Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional manufacturing systems face inefficiencies and downtime due to unpredictable component failures and quality variations, leading to increased energy consumption, unscheduled maintenance, and product defects, as they rely on trial-and-error methods rather than predictive analytics.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional trial-and-error methods are used for manufacturing monitoring, then system complexity is low, but productivity is reduced due to unscheduled downtime and defects
Solution Approach 1:
The patent segments the manufacturing system into multiple monitoring zones with sensors placed at different locations, each monitoring specific parameters. This allows targeted monitoring of critical components without requiring system-wide complexity, improving productivity by focusing resources on high-risk areas.
Solution Approach 2:
The system performs preliminary analysis by continuously collecting and analyzing sensor data to predict potential failures before they occur. This enables proactive maintenance scheduling, preventing unscheduled downtime and maintaining high productivity without requiring complex intervention systems.
2Reliability
If continuous monitoring of all components is implemented, then reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements differentiated monitoring strategies where critical components receive continuous monitoring while non-critical components are monitored periodically or only when anomalies are detected. This selective approach maintains equipment reliability for essential components while reducing overall energy consumption of the monitoring system.
Solution Approach 2:
The system applies partial monitoring by focusing computational resources and sensor activation only on components showing signs of potential failure or during critical manufacturing phases. This reduces energy consumption while maintaining reliability by intensifying monitoring only when necessary.
3Measurement precision
If detailed component-level data collection is performed, then measurement precision is improved, but data processing load increases
Solution Approach 1:
The patent extracts only the most relevant features and parameters from raw sensor data using signal processing and filtering techniques. By extracting critical information such as vibration frequencies, temperature trends, and power consumption patterns, the system achieves high measurement precision while reducing the volume of data requiring processing, thereby lowering processor power consumption.
Solution Approach 2:
The system performs preliminary data processing and filtering at the edge devices before transmitting data to central processors. This preliminary aggregation and filtering of raw sensor data reduces the computational load on main processors while maintaining measurement precision by preserving critical signal characteristics.
4Loss of time
If predictive maintenance is implemented using machine learning, then loss of time is reduced, but device complexity increases
Solution Approach 1:
The patent introduces machine learning models as intermediary components that automatically analyze sensor data and predict failures. These models act as mediators between raw data and maintenance decisions, reducing downtime by providing automated predictions while managing complexity through modular model deployment and interpretation tools.
Solution Approach 2:
The predictive maintenance system enables self-service by automatically monitoring equipment conditions and generating maintenance alerts without requiring constant human intervention. The machine learning models autonomously identify patterns and predict failures, reducing downtime while managing complexity through automated decision-support rather than full automation.
