Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the electronic device performs beam searching and measurement at regular intervals, then the beam direction can be determined based on signal strength, but the device cannot form an optimal beam pair link at a desired time point due to time limitations
Solution Approach 1:
The electronic device performs beam searching and measurement in advance before the desired communication time point. The processor stores measurement results and beam information in memory, so when communication is needed, the pre-measured beam data can be immediately used without waiting for the next regular measurement interval, thus resolving the time limitation while maintaining measurement accuracy
Solution Approach 2:
The device dynamically adjusts its operation mode between measurement phases and communication phases. During measurement phase, the device performs comprehensive beam searching and stores results. During communication phase, it uses the pre-stored beam information. This dynamic switching allows the device to have optimal beam pairs ready at any desired time point without continuous measurement, resolving the contradiction between measurement precision and time loss
2Reliability
If the electronic device measures beam strength in multiple directions, then it can find optimal beam pair links, but the complexity of beam searching increases
Solution Approach 1:
The processor segments the beam searching process into multiple independent measurement operations, where each measurement focuses on a specific direction or beam candidate. By dividing the complex multi-directional beam search into simpler, manageable measurement tasks, the device can systematically evaluate multiple directions without overwhelming complexity, maintaining reliable beam pair link quality while making the searching process more tractable
Solution Approach 2:
The device changes measurement parameters such as the number of measurements to perform and the threshold for beam selection. By adjusting these parameters, the device can balance between thoroughness of beam searching (measuring more directions) and complexity management (setting reasonable thresholds to stop searching early when good beams are found). This allows finding optimal beam pairs while controlling the complexity of the searching process
