure.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the control system and the water flow control mechanism. The magnetic field generation component creates a magnetic field that acts on the magnetic attraction component to control the valve opening, serving as a non-contact intermediary that transmits control force without mechanical contact.
2Productivity
If additional pumping devices are added to control water flow, then water can be delivered to the water trough, but resource consumption increases and device complexity increases
Solution Approach 1:
The patent utilizes the natural gravity-driven flow of water from the water tank to the water trough. The water outlet of the water tank is positioned higher than the water inlet of the water trough, allowing water to flow downward automatically without requiring external pumping energy. The magnetic control assembly only needs to regulate the opening/closing state, not provide the driving force.
Solution Approach 2:
The patent positions the water outlet and water inlet at different heights to create a gravitational potential difference that drives water flow. By utilizing this height difference, the system converts gravitational potential energy into kinetic energy for water delivery, eliminating the need for additional energy-consuming pumping devices.
