Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial settings, owners or managers of electrical assets lack real-time data on usage frequency and maintenance needs, resorting to reactive maintenance and facing challenges in predicting equipment degradation, particularly in refrigeration compressors, leading to inefficiencies and failures.
Innovation Solution
A monitoring system that measures electrical characteristics like amperage, voltage, and power factor, using sensors and control systems to detect duty cycles, and generates alerts when thresholds are exceeded, enabling proactive maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manual tracking of equipment usage is implemented, then ownership awareness of asset utilization is improved, but labor time and operational complexity increase
Solution Approach 1:
The electrical asset monitoring system automatically collects and reports usage data without requiring manual intervention. Sensors embedded in or connected to electrical assets continuously monitor power consumption, operational status, and usage patterns, transmitting this information directly to the centralized platform, thereby eliminating the need for manual tracking while maintaining complete awareness of asset utilization
Solution Approach 2:
The patent replaces manual mechanical tracking methods with automated electronic sensing and communication systems. Electrical sensors, microcontrollers, and wireless communication modules substitute for human operators who would otherwise manually record usage data, transforming a labor-intensive process into an autonomous electronic monitoring system
2Reliability
If reactive maintenance is used, then immediate response to failures is achieved, but equipment degradation and downtime increase
Solution Approach 1:
The system performs preliminary maintenance actions by continuously monitoring electrical parameters such as current draw, power factor, and operational cycles to detect early signs of asset degradation. When anomalies are detected indicating potential failures, the system generates alerts that enable maintenance personnel to service equipment before actual failures occur, preventing downtime and extending asset life
Solution Approach 2:
The monitoring system establishes a continuous feedback loop where sensor data from electrical assets is constantly analyzed against baseline performance parameters. Deviations from normal operating patterns trigger automated alerts and notifications to maintenance teams, enabling timely intervention based on real-time condition monitoring rather than scheduled or reactive maintenance approaches
3Loss of information
If comprehensive monitoring of electrical assets is implemented, then asset utilization visibility is improved, but system complexity and cost increase
Solution Approach 1:
The system employs universal monitoring components that can interface with multiple types of electrical assets using standard communication protocols. The centralized platform processes data from various sensor types and asset categories through a unified architecture, reducing overall system complexity while maintaining comprehensive monitoring capabilities across diverse equipment
Solution Approach 2:
The patent introduces an intermediary centralized monitoring platform that acts as a mediator between distributed sensors on electrical assets and end-users. This intermediary layer aggregates, standardizes, and presents complex sensor data in simplified visual formats such as dashboards, charts, and alert notifications, thereby maintaining complete visibility while shielding users from underlying system complexity

AI summary
A monitoring system for electrical assets, for example industrial machines, includes monitoring devices measuring current and a controller arranged to communicate measured electrical characteristic values to a computer server which stores the values power values in a database record associated with each monitoring device. Each database record includes a time series of the electrical power values and irregular usage criteria indicative of an irregular usage of the asset to generate alerts as required. The server can also generate various reports including (i) graphically representing s the power values relative to active and idle thresholds to determine if the asset is active, idle or off; (ii) a heat map representing usage based on the power values; and (iii) a dashboard view showing the real time active or inactive status of each asset based on the power values.
