Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If multiple batteries are used to extend operation time, then the working time of mobile robot is improved, but the charge amount of each battery becomes uneven leading to complete discharge and reduced battery life
Solution Approach 1:
The system pre-establishes discharge scenarios and determines discharge intervals for each battery before actual operation. The processor predicts charge amounts at future time points and determines discharge strategies in advance, preventing complete discharge and extending battery life while maximizing working time.
Solution Approach 2:
The discharge strategy is dynamically adjusted based on real-time charge levels and predicted future states. The processor continuously monitors charge amounts, determines which battery to discharge next based on predefined intervals, and switches between batteries dynamically to maintain optimal charge levels and prevent complete discharge.
2Duration of action of moving object
If batteries are discharged completely to maximize operation time, then the working time is extended, but the battery life decreases rapidly
Solution Approach 1:
The system pre-establishes discharge scenarios and determines discharge intervals for each battery before actual operation. The processor predicts charge amounts at future time points and determines discharge strategies in advance, preventing complete discharge and extending battery life while maximizing working time.
Solution Approach 2:
The processor continuously monitors the charge amounts of all batteries and uses this feedback to determine which battery to discharge next. Based on the monitored charge levels and predicted future states, the system adjusts the discharge strategy to prevent complete discharge, thereby extending battery life while maintaining maximum operation time.
3Device complexity
If a single battery is used to simplify management, then the device complexity is reduced, but the operation time is limited
Solution Approach 1:
The battery system is segmented into multiple independent batteries, each with its own discharge scenario and interval. The processor manages multiple batteries by dividing the discharge operation into segments, where each battery is discharged according to its specific interval and scenario, thereby extending total operation time while maintaining manageable complexity through structured segmentation.
4Reliability
If batteries are switched frequently to maintain charge levels, then the battery life is extended, but the operation time may be reduced due to switching overhead
Solution Approach 1:
The system pre-establishes discharge scenarios and determines discharge intervals for each battery before actual operation. By predicting charge amounts at future time points and determining discharge strategies in advance, the system minimizes unnecessary switching while preventing complete discharge, thereby extending battery life without sacrificing operation time.
Solution Approach 2:
The discharge strategy is dynamically adjusted based on real-time charge levels and predicted future states. The processor continuously monitors charge amounts, determines which battery to discharge next based on predefined intervals, and switches between batteries dynamically to maintain optimal charge levels, balancing battery life extension with continuous operation.
