Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile gardening, forestry, construction, or soil cultivation devices face challenges in efficiently determining and storing information about changes in their motor drive systems, particularly in resource-constrained environments, where limited resources necessitate resource-saving storage solutions.
Innovation Solution
A method involving repeated recording and comparison of motor drive system parameters over time, with storage only when significant changes are detected, utilizing a motor drive system with a detection device and evaluation unit to automatically determine and store information about changes, optimizing storage by minimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all recorded parameter values are stored continuously, then complete information is available, but resource consumption increases
Solution Approach 1:
The patent extracts only the essential information (changes in parameter values) from the continuous data stream, storing only when deviations occur rather than storing all recorded values. This selective extraction approach maintains information completeness for diagnostic purposes while significantly reducing storage resource consumption.
Solution Approach 2:
The system discards redundant information (unchanged parameter values) and recovers only the meaningful changes. By comparing current values with reference values and storing only deviations, the system eliminates waste of storage resources while preserving diagnostically relevant information.
2Measurement precision
If parameter recording frequency is increased, then detection precision improves, but resource consumption increases
Solution Approach 1:
The system uses feedback through comparison of recorded parameter values with reference values to determine when storage is necessary. This feedback mechanism allows the system to maintain high detection precision by continuously monitoring parameters while intelligently activating storage only when changes are detected, thus reducing overall resource consumption.
Solution Approach 2:
The system performs partial action by recording parameters continuously at high frequency for detection purposes, but applies excessive action (storage) only when necessary - i.e., when parameter changes are detected. This approach maintains measurement precision while avoiding the resource cost of continuously storing all high-frequency data.
3Loss of information
If storage operations are performed frequently, then information availability is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary action by establishing reference values before operation and continuously comparing current parameters against these references. This preliminary setup enables the system to determine storage necessity in advance, simplifying the decision-making process and reducing the complexity of storage management while ensuring information is available when changes occur.
Solution Approach 2:
The system serves itself by automatically comparing parameters, detecting changes, and triggering storage operations without external intervention. This self-service approach to change detection and storage management reduces the complexity of system control while maintaining information availability, as the system autonomously determines when storage is needed.
