Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing tote bags and blankets are limited in their functionality, lacking the ability to seamlessly convert between the two forms, and often require separate carrying solutions when transitioning from one use to another.

Innovation Solution

A convertible tote bag that transforms into a blanket and vice versa, featuring adjustable straps, hidden magnetic snaps, and multiple pockets for versatility and convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a tote bag is designed with multiple pockets and straps for functionality, then the device complexity increases, but the ease of operation decreases when converting to blanket mode

Engineering Contradiction:

ImprovefunctionalityVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The blanket is divided into distinct functional zones: a first portion with pockets and straps for carrying items, and a second portion for seating and comfort. This segmentation allows each portion to be optimized for its specific function while simplifying the overall conversion mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first portion of the blanket serves multiple functions: it acts as a carrying bag with pockets and straps, and simultaneously provides structural support when the blanket is used for sitting. This multi-functionality reduces the need for separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a tote bag includes multiple pockets and securement features, then the manufacturing complexity increases, but the reliability of item security improves

Engineering Contradiction:

Improveitem securityVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

Multiple securement features (pockets, elastic strips, snap buttons) are integrated directly into the blanket fabric rather than being separate attachments. This merging reduces the number of discrete parts to manufacture while maintaining comprehensive item security.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Different portions of the blanket have different densities of securement features: the first portion has multiple pockets and elastic strips for item security, while the second portion has fewer features optimized for comfort. This localized differentiation reduces overall manufacturing complexity.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If the blanket is designed to convert to tote bag mode with straps and loops, then the adaptability improves, but the ease of operation decreases due to complex folding requirements

Engineering Contradiction:

ImproveconvertibilityVSAvoidconversion ease

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The belt loops and straps are pre-positioned and permanently attached to the blanket in specific locations before use. This preliminary arrangement eliminates the need for users to figure out how to configure the conversion features, simplifying the conversion process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The conversion mechanism uses flexible elastic strips and movable snap buttons that can be easily adjusted and repositioned. This dynamic design allows for quick conversion between blanket and tote bag modes without complex folding or assembly steps.

Inventive Principle:

Principle #15Dynamics

4Reliability

If the blanket includes multiple securement features like elastic strips and snap buttons, then the reliability of item retention improves, but the device complexity increases

Engineering Contradiction:

Improveitem retentionVSAvoidfeature complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Multiple securement features are nested within each other: elastic strips are enclosed by fabric channels, snap buttons are integrated into pocket structures, and belt loops are formed from the blanket material itself. This nesting reduces the visual and functional complexity while maintaining multiple retention mechanisms.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

The disclosure provides an article of manufacture that includes a body including first and second circular-shaped layers of material attached together at their outer perimeter, where the first layer and second layer are made of different materials, where the first layer comprises a series of belt loops disposed adjacent to its outer perimeter, and the second layer comprises a set of pockets disposed within and a circular strap woven within the series of belt loops having a length that permits the strap to form two loops on opposites sides of the body such that when the loops are held together, the body drops below the loops and collapses or folds inward to form a bag.
