Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple receiving blocks are provided for simultaneous carrier demodulation, then the capability to receive multiple carriers is improved, but the efficiency of hardware resource utilization deteriorates when some carriers cannot be received
Solution Approach 1:
The receiving blocks are designed to perform multiple functions: they can simultaneously demodulate multiple carriers when all are available, and switch to receiving a single carrier with higher signal strength when some carriers are unavailable. The control unit dynamically assigns different functions to the same hardware resources based on reception conditions, making the receiving blocks universal rather than dedicated to specific carriers.
Solution Approach 2:
The system dynamically adjusts the operation mode of receiving blocks based on real-time signal strength detection. The control unit monitors signal conditions and dynamically reconfigures which receiving blocks are active and what frequencies they receive, transitioning between parallel demodulation mode and selective reception mode to optimize hardware utilization under varying conditions.
2Productivity
If receiving blocks continue to operate at frequencies with undetected signal strength, then hardware resources remain utilized, but ineffective processing and energy waste occur
Solution Approach 1:
The system implements feedback through signal strength detection by the control unit, which continuously monitors the quality of received signals. When the control unit detects that signal strength at a particular frequency is below a threshold or undetected, it provides feedback to stop the receiving block from processing that frequency, thereby preventing energy waste on ineffective operations while maintaining hardware readiness for other frequencies.
Solution Approach 2:
The receiving blocks are designed to self-adjust their operation based on control unit directives. When signal strength detection indicates poor reception, the receiving blocks automatically switch to receiving at alternative frequencies assigned by the control unit, eliminating the need for external intervention and ensuring continuous effective operation without energy waste.
3Reliability
If receiving blocks switch to receive at the same frequency when signal strength is not detected, then space diversity efficiency is improved, but coordination control complexity increases
Solution Approach 1:
The control unit consolidates the control of multiple receiving blocks into a single centralized entity. When signal strength detection indicates that one receiving block is not detecting a predetermined signal strength, the control unit simultaneously directs multiple receiving blocks to receive at the same frequency, coordinating their operation through unified control logic that manages frequency assignment and switching for all blocks.
