Solution Overview

Problem

Existing vehicle alarm systems lack comprehensive and remote alerting capabilities for potential theft, particularly in detecting impacts on windows and door handle manipulations, and do not effectively deter thieves with escalating alerts and surveillance.

Innovation Solution

A vehicle security alarm system comprising window sensors, handle sensors, a motion sensing array, a surveillance unit, and a communication unit that alerts the owner via a personal electronic device, with escalating audible alerts and remote video surveillance to deter theft and facilitate immediate owner notification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple sensors (window sensors, handle sensors, motion sensing array) are integrated into the alarm system, then the detection capability and security coverage are improved, but the device complexity increases

Engineering Contradiction:

Improvedetection capabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple sensor types (window sensors, handle sensors, motion sensing array) into a single integrated alarm system that shares common control logic and alerting mechanisms. This merging approach maintains high detection capability across multiple vehicle components while reducing overall system complexity compared to separate independent systems.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The alarm system is designed as a multi-functional unit that can detect various types of threats through different sensors (impact on windows, manipulation of door handles, motion in proximity) and respond with unified alerting mechanisms. This universal design allows a single system to perform multiple security functions, improving reliability without proportionally increasing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a surveillance unit is mounted to the rear view mirror to surveil the back seat, then the monitoring coverage is improved, but the device complexity and installation difficulty increase

Engineering Contradiction:

Improvemonitoring coverageVSAvoidinstallation difficulty

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The surveillance unit is pre-mounted to the rear view mirror assembly, which is a standard component in most vehicles. This preliminary positioning allows the camera to achieve optimal surveillance coverage of the back seat area without requiring complex custom installation procedures, thereby improving monitoring coverage while minimizing installation difficulty.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If escalating audible alerts and remote notification features are added, then the deterrent effect and owner notification capability are improved, but the use of energy increases

Engineering Contradiction:

Improvedeterrent effectVSAvoiduse of energy

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The alarm system employs escalating audible alerts that activate in periodic stages: initially a first audible alert is triggered, and if the threat persists, a second audible alert with different characteristics is activated. This periodic escalation maintains an effective deterrent effect while managing energy consumption by not sustaining maximum alert intensity continuously.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system uses a communication unit as an intermediary to send notifications to the owner's mobile device. This allows the alarm system to provide comprehensive monitoring and notification capabilities while the mobile device handles the energy-intensive functions of continuous communication and alert delivery, thereby reducing the energy burden on the vehicle's alarm system battery.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A vehicle security alarm assembly includes a plurality of window sensors coupled to windows of a vehicle and plurality of handle sensors coupled to door handles of the vehicle. A motion sensing array is coupled to the vehicle to detect motion proximate the vehicle. Each of the window sensors, the handle sensors and the motion sensing array is in communication with the alarm system of the vehicle to selectively trigger the alarm system. A surveillance unit is mounted to a rear view mirror of the vehicle thereby facilitating the surveillance unit to surveil a back seat of the vehicle. A personal electronic device is included that is in communication with the alarm system for alerting an owner of the vehicle when the alarm system is triggered.
