Power Supplying Apparatus Automatic Power Role Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face a significant burden in manually confirming and setting the desired direction of power flow between a power supplying apparatus and an external device each time they are connected.
Innovation Solution
A power supplying apparatus equipped with a CPU, memory, and a storage unit that stores power flow direction information, allowing automatic matching of power roles based on pre-stored information when an external apparatus is connected, reducing user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user manually confirms and sets the power flow direction each time the apparatus is connected, then the user can ensure the desired power role is assigned, but the user burden and operation time increase significantly
Solution Approach 1:
The power supplying apparatus automatically determines and assigns its own power role based on stored preference information without requiring user confirmation. The control unit reads the stored power flow direction information and autonomously configures the power supply mode, eliminating the need for manual user intervention while maintaining reliable power role assignment.
Solution Approach 2:
The apparatus stores power flow direction information in advance based on previous user preferences or automatic determinations. When connected to an external apparatus, the system retrieves this pre-stored information to quickly assign the appropriate power role, avoiding repeated manual confirmation and reducing operation time while maintaining accuracy.
2Reliability
If the user manually confirms and sets the power flow direction each time, then the desired power role can be ensured, but the operation time and frequency of user intervention increase
Solution Approach 1:
The system performs preliminary determination of power flow direction by storing preference information during initial connections or based on apparatus characteristics. This pre-stored information enables rapid power role assignment upon subsequent connections, significantly reducing operation time while maintaining reliable power role assignment through the control unit's automated selection process.
3Ease of operation
If automatic power role matching is implemented using stored information, then user burden and operation time are reduced, but the system complexity increases due to storage and control logic
Solution Approach 1:
The control unit automatically manages power role assignment by reading from and writing to the storage unit based on connection history and apparatus characteristics. This self-service mechanism eliminates complex user interfaces for power role selection while maintaining simple overall system architecture, as the automation logic is integrated into the existing control structure rather than adding separate complex subsystems.
4Loss of time
If automatic power role matching is implemented, then operation time is reduced, but the system requires additional storage and control logic components
Solution Approach 1:
The storage unit and control unit serve multiple functions: they store and process power flow direction information for automatic power role assignment, while also managing other apparatus operations. This multi-functionality approach minimizes additional hardware requirements, as existing control and storage infrastructure is utilized for the automated power role determination rather than adding dedicated separate components.

AI summary
A power supplying apparatus stores power flow direction information related to a power role of the power supplying apparatus relative to an external apparatus in a storage, and performs control, in a case where the external apparatus has been connected to a connecter of the power supplying apparatus, to match a power role of the power supplying apparatus and a power role corresponding to the power flow direction information stored in the storage based on the power flow direction information stored in the storage unit.
