Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses connected via wireless LAN struggle to provide users with detailed information about their communication environment, making it difficult to identify and address issues such as communication failures or speed reductions.
Innovation Solution
An image processing apparatus and method that includes a connection processing portion, detection processing portion, transmission/reception processing portion, and output processing portion to detect radio wave strength, transmit/receive data, and output communication environment information, including data amount, radio wave strength, and communication status, allowing users to make informed decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless LAN connection is used for image forming apparatus, then ease of connection is improved, but reliability of communication is worsened due to difficulty in identifying connection causes and communication interference
Solution Approach 1:
The system implements feedback by detecting communication environment parameters (radio wave strength, data transfer amounts, communication status) and providing this information back to users through the operation panel. This enables users to understand the cause of communication issues and take appropriate measures, thereby improving reliability while maintaining wireless connection convenience.
2Device complexity
If only threshold-based notification is provided, then device complexity is reduced, but loss of information about communication environment is worsened
Solution Approach 1:
The notification system is segmented into multiple independent detection functions: radio wave strength detection, data transfer amount detection, and communication status detection. Each function operates independently and provides specific information, allowing the system to maintain low complexity while avoiding information loss through comprehensive multi-parameter monitoring.
3Reliability
If detailed communication environment information is collected and presented, then reliability of communication is improved through better diagnosis, but device complexity is worsened
Solution Approach 1:
The control unit serves multiple functions: it controls the wireless communication unit, detects communication environment parameters, processes detection results, and outputs notifications. By making the control unit universal and multi-functional, the system avoids adding separate dedicated components for each function, thereby improving reliability through comprehensive monitoring while minimizing the increase in device complexity.

AI summary
A connection processing portion (111) performs wireless connection to a predetermined access point (AP). A detection processing portion (112) detects the radio wave strength of the access point (AP). A transmission/reception processing portion (113) transmits and receives image data to and from a device connected to the access point (AP). An output processing portion (115) outputs communication environment information including the radio wave strength of the access point (AP) at the time of transmission and reception of the image data.
