Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional packaging containers are used, then structural integrity is maintained, but ease of access to contents deteriorates

Engineering Contradiction:

Improveease of access to contentsVSAvoidstructural integrity

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The packaging container is divided into multiple peelable strips that can be individually removed. Each strip is defined by perforation lines that allow clean separation, enabling progressive access to contents while maintaining the structural integrity of the remaining container body.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The topmost peelable strip is extracted and removed from the container body to provide access to contents. This extracted strip can then be replaced with a replacement cap, allowing the container to be resealed and reused.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If peelable strips are added to enable access, then ease of operation improves, but device complexity worsens

Engineering Contradiction:

Improveease of access to contentsVSAvoidpackage structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The perforation lines are integrated directly into the container body during manufacturing, combining the sealing function and the peeling function into a single unified structure. This eliminates the need for separate peeling mechanisms or additional components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The peelable strips serve multiple functions: they seal the container, provide easy access to contents, and can be replaced with a replacement cap to restore sealing. This multi-functionality reduces the need for separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If sustainable materials are used, then environmental sustainability improves, but manufacturing precision may worsen

Engineering Contradiction:

Improveenvironmental sustainabilityVSAvoidperforation line precision

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The perforation lines are created using standard manufacturing processes that work effectively with sustainable materials. By optimizing the parameters of existing processes rather than introducing new complex techniques, manufacturing precision is maintained while using environmentally friendly materials.

Inventive Principle:

Principle #35Parameter changes
