Dynamic Wireless Priority Control for Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image forming apparatuses with multiple wireless communication units, prioritizing one communication method over others can restrict usage of other units, leading to potential delays or failure in data acquisition using the desired communication method.
Innovation Solution
An image forming apparatus with a prioritized control unit that manages Wi-Fi and BLE communication units based on destination information, allowing dynamic switching between communication methods to prioritize real-time data acquisition and user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication of one wireless communication unit is prioritized at all times over other wireless communication units, then communication reliability for the prioritized unit is improved, but communication flexibility and user choice are restricted
Solution Approach 1:
The patent implements dynamic priority switching for wireless communication units based on real-time communication states. The control unit determines whether to prioritize first or second wireless communication units by evaluating communication establishment status, data transmission status, and user presence information. This dynamic adjustment allows the system to adapt priority levels according to actual communication needs rather than maintaining a fixed priority structure, thereby resolving the contradiction between reliability and flexibility.
2Device complexity
If a fixed priority system is used for multiple wireless communication units, then system control complexity is reduced, but response time to user communication needs increases
Solution Approach 1:
The patent employs feedback mechanisms where the control unit continuously monitors communication establishment status, data transmission status, and user presence information from multiple wireless communication units. Based on this real-time feedback, the system dynamically adjusts priority levels to ensure timely response to user communication needs. This feedback-driven approach maintains relatively simple control logic while significantly improving response time compared to fixed priority systems.

AI summary
An image forming apparatus includes a first wireless communication unit that performs wireless communication based on a first wireless communication method, a second wireless communication unit that performs wireless communication based on a second wireless communication method different from the first wireless communication method, and a prioritized control unit that performs a control based on information related to a communication destination of the first wireless communication unit and information related to a communication destination of the second wireless communication unit such that one wireless communication unit of the first wireless communication unit or the second wireless communication unit is operated in a prioritized manner over another wireless communication unit.
