Solution Overview

Problem

Existing mobile device security systems require upgrades to cradles and do not effectively prevent theft, as users can walk off with devices once released, leading to increased costs and risks of loss or theft.

Innovation Solution

A system and method that securely allocates mobile devices by storing them in an inoperative state under host computer control, using identification codes to activate devices and secure areas, with alarms and data purging features to deter theft and ensure secure operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical locking mechanisms are used in cradles to secure mobile devices, then device security is improved, but device complexity and cost increase due to required cradle upgrades

Engineering Contradiction:
Improvedevice securityVSAvoidcradle complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces mechanical locking mechanisms with an electronic/software-based solution. The host computer controls the operational state of mobile devices through software, enabling security without physical locks. This substitution eliminates the need for complex mechanical cradles while maintaining security through centralized electronic control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The host computer acts as an intermediary between the user and the mobile device. Instead of direct physical access or mechanical locking, the host computer mediates device access by controlling operational states based on authorization, thereby securing devices without requiring modified cradles.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If physical locking mechanisms are used in cradles to secure mobile devices, then device security is improved, but loss prevention is worsened as devices can still be stolen once released

Engineering Contradiction:
Improvedevice securityVSAvoidtheft risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by controlling the operational state of devices before they are accessed. Devices are kept in an inoperative state until authorized, and the system can immediately render them inoperable again upon return. This preliminary control prevents theft by ensuring devices cannot function even if physically removed, eliminating the vulnerability window present in mechanical locking systems.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The electronic control system replaces mechanical locking, providing continuous security control rather than intermittent physical restraint. The host computer can instantly change device operational states, creating a more effective barrier against theft compared to mechanical locks that can be bypassed or picked.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If mobile devices are made smaller and lighter to increase portability, then ease of transport is improved, but security is worsened due to increased likelihood of misplacement and theft

Engineering Contradiction:
ImproveportabilityVSAvoiddevice security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces physical security measures with electronic control, allowing secure management of small, portable devices without adding bulk. The host computer-based system provides security through software control rather than physical constraints, maintaining the devices' portability while enhancing security capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The mobile devices themselves participate in the security system by communicating their operational state and location to the host computer. This self-service capability allows the system to monitor and control devices remotely, providing security proportional to device size rather than requiring proportional physical security measures.

Inventive Principle:
Principle #25Self-service

AI summary

A system and method of securely allocating mobile devices is disclosed. A plurality of mobile devices are stored in an inoperative state under the control of a host computer. A user enters an identification code, which is received by the host computer, and the host computer selectively places a mobile device in an operative state based on the identification code. If the selected mobile device is not returned within a first predetermined interval, then the selected mobile device is placed back in the inoperative state. If the selected mobile device is not returned within a second predetermined interval, then all data within the selected mobile device's memory is purged. Additionally, the plurality of mobile devices can be stored in a secure area. Access to the secure area is granted based on the identification code.
