Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses face challenges in efficiently managing communication over multiple frequency bands, particularly in adjusting the number of connected devices and maintaining stable connections due to differences in communication quality and speed between the 2.4 GHz and 5 GHz bands.
Innovation Solution
The apparatus includes communication means capable of switching frequency bands based on predetermined conditions, such as the receipt of a print job, to optimize the number of connected devices and maintain stable connections by switching from the 5 GHz band to the 2.4 GHz band, thereby increasing the availability of higher-speed and more stable communication channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image forming apparatus communicates over the 5 GHz band to achieve higher communication speed and stability, then communication quality improves, but the number of simultaneous connections is limited
Solution Approach 1:
The apparatus segments the communication load by frequency band, dedicating the 5 GHz band for high-quality connections and the 2.4 GHz band for additional connections, thereby resolving the conflict between connection quality and connection capacity
Solution Approach 2:
The system dynamically switches between frequency bands based on communication conditions, allowing flexible allocation of communication resources to balance connection quality and number of simultaneous connections
2Adaptability or versatility
If the image forming apparatus switches frequency bands to adjust the number of connected devices, then connection capacity increases, but communication stability may deteriorate
Solution Approach 1:
The control unit acts as an intermediary that monitors communication conditions and automatically switches frequency bands, allowing the system to expand connection capacity while maintaining stability through intelligent management
Solution Approach 2:
The system changes the frequency band parameter based on communication conditions, switching between 5 GHz and 2.4 GHz bands to balance connection capacity and communication stability
3Speed
If the apparatus prioritizes 5 GHz band communication for high speed, then communication speed improves, but availability of channels decreases when the band is full
Solution Approach 1:
The system adds another dimension (2.4 GHz frequency band) to the communication architecture, providing an additional channel dimension when the primary 5 GHz band reaches capacity, thus maintaining both speed and availability
