Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If aerosol generating materials are integrated into a structured format with sheet material, then consistent release of volatile compounds is achieved, but manufacturing complexity increases

Engineering Contradiction:

Improveconsistent release of volatile compoundsVSAvoidmanufacturing structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The article is divided into distinct functional components: a substrate containing aerosol generating material, a first sheet material surrounding the substrate, and optionally a second sheet material. This segmentation allows each component to be optimized independently while working together to ensure consistent volatile compound release.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The substrate containing aerosol generating material is nested within the first sheet material, which is itself surrounded by a second sheet material. This nested structure ensures the aerosol generating material is contained and positioned correctly while allowing for controlled release of volatile compounds during use.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If substrate is attached to sheet material, then aerosol generating material is contained and heat transfer is enhanced, but manufacturing process complexity increases

Engineering Contradiction:

Improveaerosol generating material containmentVSAvoidattachment process

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The substrate is pre-formed with aerosol generating material before being attached to the sheet material. This preliminary preparation allows for optimized material distribution and simplifies the subsequent attachment process, as the substrate is ready-to-use and requires minimal additional processing.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

An adhesive layer is used as an intermediary between the substrate and the first sheet material, facilitating easy attachment while ensuring reliable containment of the aerosol generating material. The adhesive acts as a mediator that bonds the components together without requiring complex mechanical fastening or welding processes.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If multiple sheet materials are used to surround substrate, then aerosol release efficiency is improved, but production time increases

Engineering Contradiction:

Improveaerosol release efficiencyVSAvoidmanufacturing cycle time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The first and second sheet materials are combined to form a integrated structure that surrounds the substrate. This merging of components creates an efficient aerosol release system where the sheet materials work together to contain and direct the aerosol flow, improving release efficiency while maintaining a streamlined manufacturing process.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Thin sheet materials are used to surround the substrate, providing effective containment and aerosol release control without adding significant bulk or complexity. The thin film structure allows for rapid manufacturing while ensuring proper aerosol generation and delivery performance.

Inventive Principle:

Principle #30Flexible shells and thin films
