Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for alarm indicating output devices are inflexible and unable to accommodate a variable plurality of devices, failing to meet current and future needs for different types and combinations of output devices in regional monitoring systems.
Innovation Solution
A multiple output device elongated mounting plate with electrical connectors and mechanical attachment features that can support various types of alarm indicating devices, including audible, visual, and audio/visual units, allowing for flexible installation and future upgrades by being longer than standard electrical boxes and using friction or snap fits for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard electrical box mounting system is used, then the installation is simple and meets current needs, but it cannot accommodate a variable plurality of output devices or future upgrades
Solution Approach 1:
The mounting system is divided into a modular plate structure with multiple independent mounting positions, each capable of supporting different output devices. The plate is segmented into distinct mounting locations that can be independently configured, allowing flexibility in accommodating varying numbers and types of devices without requiring a complete system redesign.
Solution Approach 2:
The mounting plate serves multiple functions: it provides structural support for various output devices, incorporates electrical connectors for power and signal distribution, includes attachment features for secure mounting, and offers a standardized interface that can accommodate different device types. This multi-functional design eliminates the need for separate mounting solutions for each device type.
2Adaptability or versatility
If the mounting plate is made longer to support more devices, then the versatility increases, but the compatibility with standard electrical boxes may be reduced
Solution Approach 1:
The mounting plate utilizes the vertical dimension and depth space within the electrical box rather than only horizontal expansion. By designing the plate to extend into the available depth and vertical clearance, the system can accommodate multiple devices in a compact arrangement that fits within standard electrical box dimensions while still providing support for a variable plurality of output devices.
3Reliability
If mechanical attachment features are added for secure device mounting, then the reliability of device attachment improves, but the ease of installation and device replacement decreases
Solution Approach 1:
The mechanical attachment features incorporate removable and reconfigurable elements that transition between a secure locked state during operation and an easily released state during installation or maintenance. The attachment mechanism allows for quick release and reconfiguration without requiring complex tools or procedures, balancing reliability during normal operation with ease of installation and replacement.
