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 patent divides the single high-capacity battery into multiple small-capacity batteries distributed across different components (CPU module, display module, touch input module). Each module has its own battery, allowing the device to achieve extended operational duration through selective power management while keeping individual battery weights low, thus resolving the contradiction between battery capacity and device weight.
2Volume of moving object
If the device size is reduced to improve portability, then the device compactness is improved, but the battery capacity is reduced
Solution Approach 1:
The patent segments the battery system into multiple small batteries integrated within different modules, allowing the device to maintain a compact overall volume while collectively providing sufficient total battery capacity. The distributed architecture enables efficient space utilization and selective power consumption, resolving the contradiction between device compactness and battery capacity.
Solution Approach 2:
Each module is equipped with its own battery and power management capabilities, allowing local power supply optimization. This enables the device to maintain compact dimensions while ensuring each component has adequate power capacity for its specific functions, resolving the contradiction between device volume and battery capacity.
3Volume of moving object
If multiple small batteries are used to reduce device size, then the device compactness is improved, but the power consumption management becomes more complex
Solution Approach 1:
Each module is equipped with its own power management circuit that autonomously manages its local battery, enabling independent power supply and consumption control. This self-service approach simplifies overall power management by distributing control functions to individual modules, reducing the complexity burden on the central system while maintaining efficient power utilization across the device.
Solution Approach 2:
The power management circuit is designed with universal functionality to handle multiple power sources and enable power transmission between any modules. This multi-functional design simplifies the overall power management architecture by providing a standardized interface for battery management, wireless charging, and inter-module power transmission, resolving the contradiction between device compactness and power management complexity.
4Use of energy by moving object
If selective battery driving is implemented to save power, then the power consumption is reduced, but the system complexity increases
Solution Approach 1:
Each module's power management circuit autonomously controls its local battery and can independently select when to activate or deactivate based on operational needs. This self-service capability enables selective battery driving without requiring complex centralized control logic, reducing power consumption while minimizing the increase in system complexity.
Solution Approach 2:
The power management circuit incorporates universal control functionality that can manage multiple batteries and enable selective activation of different modules. This multi-functional design allows the system to achieve power savings through selective battery driving while maintaining relatively simple system architecture through standardized power management interfaces.
