Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building automation systems require pre-encoded video files with control information and specific device programs, limiting flexibility in controlling devices, as only predetermined programs can be started with these files.
Innovation Solution
A method and control device that analyze any media file to extract relevant control information, using algorithms like speech and image recognition, allowing flexible control of devices integrated into the system without pre-encoded data, enabling users to control devices directly from media files like videos or recipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video files are pre-encoded with control information and devices contain preset programs, then device control can be achieved, but system flexibility is limited and only predetermined programs can be started
Solution Approach 1:
The system performs self-service by automatically analyzing media files to extract control information without requiring manual pre-encoding or user configuration. The analysis unit autonomously processes media files, identifies control-relevant information, and generates control commands, eliminating the need for predetermined programs and pre-encoded video files.
Solution Approach 2:
The patent replaces the mechanical system of pre-encoded control data and preset programs with an intelligent analysis system. Instead of relying on predefined control information embedded in media files, the system uses analysis units with algorithms to automatically extract control information from any media file, substituting rigid pre-programming with flexible automated content analysis.
2Ease of operation
If manual data entry is required in the building automation system, then control precision can be maintained, but user convenience deteriorates
Solution Approach 1:
The system implements feedback mechanisms where the analysis unit continuously monitors media file content and adjusts its analysis based on extracted information quality. The control device receives feedback from devices about their status and automatically adjusts control commands, creating a closed-loop system that maintains accuracy while automating the process.
Solution Approach 2:
The analysis unit serves as an intermediary between media files and the building automation system. It automatically extracts control information from diverse media formats and translates it into system-compatible commands, eliminating the need for manual data entry while maintaining information accuracy through automated parsing and validation algorithms.
3Speed
If analysis of media files is performed in real-time, then responsiveness is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary analysis by pre-processing media files to identify control-relevant segments before executing full analysis. The analysis unit scans media files for control information markers and prepares extraction routines in advance, enabling faster real-time processing when actual control actions are required.
Solution Approach 2:
The analysis system dynamically adjusts its processing intensity based on real-time requirements. When control actions are needed, the system intensifies analysis to extract information quickly. Between control events, it reduces processing load by monitoring only for new control-relevant content, optimizing the balance between responsiveness and resource consumption.
