Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a wireless charging module is designed with a metallic enclosure, then structural strength and shielding are improved, but inductive power transfer efficiency deteriorates due to metal interference
Solution Approach 1:
The wireless charging module is divided into separate functional regions: a metallic portion for structural support and shielding, and a non-metallic portion for inductive power transfer. This segmentation allows each material to perform its optimal function without interfering with the other.
Solution Approach 2:
Different portions of the module have different material properties tailored to their specific functions. The metallic portion provides structural strength and electromagnetic shielding where needed, while the non-metallic portion enables efficient inductive coupling in the region where power transfer occurs.
2Device complexity
If wireless power delivery systems use fixed power levels, then system complexity is reduced, but adaptability to different device power requirements deteriorates
Solution Approach 1:
The wireless charging module incorporates dynamic power adjustment capability through NFC communication between the charging module and the information handling system. The system can sense device requirements and adjust power delivery levels dynamically, transitioning from static to adaptive power management.
Solution Approach 2:
The system uses NFC communication to establish feedback loops between the wireless charging module and the target device. This allows the system to receive information about device power needs and adjust the power delivery accordingly, enabling adaptive power management.
