Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a photovoltaic device is located remotely to absorb a large amount of solar light, then the power generation capacity is improved, but the difficulty of monitoring and managing the device state increases
Solution Approach 1:
A data logger serves as an intermediary device that collects state information from multiple sensing units (temperature, humidity, illumination sensors) and transmits it to external terminals. This mediator enables remote monitoring of photovoltaic devices located in hard-to-reach areas, solving the contradiction between remote placement for power generation and ease of monitoring.
2Device complexity
If state information is transmitted without time stamps, then the data transmission process is simplified, but the accuracy of performance analysis and fault detection decreases
Solution Approach 1:
The data logger automatically adds time stamps to state information before transmission. This preliminary action of timestamping ensures that performance analysis and fault detection can accurately correlate events in time, improving measurement precision without significantly increasing transmission complexity.
3Reliability
If multiple sensing units operate simultaneously to record device state, then the comprehensiveness of monitoring is improved, but the complexity of data management increases
Solution Approach 1:
The data logger merges data from multiple sensing units (temperature sensor, humidity sensor, illumination sensor) into a unified data stream with centralized time stamping and management. This combining approach maintains comprehensive monitoring reliability while simplifying data management through centralized processing.
