Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Humidifiers with existing humidifying materials face performance degradation due to clogging from silica and mineral components in water, leading to unstable water supply and reduced humidifying efficiency over time.
Innovation Solution
A humidifier system with a controller that adjusts water supply based on detected humidity and temperature changes, using a humidifying material with a scale component to enhance performance by controlling water flow rates to prevent scale accumulation, thereby maintaining efficient humidification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hydrophilic treatment is performed on the humidifying material to enhance water absorption, then humidifying performance is improved, but organic substances and scales accumulate over time causing holes to clog and performance to degrade
Solution Approach 1:
The control unit monitors humidifying performance indicators (such as humidity output or water consumption patterns) and automatically adjusts water supply parameters or triggers maintenance protocols when performance degradation is detected, creating a closed-loop system that responds to actual operating conditions
Solution Approach 2:
The system performs preliminary hydrophilic treatment during manufacturing or initial operation, and incorporates scheduled maintenance cycles that proactively clean or re-treat the humidifying material before complete clogging occurs, based on usage time or performance threshold predictions
2Productivity
If water supply amount is increased to maintain humidification output, then humidifying performance is maintained, but scale accumulation accelerates and clogs the humidifying material
Solution Approach 1:
The control unit dynamically adjusts water supply parameters (flow rate, pressure, or timing) based on detected humidifying performance, operating conditions, and accumulated usage time, optimizing the balance between maintaining output and minimizing scale deposition
Solution Approach 2:
The system implements periodic flushing cycles or intermittent high-flow cleaning pulses that temporarily increase water supply to dislodge and remove accumulating scales, followed by normal operation phases, preventing complete clogging
3Object-generated harmful factors
If water supply is restricted to prevent scale accumulation, then scale deposition is reduced, but water supply stability decreases and humidifying performance deteriorates
Solution Approach 1:
The water supply system transitions from static fixed-flow operation to dynamic control where flow rate, pressure, and timing are continuously adjusted based on real-time feedback from sensors monitoring humidifying performance, water quality, and system operating conditions
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 system effectively maintains high humidifying performance by using the scale component to prevent clogging and enhance water retention, reducing the need for frequent hydrophilic treatment and extending the humidifier's lifespan.
Implementation Method 1
Evaporative humidifiers perform humidification of air by causing the air to pass through a humidifying material having a water absorption function and thus allowing heat exchange between moisture contained in the humidifying material and an air flow to vaporize and evaporate
Implementation Method 2
allowing heat exchange between moisture contained in the humidifying material and an air flow to vaporize and evaporate
Implementation Method 3
causing scales to be accumulated on the humidifying material
Implementation Method 4
a first temperature and humidity sensor that detects a temperature and a humidity of the air before passing through the humidifying material; a second temperature and humidity sensor that detects a temperature and a humidity of the air after passing through the humidifying material

AI summary
A humidifier obtains, based on detection values of a first and second temperature and humidity sensors, the amount of humidification, the amount of water evaporated by a humidifying material per preset time, controls the amount of water supplied by a water supply unit per the preset time to be smaller than a specific value when the amount of humidification obtained at the present time is increased compared to the amount of humidification obtained at the previous time, and controls the amount of water supplied by the water supply unit per the preset time to be equal to or greater than the specific value when the amount of humidification obtained at the present time is decreased compared to the amount of humidification obtained at the previous time or when the amount of humidification obtained at the present time is equal to the amount of humidification obtained at the previous time.
