Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If buried tanks are used for rainwater storage, then storage capacity is achieved, but costly earthworks and installation are required
Solution Approach 1:
The storage system is divided into multiple modular tank units that can be stacked vertically. Each module is a self-contained unit with standardized dimensions and connection interfaces, allowing flexible assembly without extensive earthworks. The modular design enables installation on existing structures like building walls or freestanding locations.
Solution Approach 2:
The system transitions from horizontal ground-level expansion to vertical stacking, utilizing the vertical dimension for storage capacity. This eliminates the need for costly earthworks and ground leveling while achieving the same or greater storage volume through vertical stacking of modular units.
2Volume of stationary object
If buried tanks are used for rainwater storage, then storage capacity is achieved, but pumping means are required for water extraction
Solution Approach 1:
The stacked modular tanks are positioned at different heights to create gravitational potential difference. Water flows automatically from upper to lower tanks through gravity-driven flow channels, eliminating the need for pumping systems. The highest tank receives roof runoff, and gravity naturally distributes water to lower storage modules.
Solution Approach 2:
The system uses its own gravitational potential energy to circulate and distribute water among modules. The built-in flow channels and water level sensors enable automatic water redistribution without external intervention or mechanical pumping, reducing device complexity and maintenance requirements.
3Adaptability or versatility
If external modular tanks are used, then installation on existing buildings is possible, but structural integration and stability are insufficient
Solution Approach 1:
The tank modules are integrated with the building structure through direct attachment to load-bearing walls or structural elements. The modules serve dual purposes: water storage and potential structural reinforcement, as they are anchored into the building's framework rather than merely attached to the surface.
Solution Approach 2:
The tank modules utilize composite construction materials that combine structural strength with water storage functionality. The modules are made from reinforced materials that provide both the necessary mechanical strength for structural integration and the waterproofing properties required for water storage.
4Ease of manufacture
If modular elements are stacked without structural connection, then assembly is simplified, but sealing and structural integrity are compromised
Solution Approach 1:
Sealing gaskets and intermediate sealing layers are placed between stacked tank modules to ensure waterproof connections. These intermediary sealing elements maintain the simplicity of modular assembly while guaranteeing reliable sealing integrity, preventing water leakage at joint interfaces.
Solution Approach 2:
The modular connection system serves multiple functions simultaneously: mechanical attachment, structural alignment, and waterproof sealing. The standardized interfaces integrate fastening mechanisms with built-in sealing features, eliminating the need for separate sealing components while maintaining assembly simplicity.

The system enables efficient rainwater collection and storage without costly earthworks, integrates seamlessly with existing structures, and reduces maintenance needs, while providing a functional and aesthetic wall solution that captures and stores rainwater for reuse.
Implementation Method 1
the column of water thus stored ensures the flow and the pressure necessary for its emptying, without involving pumping means
Implementation Method 2
the filling of the upper element induces the flow of the liquid which it encloses, until the lower element is filled
