Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a predetermined extraction time is used to empty wastewater reservoirs, then the extraction process can be completed within a limited time frame, but solids may block the suction port and prevent complete extraction
Solution Approach 1:
The patent employs sensor arrangements that detect pressure differences across the vacuum wastewater device to provide real-time feedback on extraction status. The electronic control unit continuously monitors these pressure values and automatically adjusts the extraction process, extending or terminating it based on actual wastewater removal status rather than fixed timing, thereby ensuring complete extraction even when solids are present
Solution Approach 2:
The system dynamically adapts the extraction process by continuously monitoring pressure differential values and adjusting operation accordingly. The electronic control unit modifies extraction parameters in real-time based on sensor feedback, transforming the static predetermined-time approach into a dynamic response system that reacts to actual extraction conditions
2Ease of operation
If manual operation of vacuum wastewater devices is used, then the device can be activated by user input, but there is no feedback to confirm the vacuum valve has opened or extraction is occurring
Solution Approach 1:
The patent incorporates sensor arrangements that detect pressure differences and provide real-time feedback signals to the electronic control unit. This feedback loop confirms whether the vacuum valve has opened and whether extraction is actively occurring, giving the operator definitive information about system status and operation effectiveness
3Productivity
If multiple vacuum wastewater devices are used in large wastewater networks, then more reservoirs can be emptied simultaneously, but energy efficiency is reduced without optimized control
Solution Approach 1:
The electronic control units in multiple vacuum wastewater devices communicate and coordinate based on sensor feedback from pressure differential detection. This enables optimized control where devices can be dynamically activated or deactivated based on network conditions and extraction needs, improving energy efficiency while maintaining high throughput in large wastewater networks
Solution Approach 2:
The system dynamically coordinates multiple vacuum wastewater devices based on real-time pressure differential measurements and extraction status. The electronic control units adjust operation timing and duration for each device optimally, transforming static simultaneous operation into dynamic coordinated control that balances productivity with energy efficiency
