Solution Overview
Problem
Current microphone devices for security systems lack efficient audio analytics and power management within a single, compact housing, making them less effective in detecting specific sound events like gunshots or breaking glass, and often require complex installations.
Innovation Solution
A microphone device with a separate circuit board for audio analytics and another for power extraction, connected via Ethernet, allowing for centralized processing and power distribution within a single housing that can be easily mounted and integrated into security systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If audio analytics and power extraction are integrated into a single circuit board, then device complexity is reduced, but functional reliability and ease of repair deteriorate
Solution Approach 1:
The device is divided into separate circuit boards: a first circuit board for audio analytics functions and a second circuit board for power extraction functions. This segmentation allows each board to be independently designed, tested, and repaired, improving reliability while maintaining manageable device complexity through modular architecture.
2Volume of moving object
If multiple functional components are integrated into a single housing, then device compactness is improved, but ease of installation and maintenance deteriorates
Solution Approach 1:
The housing contains separately mounted circuit boards that can be independently accessed and replaced. The standardized housing design with designated mounting locations allows for easy installation while maintaining compact form factor, as components are organized in a modular manner within the single housing.
Solution Approach 2:
The single housing serves multiple functions: it protects the circuit boards, provides structural support, defines the acoustic environment for the microphone, and facilitates installation through standardized mounting interfaces. This multi-functionality achieves compactness without sacrificing ease of installation.
3Use of energy by moving object
If power extraction is performed separately from audio processing, then power management efficiency is improved, but device complexity increases
Solution Approach 1:
Power extraction is separated onto a dedicated second circuit board, improving power management efficiency through specialized circuitry. The complexity increase is mitigated by the modular design, where each board has a single focused function, making the overall system easier to understand and maintain despite having multiple components.
