Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a traditional water reservoir system is installed, then rainwater can be collected and stored, but it requires additional reservoirs or tanks that increase device complexity and installation difficulty
Solution Approach 1:
The patent merges the water storage function with the roof structure itself by integrating containers into the roofing elements. The containers are incorporated within the roof framework, eliminating the need for separate external reservoirs or tanks. This integration combines the roofing and water storage functions into a single unified system, reducing overall device complexity while maintaining rainwater collection capability.
Solution Approach 2:
The containers are nested within the roof framework and receptacles, with the receptacle holding the container in place. This nested arrangement allows the water storage function to be embedded within the existing roof structure without requiring additional external space. The connector system enables nested containers to be linked together, forming an integrated water management system that utilizes the roof's structural space efficiently.
2Productivity
If a modular container system with connectors is used, then rainwater can be harvested and distributed efficiently, but the device complexity increases
Solution Approach 1:
The roof system is segmented into multiple modular containers that can be independently installed on different roof sections. Each container is equipped with connectors that enable them to be linked together, forming a distributed water harvesting network. This segmentation allows the system to handle large volumes of rainwater across extensive roof areas while maintaining modular ease of installation and local water management capability.
Solution Approach 2:
The connectors are designed with universal compatibility, allowing the same connector type to interface with multiple container units. This universal connection system enables flexible arrangement and configuration of containers based on roof geometry and water harvesting requirements. The multi-functional connectors serve as both mechanical linkages and fluid conduits, simplifying the overall system architecture while maintaining high productivity in rainwater collection and distribution.
3Quantity of substance
If existing roofs are replaced with water collection systems, then rainwater can be harvested, but heavy modification or reinforcement of the framework is required
Solution Approach 1:
The water collection system is divided into discrete, pre-fabricated roofing elements that can be installed as individual units on existing roofs. Each element includes its own container and connector system, allowing for modular installation without requiring extensive framework modification. This segmentation enables the system to be applied to existing buildings with minimal structural intervention, maintaining installation simplicity while achieving effective rainwater collection.
Solution Approach 2:
The receptacle serves as an intermediary component between the roof framework and the container. It provides a standardized mounting interface that facilitates easy attachment to existing roof structures without requiring direct structural reinforcement. The receptacle acts as a mediator that adapts the container system to existing architectural constraints, enabling rainwater collection capability to be added with minimal modification to the building framework.

Function Achieved in This Case
Enables easy installation, efficient rainwater harvesting, and reduces flooding impact while maintaining the appearance of existing roofs without significant structural changes.
Implementation Method 1
Each water inlet orifice of the container is adapted to permit the rainwater falling and trickling over the surface of said roof to pass into the inside of the container
Implementation Method 2
each container comprises at least one connector adapted to be able to be connected to at least one connector of a separate container of a separate roofing element so as to enable a flow of the water between said containers
