Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Purses and handbags often slide off or tip over on vehicle seats during driving, causing contents to spill due to lack of securement.

Innovation Solution

A purse securing device with straps that wrap around a vehicle's headrest or rear seat and purse handles, utilizing a hook and loop fastener for secure attachment, forming a T-shape configuration to prevent sliding or tipping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If straps are added to secure the purse, then the purse stability is improved, but the device complexity increases

Engineering Contradiction:

Improvepurse stabilityVSAvoiddevice complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The securing device is divided into multiple independent straps (first strap, second strap, third strap) that can be separately attached to different parts of the purse and seat, allowing modular assembly and adjustment for optimal stability without requiring a complex integrated structure

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The straps are designed to perform multiple functions: they can be attached to the headrest, rear portion of the seat, or directly to the purse, providing versatile securing options that adapt to different purse sizes and seat configurations while maintaining simplicity

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If fabric straps are used instead of rigid materials, then the comfort for seated individuals is improved, but the securing strength may be reduced

Engineering Contradiction:

Improveseating comfortVSAvoidsecuring strength

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The device uses flexible fabric straps instead of rigid materials, allowing the straps to conform to the contours of the seat and purse while distributing pressure evenly, preventing discomfort to seated individuals while maintaining sufficient securing strength through the flexibility and tensile properties of the fabric

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The fabric straps are designed with specific width and thickness parameters that optimize both comfort and strength, creating a balance where the material properties provide adequate securing force while remaining soft and comfortable for prolonged contact with seated individuals

Inventive Principle:

Principle #35Parameter changes

AI summary

A purse securing device (1) having an upper strap (4) having a first strap (5) and a second strap (6) that wrap around a head rest (7) or rear portion (8) of the vehicle seat (2). A lower strap (9) extends vertically downward from the upper strap. When laid flat the upper strap and lower strap create a substantially T-shape. The lower strap attaches to a purse to prevent the purse from tipping over.
