Solution Overview

Problem

The frequent replacement of smoke alarm devices in buildings leads to significant labor and financial burdens due to the need for frequent drilling and potential damage to ceilings, with existing solutions failing to efficiently manage the process and prevent unauthorized removal.

Innovation Solution

A versatile adapter for smoke alarm devices that couples with different bases, featuring a safety element to prevent unauthorized removal and allowing for quick installation without drilling, using a combination of rings, grooves, catches, and a securing mechanism that can only be released with a special tool, and an underside designed for adhesive or screw attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If smoke detectors are permanently attached to the ceiling using screws or adhesive, then unauthorized removal is prevented, but replacement requires damaging the ceiling and involves significant labor

Engineering Contradiction:
Improveprevention of unauthorized removalVSAvoidreplacement rate per day
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system is divided into three separable components: the ceiling base (permanently mounted), the adapter (reusable intermediary), and the smoke detector body (replaceable). This segmentation allows the base to remain fixed while the detector and adapter can be easily swapped without damaging the ceiling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adapter serves as an intermediary component between the ceiling base and the smoke detector body. It features a locking mechanism that secures the detector while allowing authorized removal with a special tool, thus preventing unauthorized removal without requiring permanent attachment to the ceiling.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If bases from different manufacturers are used, then compatibility with various smoke detector types is achieved, but each base requires different drill holes and mounting methods

Engineering Contradiction:
Improvecompatibility with different smoke detector basesVSAvoidnumber of different mounting configurations
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adapter is designed with universal compatibility features including multiple ring sizes, grooves, and catching elements that can accommodate various base types from different manufacturers. A single adapter design can interface with multiple base configurations, eliminating the need for manufacturer-specific mounting solutions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If smoke detectors are replaced frequently according to maintenance intervals, then safety reliability is maintained, but labor costs and ceiling damage accumulate

Engineering Contradiction:
Improvesafety detection reliabilityVSAvoidtime for replacement per device
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The adapter is pre-installed on the ceiling base before the smoke detector is mounted. This preliminary action ensures that when replacement is needed, only the detector body and adapter need to be swapped as a unit, without requiring removal of the base or additional drilling, thus significantly reducing replacement time.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If a locking mechanism is added to prevent unauthorized removal, then security is improved, but installation complexity and time increase

Engineering Contradiction:
Improveprotection against unauthorized removalVSAvoidinstallation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking mechanism is designed as a disposable or limited-life component integrated into the adapter. After a certain period or number of uses, the entire adapter (including the locking mechanism) is replaced along with the smoke detector, eliminating the need for complex maintenance of the locking mechanism itself while providing adequate security during the detector's service life.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

The invention relates to an adapter for smoke detectors, comprising a top and a bottom surface, for use with smoke detector bases mounted on ceilings or walls. The top surface of the adapter is coupled to the base of a smoke detector during use. According to the invention, the top surface of the adapter is provided with rings, grooves, notches, and/or recesses designed to allow coupling with at least two different bases of different smoke detectors. This reduces the time required to replace a smoke detector when simultaneously changing the system. Safety features ensure compliance with usage requirements.
