Solution Overview
Problem
Existing water treatment devices risk damage due to contaminated water entering the pump, as current systems lack effective mechanisms to ensure proper filtration before recirculation.
Innovation Solution
Incorporating a signal transmitter and sensor system that only allows the water treatment device to operate in working mode if a correctly positioned filter device is detected, preventing contaminated water from entering the pump, using a magnet and Hall sensor for precise positioning and filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter device is used to filter contaminated water, then the pump is protected from damage, but the system may not detect improper filter positioning leading to potential damage
Solution Approach 1:
The patent applies preliminary action by implementing a detection system that checks filter device positioning before the pump operates. The signal transmitter and sensor detect whether the filter device is properly positioned in advance, preventing contaminated water from entering the pump before damage can occur.
Solution Approach 2:
The patent implements feedback through a control unit that receives signals from the sensor about filter device positioning. The system provides feedback by comparing the detected position with the required position and controlling the pump operation accordingly, ensuring the pump only runs when the filter is correctly positioned.
2Reliability
If a signal transmitter and sensor system is added to detect filter device positioning, then pump damage is prevented, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical detection systems with a simpler electromagnetic detection system. The signal transmitter (with magnet) and Hall sensor use magnetic field detection instead of mechanical switches or complex position sensors, reducing mechanical complexity while maintaining reliable detection of filter device positioning.
Solution Approach 2:
The patent uses the magnetic field as an intermediary between the filter device and the detection system. The magnet on the signal transmitter creates a magnetic field that the Hall sensor detects, allowing non-contact detection of filter device positioning and eliminating the need for direct mechanical contact or complex wiring.
3Reliability
If the water treatment device only operates in working mode when filter device is correctly positioned, then only filtered water enters the pump, but user operation becomes more restricted
Solution Approach 1:
The patent implements self-service by having the system automatically monitor filter device positioning and control pump operation without requiring user intervention. The control unit continuously checks the signal from the sensor and automatically prevents pump operation when the filter is improperly positioned, eliminating the need for manual checks or user decisions.
Solution Approach 2:
The system provides continuous feedback to the user through the control unit about whether the filter device is correctly positioned. This feedback mechanism guides the user to properly install the filter device while automatically controlling pump operation, balancing operational restrictions with user-friendly guidance.
