Dual Power Supply Switching for POS Terminal Startup Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-contact power supplies often fail to provide sufficient power for information processing apparatuses due to high inrush currents during startup, leading to failure in initiating the operation of devices like POS terminals.
Innovation Solution
An information processing apparatus is designed with both wired and non-contact power supply connectors, where the processor selects the power source based on the operation state, ensuring that wired power is used at startup and non-contact power is utilized once stability is confirmed, thereby minimizing inrush current consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If non-contact power supply is used to provide electric power without power cable, then ease of operation is improved, but reliability deteriorates due to insufficient power during startup
Solution Approach 1:
The patent applies dynamics by making the power supply mode changeable based on operational state. The system dynamically switches between non-contact power supply mode during normal operation and wired power supply mode during startup or when instability is detected, allowing the power supply characteristics to adapt to different operational phases and resolve the contradiction between ease of operation and reliability.
Solution Approach 2:
The patent changes the power supply parameters by switching between two distinct power supply modes (non-contact and wired) based on operational conditions. This parameter change allows the system to utilize the convenience of non-contact power supply during stable operation while ensuring reliable startup through wired power supply, thereby resolving the contradiction.
2Ease of operation
If non-contact power supply is used, then ease of operation is improved, but power consumption worsens due to high inrush current consuming most supplied power
Solution Approach 1:
The system dynamically adjusts power supply mode based on operational state, using wired power supply during startup when inrush current occurs and switching to non-contact power supply after stability is confirmed. This dynamic adaptation prevents excessive power consumption during critical startup phases while maintaining the ease of operation benefit during normal operation.
Solution Approach 2:
The patent applies preliminary action by using wired power supply in advance during the startup phase before switching to non-contact power supply. This preliminary use of wired power ensures that the system can handle the high inrush current requirements during initialization, preventing power consumption issues before they occur.
3Adaptability or versatility
If wired power supply connector and non-contact power supply connector are both provided, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the information processing apparatus with dual power supply capability, allowing it to function with either wired or non-contact power supply depending on operational needs. This multi-functionality enables the system to adapt to different power supply scenarios while the control logic manages the complexity of coordinating between the two power supply modes.

AI summary
An information processing apparatus includes a wired electric power supply connector configured for connection with a wired electric power supply to receive electric power therefrom, non-contact electric power supply connector configured for electric coupling with a non-contact electric power supply to receive electric power therefrom, and a processor. The processor selects, for electric power supplied to each component of the information processing apparatus, one of the wired electric power supply and the non-electric power supply, wherein the wired electric power supply is selected at a time of startup of the information processing apparatus, and the non-contact electric power supply is selected if an operation state of the information processing apparatus or the non-contact power supply meets a predetermined condition. The processor controls the wired electric power supply connector and the non-contact electric power supply connector to supply electric power to each component based on the selection.
