Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in aligning documents correctly on imaging systems, leading to suboptimal scan quality and increased time due to inadequate visual cues for positioning, and existing solutions are either complex or costly.
Innovation Solution
A system that includes an imaging unit with an image sensing member and image processing member to capture and convert images into a digital format, coupled with a display unit showing a placement-guiding display object to facilitate correct alignment and orientation of documents on the imaging surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual indicators (moldings, painted arrows, markings) are provided on the housing to guide document alignment, then users can be guided about positioning, but the indicators may be overlooked, wear off over time, and add to manufacturing costs
Solution Approach 1:
The patent replaces physical visual indicators (moldings, painted arrows, markings) with a digital display system that shows alignment guidance on a screen. The display unit presents a graphical representation of the imaging surface with visual cues that update in real-time, eliminating the need for permanent physical markings on the housing.
Solution Approach 2:
The patent creates a digital copy or graphical representation of the imaging surface on the display unit. This virtual model includes visual indicators and alignment cues that mirror the actual imaging surface layout, allowing users to see where to place documents without relying on physical markings that may wear off.
2Illumination intensity
If the scanner lid is opened to a substantial angle to make indicators visible, then users can see the alignment marks, but users may fail to align documents correctly and need to reproduce scans again
Solution Approach 1:
The patent introduces a display unit as an intermediary between the user and the imaging surface. The display shows a graphical representation with alignment cues that are always visible and update in real-time, serving as a reliable mediator that guides document placement without requiring the scanner lid to be opened at specific angles.
Solution Approach 2:
The display unit provides real-time feedback to users about document alignment status. As users position documents on the imaging surface, the display updates to show whether the document is correctly aligned, allowing users to adjust placement immediately rather than discovering misalignment after scanning.
3Adaptability or versatility
If smart scanning mode scans the entire platen area to discern photos from background, then photos can be scanned from any position, but the operation is complex and takes more time than placing photos at a known position
Solution Approach 1:
The patent performs preliminary action by displaying alignment guidance and detecting document presence before the actual scanning occurs. The system shows users where to place documents and detects when documents are properly positioned, allowing users to quickly place photos at optimal positions without needing the system to scan the entire platen to find them.
Solution Approach 2:
The patent makes the alignment guidance system dynamic by updating the display in real-time based on scanner position and document detection. The visual indicators on the display move and change to reflect the current scanner state, providing users with dynamic feedback that helps them quickly position documents rather than requiring static pre-programmed positions.
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
The system effectively guides users to align documents optimally, improving scan quality and reducing the need for costly visual indicators, thus enhancing user experience and reducing operational inefficiencies.
