Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If rainwater pipelines are used to drain rainwater, then drainage function is achieved, but rainwater resource is wasted and pollution is aggravated
Solution Approach 1:
The drainage system is segmented into separate functional components: rainwater collection pipelines for resource utilization, and pollution control pipelines for contaminated water. This segmentation allows rainwater to be diverted from the drainage system for beneficial uses while directing polluted runoff to appropriate treatment facilities, thereby reducing resource waste and pollution simultaneously.
Solution Approach 2:
A rainwater collection and utilization system is introduced as an intermediary between the rainwater source and the drainage system. This intermediary system captures rainwater before it enters the drainage pipeline, treating and storing it for later use in irrigation, road cleaning, and other non-potable applications, thus preventing both resource loss and pollution.
2Productivity
If rainwater utilization facilities are built at individual project level, then local rainwater use is improved, but regional large-scale systematic use cannot be achieved
Solution Approach 1:
Multiple individual rainwater utilization facilities are merged into a unified regional rainwater management system. The system integrates collection facilities from various buildings and areas, treatment facilities, storage facilities, and distribution networks into a coordinated regional infrastructure that achieves both high utilization rates and systematic regional management.
Solution Approach 2:
The regional rainwater system is designed with multi-functionality to serve diverse purposes: flood control, water resource supplementation, pollution prevention, and ecological protection. The system can adaptively allocate rainwater to different uses based on regional needs, achieving both high productivity and broad adaptability across the region.
3Ease of operation
If surface runoff enters rivers and lakes through drainage pipelines, then drainage is achieved, but water body pollution is aggravated
Solution Approach 1:
Clean rainwater is extracted from the mixed stormwater runoff before it enters the drainage system. Separate rainwater collection facilities capture clean precipitation from roofs and paved areas, extracting this valuable resource away from the pollution-generating drainage pathway and directing it to utilization facilities, thereby eliminating the source of pollution while maintaining drainage functionality for contaminated water.
