Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soakaway/infiltration tanks are used to store runoff water, then flooding risk is reduced and groundwater recharge is improved, but the tanks cannot be used in areas with inefficient percolation rates due to inadequate discharge capacity
Solution Approach 1:
The system employs dynamically adjustable discharge control means that can modify the discharge rate based on real-time conditions. The control means responds to water level signals and weather forecast data, adjusting the discharge rate dynamically to match the actual percolation capacity of the ground, thereby enabling reliable operation across varying percolation rates.
Solution Approach 2:
The system incorporates feedback mechanisms through water level sensors that continuously monitor the water level in the infiltration tank and send signals to the discharge control means. This feedback loop enables the system to automatically adjust discharge rates, ensuring the tank empties efficiently regardless of ground percolation characteristics, thus resolving the adaptability issue.
2Productivity
If the infiltration means discharges stored water quickly to provide storage capacity for subsequent storms, then flooding is avoided, but the discharge rate may exceed the percolation capacity of the surrounding ground in areas with inefficient percolation rates
Solution Approach 1:
The discharge control means dynamically adjusts the discharge rate based on real-time water level signals and weather forecast data. This dynamic control ensures the discharge rate matches the ground's actual percolation capacity, preventing overflow while maximizing water discharge efficiency in areas with inefficient percolation rates.
Solution Approach 2:
The system receives weather forecast data in advance and performs preliminary actions by adjusting the discharge rate before significant rainfall events. This allows the system to proactively manage water levels, ensuring the infiltration tank is ready to receive subsequent stormwater while maintaining a discharge rate that does not exceed ground percolation capacity.
3Adaptability or versatility
If control means is added to regulate discharge based on weather forecast data, then the system can operate in areas with varying infiltration rates, but the device complexity increases
Solution Approach 1:
The system employs self-service mechanisms where water level sensors automatically detect when the tank needs emptying and trigger the discharge control means without human intervention. The control means autonomously responds to weather forecast data and adjusts discharge rates, reducing the need for complex manual control systems while maintaining high adaptability to different infiltration rates.
Solution Approach 2:
The system replaces complex mechanical control mechanisms with electronic and computational approaches. Weather forecast data is processed electronically, and discharge control is achieved through electronically actuated mechanisms rather than purely mechanical systems, reducing overall device complexity while enhancing adaptability to varying infiltration conditions.
