Solution Overview

Problem

Current die-cut manufacturing methods result in significant material waste and increased costs due to the removal of unwanted areas, which complicates the process and increases the final product price, especially when dealing with complex geometries or multiple layers.

Innovation Solution

The method involves breaking down the desired die-cut design into individual components that are assembled using computer-controlled pick and place equipment onto a target liner, eliminating the need to remove unwanted material and thus reducing waste and simplifying the manufacturing process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If traditional kiss-cutting and material removal methods are used to manufacture die-cuts, then the manufacturing process can produce standard die-cut shapes, but significant material waste occurs and production costs increase

Engineering Contradiction:

Improvematerial wasteVSAvoidmanufacturing process complexity

Core Design Contradiction:

Loss of substanceVSEase of manufacture

Solution Approach 1:

The patent divides the die-cut manufacturing process into segmentation by assembling multiple pre-cut adhesive components onto a liner rather than creating the entire die-cut as a single stamped piece. This allows each component to be precisely cut to size without generating waste from surrounding material that would need to be removed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of the traditional approach of stamping a complete die-cut design and then removing unwanted material, the patent inverts the process by first creating individual adhesive components and then assembling them to form the final die-cut shape. This eliminates the need for material removal operations.

Inventive Principle:

Principle #13The other way round (Inversion)

2Manufacturing precision

If material is removed to create unwanted area in die-cuts, then the desired geometry is achieved, but production costs increase and process complexity increases

Engineering Contradiction:

Improvedie-cut geometry precisionVSAvoidprocess steps

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-cutting adhesive components to their exact final dimensions before assembly. This eliminates the need for subsequent material removal operations to achieve the desired geometry, as each component is already precisely sized and shaped for its final position.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If traditional stamping dies are used to cut adhesive materials, then high volume production is achieved, but unwanted areas are discarded as waste

Engineering Contradiction:

Improveproduction volumeVSAvoidadhesive material waste

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

The patent segments the adhesive material usage by creating only the necessary adhesive components without generating surrounding waste material. Multiple precision-cut adhesive pieces are assembled onto a liner, ensuring that every piece of adhesive material applied serves a functional purpose in the final die-cut product.

Inventive Principle:

Principle #1Segmentation

4Adaptability or versatility

If complex geometries or multiple layers are required in die-cuts, then application functionality is improved, but manufacturing complexity and cost increase significantly

Engineering Contradiction:

Improvedie-cut geometry complexityVSAvoidmanufacturing difficulty

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent uses segmentation to manufacture complex multi-layer die-cuts by creating individual adhesive components for each layer and position, then assembling them systematically onto a liner. This modular approach simplifies the manufacturing of complex geometries compared to traditional single-step stamping, as each component can be independently cut and positioned with precision.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent adds a temporal dimension to the manufacturing process by assembling components in sequence rather than creating the entire structure in a single stamping operation. This allows complex three-dimensional die-cut structures to be built layer by layer, with each layer being independently manufactured and then assembled, thereby managing complexity more effectively.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

Methods are provided for assembling desired die-cuts from individual die-cut components. Each individual die-cut component may consist of films of various materials, diverse adhesive tapes, diverse foam materials, fabrics, metals and others. Individual die-cut components are assembled onto liners that function as carriers or platforms. The liners may be in individual panels or continuous rolls. Individual die-cut components are assembled onto the liner using computer controlled pick and place equipment with a high degree of accuracy and speed. The liner may consist of a film with controlled adhesive strength to maintain the x-y position of placed individual die-cut components. The die-cut comprising the liner and assembled die-cut components is then used for various purposes, such as holding two parts together, in the assembly of various products, such as cell phones.
