Innovation Solution
The development of adapters and cables that enable voltage conversion and compatibility checking through a logic circuit, allowing for the use of USB-C on one side and PoweredUSB on the other, with the ability to support higher voltages like 24V, and perform a handshake operation to ensure compatibility between terminal and peripheral devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If standard USB-C connection is used, then sleek industrial design is achieved, but voltage limitations prevent support for high-performance printers requiring higher voltage
Solution Approach 1:
The patent introduces an adapter as an intermediary device between the terminal device and peripheral device. The adapter includes a first end connecting to the terminal device, a second end connecting to the peripheral device, and a logic circuit that performs handshake operations to determine compatibility and enable voltage conversion, thereby resolving the voltage limitation of USB-C while maintaining sleek design
Solution Approach 2:
The patent changes the voltage parameter by using an adapter that can convert between different voltage standards. The logic circuit determines compatibility and enables the system to operate at higher voltages (such as 24V) when needed, while still using the USB-C connector for its aesthetic benefits
2Adaptability or versatility
If voltage conversion is implemented to support higher voltage requirements, then compatibility with high-performance printers is improved, but risk of incompatible power delivery increases
Solution Approach 1:
The patent performs a handshake operation in advance through the logic circuit to determine compatibility between the terminal device and peripheral device before enabling power delivery. This preliminary compatibility check ensures that voltage conversion is only activated when both devices support it, preventing incompatible power delivery
Solution Approach 2:
The logic circuit implements a feedback mechanism by performing handshake operations to continuously monitor and determine compatibility between devices. Based on the feedback from these operations, the system dynamically adjusts whether to enable voltage conversion and power delivery, ensuring safe operation
3Adaptability or versatility
If adapter with logic circuit is introduced, then voltage conversion and compatibility checking are enabled, but device complexity increases
Solution Approach 1:
The adapter is designed as a universal solution that can work with multiple USB standards and device types. The logic circuit performs multiple functions including handshake operations, compatibility determination, and voltage conversion control, allowing a single adapter design to support various USB standards without requiring multiple specialized adapters
