Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If floating bed technology is used for water purification, then water quality can be improved, but the device occupies large area and is difficult to construct and replace
Solution Approach 1:
The purification system is divided into modular components: support wall panels, filler biological walls, and trays that can be independently assembled and disassembled. Each support wall panel contains filler biological walls with adsorption materials, forming self-contained purification modules that can be easily installed by simply attaching them to the retaining wall structure.
Solution Approach 2:
The invention transitions from horizontal floating bed purification to vertical wall-mounted purification. By utilizing the vertical dimension of the retaining wall, the system achieves high purification capacity without occupying river channel area, and the vertical orientation facilitates easier installation and replacement compared to large floating structures.
2Reliability
If biological methods are used for water purification, then water quality can be improved, but the treatment process works slowly
Solution Approach 1:
The filler biological walls combine multiple purification mechanisms: adsorption materials (activated carbon, zeolite, bamboo charcoal) for rapid pollutant uptake, biological components (microorganisms, aquatic plants) for organic matter decomposition, and porous structures for enhanced surface area. This composite approach accelerates treatment by simultaneously deploying physical adsorption and biological degradation processes.
Solution Approach 2:
The system employs porous adsorption materials with high surface area to volume ratios, including activated carbon, zeolite, and bamboo charcoal layers. These porous structures provide extensive contact surfaces for rapid adsorption of organic pollutants and nutrients, significantly increasing treatment speed compared to conventional biological methods alone.
3Reliability
If chemical methods are used for water purification, then water quality can be improved, but toxic side effects and secondary pollution are caused
Solution Approach 1:
The purification system utilizes natural processes without requiring external chemical inputs. Adsorption materials naturally bind pollutants, microorganisms naturally decompose organic matter, and aquatic plants naturally absorb nutrients. This self-service approach eliminates the need for chemical additives, preventing toxic side effects and secondary pollution while maintaining effective water quality improvement.
4Area of stationary object
If vertical revetments are used in river channels, then land resources are saved, but the revetment area is more susceptible to pollution accumulation
Solution Approach 1:
The support wall panels serve as intermediary structures attached to the vertical revetment. These panels create a buffer zone between the polluted water and the revetment surface, using adsorption materials and biological components to intercept and remove pollutants before they can accumulate on the revetment, thus protecting the vertical structure while maintaining land-saving benefits.
