Solution Overview

Problem

Purse-related thefts, including the theft of items inside a purse or the purse itself, are common occurrences in various public places, and existing solutions do not effectively prevent undesired removals.

Innovation Solution

A purse theft deterrent system comprising a security rail integrated into the purse cavity and an external anchoring member, along with a flexible tether, secures items within the purse to the purse or to a stationary object, preventing unauthorized removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If items are placed freely in a purse, then ease of access and convenience are improved, but vulnerability to theft increases

Engineering Contradiction:
Improveease of accessVSAvoidtheft vulnerability
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The security system is divided into separate functional components: a rigid security rail integrated into the purse structure, flexible tethers for attaching items, and external anchoring members. This segmentation allows the security function to be added without fundamentally changing the purse's basic structure or item accessibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The security rail acts as an intermediary structure between the purse cavity and the items contained within. The rail provides attachment points for tethers that connect to items, creating a mechanical linkage that secures items without preventing their removal by authorized users who know how to access the tether mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a security system is added to the purse, then theft prevention is improved, but device complexity increases

Engineering Contradiction:
Improvetheft preventionVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The security rail is merged with the purse structure, integrating the security function into the existing purse design rather than adding a separate, complex security device. The rail utilizes the purse's existing cavity space and structural elements, combining security functionality with the purse's basic form.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The security rail serves multiple functions: it provides structural reinforcement to the purse, creates attachment points for securing items, and offers anchoring locations for tethers. This multi-functionality reduces the need for additional separate security components, thereby limiting the increase in overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If items are securely attached to the purse, then theft deterrence is improved, but ease of legitimate access deteriorates

Engineering Contradiction:
Improvetheft deterrenceVSAvoidlegitimate access
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The tether system employs dynamic, flexible connections rather than rigid fixed attachments. The tethers can be easily manipulated, detached, and reattached by authorized users, allowing legitimate access to remain simple while still providing security against theft. The flexible nature of the tethers enables quick adjustment and removal by users who need to access their items.

Inventive Principle:
Principle #15Dynamics

AI summary

A purse theft deterrent system for preventing undesired removal of items from a purse or the purse itself has a purse with a security rail located at least partially in a purse cavity. The system has an external independent anchoring member for use as a base of attachment for securing the purse with a flexible tether. A first tether end is located on a wallet, a pouch, or other item placed in a purse. A second tether end is located on the security rail for securing the wallet, the pouch, or other item placed in a purse to the purse via the security rail. A first tether end is located on the purse and a second tether end is attached on the anchoring member for securing the purse to the anchoring member.
