Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shared memory is used for communication between CPUs in different devices, then data can be transmitted between processors, but the signal transmission speed becomes slow when one CPU is using the shared memory
Solution Approach 1:
The patent divides the communication path into two segments: a first internal communication path within the first device and a second internal communication path within the second device. This segmentation allows the control signal to bypass the shared memory and external device interfaces, enabling rapid transmission through dedicated internal paths while maintaining data transmission capability between different devices.
Solution Approach 2:
The patent introduces a storage medium as an intermediary component that is accessible by both the first and second processors through their respective internal communication paths. This intermediary storage medium enables direct data exchange between processors without requiring shared memory, thus achieving fast signal transmission while preserving inter-device communication reliability.
2Adaptability or versatility
If signals are transmitted via multiple devices and shared memory, then communication between external devices and control target devices is enabled, but the transmission time increases
Solution Approach 1:
The patent establishes preliminary communication paths (first and second internal communication paths) between the first processor and storage medium, and between the storage medium and second processor. These pre-configured paths enable immediate signal transmission without requiring signal routing through multiple external devices, thus reducing transmission time while maintaining versatile communication capability.
Solution Approach 2:
The patent creates a new dimensional communication path by introducing an internal communication pathway that bypasses the traditional external device interface route. This dimensional change in signal transmission architecture allows simultaneous access to multiple devices through the storage medium without sequential delays, reducing time loss while preserving adaptability.

AI summary
A signal processing system includes: a first device to receive a control signal from an external device; a second device connected to the first device and to control a control target device; and a first storage medium connected to the first and second devices. The first device includes a first processor to output the control signal to the second device and a second storage medium connected to the first processor via a first internal communication path. The second device includes a second processor to control the control target device based on the control signal and a third storage medium connected to the second processor via a second internal communication path. The first storage medium is connected to the first and second internal communication pathes. The first storage medium stores the control signal input via the first internal communication path, and outputs the control signal via the second internal communication path.
