Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply control systems for information processing devices can only enable or disable battery units based on identification and predetermined conditions, failing to effectively manage power supply based on the combination of connected power supply apparatuses, limiting the ability to control power feeding and charging accordingly.
Innovation Solution
An information processing apparatus with connection units for power supply apparatuses, a connection state determination unit, a power supply identification information acquisition unit, and a power supply control unit that manages and controls power supply based on the type of connected power supply apparatuses, allowing for dynamic control of power feeding and charging by acquiring and managing power supply type information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing power supply control technology is used to enable or disable battery units based on identification information, then authorized battery units can be made available and unauthorized ones disabled, but the system cannot control power feeding and charging based on the combination of connected power supply apparatuses
Solution Approach 1:
The patent applies dynamics by making the power supply control system adaptable to different connection states. The control unit dynamically adjusts power feeding and charging operations based on real-time detection of which power supply apparatuses (battery unit, AC adapter, etc.) are connected. This allows the system to transition between different operational modes (e.g., charging only, power feeding only, or both simultaneously) according to the specific combination of connected apparatuses, thereby achieving versatile control without permanently increasing structural complexity.
2Reliability
If the system only enables or disables power supply apparatuses based on identification information, then security is maintained, but the ability to realize feeding from connected power supply apparatuses based on their combination is lost
Solution Approach 1:
The patent implements feedback by continuously monitoring the connection states of multiple power supply apparatuses and using this information to adjust control decisions. The control unit receives feedback about which apparatuses are connected (battery unit, AC adapter, or both) and responds by appropriately enabling or disabling power feeding and charging operations. This feedback mechanism maintains security through identification verification while simultaneously enabling flexible adaptation to different connection combinations.
3Productivity
If the system acquires and manages power supply type information from multiple connected apparatuses, then optimal power control is achieved, but the complexity of information management increases
Solution Approach 1:
The patent applies universality by designing a control unit that performs multiple functions: it acquires identification information, determines connection states, manages power supply type information, and controls both power feeding and charging operations. This multi-functional approach consolidates what could be separate complex subsystems into a single integrated control unit, thereby achieving efficient power supply control while minimizing the increase in overall system complexity.
