Solution Overview

Problem

Existing pouches for items like phones are inconvenient to carry due to size and lack the ability to hold multiple items simultaneously.

Innovation Solution

An inflatable pouch with an interior pocket, air valve, zipper, clasps, and adjustable rope, designed to inflate using a single chamber, providing protection and convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing pouches are made larger to hold multiple items, then the capacity to hold multiple items is improved, but the convenience of carrying deteriorates

Engineering Contradiction:

Improvecapacity to hold multiple itemsVSAvoidconvenience of carrying

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The pouch is divided into multiple separate compartments including a main compartment and an interior pocket, allowing different items to be stored separately while maintaining a compact overall structure that is easy to carry

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The interior pocket is nested within the main compartment structure, enabling the pouch to hold multiple types of items (phone in main compartment, accessories in interior pocket) without increasing the external dimensions, thus maintaining portability while expanding capacity

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If existing pouches are made larger to provide better protection, then the protective capability is improved, but the bulk and portability deteriorate

Engineering Contradiction:

Improveprotective capabilityVSAvoidbulk

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

Protection is provided locally at critical areas through the inflatable body structure and weather-proof material, rather than requiring the entire pouch to be oversized. The inflatable chambers provide targeted cushioning where needed while maintaining a compact overall form factor

Inventive Principle:

Principle #3Local quality

3Ease of operation

If a single chamber inflatable structure is used, then the ease of inflation and structural efficiency is improved, but the complexity of the design may increase

Engineering Contradiction:

Improveease of inflationVSAvoiddesign complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The single inflatable chamber serves multiple functions simultaneously: it provides structural support for the pouch shape, offers protective cushioning for contents, enables the pouch to float on water, and creates weather-proofing. This multi-functionality reduces the need for additional separate components, thereby simplifying the overall design despite the sophisticated performance requirements

Inventive Principle:

Principle #6Universality (Multi-functionality)
