Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fixed bit rate encoding is used for tactile signals in wireless communication, then communication bandwidth is limited and packet loss occurs, but transmission efficiency cannot be improved to accommodate additional information
Solution Approach 1:
The patent applies dynamics by making the bit rate allocation dynamic rather than fixed. The tactile signal encoding bit rate is adjusted based on the presence and requirements of additional information. When additional information is present, the tactile signal bit rate is reduced to accommodate it; when absent, the full bit rate is allocated to the tactile signal. This dynamic adjustment resolves the contradiction by enabling efficient bandwidth utilization without causing packet loss.
Solution Approach 2:
The patent changes the parameter of bit rate allocation from a fixed value to a variable parameter. The encoding system monitors the communication conditions and signal requirements, then adjusts the tactile signal's bit rate parameter accordingly. This allows the system to optimize communication efficiency by allocating more bits to additional information when needed while maintaining tactile signal quality within available bandwidth, thereby preventing packet loss.
2Adaptability or versatility
If additional information is transmitted along with tactile signals, then communication bandwidth requirements increase, but fixed frame size limits the ability to accommodate variable data amounts
Solution Approach 1:
The patent applies segmentation by dividing the fixed frame into variable-length segments allocated to different signal types. The frame structure is segmented such that the tactile signal occupies a dynamic portion while additional information occupies the remaining portion. This segmentation allows the system to flexibly accommodate variable data amounts for different signal types within the fixed frame structure, achieving adaptability without requiring a completely new encoding system.
Solution Approach 2:
The patent introduces dynamic bit rate allocation within the fixed frame structure. The encoding system dynamically determines the bit rate for the tactile signal based on the amount of additional information present. This dynamic parameter adjustment enables the system to adapt to varying information requirements while maintaining the fixed frame size constraint, thereby achieving versatility without significantly increasing encoding system complexity.
3Reliability
If tactile signal transmission uses full bandwidth, then signal quality is maintained, but no room exists for inserting additional information without degrading signal quality
Solution Approach 1:
The patent changes the bit rate parameter of the tactile signal dynamically based on the presence of additional information. When additional information is transmitted, the tactile signal's bit rate is reduced to allocate bandwidth to the additional information. When additional information is absent, the tactile signal uses the full available bit rate. This parameter adjustment maintains signal quality within the available bandwidth while enabling additional information capacity, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The patent applies dynamics by making the tactile signal's encoding parameters adaptive rather than static. The system continuously monitors the communication conditions and adjusts the tactile signal's bit rate parameter in real-time. This dynamic adjustment ensures that signal quality is maintained at the highest possible level given the current bandwidth availability, while simultaneously enabling the system to accommodate additional information when bandwidth permits, thus achieving both reliability and versatility.

AI summary
As a bit stream generation method for generating a bit stream of transmission data in which a plurality of signals including at least a tactile signal is multiplexed, a signal transmission unrequired section of the tactile signal is determined and, in a case where the signal transmission unrequired section exists, the bit stream in which additional information other than the tactile signal is inserted into the signal transmission unrequired section is generated.
