Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wired electrical power or battery recharging is used, then devices can be powered, but movement is constricted and manual recharging requires mechanical connections that are unreliable and prone to failure
Solution Approach 1:
The patent replaces mechanical wired connections with wireless electromagnetic field-based power transmission. The system uses a power delivery module with transmit coils to wirelessly transmit power to receive coils in the device, eliminating mechanical plugs and connectors that are unreliable and prone to failure.
Solution Approach 2:
The patent implements autonomous charging capability where the device can automatically recharge itself without human intervention. The power delivery module and battery management system work together to enable self-service charging, reducing the need for manual recharging operations.
2Duration of action of moving object
If batteries are recharged multiple times, then usable lifetime decreases due to charge cycle degradation
Solution Approach 1:
The patent incorporates a battery management system with logic capabilities that monitors battery charge cycles and provides feedback to optimize charging parameters. This feedback mechanism helps manage battery degradation by adjusting charging rates and patterns based on battery health status, extending usable lifetime.
Solution Approach 2:
The system performs preliminary assessment of battery status before charging to determine optimal charging parameters. The battery management system evaluates battery health and charge cycle count in advance, then adjusts charging strategy accordingly to minimize degradation and extend battery life.
3Extent of automation
If smart batteries with logic and communication capabilities are integrated, then battery management and autonomous operation improve, but device complexity increases
Solution Approach 1:
The patent merges the battery management system, communication module, and power management logic into an integrated smart battery unit. This consolidation provides automation capabilities while managing complexity through integration rather than separate components.
Solution Approach 2:
The smart battery is designed with multi-functionality, serving as both power storage and intelligent control unit. It handles power management, communication, and autonomous charging decisions, reducing the need for separate dedicated components and managing overall system complexity.
