Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a fixed data transmission format is used, then data transmission compatibility is ensured, but power consumption increases due to transmission of unnecessary data
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed data transmission format to a dynamic variable-bit-length format. The data transmission unit is divided into multiple byte fields (first byte to sixth byte), where each byte can be dynamically adjusted based on the actual data content. This allows the transmission format to adapt to different data types and lengths, reducing unnecessary data transmission while maintaining compatibility through defined field structures.
Solution Approach 2:
The patent implements parameter changes by modifying the bit-length of data transmission units. Instead of transmitting fixed 6-byte packets, the system dynamically adjusts the number of bytes transmitted based on the actual data requirements. For example, when only key pressing data needs to be transmitted, only the necessary bytes are sent, reducing power consumption while maintaining data integrity and host compatibility.
2Duration of action of stationary object
If a fixed data transmission format is used, then system compatibility is maintained, but battery life decreases due to unnecessary data transmission
Solution Approach 1:
The patent applies the extraction principle by selectively transmitting only the necessary data fields based on the actual input data type. The data transmission unit is structured with multiple optional byte fields, and the system extracts and transmits only the required portions. For instance, when only displacement data needs transmission, the system omits unnecessary fields like wheel displacement bytes, reducing energy loss and extending battery life.
Solution Approach 2:
The patent implements partial action by transmitting a subset of the full data structure based on actual needs. Instead of always transmitting all six bytes, the system transmits only the necessary portion (1-6 bytes) depending on the data type. This partial transmission approach reduces energy consumption significantly while maintaining complete functionality, directly extending battery operation duration.
3Use of energy by moving object
If variable-bit-length data is transmitted, then power consumption is reduced, but data conversion complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the data transmission unit into distinct byte fields (first byte to sixth byte), where each field has a specific function. The first byte contains key pressing data, the second and third bytes contain displacement data, and subsequent bytes contain optional wheel displacement data. This segmented structure simplifies the conversion process by providing clear boundaries and defined roles for each data portion, reducing overall conversion complexity despite the variable length.
Solution Approach 2:
The patent implements universality by designing a multi-functional data transmission structure that can handle various data types within a unified framework. The same six-byte structure accommodates different data combinations (key pressing only, displacement only, wheel displacement, or combinations thereof). This universal structure reduces conversion complexity by providing a consistent template that adapts to different scenarios without requiring separate conversion logic for each data type.

AI summary
A dynamic data transmission format adjustment method is provided. Firstly, a peripheral device raw input data is acquired from a device main body of a wireless peripheral device. Then, the peripheral device raw input data is converted into a variable-bit-length peripheral device transmission data according to a dynamic data transmission format conversion rule. Then, a network transmission packet containing the variable-bit-length peripheral device transmission data is generated, and the network transmission packet is transmitted to a wireless receiver of the wireless peripheral device. Then, the variable-bit-length peripheral device transmission data in the network transmission packet is converted and restored into a fixed-bit-length peripheral device transmission data according to the dynamic data transmission format conversion rule. Then, the fixed-bit-length peripheral device transmission data is transmitted from the wireless receiver to a computer host.
