Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If wind and photovoltaic power sources are used to power base stations, then carbon emissions are reduced and sustainable operation is promoted, but operation reliability deteriorates due to weather dependence
Solution Approach 1:
The power supply system is segmented into multiple independent components: wind power source, photovoltaic power source, battery storage system, and grid connection. Each component can operate independently or in combination, ensuring that failure of one source does not compromise overall system reliability while maintaining sustainable operation through renewable energy segments.
2Object-generated harmful factors
If base stations are powered by renewable energy sources, then environmental sustainability is improved, but operational stability deteriorates due to weather condition dependence
Solution Approach 1:
Multiple power generation technologies (wind and photovoltaic) are merged into a single hybrid power system, along with battery storage and grid connection. This combination diversifies the power sources so that when one source is unavailable due to weather conditions, other sources can compensate, maintaining stable power supply while preserving environmental sustainability benefits.
3Object-generated harmful factors
If base stations operate independently from commercial power grids using renewable sources, then sustainability is improved, but power availability deteriorates during adverse weather conditions
Solution Approach 1:
Battery storage systems are charged in advance during periods of favorable weather conditions when renewable energy generation is high. This preliminary energy accumulation ensures that sufficient power is available during adverse weather conditions when generation is low, maintaining both sustainability and power availability without requiring continuous grid connection.
