Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a storage/seepage system uses a water-permeable casing for infiltration, then rainwater can seep into the ground in a defined quantity and speed, but the casing becomes clogged by solid deposits and sediment after a short time, blocking water drainage
Solution Approach 1:
The system is divided into multiple functional sections: a first section for coarse solids retention, a second section for light liquids retention, and a third section with filter elements. This segmentation allows each section to handle specific types of contamination, preventing overall system clogging while maintaining water drainage capability.
Solution Approach 2:
The purification stage performs preliminary cleaning of rainwater before it reaches the storage and infiltration sections. By removing solids, light liquids, and fine particles in advance, the system prevents clogging of the water-permeable casing, ensuring long-term reliability of water drainage.
2Strength
If the storage/seepage system is equipped with numerous struts for structural stability, then the area above can be used as a roadway or parking lot, but cleaning of the system becomes hardly possible or not possible at all
Solution Approach 1:
The purification stage is extracted as a separate functional unit with its own access points and maintenance capabilities. This allows cleaning and maintenance operations to be performed on the purification components without disturbing the structural hollow bodies and their struts, maintaining both structural stability and cleaning accessibility.
Solution Approach 2:
The purification stage is designed to be self-maintaining through automated backwashing of filter elements and removable components that can be easily accessed for cleaning. This reduces the need for complex manual intervention while preserving the structural integrity of the overall system.
3Area of stationary object
If a purification stage is integrated into the storage/infiltration stage, then space requirements are reduced and installation effort is minimized, but the system complexity increases
Solution Approach 1:
The purification stage is merged with the storage/infiltration stage by integrating it into the hollow bodies, using the same structural framework and support struts. This combining approach reduces overall space requirements and minimizes the number of separate installation steps while maintaining functional separation through internal compartmentalization.
Solution Approach 2:
The hollow bodies serve multiple functions: they provide structural support for the roadway/parking lot, contain the purification stage, and serve as storage and infiltration chambers. This multi-functionality reduces the need for separate structures, thereby reducing space requirements and simplifying installation.
