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 due to signal drops when moving between access points
Solution Approach 1:
The wireless communication functionality is segmented into multiple independent adaptors (first wireless adaptor, second wireless adaptor) that can operate simultaneously. Each adaptor independently scans for and connects to access points, allowing the system to maintain connectivity through one adaptor while the other searches for alternatives, thereby improving connectivity reliability without requiring all adaptors to be part of a single complex integrated system.
Solution Approach 2:
Different adaptors are assigned different roles based on their operational state: one adaptor maintains the active connection while the other performs background scanning. This local differentiation of functionality allows each adaptor to optimize its specific task, with the maintaining adaptor focusing on connection stability and the scanning adaptor focusing on availability detection, thereby improving overall system reliability.
2Reliability
If background scanning is performed continuously to find alternative access points, then connectivity reliability is improved, but processing time and energy consumption increase
Solution Approach 1:
The system performs background scanning periodically rather than continuously - the second wireless adaptor scans at predetermined time intervals while the first adaptor maintains the active connection. This periodic scanning approach ensures that alternative access points are discovered and evaluated at regular intervals, improving connectivity reliability while minimizing the time and energy consumed compared to continuous scanning.
Solution Approach 2:
The background scanning operation continues uninterrupted during the maintenance of the active connection. The second wireless adaptor continuously scans for alternative access points without interrupting the first adaptor's connection maintenance, ensuring that connectivity options are always available while maintaining the current connection's stability.
3Reliability
If multiple wireless adaptors are used to scan and evaluate access points simultaneously, then connectivity robustness is improved, but device complexity increases
Solution Approach 1:
The system divides the wireless connectivity function into separate, independent adaptor units. Each adaptor has its own transmitter and receiver components, allowing them to operate in parallel without requiring a complex centralized control system. The controller simply coordinates between the adaptors, managing the segmentation of functionality to improve robustness while keeping individual component complexity low.
4Adaptability or versatility
If the system cycles between scanning and disconnecting connections at high frequency, then adaptability to changing signal conditions is improved, but stability of the connection deteriorates
Solution Approach 1:
The controller continuously monitors the signal strength and connection quality of both adaptors and uses this feedback to make informed decisions about which adaptor to switch to. The system compares the current connection's signal strength with available alternatives and only switches when the feedback indicates a significant improvement, thereby achieving adaptability to changing conditions while maintaining connection stability through deliberate, feedback-driven decisions.
