Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If discovery resources are allocated using traditional broadcast methods, then the system is simple to implement, but the utilization rate of discovery resources is low due to collisions
Solution Approach 1:
The patent implements dynamic resource allocation by enabling the base station to adjust discovery resource parameters in real-time based on collision feedback from user equipment. The system transitions from static broadcast-based allocation to a dynamic feedback-driven mechanism where resource configuration is continuously optimized according to actual usage conditions, thereby improving utilization rate while maintaining implementation simplicity.
Solution Approach 2:
The patent introduces a feedback mechanism where user equipment reports collision information to the base station, which then uses this information to adjust discovery resource allocation. This closed-loop feedback system enables the base station to identify and resolve collision issues, optimize resource distribution, and improve overall utilization rate without complicating the system architecture.
2Reliability
If discovery resources are increased to reduce collisions, then discovery performance improves, but resource waste increases when resources are not fully utilized
Solution Approach 1:
The patent dynamically adjusts discovery resource parameters such as time frequency resources and reuse factors based on real-time collision statistics and utilization data. By continuously optimizing these parameters, the system achieves reliable discovery performance while minimizing resource waste, preventing both under-utilization and over-provisioning of discovery resources.
Solution Approach 2:
The system implements dynamic adjustment of discovery resource configuration based on actual network conditions. The base station monitors collision rates and utilization patterns, then dynamically modifies resource allocation to match actual demand, ensuring optimal balance between discovery performance and resource efficiency without fixed, static allocations.
3Productivity
If the base station monitors and adjusts resources dynamically, then utilization rate improves, but system complexity increases
Solution Approach 1:
The patent employs a feedback mechanism where user equipment autonomously reports collision information to the base station. This feedback approach enables dynamic resource optimization without requiring complex centralized control, as the base station simply processes feedback signals and adjusts resources accordingly, maintaining relatively simple system architecture while improving utilization.
Solution Approach 2:
The system implements self-service mechanisms where user equipment automatically detects and reports collision conditions, and the base station autonomously adjusts resource allocation based on this feedback. This self-managing approach reduces the need for complex external control systems while achieving dynamic optimization of discovery resource utilization.
