Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-point pollutant processing device is installed in a concrete waterway or road slope, then the filtering function is provided, but the device is difficult to install and remove, and may be damaged by foreign materials
Solution Approach 1:
The filtering device is divided into multiple modular units that can be easily assembled and disassembled. Each module contains specific filtering components, allowing the device to be installed and removed in sections rather than as a single complex structure, thereby improving installation ease while maintaining filtering reliability
Solution Approach 2:
The device incorporates movable and adjustable components that allow it to adapt to different installation environments and be easily repositioned or removed. The dynamic structure enables the device to be installed on various surfaces including concrete waterways and road slopes without permanent fixation, facilitating easy removal and relocation
2Reliability
If a non-point pollutant processing device is installed in a concrete waterway or road slope, then the filtering function is provided, but the device is prone to damage from foreign materials such as earthy materials, traffic accident residues, and other foreign materials
Solution Approach 1:
The device incorporates protective structures and shock-absorbing elements that cushion against impacts from foreign materials before they can cause damage. The design includes reinforced protective barriers and flexible components that can withstand strikes from debris, earthy materials, and traffic accident residues, preventing damage to critical filtering components
Solution Approach 2:
The device uses flexible protective coverings and durable thin-film materials that can absorb and distribute the impact forces from foreign materials. These flexible protective layers prevent direct contact between harmful debris and the filtering mechanisms, maintaining device integrity while allowing the filtering function to continue operating
3Reliability
If traditional filtering devices are used, then basic filtration is provided, but maintenance is difficult and timely monitoring of cleaning needs and strainer replacement is not available
Solution Approach 1:
The device incorporates sensors and monitoring systems that continuously track the filtering performance, strainer condition, and pollutant accumulation levels. This feedback mechanism provides real-time information about when cleaning or strainer replacement is needed, enabling proactive maintenance scheduling and reducing the difficulty of maintaining optimal filtering operation
Solution Approach 2:
The monitoring system is designed to automatically detect and report maintenance needs without requiring manual inspection. The device essentially monitors itself, providing alerts and status information that guide maintenance activities, thereby simplifying the maintenance process and ensuring timely intervention before filtering effectiveness deteriorates
