Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image acquiring devices for business cards are inconvenient due to the need for manual positioning and insertion, which is time-consuming and hinders portability.
Innovation Solution
An image acquiring device with a positioning assisting unit that emits light to form positioning marks on a planar surface, allowing for quick and precise alignment of the object to be captured, integrated into a notebook computer or other electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a base is used to position the business card in the conventional device, then image acquisition is facilitated, but portability and ease of operation deteriorate due to the need for manual insertion and positioning
Solution Approach 1:
The positioning assisting unit automatically projects positioning marks onto the planar surface without requiring manual intervention. The system self-guides the positioning process by illuminating the target area and detecting the position of the business card relative to the projected marks, eliminating the need for users to manually insert and position cards in a base.
Solution Approach 2:
The patent replaces the mechanical base structure with an optical positioning system. Instead of using a physical base with slots or guides to hold the business card, the system uses projected light marks and image acquisition to determine position, substituting mechanical constraint with optical guidance.
2Productivity
If manual insertion and positioning of business cards is required, then device structure can be simple, but time consumption increases significantly
Solution Approach 1:
The positioning assisting unit projects positioning marks onto the planar surface before the user needs to capture the business card image. These pre-projected marks serve as visual guides that enable rapid alignment, eliminating the time-consuming process of manual positioning and insertion required in conventional systems.
3Adaptability or versatility
If a base is used for positioning, then image acquisition is enabled, but portability deteriorates
Solution Approach 1:
The patent extracts the positioning function from the base structure and implements it as a separate positioning assisting unit that can operate independently. This allows the system to function without requiring a dedicated base, making it portable while maintaining ease of operation through automated positioning marks.
