Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate power and data connections are used for production accessories, then power delivery and data transfer can be achieved, but the number of connections increases and workflow efficiency decreases
Solution Approach 1:
The patent combines power delivery and data transfer functions into a single USB-C connection. The battery pack includes a USB-C port that simultaneously provides power output and enables data communication between connected devices, eliminating the need for separate power and data cables.
Solution Approach 2:
The USB-C port is designed to perform multiple functions: it can deliver power to external devices, enable bi-directional data transfer between devices, and support both power source and power sink operations. This multi-functional design reduces the number of required connections while maintaining full operational capability.
2Device complexity
If a single USB-C port is used for both power and data, then connection complexity is reduced, but the ability to provide simultaneous power to multiple devices and enable data transfer is limited
Solution Approach 1:
The battery pack includes multiple USB-C ports (at least two ports are described), allowing simultaneous power delivery to multiple devices. Each port can independently provide power and enable data transfer, with the ability to support multiple devices at once while maintaining bi-directional data communication capabilities.
Solution Approach 2:
The battery pack acts as an intermediary device that facilitates data transfer between connected devices. When two devices are connected to different USB-C ports on the battery pack, the battery pack's control circuit enables bi-directional data communication between them, allowing the battery pack to serve as a data bridge while also providing power to both devices.
3Power
If higher voltage power delivery is provided for cinema cameras, then power consumption requirements are met, but compatibility with lower voltage devices may be compromised
Solution Approach 1:
The USB-C ports are configured to dynamically negotiate and adjust voltage output based on the connected device's requirements. The battery pack can provide higher voltages for cinema cameras that require them, while automatically adjusting to lower voltages for devices with lower power requirements, ensuring broad compatibility across different device types.
Solution Approach 2:
The system changes electrical parameters (voltage and current) based on the connected device's needs. The USB-C implementation allows for variable power delivery, enabling the battery pack to output different voltage levels as required by different devices, from high voltage for cinema cameras to standard USB voltages for other devices.
