Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing security mechanisms for electronic merchandise on display, such as tethers and security tags, can restrict consumer evaluation while attempting to deter theft, and they may not effectively address false alarms.

Innovation Solution

A multi-alarm monitoring system that includes a transmitter, a sensor attached to the electronic device, and an alarm controller. The system generates a security event notification based on signal detection, triggering a plurality of alarms including an audible and message alarm, and can initiate a user interface lock on the electronic device. The alarm controller can operate in silent mode and automatically deactivate alarms upon correction of a security event.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a security mechanism (tether or security tag) is used to deter theft, then theft deterrence is improved, but consumer evaluation of the product is restricted

Engineering Contradiction:

Improvetheft deterrenceVSAvoidconsumer evaluation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces mechanical security mechanisms (tethers, security tags) with an electronic monitoring system using transmitters, sensors, and alarm controllers. This substitution allows consumers to freely handle and evaluate electronic devices without physical restrictions, while the electronic sensor continuously monitors for theft attempts through signal detection.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary alarm controller that acts as a mediator between the sensor detection and the alarm response. The controller processes sensor signals, determines whether theft or false alarm conditions exist, and selectively triggers appropriate responses (audible alarm, silent mode, or both), thereby balancing security enforcement with consumer evaluation needs.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If an audible alarm is generated upon security event notification, then theft deterrence is improved, but false alarm impact increases

Engineering Contradiction:

Improvetheft deterrenceVSAvoidfalse alarm impact

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements dynamic alarm response where the alarm controller adjusts the alarm behavior based on the type of security event detected. For theft events, both audible and message alarms are generated; for false alarm conditions, only the message alarm is sent and the audible alarm is suppressed. This dynamic adjustment reduces false alarm impact while maintaining theft deterrence.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the alarm system's operational parameters based on the security event type. The alarm controller modifies the alarm state (silent mode vs. active alarm) and selectively activates different alarm components (audible vs. message only) based on whether the detected event represents actual theft or a false alarm condition, thereby optimizing the response to minimize harmful effects.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If a security device allows product inspection, then consumer evaluation is improved, but security effectiveness is reduced

Engineering Contradiction:

Improveproduct inspectionVSAvoidsecurity effectiveness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces mechanical security restrictions (tethers, security tags) with an electronic monitoring system that uses transmitters and sensors to detect theft attempts. This allows consumers to freely inspect and handle electronic devices without physical constraints, while the electronic sensor continuously monitors for unauthorized removal or theft conditions, maintaining security effectiveness without compromising product inspection.

AI summary

A system for security monitoring of an electronic device on retail display includes a transmitter configured to transmit a signal, a sensor configured for attachment to the electronic device, the sensor being configured to generate a security event notification based on whether the signal is detected by the sensor, and an alarm controller configured to generate a plurality of alarms upon receipt of the security event notification from the sensor, the plurality of alarms including an audible alarm and a message alarm. The alarm controller is further configured to send the message alarm to initiate a user interface lock on the electronic device in response to the message alarm. The alarm controller is configured to operate in a silent mode in which the audible alarm is not generated upon receipt of the security event notification.
