Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple sensor data are processed through conventional memory access methods, then data processing capability is improved, but memory bandwidth and power consumption increase
Solution Approach 1:
The system segments the data processing function into multiple preprocessors (first preprocessor, second preprocessor, etc.), each handling specific sensor data independently. This segmentation enables parallel processing of multiple sensor inputs without requiring centralized memory access, thereby improving processing capability while reducing memory bandwidth consumption and power usage.
Solution Approach 2:
The patent introduces a switching circuit as an intermediary component that routes sensor data directly between preprocessors and the data processing device, bypassing memory for active data. This intermediary mechanism eliminates unnecessary memory access operations, reducing both memory bandwidth consumption and power consumption while maintaining high processing capability.
2Productivity
If multiple sensor data are processed through conventional memory access methods, then data processing capability is improved, but memory bandwidth increases
Solution Approach 1:
By dividing the processing system into multiple specialized preprocessors that handle different sensor data streams independently, the system eliminates the need for repeated memory access operations. Each preprocessor maintains local processing capability, segmenting the data flow to reduce overall memory bandwidth requirements while preserving high processing capability.
Solution Approach 2:
The switching circuit serves as an intermediary that establishes direct data pathways between sensors and preprocessors, bypassing memory for active data transmission. This intermediary structure reduces memory bandwidth consumption by eliminating unnecessary read/write operations while maintaining high data processing throughput.
3Productivity
If sensor data are corrected and processed with multiple preprocessors, then processing efficiency is improved, but device complexity increases
Solution Approach 1:
The system divides processing functions into multiple specialized preprocessors, each optimized for specific correction tasks (e.g., lens shading correction, bad pixel correction). This functional segmentation improves processing efficiency by enabling parallel specialized operations while managing complexity through modular, standardized preprocessor units with consistent interfaces.
Solution Approach 2:
The patent implements universal preprocessor modules that can handle multiple types of sensor data and correction functions. Each preprocessor is designed with multi-functional capability to process different sensor inputs (image sensors, depth sensors, etc.) through standardized correction algorithms, improving processing efficiency while controlling complexity through reusability.
4Use of energy by moving object
If on-the-fly processing is performed without memory access, then power consumption is reduced, but processing flexibility decreases
Solution Approach 1:
The system implements dynamic routing through a switching circuit that can adaptively direct sensor data to appropriate preprocessors based on real-time processing needs. This dynamic configuration enables on-the-fly processing without memory access while maintaining processing flexibility, as the switching circuit can reconfigure data pathways dynamically to accommodate different processing scenarios and sensor combinations.
