Solution Overview

Problem

There is no standardized method to measure the lip sticking force of tipping paper for cigarettes, leading to inconsistent quality and consumer discomfort, as existing methods rely on subjective sensory evaluations without objective standards.

Innovation Solution

A test system comprising an artificial lip and specialized equipment, including a friction meter testing platform, force measuring sensor, and pulley system, along with artificial saliva, to objectively measure the lip sticking force of tipping paper, using a silica gel block or 3M low-viscosity tape as the artificial lip and recording the maximum force at separation to classify the sticking force grade.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If artificial sensory evaluation is used to determine lip sticking force, then the test can be performed without specialized equipment, but the test results show big differences and lack objectivity

Engineering Contradiction:

Improvetest equipmentVSAvoidlip sticking force measurement

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent creates an artificial lip that copies the physical and chemical properties of human lips, including the lip surface layer, lip muscle layer, and lip mucosa layer. This artificial model allows objective measurement of lip sticking force without requiring actual human subjects, thereby improving measurement precision while maintaining relatively simple test equipment requirements.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent introduces artificial saliva as an intermediary substance that simulates the binding effect of real saliva between the tipping paper and the lip. This mediator enables the measurement of lip sticking force in a controlled environment, transforming a subjective sensory evaluation into an objective mechanical measurement.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If no standardized test method is established, then the quality control process remains flexible and adaptable, but the test results show big differences between evaluations

Engineering Contradiction:

Improvequality control flexibilityVSAvoidtest result consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent establishes specific test parameters including the composition of artificial saliva, the structure of artificial lip layers, the loading rate of 50mm/min, and the contact time of 5-6 seconds. These standardized parameters ensure consistent and reliable test results across different evaluations while maintaining the flexibility to adjust parameters for different tipping paper specifications.

Inventive Principle:

Principle #35Parameter changes

3Strength

If tipping paper with high lip sticking force is used, then the decorative effect and bond strength are improved, but the tipping paper sticks to the lips causing discomfort and potential injury

Engineering Contradiction:

Improvebond strengthVSAvoidlip sticking discomfort

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the complex biological interaction between real saliva and human lip tissue with a simplified mechanical measurement system. By using artificial saliva and an artificial lip model, the system can objectively measure bond strength and lip sticking force separately, allowing optimization of tipping paper properties to achieve adequate bond strength while minimizing harmful lip sticking effects.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
