Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If diapers are stored in a bag or primary box, then diapers are readily accessible, but diapers tumble to the floor causing mess and hygiene issues

Engineering Contradiction:

Improvediaper accessVSAvoidcontamination risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The diaper package is segmented into individual diapers that are separately accessible through a dispensing slot. Each diaper is individually wrapped or separated, allowing one diaper to be retrieved at a time without exposing the entire package, thus preventing tumbling and contamination while maintaining ease of access.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If conventional diaper packages are used, then diapers are easily accessible, but they take up ample space in the room

Engineering Contradiction:

Improvediaper accessVSAvoidstorage space

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The dispenser employs a nested structure where multiple layers of diapers are stacked vertically within a compact housing. The diapers are arranged in a space-efficient configuration with each layer nested within the vertical space of the dispenser, significantly reducing the horizontal footprint while maintaining easy access through the front dispensing slot.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Productivity

If multiple diapers are accessed from a single package, then convenience is improved, but the risk of diapers falling and creating mess increases

Engineering Contradiction:

Improvediaper retrieval efficiencyVSAvoidmess creation

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The dispenser extracts and dispenses one diaper at a time through a controlled opening. The mechanical design ensures that only the topmost diaper can be removed, preventing multiple diapers from being accidentally pulled out and tumbling to the floor. This extraction mechanism maintains retrieval efficiency while eliminating the mess problem.

Inventive Principle:

Principle #2Taking out (Extraction)
