1Productivity

If a single microcontroller processes signals from multiple sensor devices, then the processing capability is sufficient, but the device complexity increases and operating speed decreases

Engineering Contradiction:

Improveoperating speedVSAvoiddevice complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the processing system into multiple independent arithmetic processing devices (first arithmetic processing device, second arithmetic processing device, etc.), each handling a portion of the sensor signal processing tasks. This segmentation allows parallel processing of sensor data, increasing overall operating speed while keeping each individual processing device relatively simple in configuration

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent combines multiple arithmetic processing devices to work together on processing signals from multiple sensor devices. By merging the processing capabilities of several devices and coordinating their operations through synchronization signals, the system achieves high-speed processing without requiring a single complex high-performance microcontroller

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If a high-performance microcontroller is used to process multiple sensor signals, then the processing capability is sufficient, but the configuration becomes complex

Engineering Contradiction:

Improveprocessing capabilityVSAvoidconfiguration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of using a single high-performance microcontroller with complex configuration, the patent segments the processing function across multiple simpler arithmetic processing devices. Each device has a relatively simple configuration but collectively they provide the necessary processing capability for multiple sensor devices

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each arithmetic processing device is designed with universal functionality to handle processing tasks for different sensor devices. This multi-functionality allows the system to process signals from multiple sensor types using standardized processing units, reducing overall configuration complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)
