The current methods for customizing carpet and rug underlayment sizing are inefficient and costly, with manufacturers facing challenges in economies of scale and consumers incurring additional installation costs due to the need for on-site trimming.
Innovation Solution
A perforating device with a blade assembly and cylindrical anvil, driven by a motor, that makes parallel perforating cuts in textile materials, allowing for customizable sizing without specialized tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If underlayment is manufactured in standard sizes, then economies of scale are achieved and manufacturing costs are reduced, but consumers incur additional installation costs and time for on-site trimming
Solution Approach 1:
The patent applies preliminary action by pre-perforating the underlayment material during manufacturing in standard sizes. These perforations are placed at predetermined intervals and positions, enabling consumers to easily tear the material to custom sizes during installation without requiring specialized cutting tools. This resolves the contradiction by maintaining manufacturing efficiency while dramatically improving installation convenience.
2Ease of operation
If underlayment is custom-sized for each project, then installation convenience and precision are improved, but manufacturing costs and complexity increase due to loss of economies of scale
Solution Approach 1:
The patent applies preliminary action by pre-perforating the underlayment material during manufacturing in standard sizes. These perforations are placed at predetermined intervals and positions, enabling consumers to easily tear the material to custom sizes during installation without requiring specialized cutting tools. This resolves the contradiction by maintaining manufacturing efficiency while dramatically improving installation convenience.
3Adaptability or versatility
If underlayment is trimmed on-site using free-hand tools, then customization is achieved, but installation time increases and straight lines are difficult to maintain
Solution Approach 1:
The patent applies preliminary action by pre-perforating the underlayment material during manufacturing in standard sizes. These perforations are placed at predetermined intervals and positions, enabling consumers to easily tear the material to custom sizes during installation without requiring specialized cutting tools. This resolves the contradiction by maintaining manufacturing efficiency while dramatically improving installation convenience.
4Quantity of substance
If standard-sized underlayment is ordered in bulk, then material cost per area is reduced, but hidden costs arise from trimming requirements and potential material waste
Solution Approach 1:
The patent applies preliminary action by pre-perforating the underlayment material during manufacturing in standard sizes. These perforations are placed at predetermined intervals and positions, enabling consumers to easily tear the material to custom sizes during installation without requiring specialized cutting tools. This resolves the contradiction by maintaining manufacturing efficiency while dramatically improving installation convenience.
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
Enables on-site customization of underlayment sizing efficiently, reducing material and installation costs while maintaining precision and ease of use.
Implementation Method 1
a shaft that can be coupled to a motor that drives rotation of the shaft and the annular blades
Implementation Method 2
the outer edge of the teeth of the blades in the blade assembly contact the outer surface of the cylindrical anvil when rotating
Implementation Method 3
the blades include alternating teeth and gaps so that, when rotated, the spaced annular blades can make a plurality of parallel perforating cuts

AI summary
Described herein are examples of a perforating device for perforating a textile material, such as carpet or textile underlayment. In an example, the perforating device includes a multi-blade assembly rotationally driven by a motor. The blade assembly can be coupled to a rotary shaft such that the blades rotate with the shaft. The blades can include alternating teeth and gaps on their outer edges to create a plurality of parallel perforated cuts. Spacers can be positioned between the blades to separate them a predetermined distance. An anvil can be positioned below and adjacent the blade edges such that the teeth of the blades touch or nearly touch the anvil surface. The perforating cuts produce a textile that can be customized in terms of its size and shape at an installation site by hand, and without the need for any specialized tools or equipment.
