Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mechanical battery charging methods are used, then devices can be charged, but connectors experience wear and tear, and the system becomes complex and unreliable
Solution Approach 1:
The patent replaces mechanical connectors with wireless electromagnetic induction charging. The charging system uses a transmitter coil in the charging station and a receiver coil in the device, eliminating physical plug-and-socket connections. This substitution resolves the contradiction by removing mechanical wear while maintaining charging functionality, thereby improving reliability without adding complexity.
2Productivity
If multiple wireless chargers are deployed, then charging availability increases, but coordination and authentication become complex
Solution Approach 1:
The patent implements feedback mechanisms where wireless chargers broadcast their status (available, occupied, charging rate) and devices query or receive this information to make intelligent decisions. The system uses handshaking protocols and authentication exchanges between chargers and devices, allowing multiple chargers to operate independently while maintaining system-wide coordination. This feedback loop enables high productivity through multiple chargers without proportionally increasing coordination complexity.
Solution Approach 2:
Each wireless charger operates autonomously, independently managing its own charging sessions, authentication, and status broadcasting. Devices similarly self-select chargers based on broadcast information without requiring centralized control. This self-service approach allows multiple chargers to scale the system's productivity while keeping individual charger complexity low.
3Loss of time
If wireless charging is implemented, then down-time is reduced and deployment efficiency increases, but authentication and coordination protocols are required
Solution Approach 1:
The patent performs authentication and coordination actions before the actual charging begins. Devices and chargers exchange authentication credentials, verify compatibility, and establish charging parameters in advance through handshaking protocols. This preliminary action ensures that when charging starts, it can proceed immediately without interruptions, thus reducing down-time while containing protocol complexity to the pre-charging phase.
