Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single wireless adaptor is used to maintain connectivity, then device complexity is reduced, but connectivity reliability deteriorates when moving between access points
Solution Approach 1:
The system divides the wireless connectivity function into multiple independent adaptors (first wireless adaptor, second wireless adaptor, third wireless adaptor), each capable of independently scanning and connecting to access points. This segmentation allows the system to maintain connectivity through multiple simultaneous connections, improving reliability without requiring a single complex adaptor.
Solution Approach 2:
The system performs preliminary scanning and evaluation of available access points using multiple adaptors before switching connections. The mobile controller continuously scans for access points, evaluates signal strength and connectivity metrics, and prepares alternative connections in advance, ensuring seamless transitions and maintaining reliability.
2Reliability
If wireless adaptors scan frequently for available access points, then connectivity reliability improves, but use of energy increases
Solution Approach 1:
The system implements periodic scanning cycles where wireless adaptors scan for access points at predetermined intervals rather than continuously. The mobile controller cycles between scanning for available access points and maintaining current connections, with the ability to adjust scan frequency based on movement detection and connectivity stability, thereby reducing energy consumption while maintaining reliability.
Solution Approach 2:
The scanning frequency and intensity are dynamically adjusted based on system conditions. When the mobile device is detected to be moving or when signal strength deteriorates, scanning frequency increases. When connectivity is stable, scanning frequency decreases, optimizing the balance between reliability and energy consumption.
3Reliability
If multiple wireless adaptors operate independently to scan and connect, then connectivity reliability improves, but device complexity increases
Solution Approach 1:
The mobile controller serves as an intermediary that manages multiple independent wireless adaptors. It coordinates scanning operations, evaluates connectivity metrics from each adaptor, and determines optimal connection switching. This centralized coordination simplifies the management of multiple adaptors, maintaining reliability while controlling complexity through a single decision-making component.
Solution Approach 2:
The system merges the control and decision-making functions into a single mobile controller that manages all wireless adaptors. While the adaptors operate independently for scanning and connection, their management is unified through the mobile controller, which combines their capabilities to achieve reliable connectivity without proportionally increasing overall system complexity.
4Ease of operation
If the system automatically switches between access points based on signal strength, then ease of operation improves, but loss of time occurs during connection transitions
Solution Approach 1:
The system performs preliminary evaluation of alternative access points while maintaining the current connection. Multiple adaptors simultaneously scan and assess available access points, so when a switch is needed, the transition can occur rapidly with minimal disruption. The mobile controller prepares alternative connections in advance, reducing the time lost during switching.
Solution Approach 2:
The system maintains continuous connectivity by ensuring that at least one wireless adaptor remains connected to an access point during transitions. While one adaptor switches to a new access point, another adaptor maintains the existing connection, providing seamless service continuity and minimizing operational disruption and time loss.
