Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional water-retaining buildings and ecological slopes are constructed, then river course treatment is attempted, but the systems are single and unconnected, destroying water ecological environment and biodiversity
Solution Approach 1:
The patent combines multiple treatment systems (plastic retaining dams, ecological biological water purification systems, and damp land ecological water purification systems) into an integrated networked system. These systems are connected through water channels and biological corridors, allowing them to work synergistically rather than as isolated units, thereby improving treatment effectiveness while preserving ecological balance.
Solution Approach 2:
The river course is divided into multiple retaining regions by plastic retaining dams, with each region containing an ecological biological water purification system. This segmentation allows for step-by-step treatment throughout the river course, creating multiple treatment stages that work together to purify water while maintaining ecological diversity across different zones.
2Reliability
If conventional treatment techniques are used, then some purification is achieved, but the systems take much time, entail much work, and incur high costs
Solution Approach 1:
The patent implements continuous water flow through the system, with water moving sequentially through multiple retaining regions and purification systems. The damp land ecological water purification system continuously receives water from upstream and discharges purified water downstream, maintaining uninterrupted purification action that reduces overall treatment time compared to batch processing methods.
Solution Approach 2:
The plastic retaining dams and ecological biological water purification systems are pre-installed in the river course to create ready-to-operate treatment zones. The systems are designed with pre-established biological communities and structural configurations that enable immediate purification action upon water flow, eliminating setup time and enabling rapid deployment.
3Productivity
If plastic retaining dams and ecological biological water purification systems are deployed, then step-by-step treatment is achieved, but device complexity increases
Solution Approach 1:
The patent designs standardized plastic retaining dams and ecological biological water purification systems that can be replicated across multiple retaining regions. Each module serves multiple functions: water retention, purification, and ecological habitat creation. This modular universality allows complex treatment functionality to be achieved through repeated simple units rather than a single complex system, making the overall system more manageable despite its scale.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system significantly enhances sewage purification efficiency, reduces treatment costs, and improves the water ecological environment by utilizing plastic retaining dams and biological water purification units in conjunction with aquatic plants, effectively addressing the limitations of conventional methods.
Implementation Method 1
The aquatic plants, including submerged plants, floating plants, and emerged plants, are highly adaptive and effective in purifying sewage
Implementation Method 2
The aquatic plants, including submerged plants, floating plants, and emerged plants, are highly adaptive and effective in purifying sewage
Implementation Method 3
The plastic retaining dams divide the river course into retaining regions arranged in the direction from the upstream portion to the downstream portion of the river course
Implementation Method 4
The rainwater channel is disposed beside and along the river course and has draining vents whereby water is discharged from the rainwater channel into the river course
