Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple devices are connected through a single interface in mobile platforms, then device connectivity and data transmission efficiency are improved, but management complexity of connection information increases
Solution Approach 1:
The patent introduces a multi-link manager as an intermediary component that centrally manages connection information between multiple devices. This manager maintains a management table storing connection details and coordinates communication between devices, thereby simplifying the management complexity while enabling efficient multi-device connectivity through a single interface.
Solution Approach 2:
The device interface is designed with multi-functionality to handle multiple device connections through a single port. The interface can simultaneously manage different device types (host, embedded memory, external memory system) and perform multiple operations (data transmission, connection management, packet routing), reducing the need for separate interfaces while maintaining efficiency.
2Measurement precision
If connection information is maintained in a management table for multiple devices, then device management accuracy is improved, but information storage and processing overhead increases
Solution Approach 1:
The management table is segmented into specific fields (device ID field, connection status field) that organize connection information in a structured manner. This segmentation allows for efficient storage and retrieval of connection data, maintaining high management accuracy while minimizing storage overhead by only storing essential information in dedicated fields.
3Reliability
If packets with connection information are transmitted between all connected devices, then real-time connection management is improved, but communication overhead increases
Solution Approach 1:
The patent implements a feedback mechanism where devices transmit packets containing connection information (such as device ID packets) to the multi-link manager and other connected devices. This feedback loop enables real-time updates of connection status in the management table, ensuring reliable connection management while allowing devices to operate autonomously based on received information, thereby reducing unnecessary communication overhead.
