Communication Apparatus Power Priority Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication techniques face challenges in stabilizing power supply between devices, leading to battery depletion in secondary terminals when higher priority devices require power for function usage, as seen in scenarios where printing apparatuses are used for both charging and data transmission.
Innovation Solution
A communication apparatus with a power transmission unit and a communication unit that receives use requests, acquires identifiers to determine whether to transmit power, ensuring that devices requesting power for function usage are prioritized, allowing stable power supply and function completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If power is supplied to a terminal apparatus requesting charging before function usage, then the charging function is occupied and power is supplied to the terminal apparatus, but a second terminal apparatus requiring power for function usage cannot receive power and its battery may run out
Solution Approach 1:
The printing apparatus performs preliminary identification of terminal apparatuses and their request purposes before power supply. By acquiring identification information and determining the purpose (charging vs. function usage) in advance, the system prioritizes terminals needing power for function usage, ensuring their battery does not run out during critical operations.
Solution Approach 2:
The system changes the parameter of power supply priority based on the determined purpose of the terminal apparatus. Terminals requesting power for function usage are assigned higher priority than those requesting only charging, dynamically adjusting power allocation parameters to ensure critical functions are not interrupted.
2Ease of operation
If the printing apparatus prioritizes charging function for connected terminals, then charging is provided to terminals, but terminals requiring power for printing function cannot operate reliably
Solution Approach 1:
The printing apparatus uses identification information as an intermediary to mediate between charging requests and function usage requests. By acquiring and comparing identification information, the system determines the true purpose of each terminal and makes informed power supply decisions that balance charging availability with printing function reliability.
Solution Approach 2:
The system performs preliminary determination of terminal purposes before power supply allocation. By identifying terminals and determining whether they need power for charging or function usage in advance, the system ensures that printing operations can complete reliably while still providing charging services to appropriate terminals.
3Adaptability or versatility
If power transmission is performed without identifying the purpose of power request, then power can be supplied to any terminal, but the system cannot ensure power priority for critical functions
Solution Approach 1:
The printing apparatus implements feedback by acquiring identification information from terminal apparatuses and using this information to determine the purpose of power requests. This feedback mechanism enables the system to adjust power supply decisions dynamically, ensuring that terminals requiring power for critical functions receive priority while maintaining flexible power supply to other terminals.
Data Source
AI summary
A communication apparatus receives a use request to use a function of the communication apparatus from an external device via a communication unit. When the use request is received, the communication apparatus acquires a first identifier for identifying the external device as a request source which requests the use of the function. Based on the acquired first identifier and a second identifier for identifying an external device which requests power supply by a power transmission unit, the communication apparatus determines whether to cause the power transmission unit to transmit power to the external device. If it is determined to transmit power, the communication apparatus transmits, via the power transmission unit, power to the external device which requests power supply.
