Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration is used for wireless device connections in meeting settings, then connection reliability can be ensured, but operation complexity and time consumption increase significantly
Solution Approach 1:
The system performs preliminary actions by pre-associating device information with location information before the meeting occurs. Reading devices at various locations continuously read and transmit device information (such as projector details) to the server, which stores this correspondence data. When a meeting is scheduled, the server already has the necessary connection information ready, eliminating the need for manual configuration during the meeting setup.
Solution Approach 2:
The system enables self-service by allowing the information terminal to automatically establish wireless connections based on location data. The terminal receives location information, queries the server for associated device information, and automatically configures and establishes connections without user intervention. This automated process resolves the contradiction by making the system serve itself rather than requiring manual operation.
2Extent of automation
If device information is manually input and configured, then connection accuracy can be maintained, but operation complexity increases
Solution Approach 1:
The system replaces manual mechanical configuration operations with automated electronic processes. Instead of manually inputting device information and configuring connections, the system uses reading devices to automatically capture device information, transmits it to the server, and enables automated connection establishment. This substitution of manual mechanical operations with electronic automation increases the extent of automation while managing system complexity through standardized protocols.
Solution Approach 2:
The server acts as an intermediary between reading devices and information terminals. It receives device information from reading devices, stores the correspondence between location and device data, and provides this information to information terminals. This intermediary role simplifies the overall system by centralizing data management and providing a standardized interface, thereby managing complexity while enabling automation.
3Speed
If wireless connection information is pre-distributed to all terminals, then connection speed improves, but information security and connection accuracy deteriorate
Solution Approach 1:
The system applies local quality by providing connection information specifically tailored to each location rather than distributing universal connection data to all terminals. Each information terminal receives device information corresponding to its current location through the server. This location-specific approach ensures that terminals receive accurate connection information for the correct device, maintaining connection accuracy while enabling fast connection establishment without broad pre-distribution.
Solution Approach 2:
The server performs preliminary actions by pre-storing the correspondence between location information and device information before connection is needed. When an information terminal needs to connect, it queries the server with its location data, and the server quickly retrieves and provides the corresponding device information. This preliminary preparation of data associations enables fast connection establishment while maintaining accuracy through precise location-based matching.
