Multifeed Detection Display for Image Scanning Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image displaying apparatuses require operators to perform complex settings and operations to disable multifeed detection, making it difficult to identify and address multifeed errors, especially when papers with attachments like photos or sticky notes are detected.
Innovation Solution
An image displaying apparatus connected to an image reading device with a multifeed detecting mechanism, which includes a control unit to display read images and highlight multifeed detected portions, allowing operators to set and preview detection ranges and lengths, facilitating easier identification and correction of multifeed errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multifeed detection is disabled through panel settings or PC screen settings, then false detection of papers with attachments can be avoided, but the operator has to perform complicated and troublesome setting operations
Solution Approach 1:
The system automatically determines whether to disable multifeed detection based on image analysis without requiring manual operator configuration. The control unit analyzes the image data to detect attachments and automatically adjusts detection parameters, making the system self-configuring and eliminating complex setting operations while maintaining reliable detection.
Solution Approach 2:
The system dynamically changes detection parameters based on analyzed image characteristics. When attachments are detected, the control unit modifies detection thresholds and parameters automatically, allowing the system to adapt to different paper conditions without manual intervention and maintaining high detection accuracy.
2Loss of information
If only images are displayed on the screen for multifeed detection, then the operator can see the detected content, but it is difficult to identify the cause of multifeed error
Solution Approach 1:
The system segments the displayed information into distinct components: the original image and overlay indicators showing detected multifeed positions. This segmentation allows operators to clearly distinguish between normal content and detection anomalies, making error causes easily identifiable while preserving complete detection information.
Solution Approach 2:
The system uses color-coded overlay indicators on the displayed images to highlight multifeed detected portions. Different colors indicate different detection states or confidence levels, enabling operators to quickly identify error causes by visual differentiation without losing any detection information.
