Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the fan rotation speed is increased to reduce battery temperature, then the cooling effect is improved, but the noise level increases and causes disturbance to nearby residents
Solution Approach 1:
The patent implements dynamic fan speed control by switching between multiple evaluation rules based on environmental conditions. The system dynamically adjusts fan rotation speed not just based on temperature but also considering location type (residential vs. non-residential) and ambient noise levels, thereby resolving the contradiction between cooling effectiveness and noise generation
Solution Approach 2:
The system changes the control parameters from a single temperature-based rule to multiple evaluation rules that incorporate location attributes and ambient sound levels. By changing the parameter set used for decision-making, the system can select appropriate fan speeds that balance cooling needs with noise constraints in different environments
2Object-generated harmful factors
If the fan rotation speed is controlled to reduce noise in residential areas, then the noise disturbance is reduced, but the cooling effectiveness may be compromised
Solution Approach 1:
The system uses feedback from multiple sensors (temperature sensors, sound receiving units) and external data (location information) to continuously monitor conditions and adjust fan speed accordingly. This feedback mechanism ensures that cooling effectiveness is maintained while adapting to noise constraints in residential areas
3Adaptability or versatility
If multiple fan rotation speed evaluation rules are implemented based on location and ambient sound, then the adaptability to different environments is improved, but the system complexity increases
Solution Approach 1:
The control system is segmented into multiple evaluation rules, each optimized for specific environmental conditions (residential areas, non-residential areas, different ambient noise levels). This segmentation allows the system to handle different scenarios with dedicated rules while maintaining overall simplicity through modular rule-based architecture

AI summary
A fan rotation speed control method for a battery energy station (100) is applicable to the battery energy station (100) for storing and charging plural batteries (112). A first and a second fan rotation speed evaluation rules (142, 144), which are different, are provided, wherein the first and the second fan rotation speed evaluation rules (142, 144) each define a corresponding fan rotation speed at at least one temperature. A temperature is detected using a temperature sensor (120). The battery energy station (100) controls a rotation speed of at least one fan (130) according to the temperature and the first fan rotation speed evaluation rule (142). The battery energy station (100) determines whether a preset condition is met. When the preset condition is met, the battery energy station (100) controls the rotation speed of the fan (130) according to the temperature and the second fan rotation speed evaluation rule (144).
