Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used to connect the detection module to the pump, then reliable signal transmission is achieved, but installation complexity and infrastructure modification requirements increase
Solution Approach 1:
The patent replaces wired mechanical/electrical connections with wireless communication technology. The detection module transmits signals wirelessly to the pump control unit, eliminating the need for physical cable connections and infrastructure modifications while maintaining reliable signal transmission.
Solution Approach 2:
The patent introduces a wireless communication intermediary (radio frequency signal) to transmit control signals between the detection module and pump control unit. This intermediary enables communication without direct physical connection, simplifying installation while ensuring reliable signal transmission.
2Reliability
If the detection module is integrated into the container infrastructure, then sealing and structural integrity are improved, but flexibility of installation and maintenance are reduced
Solution Approach 1:
The patent divides the liquid discharge system into separate functional modules: a detection module that can be independently installed in the container, and a pump control unit that remains external. This segmentation allows the detection module to be easily installed and removed without affecting the overall infrastructure, maintaining both sealing integrity and installation flexibility.
Solution Approach 2:
The detection module is designed as a self-contained unit with integrated wireless communication capabilities, requiring no external wiring or complex integration. It can be independently installed in the container and automatically communicates with the pump control unit, enabling easy installation and maintenance while ensuring proper sealing.
3Productivity
If the pump is located close to the container, then liquid evacuation efficiency is improved, but space constraints and installation difficulty increase
Solution Approach 1:
The patent uses wireless communication as an intermediary to enable remote control of the pump. The detection module can trigger the pump to operate even when located at a distance, allowing the pump to be positioned in locations with better space availability while maintaining efficient liquid evacuation capability.
