Modular Catch Mat with Resilient Masking Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drop cloths used in construction projects are difficult to use due to their tendency to bend and bunch up, leaving exposed areas, posing tripping hazards and making it hard to protect floors and walls effectively, and are cumbersome to store and clean.
Innovation Solution
A catch mat composed of cushioning pads with two-part fastener strips and resilient masking strips that can be easily configured to fit against walls, forming a seal to catch debris and paint, and can be easily folded, transported, and stored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If thin fabric or plastic drop cloths are used, then they are lightweight and easy to transport, but they bend and bunch-up leaving portions of the floor and wall exposed
Solution Approach 1:
The drop cloth is divided into multiple rigid panels that can be connected together. Each panel maintains its own shape and provides stable protection, while the modular structure allows the system to adapt to different wall sizes and configurations without bending or bunching up.
Solution Approach 2:
Different portions of the wall receive different levels of protection based on their specific needs. The rigid panels can be strategically positioned to provide enhanced protection at corners and high-traffic areas, while maintaining overall coverage across the entire wall surface.
2Ease of operation
If thin fabric or plastic drop cloths are used, then they are easy to unfold, but they require taping to keep them against the wall
Solution Approach 1:
The connection between panels and the attachment to the wall are combined into a single integrated mechanism. The magnetic fastening system simultaneously joins panels together and secures the entire assembly to the wall surface, eliminating the need for separate taping operations.
Solution Approach 2:
Traditional mechanical fastening methods (tapes, adhesives, clips) are replaced with a magnetic attachment system. The magnetic force provides sufficient holding power to keep the rigid panels against the wall without requiring additional fastening materials, simplifying the deployment process.
3Reliability
If drop cloths are used to protect floors and walls, then debris is caught, but dumping the debris is messy and difficult
Solution Approach 1:
The rigid panel structure allows for easy removal and disposal of collected debris. Panels can be detached from the wall, shaken out, or rinsed clean, and then reattached for continued use. This recoverable design eliminates the mess and difficulty associated with traditional drop cloth debris removal.
4Reliability
If traditional drop cloths are used, then they provide floor protection, but folding or rolling them for storage takes an inordinate amount of time
Solution Approach 1:
The protective covering is segmented into rigid panels that can be easily detached and stacked. After use, panels are simply removed from the wall and stored in a compact stack, eliminating the time-consuming folding and rolling operations required for traditional flexible drop cloths.
5Weight of moving object
If thin drop cloths are used, then they are light-weight, but they present tripping hazards when bunched-up
Solution Approach 1:
Instead of allowing the drop cloth to bunch up on the floor (creating tripping hazards), the system inverts the approach by using rigid panels that maintain a fixed, stable position against the wall. The panels are positioned to extend slightly beyond the wall base, creating a barrier that prevents debris from reaching the floor while eliminating tripping hazards.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The catch mat effectively protects floors and walls from debris and paint during construction activities, is easy to use and clean, and facilitates efficient storage and transport, reducing the risk of damage and tripping hazards.
Implementation Method 1
Each resilient masking strip directs falling debris away from the wall, even for a time after being removed from contact with the wall while the resilient masking strip returns to its normal shape projecting away from the peripheral edge of the cushioning pad.

AI summary
A catch mat for protecting a floor and a wall during construction activities includes two or more cushioning pads each having a top surface, a bottom surface, and four peripheral edges. Each cushioning pad has a first part of a two-part fastener strip fixed along the top surface proximate one of the peripheral edges. A flexible second part of the two-part fastener strip is adapted to engage the first part of the two-part fastener strip of adjacent and abutting cushioning pads to fasten them mutually yet pivotally together. Each cushioning pad further includes at least one resilient masking strip projecting away from one of the peripheral edges of the cushioning pad at the top surface thereof. In use, the cushioning pads, fastened together, are placed on the floor against the wall with the masking strip bent upward against the wall to protect the floor and wall from falling debris.
