Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wireline connection is used between the local alarm panel and central station, then reliable alarm reporting is achieved, but the connection can be disabled by a burglar

Engineering Contradiction:

Improvealarm reporting reliabilityVSAvoidvulnerability to wireline disruption

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a cellular transceiver as an intermediary communication device that enables wireless alarm reporting. The transceiver receives alarm signals from the local panel and transmits them to the central station via cellular networks, eliminating the need for physical wireline connections and thus removing the vulnerability to wireline disruption while maintaining reliable alarm reporting

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical wireline connection system with an electromagnetic wireless cellular communication system. This substitution eliminates the physical infrastructure that can be cut or disabled, using instead radio frequency transmission through cellular networks to achieve reliable alarm reporting without vulnerability to wireline disruption

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If a cellular transceiver is used for alarm reporting, then wireline vulnerability is eliminated, but status information reporting is limited

Engineering Contradiction:

Improvewireline disruption vulnerabilityVSAvoidstatus information reporting capability

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The patent enhances the cellular transceiver to perform multiple functions: it not only reports alarm events but also provides comprehensive status information about the security system. The transceiver is configured to transmit various status parameters including arming/disarming states, sensor conditions, and system events, making it a universal communication device that eliminates wireline vulnerability while fully restoring status information reporting capability

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements dynamic communication where the transceiver adaptively reports different types of information based on system state. The system can transition between reporting only alarm events and reporting comprehensive status information, allowing flexible information transmission that maintains cellular advantages while overcoming reporting limitations through dynamic message content adjustment

Inventive Principle:

Principle #15Dynamics

3Speed

If frequent polling is used to obtain status information, then real-time monitoring is achieved, but FCC regulations may be violated

Engineering Contradiction:

Improvestatus information update speedVSAvoidFCC regulatory compliance

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent changes the timing parameters of polling operations to comply with FCC regulations. The system implements randomized polling intervals and respects minimum interval requirements, dynamically adjusting polling frequency based on regulatory constraints while still providing timely status information updates through optimized communication protocols and event-triggered reporting mechanisms

Inventive Principle:

Principle #35Parameter changes

AI summary

A method and apparatus are provided for obtaining the status of a security system. The method includes the steps of providing a security system for a protected premises, coupling the security system to a central monitoring station through a short-range radio and a broadband connection that receives polling messages from the protected premises where the broadband connection forwards the polling message to the central station, the central station receiving a status request from an authorized user of the protected premises, in response to the polling message, the central station transmitting the status request to the security system through the broadband connection and short range radio system and the security system transmitting a status report through the short range radio and the broadband connection to the central monitoring station in response to the request.
