Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing approaches to monitoring industrial machines are inefficient due to the lack of optimal separation of signal processing functions for safety protection and operational management data, leading to increased complexity and cost, as well as potential interference between different data sets.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate signal processing hardware devices are provided for safety protection and management data, then independence and reliability of safety measurements are improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent segments signal processing into two hierarchical levels: Level 1 performs initial signal acquisition and waveform generation for all channels, while Level 2 performs measurement-specific processing. This segmentation allows safety and management data to share common hardware resources while maintaining independent processing paths, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The monitoring module is designed with universal signal processing capabilities that can serve multiple functions. The same hardware device processes both safety-critical measurements and management data by dynamically configuring signal processing parameters and data paths based on the measurement type, eliminating the need for separate dedicated hardware while maintaining reliability.
2Device complexity
If a single monitoring module processes both safety protection and management data, then device complexity is reduced, but interference between different data sets occurs and reliability of safety measurements deteriorates
Solution Approach 1:
The patent implements dynamic configuration capabilities within the single monitoring module. Signal processing parameters, data sampling rates, and processing algorithms can be dynamically adjusted based on whether safety or management measurements are being performed. This dynamic separation ensures that processing for one data type does not interfere with the other, maintaining reliability while using shared hardware.
3Adaptability or versatility
If management data users can freely configure and alter signal processing operations, then adaptability and ease of operation are improved, but safety protection measurements may be affected and reliability deteriorates
Solution Approach 1:
The patent applies different quality levels and configuration permissions to different data types. Management data processing allows flexible user configuration and adaptation, while safety measurement processing maintains fixed, validated parameters that cannot be altered. This local differentiation of configurability allows adaptability for management functions while preserving reliability for safety functions.
