Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sensing function is introduced into the communication system, then sensing capability is improved, but signal scrambling reliability deteriorates because existing scrambling solutions only consider communication function
Solution Approach 1:
The patent applies multi-functionality by designing a scrambling sequence generation mechanism that simultaneously serves both communication and sensing functions. The apparatus generates scrambling sequences that can be used for signal scrambling in communication while also providing sensing capabilities through the same signal structure, eliminating the need for separate scrambling solutions for each function.
Solution Approach 2:
The patent changes the parameters of the scrambling sequence generation by introducing sensing-related information as input parameters. The scrambling sequence is generated based on both communication parameters and sensing parameters, allowing the system to adapt the scrambling behavior according to the specific sensing requirements while maintaining communication reliability.
2Measurement precision
If sensing-related information is used to generate scrambling sequence, then sensing performance is improved, but device complexity increases
Solution Approach 1:
The patent merges the sensing information processing with the existing scrambling sequence generation process. Instead of adding a separate sensing processing chain, the apparatus integrates sensing-related information into the scrambling sequence generator, combining both functions into a single processing block that reduces overall system complexity.
Solution Approach 2:
The scrambling sequence generation apparatus performs self-service by automatically adapting to sensing requirements without requiring external control. The device uses its own internal resources to process sensing information and generate appropriate scrambling sequences, eliminating the need for additional dedicated sensing processing units.
