Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If movable batteries are classified into groups based on charging rates and controlled across multiple stations, then the efficiency of battery resource utilization is improved, but the system complexity increases

Engineering Contradiction:
Improvebattery resource utilization efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system segments movable batteries into different groups based on their charging rates (first group with first charging rate, second group with second charging rate). This segmentation allows the system to manage batteries with different characteristics separately, optimizing charging strategies for each group while improving overall resource utilization efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system designates certain stations as transferable stations that can handle multiple functions: charging batteries, transferring batteries between groups, and managing power consumption. This multi-functionality reduces the need for specialized infrastructure and improves battery resource utilization across the network.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If batteries are transferred between groups based on power consumption prediction, then the response to power demand is improved, but the control complexity increases

Engineering Contradiction:
Improveresponse to power demandVSAvoidcontrol complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system performs preliminary classification of movable batteries into groups based on their charging rates before power consumption occurs. This advance organization allows for efficient power demand response, as batteries are already positioned in appropriate groups for their charging characteristics, reducing the need for complex real-time control decisions.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses power consumption prediction as feedback to dynamically transfer batteries between groups. The control unit monitors predicted power consumption and automatically transfers batteries from the first group to the second group or vice versa, creating a closed-loop control system that adapts to power demand while maintaining manageable complexity through automated decision-making.

Inventive Principle:
Principle #23Feedback

3Reliability

If the system controls charging and discharging operations across multiple stations, then the power network stability is improved, but the operational complexity increases

Engineering Contradiction:
Improvepower network stabilityVSAvoidoperational complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system implements dynamic control of charging and discharging operations at transferable stations. The control unit can flexibly adjust battery operations based on real-time power consumption predictions and grid conditions, allowing the system to respond to changing power network requirements while maintaining stability through automated, adaptive control rather than rigid operational procedures.

Inventive Principle:
Principle #15Dynamics
