Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional security tags are inefficient as they can be easily defeated by skilled thieves, who develop techniques to remove them without activating alarms or damaging the merchandise, due to widespread knowledge of their structural features.

Innovation Solution

A security system with a security tag assembly comprising a base and attachment member, featuring a connector pin and locking assembly that can be securely attached to merchandise, and a detachment assembly with a drive shaft and holding structure to facilitate authorized removal while rendering the locking assembly useless upon forced separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional security tags are used with simple attachment structures, then ease of manufacture and operation are improved, but reliability against theft is worsened because skilled thieves can easily defeat them

Engineering Contradiction:

Improvesecurity effectivenessVSAvoidtag structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The security tag is divided into separate components: a base unit and a detachable attachment member. The attachment member can be securely attached to merchandise and then detached only with proper authorization, while the base unit remains. This segmentation allows the security system to be more reliable without requiring the entire tag structure to be complex.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The attachment member is pre-configured with locking mechanisms and detachment features that enable secure attachment to merchandise before the security check process. The preliminary setup includes integrated locking assemblies and detachment structures that are ready to prevent unauthorized removal.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If secure locking mechanisms are implemented to prevent unauthorized removal, then reliability is improved, but ease of operation is worsened because authorized detachment becomes more difficult

Engineering Contradiction:

Improveprevention of unauthorized removalVSAvoidauthorized detachment ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

A detachment assembly acts as an intermediary device that facilitates authorized removal of the attachment member from the base unit. This intermediary mechanism allows authorized personnel to easily detach the attachment member using proper tools or procedures, while maintaining strong prevention against unauthorized removal.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The locking mechanism transitions from a static secure state to a dynamic release state through authorized action. The detachment assembly introduces dynamic elements that allow the locking mechanism to be intentionally opened with proper authorization, balancing security with operational ease.

Inventive Principle:

Principle #15Dynamics

3Ease of manufacture

If the attachment member is designed to be disposable after use, then ease of manufacture and cost are improved, but loss of substance is worsened due to repeated production of single-use components

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidmaterial consumption

Core Design Contradiction:

Ease of manufactureVSLoss of substance

Solution Approach 1:

The attachment member is designed as a disposable component that is inexpensive to manufacture and can be easily replaced. After use, the attachment member is discarded and a new one is attached to the next item of merchandise, simplifying the manufacturing process and maintaining security effectiveness.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

4Loss of substance

If the base unit is designed to be reusable with multiple attachment members, then loss of substance is improved by reducing waste, but device complexity is worsened due to repeated attachment and detachment cycles

Engineering Contradiction:

Improvereduction of wasteVSAvoidrepeated attachment cycles

Core Design Contradiction:

Loss of substanceVSDevice complexity

Solution Approach 1:

The base unit is designed as a universal platform that can accommodate multiple different attachment members through standardized connection interfaces. This multi-functionality allows the same base unit to be reused with various attachment members for different merchandise items, reducing waste while maintaining operational simplicity through standardization.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A security tag assembly and security system associated therewith to prevent the unauthorized removal of merchandise from a given area, such as a retail establishment. The security tag assembly comprises a base and at least one attachment member removably connected in an operative position on the merchandise being protected. A locking assembly including a locking member is structured to restrict detachment of the attachment member and is forcibly disposed out of movement restricting relation to said connector member when the base and the attachment member are separated. A detachment assembly and a data registering processor may include a two-way communication link which facilitates processing of the merchandise data disposed on the security tag assembly, such that the purchasing of the merchandise and the removal of the security tag assembly can be effectively accomplished without jeopardizing the security of the merchandise being sold.
