Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing 5G communication systems use conventional random access configuration, then conventional terminal equipment can communicate, but terminal equipment with medium and low capabilities cannot be supported due to high complexity and processing capability requirements
Solution Approach 1:
The patent segments the random access configuration into two distinct types: first random access configuration information for unconventional terminals (medium and low capability) and second random access configuration information for conventional terminals. This segmentation allows the system to provide differentiated configuration levels, enabling support for terminals with varying capabilities without requiring all terminals to handle the most complex configuration protocols.
Solution Approach 2:
The patent applies local quality by providing different configuration parameters and processing requirements for different terminal types. Unconventional terminals receive simplified configuration with lower complexity requirements, while conventional terminals receive full configuration. This localized differentiation of quality levels allows the system to optimize for specific terminal capabilities without compromising overall system performance.
2Productivity
If conventional 5G terminal equipment is used, then high performance communication is achieved, but cost increases and widespread deployment is limited
Solution Approach 1:
The patent implements partial action by providing only the necessary configuration level for each terminal type. Unconventional terminals receive partial configuration information sufficient for their capabilities, while conventional terminals receive complete configuration. This approach avoids over-engineering the system for high-performance terminals when supporting cost-sensitive deployments, thereby reducing manufacturing complexity and deployment costs while maintaining adequate performance for each segment.
3Ease of manufacture
If differentiated configuration is implemented for unconventional terminals, then cost is reduced and deployment is enhanced, but system complexity for configuration management increases
Solution Approach 1:
The patent applies universality by creating a unified random access procedure that handles both unconventional and conventional terminals through a single framework. The network device uses the same random access channel and procedure structure, but differentiates configuration based on terminal type. This multi-functional approach allows the system to manage different terminal capabilities within a single configuration management mechanism, avoiding the need for separate management systems.
