Solution Overview

Problem

Existing devices for applying trim to textile surfaces lack the capability to simultaneously cut, fold, and adhere end pieces of the trim, resulting in an unfinished appearance.

Innovation Solution

A device that includes a material holder assembly for dispensing trim and adhesive materials, a control and heating assembly for preparing the materials, and a cutting and forming compartment with a folding mechanism and pressing mechanisms to cut, fold, and adhere the trim ends.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing devices are used to apply trim to textile surfaces, then the trim can be dispensed, but the ends remain unfinished and require separate processing steps

Engineering Contradiction:

Improvesimplicity of application processVSAvoidnumber of processing steps

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent combines cutting, folding, and adhering functions into a single integrated device and operation. The cutting mechanism cuts the trim to length, the folding mechanism folds the ends, and the pressing mechanism adheres the folded ends to the trim body, all in one continuous motion without requiring separate processing steps.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device performs multiple functions simultaneously: it dispenses trim material, cuts it to the desired length, folds the ends, and adheres the folded ends to create a finished appearance. This multi-functional approach eliminates the need for separate devices or operations for each processing step.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple separate devices are used for cutting, folding, and adhering trim ends, then each function can be performed, but the device complexity increases

Engineering Contradiction:

Improvecapability to perform multiple operationsVSAvoidnumber of components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent integrates cutting, folding, and adhering mechanisms into a single device structure. The cutting mechanism, folding mechanism, and pressing mechanism are combined in one unit that processes trim ends in a single continuous operation, reducing the number of separate components and devices needed.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

While integrating multiple functions, the device uses modular components that can be independently adjusted. The cutting mechanism, folding mechanism, and pressing mechanism are segmented into distinct functional units within the integrated device, allowing for independent adjustment and maintenance while maintaining overall integration.

Inventive Principle:

Principle #1Segmentation

3Productivity

If trim ends are not folded and adhered, then the application is faster, but the appearance is unfinished

Engineering Contradiction:

Improvespeed of applicationVSAvoidfinished appearance

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The folding and adhering actions are performed immediately after cutting in the same continuous operation, creating a finished appearance before the trim is applied to the textile. This preliminary finishing ensures that the trim ends are properly prepared and aesthetically completed before attachment.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device maintains continuous motion throughout the cutting, folding, and adhering process without stopping or requiring separate operations. The trim material moves continuously through the device, with each function performed in sequence during a single pass, maintaining both speed and quality.

Inventive Principle:

Principle #20Continuity of useful action
