Water Purifier Processor Adjusts Ejection Using Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water purifiers face challenges in accurately ejecting a predetermined amount of water due to various influencing factors, such as water level in the storage tank and raw water pressure, leading to inconsistencies in the amount of water dispensed, making it difficult for users to set and receive their desired water ejection amount.
Innovation Solution
A water purifier equipped with a housing, filter, control valve, factor value measurement sensor, and input panel, where a processor adjusts the water ejection based on user input and factors like temperature, water storage, and pressure, using correction values to ensure accurate dispensing of the set amount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water ejection time is controlled based on user input, then user convenience is improved, but water ejection precision deteriorates due to influencing factors
Solution Approach 1:
The system measures the actual water ejection amount using a flow rate sensor and compares it with the target amount. Based on this feedback, the processor adjusts the water ejection time in real-time to compensate for variations caused by water level and pressure changes, ensuring precise water delivery while maintaining ease of operation.
Solution Approach 2:
The system dynamically changes the water ejection time parameter based on measured water level and pressure conditions. Instead of using a fixed time value, the processor calculates the optimal ejection time by considering the current state of the system, thereby maintaining precision across different operating conditions.
2Device complexity
If fixed preset water ejection amounts are provided, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The system transitions from static preset values to dynamic calculation of water ejection time. The processor continuously adjusts the ejection parameters based on real-time measurements of water level and pressure, enabling the system to adapt to various conditions without requiring complex user input or multiple preset options.
Solution Approach 2:
The system automatically measures water level and pressure, calculates the appropriate ejection time, and executes the water delivery without user intervention. This self-adjusting mechanism provides adaptability while keeping the user interface simple, effectively reducing perceived device complexity.
3Quantity of substance
If water ejection time is extended to compensate for lower water level, then water ejection amount is maintained, but time consumption increases
Solution Approach 1:
Instead of simply extending ejection time, the system changes multiple parameters simultaneously: it adjusts ejection time while also modifying ejection pressure and flow rate. This multi-parameter optimization ensures the target water amount is delivered efficiently without excessive time consumption.
Solution Approach 2:
The system performs preliminary measurement of water level and pressure before initiating water ejection. Based on these pre-measured values, it calculates the optimal ejection parameters in advance, preventing both insufficient and excessive ejection times, thereby optimizing the balance between water amount and time consumption.
