Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image reader systems require complex operations for wireless setup, involving separate devices for reading connection setup information and limited displayable information, which complicates user understanding and operability.
Innovation Solution
An image reader system with a scanning unit, control unit, and wireless communication unit that executes optical information recognition processing to read wireless setup information from an original document, allowing for automatic acquisition and display of necessary connection details, such as SSID and encryption key, without requiring manual entry of character strings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connection setup information is read using a camera or code reader, then wireless setup can be performed, but a separate device is required and the operation becomes complex
Solution Approach 1:
The patent combines the code reading function and wireless setup function into a single image reader device. The control unit is configured to read connection setup information in the form of a code, store it, and perform wireless setup using this information, eliminating the need for separate camera or code reader devices.
Solution Approach 2:
The image reader is designed to perform multiple functions: it can read various types of codes (barcodes, two-dimensional codes), store the connection setup information, and execute wireless LAN setup. This multi-functional approach replaces the need for multiple specialized devices.
2Ease of operation
If a small display is used for input operations, then the device remains compact, but the amount of displayable information is limited and operability improvement is limited
Solution Approach 1:
The system automatically reads the code containing connection setup information and performs wireless setup without requiring the user to manually input characters. The control unit extracts necessary information from the code, stores it, and uses it for wireless connection, making the process self-service and eliminating the need for extensive display input capabilities.
3Reliability
If manual character string entry is required for wireless setup, then connection information can be input accurately, but the operation becomes complex and time-consuming
Solution Approach 1:
The connection setup information is pre-encoded in a code format that can be automatically read. The control unit reads this code, stores the connection setup information, and prepares for wireless setup in advance, eliminating the need for time-consuming manual character entry during the actual setup process.
Solution Approach 2:
The patent replaces the mechanical process of manual keyboard input with an optical reading system. The control unit uses optical recognition to read the code and automatically extract connection information, substituting the manual typing mechanism with an automated optical reading and data extraction process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies the wireless setup process by allowing users to easily read and recognize wireless setup information through optical recognition, improving operability and reducing the complexity of the setup procedure.
Implementation Method 1
a scanning unit configured to read an original document provided with an image and convert the image into image data
Implementation Method 2
The control unit is configured to execute optical information recognition processing on the image data, and acquires wireless setup information for connection to the wireless LAN master device based on the character information acquired
Data Source
AI summary
A control unit of an image reader executes OCR (optical character recognition processing) on image data as a result of scanning a setup guide, and upon acquiring an SSID and an encryption key, attempts to communicate with a corresponding wireless LAN master device using the SSID and the corresponding encryption key.
