Scanner Control Unit for Communication Test Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face communication errors when attempting to store scanned data using the scan-to-folder function due to incorrect folder registration or login information in scanners, leading to failed data storage and hindered workflow.
Innovation Solution
An image reading device with a control unit that executes a communication test to determine successful connection with the storage destination, featuring both manual and automatic test modes. The manual mode initiates tests upon user instruction, while the automatic mode starts tests based on user-set conditions, such as storage destination registration, selection, or power-saving states, to prevent communication errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the scanner automatically executes the scan-to-folder function without communication testing, then the workflow efficiency is improved, but communication errors occur due to incorrect folder registration or outdated login information
Solution Approach 1:
The communication test is executed in advance before the scan-to-folder function is performed. The control unit automatically tests communication with the storage destination at predetermined timings (when storage destination information is registered, when it is selected, or when the scanner wakes from sleep mode) to ensure connectivity before actual data transmission, thereby preventing communication errors without hindering workflow efficiency
2Reliability
If the user manually checks communication status before each scan-to-folder operation, then communication reliability is improved, but the user burden and operation time increase
Solution Approach 1:
The scanner performs self-diagnosis by automatically executing communication tests at predetermined timings without requiring user intervention. The control unit monitors communication status proactively and notifies the user only when an abnormality is detected, transforming the system from passive user-checking to active self-monitoring, thereby maintaining reliability while reducing user burden
3Reliability
If the scanner executes communication tests at all possible timings, then communication reliability is improved, but the device complexity and processing overhead increase
Solution Approach 1:
The control unit is configured to execute communication tests only at predetermined timings that are critical for ensuring communication reliability: when storage destination information is registered, when it is selected, or when the scanner wakes from sleep mode. This selective timing approach ensures that tests are performed at moments when communication status is most likely to change, maintaining high reliability without requiring continuous or excessive testing that would increase device complexity
Solution Approach 2:
Different communication test strategies are applied at different operational stages. The control unit adjusts the testing frequency and depth based on the specific context (registration phase, selection phase, or sleep wake-up phase), ensuring appropriate verification without uniform over-testing, thereby optimizing the balance between reliability and complexity
