Solution Overview

Problem

Conventional security systems are immobile and ineffective for providing security when individuals travel, as they are designed for specific locations and do not offer protection against unauthorized entry in new or unfamiliar environments.

Innovation Solution

A mobile security system that integrates electronic devices, such as cell phones, with detection systems like motion, heat, light, and vibration sensors, allowing for the detection of intruders and autonomous communication of alarms to a central monitoring system or authorities, enabling secure setup in various locations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional alarm system is installed in a specific location (home or office), then detection capability is improved, but mobility is lost and the system becomes ineffective for travel

Engineering Contradiction:

Improvedetection capabilityVSAvoidmobility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The alarm system is designed to function in multiple locations including homes, offices, and temporary accommodations during travel. The system integrates with mobile devices and uses wireless communication to provide detection capabilities across different environments, making it universally applicable rather than location-specific

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system transitions from a static, fixed-location alarm to a dynamic, portable security solution. The alarm device can be moved between locations and integrates with mobile phones that provide continuous connectivity, allowing the system to adapt to changing locations while maintaining detection and communication capabilities

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a mobile security device is used during travel, then adaptability to different locations is improved, but detection reliability may be reduced due to environmental uncertainties

Engineering Contradiction:

ImproveportabilityVSAvoiddetection reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system incorporates multiple sensors (motion, heat, light, vibration) that continuously monitor environmental conditions and provide feedback to the control system. This allows the alarm to distinguish between normal environmental variations and actual intrusion attempts, maintaining detection reliability in diverse travel locations

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The security system uses a composite approach by integrating multiple detection technologies (motion sensors, heat sensors, light sensors, vibration sensors) into a single unified system. This multi-sensor fusion compensates for individual sensor limitations and maintains reliable detection across varying environmental conditions encountered during travel

Inventive Principle:

Principle #40Composite materials

3Reliability

If multiple detection sensors are integrated into the mobile device, then detection capability is improved, but device complexity increases

Engineering Contradiction:

Improvedetection capabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Multiple detection sensors (motion, heat, light, vibration) are merged into a single integrated alarm device that communicates with the mobile phone through a unified wireless interface. This consolidation reduces the complexity of having separate systems while maintaining comprehensive detection capabilities across multiple sensor types

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A mobile security system is described herein. A detector communicates with a mobile device if an event has occurred. The event may be various types of events, such as fire or motion. Once the mobile device receives the communication of the event occurrence, the mobile device may, among others, sound an alarm or communicate with a central monitoring system to notify emergency services of the occurrence. The mobile device may also communicate with another communication device, such as another cell phone or a computer, using various forms of communication. The detector may be an integral part of the mobile device, i.e. fixed part of the mobile device, or may be detachable. The detector may also be wholly separate.
