Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Urban farms face challenges in developing reliable and economical irrigation systems, as conventional water management solutions are often costly, space-consuming, and unsuitable for urban environments, and current water containment systems are cumbersome and difficult to relocate.
Innovation Solution
A mobile fabric water tower system that employs expandable membranes for water collection, storage, and distribution, providing a lightweight, deployable, and visually appealing solution for urban farming, comprising a catchment system, water mattress system, elevated storage system, and distribution system, which is integrated with existing building structures and designed for easy relocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional water containment systems (industrial cisterns, retention ponds, static sacks, tanks) are used, then water storage capacity is achieved, but the systems become space-consuming, difficult to move, and visually deficient in urban contexts
Solution Approach 1:
The water tower employs a dynamic, collapsible fabric structure that can be easily assembled and disassembled. The fabric panels are designed to collapse when empty and expand when filled, transforming the system from a static, permanent structure to a dynamic, temporary installation that can be relocated as needed.
Solution Approach 2:
The invention uses flexible fabric panels instead of rigid conventional tanks. These thin film structures provide water containment while being lightweight, collapsible, and easy to transport. The fabric material allows the tower to be compressed to a small package for storage and movement, then expanded at the desired location.
2Quantity of substance
If conventional water containment systems are used, then water storage is achieved, but the systems are cumbersome and immobile when full
Solution Approach 1:
The system transitions from a static, heavy structure to a dynamic, adaptable form. When full, the fabric tower maintains its shape through water pressure rather than rigid support structures, allowing it to be moved by tilting or rolling the entire assembly rather than attempting to lift heavy rigid tanks.
Solution Approach 2:
The flexible fabric construction replaces heavy rigid walls with thin, lightweight material. The fabric panels are held taut by water pressure, creating a rigid-like containment structure when full, yet remaining lightweight and easy to relocate by distributing the weight across multiple panels and support points.
3Reliability
If urban farms tap into city drinking water supply, then reliable irrigation water is provided, but the solution becomes economically unfeasible due to integrated sewage treatment and water distribution costs
Solution Approach 1:
The system enables urban farms to serve their own water needs by collecting and storing rainwater on-site. The fabric tower acts as a self-contained water reservoir that captures precipitation during wet periods and provides irrigation during dry periods, eliminating dependence on expensive municipal water supplies.
Solution Approach 2:
The invention extracts the water storage function from the municipal infrastructure and places it directly at the urban farm site. By removing the need to connect to city water and sewage systems, the system eliminates the associated treatment and distribution costs while maintaining reliable irrigation supply.
4Quantity of substance
If conventional catchment surfaces (rooftop materials, pavements, painted patios) are used, then rainwater collection is achieved, but the surfaces risk contaminating the local food supply due to slight acidity of urban rainwater
Solution Approach 1:
The fabric tower employs specialized impermeable membrane material that acts as a protective barrier between collected rainwater and the underlying catchment surface. This thin film lining prevents chemical interactions and contamination while allowing the structure to remain lightweight and flexible.
Solution Approach 2:
The fabric membrane serves as an intermediary layer between the catchment surface and the water storage interior. This barrier material prevents direct contact between potentially contaminated rainwater and the food production systems, while still allowing effective water collection and storage.
