Solution Overview

Problem

Existing alarm units face challenges with inconvenient and expensive hardwiring, limited battery life in self-contained systems, and time-consuming installation processes, particularly in existing structures and when multiple units need to be installed.

Innovation Solution

A mounting assembly and method for alarm units that includes a backplate with keys and a receptacle with triggers, allowing for fast installation and automatic activation, using a primary fastener with wedge-shaped ribs for secure wall attachment and a coupling receptacle that activates the alarm unit during installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If self-contained alarm units with internal power sources are used, then installation convenience is improved, but installation time increases due to requiring multiple screws and alignment

Engineering Contradiction:
Improveinstallation convenienceVSAvoidinstallation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The mounting system is divided into separate components: a backplate with keys that attaches to the wall, and a receptacle with triggers that attaches to the alarm unit. This segmentation allows the alarm unit to be mounted quickly by simply engaging the receptacle with the backplate, eliminating the need for multiple screws and complex alignment procedures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The keys and triggers act as intermediary elements between the backplate and receptacle. The keys on the backplate engage with the triggers on the receptacle, providing a simple mechanical interface that enables quick attachment without requiring precise alignment or multiple fastening operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If automatic activation is implemented, then user error is minimized, but device complexity increases due to additional triggers and electrical connections

Engineering Contradiction:
Improveactivation reliabilityVSAvoidmounting assembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting function and activation function are merged into a single operation. When the receptacle is attached to the backplate, the mechanical engagement of keys with triggers simultaneously completes both the mounting and activation processes, eliminating the need for separate activation steps.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system automatically activates the alarm unit through the mechanical engagement of the mounting components. The act of attaching the alarm unit itself triggers the activation process, as the keys physically actuate the triggers during the mounting operation, making the system self-activating without requiring separate user actions.

Inventive Principle:
Principle #25Self-service

AI summary

A mounting assembly and method for installing an alarm unit are provided. The mounting assembly includes a backplate having a front face and one or more keys extending from the front face, with the backplate being configured to be secured to a wall. The mounting assembly also includes a receptacle including one or more triggers electrically connected to a power source of the alarm unit, and defining one or more hanger recesses. The receptacle is configured to receive the one or more keys of the backplate in the one or more hanger recesses such that the one or more triggers are actuated by engagement with the one or more keys and relative movement between the backplate and the receptacle. The receptacle is physically secured to the backplate via engagement with the one or more keys.
