Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automation systems require multiple sensors to detect various events, leading to increased complexity and cost, as they need to be installed and maintained across premises.
Innovation Solution
Implementing a single microphone sensor attached to a pipe that detects sounds and vibrations, generating audio signatures to recognize events and trigger automation tasks, reducing the need for multiple sensors by characterizing and logging sounds for automated responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensors are implemented to detect different types of events, then event detection capability is improved, but system complexity and cost increase
Solution Approach 1:
The patent applies universality by implementing a single microphone sensor that performs multiple detection functions. The microphone captures various sound types (knocking, breaking, glass breaking, vehicle arrival) and the system processes these sounds through audio signature generation and comparison to identify different event types, replacing the need for multiple specialized sensors with one multi-functional acoustic sensor
Solution Approach 2:
The patent merges multiple detection capabilities into a single integrated system. The microphone sensor, audio signature generation module, and event determination logic are combined into one system that simultaneously detects and distinguishes between multiple event types through acoustic analysis, consolidating what would traditionally require separate sensors for each event type
2Adaptability or versatility
If multiple sensors are implemented to detect different types of events, then event detection capability is improved, but implementation cost increases
Solution Approach 1:
The patent reduces implementation cost by deploying a single multi-functional microphone instead of multiple specialized sensors. The microphone serves as a universal acoustic detector for various event types, and the centralized audio processing system analyzes all sounds through a unified approach, significantly reducing hardware procurement and installation expenses
Solution Approach 2:
The patent uses audio signatures as informational copies of physical events. Instead of requiring physical sensors for each event type, the system creates acoustic fingerprint copies (audio signatures) that represent different events, allowing event identification through pattern matching rather than through multiple physical detection devices
3Reliability
If multiple sensors are implemented around the premises, then coverage of event detection is improved, but installation and maintenance complexity increases
Solution Approach 1:
The patent simplifies installation and maintenance by merging multiple sensor functions into a single microphone unit. Instead of installing and maintaining multiple sensors at different locations, the system uses one centralized acoustic sensor with sophisticated signal processing that can detect events throughout the premises, reducing both installation complexity and ongoing maintenance requirements
