Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a high-capacity battery is incorporated to withstand extended use, then the battery capacity is improved, but the size and weight of the electronic device become large
Solution Approach 1:
The battery system is divided into multiple independent battery units (first battery in CPU, second battery in display portion, third battery in touch input portion) instead of using a single large battery. This segmentation allows the device to achieve extended operational duration through selective activation and power management while keeping individual battery units small and lightweight.
2Volume of moving object
If the electronic device is reduced in size and thickness, then the portability is improved, but the battery capacity is reduced
Solution Approach 1:
Multiple small battery units are distributed throughout the device structure (in CPU, display, touch input portions) rather than requiring a single large battery. This enables the device to maintain a compact form factor while achieving high effective capacity through selective power usage and power sharing between units.
Solution Approach 2:
Each battery unit serves multiple functions: it can power its local component, share power with other components when needed, and be recharged wirelessly. The power management circuit enables any battery to serve as a power source for any component, maximizing the utility of the distributed battery system within the limited volume.
3Adaptability or versatility
If multiple batteries are provided in different components, then the power management flexibility is improved, but the device complexity increases
Solution Approach 1:
The power management circuit implements a universal power sharing architecture where any battery can power any component through wireless power transmission. This standardized multi-functional approach simplifies the control logic compared to dedicated power management for each battery-component pair, as the system uses a common protocol for power sharing among all units.
Solution Approach 2:
Each battery unit includes its own wireless charging capability and can independently manage its charge state. The power management circuit automatically monitors battery levels and facilitates power sharing without complex external control, allowing the system to self-regulate power distribution based on real-time battery states.
4Power
If batteries are charged or discharged, then the power supply function is provided, but heat generation occurs that might thermally influence the surroundings
Solution Approach 1:
The power generation function is distributed across multiple small battery units rather than concentrated in a single large battery. This segmentation naturally distributes heat generation throughout the device structure, preventing localized thermal buildup and reducing the overall thermal influence on surrounding components.

Implementation Method 1
The first receiving portion has a function of wirelessly charging the first battery. The second receiving portion has a function of wirelessly charging the second battery.
Implementation Method 2
The power management circuit has a function of wirelessly transmitting power of one of the first battery and the second battery to the other so that the battery is charged.
