Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice recognition systems in smart homes face issues such as voice data loss, decreased performance, and security concerns due to centralized hub devices, leading to network congestion and bottlenecks, as they rely on pre-defined hubs for processing user voice commands.
Innovation Solution
An electronic device capable of dynamically selecting a hub device based on user location, using a microphone, communication interface, and processor to determine user presence, identify nearby devices, and perform voice recognition by gathering voice data from multiple devices, thereby distributing the processing load and improving security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voice data is transmitted to a pre-defined hub device for processing, then centralized control is achieved, but network congestion and bottlenecks occur
Solution Approach 1:
The patent segments the centralized hub device into multiple distributed electronic devices, each capable of independent voice recognition. Instead of all devices relying on a single hub, each device can process voice data locally or relay to other devices, dividing the processing load and eliminating network bottlenecks while maintaining recognition accuracy.
Solution Approach 2:
The patent introduces a new dimension of device selection by adding location-based criteria to the voice recognition process. Devices determine user presence around them and select the nearest device for processing, adding spatial awareness to the system architecture. This dimensional change allows distributed processing without sacrificing centralized coordination benefits.
2Device complexity
If a pre-defined hub device processes all voice data, then system control is simplified, but security risks increase due to data concentration
Solution Approach 1:
The patent segments the centralized data processing function across multiple electronic devices. Each device can independently process voice data locally or relay to other devices in the network, preventing data concentration in a single hub. This segmentation maintains security by distributing sensitive information while preserving system control through coordinated device selection based on user proximity.
3Area of stationary object
If voice data is received from a distance by a hub device, then coverage area is expanded, but voice recognition accuracy decreases due to static noise
Solution Approach 1:
The patent implements dynamic device selection where the system adapts to real-time user location. Instead of a fixed hub processing all requests, the system dynamically identifies which device is closest to the user and routes voice data to that device. This dynamic approach ensures high recognition accuracy by selecting the nearest device while maintaining wide coverage through the network of available devices.
Solution Approach 2:
The patent applies local quality by having each electronic device optimize for its immediate vicinity rather than requiring distant hub processing. Each device is equipped to handle voice recognition for users in its local area, providing high-quality recognition for nearby users while the network collectively covers larger areas through multiple local processing points.
