Smoke Detector Testing via Infrared Remote Activation

Solution Overview

Problem

Existing smoke detectors require manual activation for testing, which can be inconvenient and may not ensure proper functionality without actual smoke detection, especially in inaccessible locations like ceilings.

Innovation Solution

A detachable testing device with a rod and light detector that uses infrared light from a remote control to automatically activate the smoke detector's test button, allowing for remote verification of the device's operation and storing/test results, including a unique identifier.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual activation is used for testing smoke detectors, then the testing process is simple and direct, but it is inconvenient and inaccessible especially for ceiling-mounted detectors

Engineering Contradiction:

Improveconvenience of testingVSAvoidtesting mechanism complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the manual mechanical button-pressing action with an optical field (infrared light) to activate the test function. The remote control transmits infrared signals that trigger the smoke detector's test mode without requiring physical contact, thereby substituting a mechanical interaction with a non-contact optical field interaction.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a remote control device as an intermediary between the user and the smoke detector. This intermediary transmits commands via infrared light, allowing the user to activate testing functions without directly touching the smoke detector, thus solving the accessibility problem for ceiling-mounted units.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If a detachable testing device with light detector is used, then remote testing is enabled, but the device complexity increases

Engineering Contradiction:

Improveremote testing capabilityVSAvoidtesting device structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent makes the smoke detector compatible with both manual button pressing and remote infrared activation, allowing it to serve multiple testing modes. The detector's circuitry is designed to recognize both direct button presses and infrared signals, providing universal testing capability without requiring separate dedicated systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a remote control device as an intermediary between the user and the smoke detector. This intermediary transmits commands via infrared light, allowing the user to activate testing functions without directly touching the smoke detector, thus solving the accessibility problem for ceiling-mounted units.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Extent of automation

If automated light-triggered testing is implemented, then manual intervention is reduced, but the system requires additional components like light detectors and remote controls

Engineering Contradiction:

Improveautomatic test activationVSAvoidsystem components

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The patent replaces the manual mechanical button-pressing action with an optical field (infrared light) to activate the test function. The remote control transmits infrared signals that trigger the smoke detector's test mode without requiring physical contact, thereby substituting a mechanical interaction with a non-contact optical field interaction.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The smoke detector is designed to automatically initiate its test sequence when it detects the specific infrared signal from the remote control. The system self-activates the testing function upon receiving the optical trigger, eliminating the need for manual button pressing and providing automated testing capability.

Inventive Principle:

Principle #25Self-service

AI summary

A testing device is provided that may be attachable and detachable from a smoke detector. The testing device may have a rod that pushes a testing button on the smoke detector. The testing device may have a light detector which will actuate the rod to push the testing button if the light from an appropriate remote control or other light source is directed onto it, in order to verify that the smoke detector is operating properly without manually pushing the testing button. The testing device may store a unique identifier (ID) and generate and transmit data pertaining to results of the testing of the smoke detector.
