Engineering Contradiction Analysis
1Quantity of substance
If data compression is performed by the data processing component, then data storage capacity is improved, but processing burden and power consumption increase
Solution Approach 1:
The patent introduces an interface device as an intermediary component between the data processing component and the data store. This interface device includes dedicated compression circuitry that performs data compression independently, preventing the data processing component from being burdened with compression tasks. The interface device acts as a mediator that handles compression operations while the data processing component focuses on its primary data processing functions, thereby reducing overall system power consumption while maintaining effective data storage capacity.
2Quantity of substance
If data compression is performed by the data processing component, then data storage capacity is improved, but processing capability burden increases
Solution Approach 1:
The patent segments the data management system into distinct functional components: the data processing component for processing operations, and the interface device for compression and storage operations. By dividing the system architecture this way, the compression function is separated from the main data processing component, reducing its processing burden and complexity. The interface device's compression circuitry handles compression tasks independently, allowing the data processing component to maintain simpler, more focused functionality.
3Use of energy by moving object
If compression operations are performed autonomously by the interface device, then power efficiency is improved, but system control complexity increases
Solution Approach 1:
The interface device incorporates feedback mechanisms that monitor compression operations and system state, automatically adjusting compression parameters and notifying the data processing component when the data store is full or when intervention is needed. This feedback-based autonomous operation enables the interface device to manage compression efficiently without requiring constant microcontroller intervention, improving power efficiency while maintaining manageable system control through structured communication protocols.
