Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containment systems for hazardous materials often fail to prevent leaks or spills from contaminating the ground, leading to environmental and regulatory issues.
Innovation Solution
A portable containment system featuring a floor made of fabric with shape memory material walls, coated with a liquid-impervious material, allowing for flexible and easy deployment and transport, without the need for metallic supports, to retain liquids and prevent material absorption into the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rigid containment structures are used, then structural strength and leak prevention are improved, but portability and ease of transport deteriorate
Solution Approach 1:
The containment structure uses flexible fabric walls coated with liquid-impervious material instead of rigid walls. The fabric material allows the structure to be folded and transported easily while the liquid-impervious coating maintains containment integrity and prevents leaks during use.
Solution Approach 2:
The containment structure transitions from a static rigid form to a dynamic flexible form that can be collapsed for transport and expanded for use. The flexible walls can be folded against each other during transport and then deployed to form the containment structure when needed.
2Ease of operation
If fabric material is used for the floor, then portability and flexibility are improved, but liquid impermeability deteriorates
Solution Approach 1:
The floor is constructed as a composite material system combining fabric substrate with liquid-impervious coating. The fabric provides flexibility and structural integrity while the liquid-impervious coating layer prevents liquid penetration, creating a material that exhibits both flexible and impermeable properties simultaneously.
Solution Approach 2:
The liquid-impervious coating changes the surface properties of the fabric material by applying a coating layer with different physical and chemical properties. This coating modifies the fabric's permeability parameter while retaining its flexibility, transforming it from a permeable to an impermeable material.
3Stability of the object's composition
If shape memory material is used for walls, then structural stability is improved, but device complexity increases
Solution Approach 1:
The shape memory material in the walls provides automatic structural support and stability without requiring external frameworks or additional support structures. The material itself generates the necessary structural integrity through its shape memory properties, eliminating the need for complex supporting elements.

AI summary
An apparatus includes a containment structure having a floor and one or more free-standing flexible walls extending along an outer perimeter of the floor and surrounding a central portion of the floor. The floor includes one or more pieces of fabric, and each free-standing flexible wall includes one or more pieces of shape memory material and extending above the floor. The one or more pieces of shape memory material are attached to the one or more pieces of fabric via a liquid-impervious material applied to the one or more pieces of fabric along the outer perimeter of the floor. The liquid-impervious material is located on the one or more pieces of fabric and the one or more pieces of shape memory material such that the floor and the one or more free-standing flexible walls are liquid-impervious and define a space configured to retain liquid in the containment structure.
