Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a particular unit with high battery usage performs operations continuously, then the operational capability is maintained, but the battery lifespan of that unit is shortened
Solution Approach 1:
The patent implements dynamic operation mode switching between multiple units based on real-time battery state monitoring. The system automatically transitions from a static assignment model to a dynamic load-balancing model where operational responsibilities are redistributed according to each unit's battery health status, usage patterns, and charge levels. This dynamic adaptation allows the system to maintain productivity while preventing any single unit from being overused to the point of battery degradation.
Solution Approach 2:
The system monitors and responds to changes in battery parameters such as charge level, usage duration, and operational cycles. By detecting when a unit's battery parameters indicate high usage or low charge, the system changes operational parameters by switching the active unit, thereby distributing wear and extending overall system reliability without compromising productivity.
2Productivity
If one unit is used extensively, then operational tasks are completed efficiently, but uneven battery discharge occurs across units
Solution Approach 1:
The system employs dynamic load distribution that continuously adjusts which unit performs operations based on real-time battery state assessment. This prevents static imbalances where one unit would consistently drain faster, by actively monitoring discharge patterns and redistributing operational loads to maintain uniform battery consumption across all units over time.
Solution Approach 2:
The patent implements a feedback mechanism where battery state information from each unit is continuously monitored and fed back to the control system. Based on this feedback regarding charge levels and usage patterns, the system adjusts operational assignment to achieve balanced discharge across units, ensuring that no single unit is consistently overused while maintaining overall task completion efficiency.
3Reliability
If battery state monitoring and operation mode determination are implemented, then battery lifespan is extended, but device complexity increases
Solution Approach 1:
The patent integrates battery monitoring and operation mode determination functions into existing system components, allowing these components to serve multiple purposes. The processor that manages basic device operations is also utilized for monitoring battery states and determining operation modes, eliminating the need for separate dedicated hardware and reducing overall system complexity while still achieving extended battery lifespan through intelligent management.
Solution Approach 2:
The system performs self-monitoring and self-adjustment regarding battery usage without requiring external intervention or complex user configuration. Each unit autonomously reports its battery state, and the control system automatically determines optimal operation modes based on this information, reducing the need for additional management infrastructure and keeping the system relatively simple while effectively extending battery lifespan.
