Water Purifier Preparation Timing Control to Reduce Storage Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water purifiers often produce excess purified water, leading to unsuitable storage conditions when usage patterns are not accurately predicted, resulting in inadequate water availability for immediate needs.
Innovation Solution
A method and control apparatus that determine water usage amount and time for an object, calculate the required preparation time based on the water usage amount, water preparation speed, and residual water, and initiate water preparation accordingly to ensure the right amount of purified water is available when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If water purifier stores large amount of pure water in advance, then water availability for future use is improved, but water quality deteriorates overnight making it unsuitable for drinking
Solution Approach 1:
The system performs preliminary calculation of water preparation time based on usage amount and speed, then initiates water preparation in advance at the determined start time, ensuring water is ready exactly when needed without excessive storage
Solution Approach 2:
The system continuously monitors residual water amount and compares it with calculated requirements, adjusting water preparation timing and quantity dynamically to maintain optimal water quality and quantity balance
2Loss of substance
If water purifier prepares exact amount of water based on usage prediction, then water waste is reduced, but system complexity increases due to calculation requirements
Solution Approach 1:
The water purifier autonomously calculates water usage amount, preparation time, and start time using built-in processor and sensors, then automatically executes water preparation without user intervention, reducing water waste while maintaining manageable system complexity through self-contained control logic
3Loss of time
If water purifier calculates precise water preparation time, then water availability timing is improved, but measurement and calculation precision requirements increase
Solution Approach 1:
The system calculates water preparation time in advance using measured usage amount and predetermined preparation speed, then starts water preparation at the calculated start time, achieving accurate timing while using reasonable measurement precision through the formula: preparation time = usage amount / preparation speed
