Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to activate vacuum wastewater devices, then device complexity is reduced, but productivity and reliability deteriorate due to insufficient pressing, defective buttons, and lack of feedback
Solution Approach 1:
The system performs self-diagnosis and self-reporting through integrated sensors and communication modules. The vacuum wastewater device automatically monitors its own operation status, blockage conditions, and extraction effectiveness, eliminating the need for manual checking and providing automated feedback to the control unit.
Solution Approach 2:
The patent replaces manual mechanical operation with automated electronic control. Sensors detect operational parameters and trigger vacuum activation automatically, substituting the mechanical button-pressing action with an electronic control system that ensures reliable and consistent operation without human intervention errors.
2Device complexity
If manual operation is used, then device complexity is reduced, but loss of information occurs as no feedback is provided on valve opening or extraction performance
Solution Approach 1:
The system incorporates multiple sensors that continuously monitor extraction parameters such as vacuum level, flow rate, and blockage conditions. This feedback is transmitted to the control unit, which adjusts operation accordingly and provides status information, ensuring complete information availability about extraction performance and system state.
3Productivity
If a predetermined time period is waited for extraction, then productivity is improved, but reliability deteriorates as solids may block suction ports and prevent complete extraction
Solution Approach 1:
The system dynamically adjusts the extraction process based on real-time sensor feedback. Rather than using a fixed predetermined time, the control unit continuously monitors extraction effectiveness and adapts the operation duration and intensity to actual conditions, extending extraction when blockages are detected and ensuring complete removal of wastewater.
Solution Approach 2:
The system performs preliminary detection of blockage conditions during the extraction process through sensors that monitor vacuum levels and flow characteristics. When potential blockages are detected early, the control unit can take preliminary actions such as adjusting vacuum intensity or extending extraction time before complete blockage occurs, ensuring reliable extraction.
4Productivity
If multiple vacuum wastewater devices are used in a network, then productivity is improved, but device complexity increases and coordination becomes difficult
Solution Approach 1:
The patent implements a universal communication protocol and standardized interface that enables different vacuum wastewater devices to interact seamlessly within the network. Each device possesses multi-functionality, serving both as an independent extraction unit and as a networked component, with the ability to communicate status, receive commands, and coordinate with other devices through a common control language.
