Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single central computing device is configured to handle all computing tasks, then system control is simplified, but computational delays occur due to excessive computing load
Solution Approach 1:
The patent divides the centralized computing system into multiple distributed processing devices, each handling specific computing tasks independently. This segmentation reduces the computational load on any single device, eliminating bottlenecks and improving overall processing efficiency while maintaining coordinated system control through defined communication protocols.
Solution Approach 2:
The system transitions from a single-dimensional centralized control architecture to a multi-dimensional distributed architecture. Multiple processing devices operate in parallel across different spatial and functional dimensions, enabling simultaneous processing of multiple tasks and improving computational throughput without increasing control complexity.
2Productivity
If multiple processing devices are used to distribute computing tasks, then computational efficiency improves, but system complexity increases
Solution Approach 1:
Each processing device in the distributed system is designed with multi-functional capabilities, able to perform various computing tasks and communicate with different components. This universality reduces the need for specialized hardware for each function, simplifying the overall system architecture while maintaining high computational efficiency through parallel processing.
Solution Approach 2:
The system implements feedback mechanisms where processing devices continuously exchange status information and coordinate their operations. This feedback loop enables automatic load balancing, error handling, and synchronization, reducing the complexity of managing multiple devices by allowing them to self-regulate and adapt to changing conditions.
3Stability of the object's composition
If computing tasks are concentrated in one device, then data consistency is easier to maintain, but real-time processing capability deteriorates
Solution Approach 1:
The distributed processing devices establish predefined communication protocols and data synchronization mechanisms in advance. This preliminary setup ensures that data consistency is maintained automatically across devices through pre-coordinated actions, enabling real-time processing without the need for complex runtime consistency checks that would slow down operations.
