Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power is shared between multiple components, then device functionality is improved, but power reliability deteriorates due to limited power supply
Solution Approach 1:
The system dynamically adjusts power allocation between components based on real-time power availability and component priorities. The power management circuit continuously monitors power conditions and automatically reconfigures power distribution, enabling the system to adapt to varying power supply conditions while maintaining critical functions.
Solution Approach 2:
The system changes operational parameters of components based on power availability. When power is limited, the system adjusts voltage levels, current allocation, and operational modes of components to ensure reliable operation within available power constraints, eliminating the need for additional batteries.
2Power
If additional power is drawn from power source, then power sharing capability is improved, but power circuit complexity increases
Solution Approach 1:
A power management circuit acts as an intermediary between the power source and multiple components. This intermediary intelligently controls current flow and voltage distribution, automatically drawing additional power when needed and allocating it to appropriate components, thereby simplifying the overall system architecture while enhancing power sharing capability.
3Use of energy by moving object
If battery is used for additional power, then power availability is improved, but system reliability deteriorates in extreme weather
Solution Approach 1:
The invention extracts and eliminates the battery component from the system by implementing intelligent power management that draws additional power directly from the existing power source when needed. This removal of the battery eliminates the reliability issues associated with battery performance in extreme weather conditions while maintaining adequate power availability through dynamic power allocation.
