Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless communication components are included in the electronic device, then communication versatility is improved, but interference between components increases leading to reduced reliability
Solution Approach 1:
The patent introduces an intermediary system consisting of a detector and handover controller that mediates between multiple wireless communication components. The detector monitors interference levels between components, and the handover controller uses these measurements to determine optimal handover parameters, thereby resolving the contradiction by adding a coordinating layer that enables multiple components to operate together with reduced interference impact
Solution Approach 2:
The patent dynamically changes handover parameters based on measured interference conditions. By adjusting handover thresholds and timing parameters according to real-time interference measurements, the system adapts its operation to maintain reliability while supporting multiple wireless communication components
2Reliability
If handover control parameters are configured to mitigate interference, then reliability is improved, but handover decision complexity increases
Solution Approach 1:
The system implements self-service by automatically measuring interference between wireless components and autonomously determining handover parameters without requiring complex external configuration. The detector and controller work together to self-adjust handover settings based on real-time conditions, improving reliability while keeping the control mechanism relatively simple
Solution Approach 2:
The patent employs feedback mechanisms where the detector continuously monitors interference levels and feeds this information back to the handover controller. This closed-loop feedback system enables reliable handover decisions based on actual interference conditions without requiring complex predetermined parameter sets

AI summary
In some examples, to mitigate interference of wireless communications, an electronic device that includes a first type wireless component and a second type wireless component receives values of parameters relating to wireless communication using the first type wireless component. The electronic device determines, using a model of a relationship between the parameters relating to wireless communication using the first type wireless component and at least one handover parameter relating to wireless communication using the second type wireless component, a value of the at least one handover parameter based on the received values of the parameters relating to wireless communication using the first type wireless component. It is determined whether the electronic device should be handed over from a first access point to a second access point based on the determined value of the at least one handover parameter.
