Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing backpacks do not have an integral raincoat that prevents misplacement after use and protects contents from wetting during rain.

Innovation Solution

A backpack with an integral raincoat attached via a strap, deployable from and stowable within the backpack, featuring a central opening and zipper for easy access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate raincoat is carried with the backpack, then the user can protect themselves from rain, but the user may lose or misplace the raincoat after use

Engineering Contradiction:

Improveraincoat retentionVSAvoidseparate raincoat management

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The raincoat is permanently attached to the backpack via a strap, merging two previously separate items (backpack and raincoat) into a single integrated unit. This eliminates the risk of losing the raincoat while maintaining the ability to deploy it when needed.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The raincoat is stored within the backpack when not in use, with the strap allowing it to be nested inside the bag. This nesting arrangement ensures the raincoat remains with the backpack without requiring separate management.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If the raincoat is stored inside the backpack, then the backpack contents are protected from wetting, but the raincoat cannot be easily deployed during rain

Engineering Contradiction:

Improveraincoat deploymentVSAvoidprotection of backpack contents

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The strap connecting the raincoat to the backpack is designed to be movable and adjustable, allowing the raincoat to be quickly deployed from the backpack when needed. This dynamic connection enables rapid transition between stored and deployed states.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The raincoat is pre-positioned within the backpack, ready for immediate deployment. The strap is pre-configured to allow quick release and attachment, enabling the user to deploy the raincoat instantly when precipitation occurs without delay.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If a permanent attachment system is used for the raincoat, then the raincoat cannot be lost, but the attachment mechanism becomes more complex

Engineering Contradiction:

Improveraincoat attachment securityVSAvoidattachment mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The attachment system is divided into simple, discrete components: a strap with attachment points on both the backpack and raincoat. This segmented design achieves secure permanent attachment without requiring complex mechanisms, using basic fastening elements that are easy to understand and operate.

Inventive Principle:

Principle #1Segmentation
