Cellulose Film Detectable Particle Integration

Solution Overview

Problem

Current food packaging films, particularly those based on cellulose, lack efficient detectability using economic and readily available equipment, making it difficult to ensure complete removal of packaging materials from food products, especially during processing and production.

Innovation Solution

Incorporating detectable particles into the cellulose film production process, allowing for the regeneration of cellulose films with embedded detectable particles that are detectable via metal or optical detection methods, ensuring the film's integrity and safety in industrial processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Difficulty of detecting and measuring

If detectable particles are incorporated into cellulose films, then detectability is improved, but manufacturing complexity increases

Engineering Contradiction:

ImprovedetectabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

Detectable particles are incorporated into the cellulose film during the manufacturing process itself, rather than adding detection capability later. The particles are mixed into the cellulose solution before extrusion, ensuring detectability is built into the film structure from the beginning.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The detection function is merged with the packaging film by incorporating detectable particles directly into the cellulose matrix. This combines the packaging function with the detection function in a single integrated component, eliminating the need for separate detection systems.

Inventive Principle:

Principle #5Merging (Combining)

2Difficulty of detecting and measuring

If detectable particles are added to cellulose solution, then detection capability is improved, but process complexity increases

Engineering Contradiction:

Improvedetection capabilityVSAvoidprocess simplicity

Core Design Contradiction:

Difficulty of detecting and measuringVSEase of manufacture

Solution Approach 1:

Detectable particles are incorporated into the cellulose solution during the solution preparation stage, before extrusion. This preliminary incorporation ensures particles are uniformly distributed throughout the film and eliminates the need for separate particle addition steps later in the process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The cellulose solution serves multiple functions: it acts as the base material for the film, the medium for particle distribution, and the vehicle for delivering detectable particles uniformly throughout the final product. This multi-functionality simplifies the overall manufacturing process.

Inventive Principle:

Principle #6Universality (Multi-functionality)
