Solution Overview

Problem

Conventional methods for cutting tinted films for vehicle windows are inefficient due to the need for multiple guide frames for various vehicles, manual cutting of complex shapes leading to worker fatigue, and contamination issues during the cutting process.

Innovation Solution

An apparatus with a tilted cutting-line displaying plate, a contaminant remover, and a cutting-line formation device that uses a display panel or beam projector to indicate cutting lines, along with a static-electricity based dust absorber and liquid sprayer to prevent dust deposition, allowing for automated cutting and continuous production of tinted films for different vehicle types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional guide frame is used for cutting tinted films, then various types of vehicle films can be cut, but a large amount of guide frames must be stored and production efficiency is lowered

Engineering Contradiction:

Improveability to cut various vehicle film typesVSAvoidproduction efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent replaces physical guide frames with a display panel that projects virtual cutting lines. The display panel displays different cutting patterns for various vehicle types without requiring physical frame changes, thus maintaining versatility while eliminating the need to store multiple guide frames

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent substitutes the mechanical guide frame system with an electronic display system. The display panel, controlled by a controller, projects cutting lines directly onto the tinted film, replacing the need for physical guide frames and manual positioning

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If manual cutting of various film shapes is performed, then different vehicle glass shapes can be accommodated, but worker fatigue is increased and work efficiency is lowered

Engineering Contradiction:

Improveability to cut various film shapesVSAvoidworker fatigue

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system allows operators to select cutting patterns from pre-stored data corresponding to different vehicle types. The controller automatically retrieves and displays the appropriate cutting line, eliminating the need for manual measurement and complex manual cutting operations

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual cutting operations with automated cutting devices that follow the projected cutting lines from the display panel, reducing worker fatigue while maintaining the ability to cut various film shapes

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If cutting operation is performed without dust protection, then the process is simple, but dust sticks to the film causing contamination issues

Engineering Contradiction:

Improvesimplicity of cutting processVSAvoiddust contamination on film

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a dust-removing device as an intermediary between the cutting environment and the tinted film. This device eliminates dust particles from the cutting area, protecting the film from contamination while maintaining process simplicity

Inventive Principle:

Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
