Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water purification systems require manual purging, which is cumbersome and risky, especially for non-technical users, and may lead to contamination or reduced filter effectiveness, while also not ensuring the highest water quality consistently.
Innovation Solution
A closed water flow loop system with automatic purging capabilities using diversionary and return pipes to evacuate residual gases from filtration means, ensuring the integrity and quality of the purified water, and incorporating UV sterilization to maintain system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual purging is implemented, then air pockets can be removed from filters, but user operation complexity and contamination risk increase
Solution Approach 1:
The system performs purging automatically without user intervention. The control unit monitors pressure differential across filters and activates purge valves when needed, enabling the system to self-maintain optimal filtration performance.
Solution Approach 2:
The control unit continuously monitors pressure differential across the filters and uses this feedback to determine when purging is needed. This closed-loop control ensures purging occurs only when necessary, maintaining optimal filter performance automatically.
2Object-affected harmful factors
If manual purging is performed, then air pockets can be evacuated, but water quality and system reliability deteriorate due to contamination risk
Solution Approach 1:
The system automatically performs purging operations based on monitored filter conditions, eliminating human error and contamination risk associated with manual operation. The control unit manages the entire purging process sterilely without user intervention.
Solution Approach 2:
Continuous pressure monitoring provides real-time feedback on filter status, enabling the control unit to initiate purging only when air pockets are detected. This precise control prevents unnecessary purging that could compromise water quality while ensuring purging occurs when needed.
3Ease of operation
If filtration continues without purging, then system operation is simple, but head loss increases and flow rate decreases
Solution Approach 1:
The system performs purging periodically based on pressure differential thresholds rather than continuously. The control unit monitors filter pressure and activates purging cycles when air pockets are detected, maintaining optimal flow rate with minimal intervention.
Solution Approach 2:
The control unit uses pressure differential feedback to determine when purging is needed to maintain flow rate. This ensures the system operates at optimal productivity by purging only when filter resistance increases due to air pockets.
4Device complexity
If manual purging is required, then system structure is simpler, but maintenance difficulty and user burden increase
Solution Approach 1:
The control unit automatically manages purging operations based on filter condition monitoring, eliminating the need for users to manually operate purge valves. The system self-diagnoses and self-maintains optimal filter performance throughout operation.
Solution Approach 2:
Continuous pressure monitoring provides feedback on filter status, enabling the control unit to automatically initiate purging when needed. This reduces maintenance burden by eliminating the need for users to know when or how to perform manual purging.
