Solution Overview

Problem

Current methods and tools for making customized cards are inefficient and cumbersome, particularly for home users with limited cutting machine capabilities, making it difficult to cut, inscribe, or form large or numerous customized cards with precision and accuracy.

Innovation Solution

The use of a card forming mat with an upper barrier layer and a lower layer, allowing a portion of the card to be inserted between the layers and the remaining portion folded over, enabling efficient processing in electronic cutting machines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If home electronic cutting machines are used for card making, then the card making process can be performed at home with limited equipment, but the cutting width is limited to about six or twelve inches and it takes an inconveniently long time to make large or numerous customized cards

Engineering Contradiction:
Improvecard making accessibilityVSAvoidcard making speed
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The card mat is divided into multiple layers (upper barrier layer, lower layer, and intermediate layer) that can be separated and recombined. This segmentation allows the card making process to be broken into manageable steps that can be efficiently processed by home cutting machines with limited cutting widths, while still enabling production of large or numerous cards through repeated cycles.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The card is partially formed and positioned between the layers of the card mat before being inserted into the cutting machine. This preliminary arrangement of the card portions and the mat layers prepares the workpiece in advance, allowing the cutting machine to efficiently complete the card making process without requiring manual repositioning or setup during operation.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If home electronic cutting machines are used for card making, then the card making process can be performed at home with limited equipment, but the precision and accuracy of cutting, inscribing, or forming cards is compromised

Engineering Contradiction:
Improvecard making accessibilityVSAvoidcutting precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The card mat layers act as an intermediary structure that holds the card portions in precise alignment during the cutting and inscribing processes. The upper barrier layer and lower layer provide stable reference surfaces that ensure consistent positioning, enabling home cutting machines to achieve precision and accuracy comparable to professional equipment.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If traditional card making methods are used, then simple tools are available, but the process is inefficient and cumbersome for making large or numerous customized cards

Engineering Contradiction:
Improvetool simplicityVSAvoidcard making efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The invention combines simple home cutting machines with the multi-layered card mat system to create an integrated card making process. This merging allows the use of simple, accessible equipment while achieving high productivity through the efficient workflow enabled by the card mat structure, which facilitates batch processing and reduces manual intervention.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A method inserting a first portion of a workpiece material between an upper layer and a lower layer of a workpiece support material. The method also includes folding a second portion of the workpiece material over and on top of the upper layer of the workpiece support material. The second portion is coupled to the first portion. The method further includes inserting the workpiece material and the workpiece support material into an electronic cutting machine.
