Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If lithium batteries are used with high energy density, then energy storage capacity is improved, but safety hazards and handling complexity increase
Solution Approach 1:
The battery system is divided into modular battery packs that can be independently handled and replaced. Each pack contains multiple cells organized in series strings, allowing the system to maintain high total energy capacity while keeping individual replacement units safe and manageable.
Solution Approach 2:
A battery management system (BMS) acts as an intermediary between the high-energy-density battery cells and the user/application. The BMS monitors cell voltages, temperatures, and states of charge, preventing unsafe conditions while enabling the use of high-capacity lithium cells.
2Adaptability or versatility
If battery systems are customized for specific applications, then performance is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent creates a universal battery pack design with standardized mechanical dimensions, electrical connectors, and communication interfaces. These standardized packs can be used across multiple applications (e-bikes, scooters, motorcycles) without customization, reducing manufacturing complexity while maintaining adaptability through software configuration.
Solution Approach 2:
The battery management system dynamically adapts to different applications through software configuration rather than hardware customization. The same physical battery pack can be optimized for different voltage requirements, power demands, and usage patterns through programmable control parameters.
3Reliability
If individual battery cells are monitored and matched, then battery lifetime and reliability are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The battery management system automatically performs cell monitoring, voltage balancing, and state estimation without external intervention. The system self-regulates by directing charging current to specific cells based on their individual states, eliminating the need for manual cell matching during assembly or maintenance.
Solution Approach 2:
The BMS continuously monitors individual cell voltages and temperatures, providing real-time feedback to adjust charging currents and prevent unsafe conditions. This closed-loop control automatically compensates for cell variations, extending battery life without requiring complex manual intervention.
4Duration of action of stationary object
If battery systems are designed for long lifetime, then durability is improved, but adaptability and ease of replacement worsen
Solution Approach 1:
The battery system is segmented into replaceable modular packs rather than a fixed integrated design. Users can quickly swap entire packs without tools or complex procedures, while the BMS ensures long-term reliability through continuous monitoring and cell balancing during normal operation.
Solution Approach 2:
The system dynamically manages battery health during use through active cell monitoring and balancing, extending the operational lifetime of each pack. Simultaneously, the modular design enables rapid replacement when needed, providing both long duration and high adaptability.
