Measuring Device for Active and Standby Operating Hours
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for recording the operating hours of electrical devices are complex and often inaccurate, as they fail to distinguish between active and standby modes, leading to incorrect maintenance schedules and energy consumption tracking.
Innovation Solution
A measuring device with multiple counters to differentiate between active and standby modes by setting a defined power threshold, allowing for precise recording of active and standby times, and integrating the device within the electrical device to eliminate external cabling and provide accurate maintenance insights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single counter records total operating time including standby mode, then the device structure is simple, but the measurement precision of actual operating hours deteriorates
Solution Approach 1:
The patent divides the single counter into two separate counters: a first counter for recording active operating time and a second counter for recording standby time. This segmentation allows each counter to specialize in recording specific operational states, thereby improving measurement precision while maintaining reasonable structural complexity.
2Adaptability or versatility
If historical data is used to set power threshold, then the adaptability to device aging is improved, but the device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors power consumption and compares it against dynamically adjusted thresholds based on historical data. When the device's power consumption pattern changes due to aging, the system automatically adjusts the power threshold to maintain accurate differentiation between active and standby modes, ensuring long-term adaptability.
