Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging channel is used, then charging convenience is improved, but energy transfer efficiency deteriorates
Solution Approach 1:
The patent implements dynamic switching between wireless and wired charging channels based on real-time detection of charging requirements and efficiency parameters. The control module automatically selects the optimal charging path, transitioning from static channel selection to dynamic adaptation, thereby resolving the contradiction between convenience and efficiency.
Solution Approach 2:
The patent employs feedback mechanisms where the control module continuously monitors charging status, efficiency parameters, and battery requirements. Based on this feedback, the system intelligently adjusts the charging channel selection and voltage/current parameters, enabling closed-loop control that optimizes both convenience and energy efficiency.
2Productivity
If charging voltage and current are not properly adjusted, then charging speed is improved, but device safety deteriorates
Solution Approach 1:
The patent dynamically adjusts charging voltage and current parameters based on battery state of charge, temperature, and charging stage. The control module modifies these parameters in real-time to optimize charging speed while preventing overheating and other safety issues, resolving the contradiction between speed and safety through parameter optimization.
Solution Approach 2:
The patent implements protective measures in advance by monitoring battery temperature and charging parameters before critical thresholds are reached. The system preemptively adjusts charging parameters or switches channels to prevent overheating and safety issues, rather than reacting after problems occur.
3Device complexity
If single charging channel is used, then device complexity is reduced, but charging adaptability deteriorates
Solution Approach 1:
The patent designs the charging device with multi-functional capability, supporting both wireless and wired charging channels through a unified control architecture. The control module can manage either or both channels, making the device adaptable to different charging scenarios while maintaining manageable complexity through shared control logic.
Solution Approach 2:
The patent separates the charging functionality into distinct modules (wireless charging module and wired charging module) that can be independently controlled by the control module. This segmentation allows flexible activation of only the needed channel, reducing effective complexity while maintaining adaptability.
