Innovation Solution
A data transmission device equipped with a TypeC interface, a wireless module, and a microprocessor that receives media data in DP protocol format, transforms it into MIPI or I2S format, compresses and encodes it into H.264/H.265 or AAC format, and transmits it wirelessly to a receiving device, enabling driver-free and efficient media sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional screen transmission devices are used, then screen mirroring can be achieved, but driver installation and complex setup are required
Solution Approach 1:
The patent uses Type-C interface as an intermediary that directly connects the terminal device to the data receiving device, eliminating the need for traditional wireless screen transmission devices that require driver installation. The Type-C interface handles both data transmission and protocol conversion, serving as a mediator that simplifies the connection process while maintaining compatibility between different devices.
Solution Approach 2:
The patent leverages the universal Type-C interface standard that is widely supported by modern devices, allowing the same interface to handle both power transmission and data transmission (including DP protocol). This multi-functionality eliminates the need for device-specific drivers and setup procedures, as Type-C is a standardized universal connection method.
2Reliability
If media data is transmitted using DP protocol through TypeC interface, then transmission quality is maintained, but data format compatibility with receiving devices is limited
Solution Approach 1:
The patent segments the data transmission process into distinct stages: the Type-C interface receives media data in DP protocol format, the first data transformation chip converts it to MIPI or I2S format, and the microprocessor further encodes it to H.264/H.265 or AAC format. This segmentation allows each component to handle specific format conversions, ensuring both high-quality transmission and broad compatibility with different receiving devices.
Solution Approach 2:
The patent changes the data format parameters through multiple transformation stages. The first data transformation chip changes the interface protocol parameter from DP to MIPI/I2S, and the microprocessor changes the encoding format parameter to H.264/H.265 or AAC. These parameter changes enable the system to maintain high transmission quality while adapting to various receiving device requirements.
3Adaptability or versatility
If data transformation and encoding are performed, then compatibility is improved, but processing time and complexity increase
Solution Approach 1:
The patent merges the data transformation and encoding functions into an integrated processing pipeline where the first data transformation chip and microprocessor work together as a unified system. This integration reduces the overall device complexity compared to having separate independent components, while still providing comprehensive format compatibility through the combined transformation and encoding capabilities.
