Innovation Solution

A smoke detector system that uses a personal mobile computing device to establish a wireless communication channel with smoke detectors, allowing self-testing and data collection without direct internet connection, reducing energy consumption and enhancing security, while enabling centralized data storage and maintenance scheduling through a computer program product.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If smoke detectors are connected directly to the internet for self-testing and data transmission, then data management and monitoring are facilitated, but security risks increase and energy consumption increases

Engineering Contradiction:
Improvedata managementVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a mobile computing device as an intermediary between smoke detectors and the internet. The mobile device establishes a wireless communication channel with smoke detectors, collects self-test data locally, and then transmits data to a remote server via internet connection. This mediator approach allows smoke detectors to benefit from centralized data management without direct internet exposure, reducing security risks while maintaining operational ease.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If smoke detectors use high-energy wireless protocols for internet connectivity, then communication reliability is improved, but battery life is reduced

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidbattery life
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent implements periodic self-testing of smoke detectors rather than continuous monitoring. The mobile computing device triggers self-tests at scheduled intervals, and data transmission occurs periodically when the mobile device is in range. This periodic action reduces the energy consumption of wireless communication while maintaining sufficient monitoring reliability through regular checks.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The mobile computing device serves as an intermediary that buffers communication between smoke detectors and the remote server. The smoke detectors communicate with the mobile device using lower-energy protocols, while the mobile device handles higher-energy internet transmission independently. This separates the communication tasks, allowing smoke detectors to conserve battery life while maintaining reliable data collection.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If centralized data management is implemented through direct internet connection, then maintenance scheduling is improved, but device complexity increases

Engineering Contradiction:
Improvemaintenance schedulingVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The mobile computing device acts as an intermediary that simplifies the system architecture for smoke detectors. Instead of each detector needing direct internet connectivity and complex communication protocols, the mobile device handles all internet-related functions. The detectors only need simple wireless communication capabilities to interact with the mobile device, significantly reducing their complexity while still enabling centralized data management and maintenance scheduling.

Inventive Principle:
Principle #24Intermediary (Mediator)
