UMPC Pivoting Arm Stabilizes Recording Media for Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultra mobile personal computers (UMPCs) face challenges in precisely capturing images of recording media due to user-hand instability, resulting in poor image quality when copying items like business cards.
Innovation Solution
An electronic device with a pivoting arm and cover mechanism that stabilizes the recording medium in front of a high-resolution image capturing element, allowing for precise image capture by pivoting the arm between positions and activating the element when a recording medium is inserted, and includes a position detector to automate the image capturing process.

Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of UMPC distance and orientation is used, then the device structure remains simple, but image capture precision deteriorates due to hand instability
Solution Approach 1:
The patent implements a pivoting arm mechanism that allows dynamic adjustment of the UMPC's position and orientation relative to the recording medium. The arm can rotate between multiple positions, enabling the device to adapt to different capture scenarios while maintaining stable positioning through mechanical support rather than manual holding.
Solution Approach 2:
The pivoting arm serves as an intermediary mechanical structure between the user and the UMPC device. Instead of directly holding the device, the user operates the arm mechanism, which then stabilizes and positions the UMPC precisely. This intermediary structure filters out hand instability while preserving user control capability.
2Productivity
If manual adjustment is used, then the device operation remains simple, but productivity deteriorates due to inconvenient image copying process
Solution Approach 1:
The system performs preliminary positioning actions through the pivoting arm mechanism, pre-establishing the optimal capture position and orientation before the actual imaging process begins. This preliminary mechanical positioning eliminates the need for continuous manual adjustments during the capture process, thereby improving efficiency without significantly complicating operation.
Solution Approach 2:
The UMPC device, when mounted on the pivoting arm, essentially positions and orients itself relative to the recording medium through the mechanical support system. Once the arm is positioned, the device maintains stable capture conditions automatically, reducing the need for continuous user intervention and improving overall copying efficiency.
3Reliability
If manual positioning is used, then the device structure remains simple, but reliability deteriorates due to unstable hand control
Solution Approach 1:
The pivoting arm provides dynamic mechanical support that adapts to different positioning needs while maintaining stability during the capture process. The ability to pivot between fixed positions allows the system to achieve reliable positioning without requiring complex active stabilization systems, balancing mechanical complexity with position stability.

AI summary
An electronic device comprises a body, a first image capturing element, a cover and a arm. The body comprises a first surface and a second surface, with the first surface opposite to the second surface. The first image capturing element is disposed on the first surface. The cover is connected to the body, movable between a first cover position and a second cover position, wherein the cover covers the first image capturing element when the cover is in the first cover position, and the first image capturing element is actuated when the cover is in the second cover position. The arm is connected to the cover, pivoting between a first position and a second position, wherein when the arm is in the second position, a recording medium is received on a first end of the arm, and the first image capturing element captures an image data therefrom.
