Blade Open-Close Device for Camera Module Miniaturization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic devices with camera units face challenges in determining whether image capturing is occurring, especially with smaller devices where the open-close device is obstructive and limited in size, leading to concerns about unintended image capture.
Innovation Solution
An electronic device design featuring a hollow frame with a blade open-close device that covers and uncovers an opening, utilizing an actuator and a base with a cover, allowing users to confirm no image capturing is in progress while minimizing the device's size and enhancing user comfort.

Engineering Contradiction Analysis
1Reliability
If the open-close device includes a base extending across the entire area in its longitudinal direction, then the device provides adequate support and coverage, but the device size increases and miniaturization is obstructed
Solution Approach 1:
The base is segmented into a first base portion and a second base portion that are disposed at different positions in the longitudinal direction. This segmentation allows the base to provide adequate support coverage while reducing the overall longitudinal extent of the base, enabling miniaturization of the open-close device without compromising structural support.
Solution Approach 2:
The cover extends in the longitudinal direction beyond the base, creating a dimensional extension that allows the blade to be supported at multiple points. This dimensional change enables the base to be shorter while still providing adequate support through the extended cover structure.
2Volume of moving object
If the base is made shorter to miniaturize the open-close device, then device size is reduced, but support coverage and structural stability may be compromised
Solution Approach 1:
The base is divided into multiple portions (first and second base portions) positioned at different locations along the longitudinal direction. This segmentation distributes the support function across multiple discrete elements, maintaining structural stability even when the overall base length is reduced for miniaturization.
Solution Approach 2:
The cover acts as an intermediary element that extends beyond the base and provides additional support for the blade. This intermediary structure compensates for the reduced base length, ensuring that the blade remains properly supported and the overall structural stability is maintained despite the smaller base footprint.

AI summary
An electronic device allows the user to notice that no image capturing is being performed and increases the user comfort as well as includes a small open-close device incorporated in a limited space. A camera module is covered by a blade. This allows the user to notice that no image capturing is being performed and increases the user comfort. A base is attached to a first surface of a module board, and a cover has a first end in the longitudinal direction attached to the base and a second end in the longitudinal direction supported by the first surface of the module board. The base may not extend to the second end of the cover in the longitudinal direction and can have a shorter length (miniaturized), further miniaturizing a blade open-close device.
