Drain Cover With Tacky Sealing Layer for Spill Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for temporarily sealing drains are cumbersome, time-consuming, and lack reusability and transportability, especially for larger drains, and fail to provide a reliable seal against shear forces and harsh liquids.
Innovation Solution
A protective cover with a durable backing layer and a pliable, tacky sealing layer that adheres to the surrounding surface, providing a reliable seal for drains of various sizes and resisting harsh liquids, and is designed for quick implementation and easy transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If uniformly thick sheets of polyurethane or vinyl are used to cover drains, then reusability and transportability are improved, but for larger drains (30×30 inches and above), the sheets become heavy and difficult to transport and implement
Solution Approach 1:
The cover is divided into a modular system consisting of a lightweight backing layer and separate adhesive layers that can be applied as needed. This segmentation allows the main cover body to remain lightweight and easily transportable while still providing effective sealing when deployed.
Solution Approach 2:
The adhesive properties are concentrated specifically at the peripheral edges where sealing is needed, rather than distributing material uniformly across the entire cover surface. This local concentration of functionality reduces overall material usage and weight while maintaining sealing effectiveness.
2Reliability
If custom fitted ridged covers or cutoff valves are used, then sealing effectiveness is improved, but extensive preparation and installation efforts are required, and they cannot be easily adapted for other drains
Solution Approach 1:
The cover design with adhesive peripheral edges provides a universal solution that can be adapted to various drain sizes and configurations without requiring custom fabrication. The same basic design principles apply across different applications, enabling quick deployment without extensive preparation.
Solution Approach 2:
The adhesive layers are pre-applied to the backing layer during manufacturing, eliminating the need for on-site preparation and installation efforts. This preliminary action ensures the cover is ready for immediate deployment when needed.
3Ease of manufacture
If flexible material held in place by dirt or sand is used to seal off a drain, then implementation is possible, but the covering is difficult to work with, cumbersome, and the seal has limited resistance to shear forces of onrushing liquids
Solution Approach 1:
The mechanical system of using dirt or sand to hold flexible material in place is replaced with an adhesive chemical bonding system. The adhesive layers provide secure attachment to the drain surface, eliminating the need for external weighting materials and providing superior resistance to shear forces from onrushing liquids.

Function Achieved in This Case
The solution effectively prevents spills from entering drains, is lightweight and reusable, and can be easily implemented in emergency situations, even for large drains, with a durable and flexible design that withstands industrial vehicle traffic and harsh environments.
Implementation Method 1
a pliable, tacky sealing layer adjacent the backing layer such that it may adhere to a surface surrounding the drain to prevent the flow of liquid therebetween

AI summary
A protective cover for drains and other holes is provided which prevents spills and unwanted liquids from flowing therein. The protective cover includes a durable backing layer and a pliable, tacky sealing layer adjacent a portion of the durable backing layer which conforms and adheres to a surface surrounding the drain to reduce or eliminate the flow of liquids into the drain. The pliable, tacky sealing layer can have a periphery inside the periphery of the durable backing layer.
