Blade Open-Close Device with Light Emitter for Privacy Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera shutter mechanisms in small electronic devices are difficult to determine as open or closed from the outside and do not effectively enhance user comfort for privacy protection, as they may not fit in smaller spaces and lack visibility of their state.
Innovation Solution
A blade open-close device with a light emitter that moves between a base and a cover, allowing the open or closed state to be visible from outside, using an actuator to control the blade's position and communicate the state through light emission, ensuring the camera cannot capture images unintentionally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera shutter is used to cover and uncover the lens aperture, then privacy protection is improved, but the device size increases and space requirements exceed those of smaller electronic devices
Solution Approach 1:
The blade is divided into multiple segments that can move independently, allowing the shutter mechanism to be more compact while maintaining its privacy protection function. The segmented blade fits within smaller device constraints while still effectively covering the lens aperture when closed.
Solution Approach 2:
The blade structure is designed to nest within the device housing when in the closed position, with the blade chamber integrated into the existing device architecture. This nesting approach minimizes the volume occupied by the shutter mechanism while preserving its privacy protection capability.
2Volume of moving object
If the blade is made smaller to fit in smaller electronic devices, then device size is reduced, but the visibility of the blade's open or closed state deteriorates
Solution Approach 1:
The blade incorporates a light emitter that changes its illumination state to indicate whether the blade is open or closed. When the blade is closed, the light emitter emits light in a specific pattern or intensity, providing clear visual feedback to users about the privacy protection state, thereby solving the visibility issue despite the blade's small size.
Solution Approach 2:
A light emitter is introduced as an intermediary element between the blade and the user's perception. This mediator provides visual information about the blade's state without requiring the blade itself to be large or visible, thus resolving the contradiction between compact size and state visibility.
3Volume of moving object
If the blade is made smaller for compact devices, then device size is reduced, but user comfort regarding privacy protection deteriorates
Solution Approach 1:
The light emitter provides clear visual feedback about the blade's state, enabling users to easily determine whether privacy protection is active. This enhances user comfort and confidence in the privacy protection function, even though the physical blade is small and not directly visible to users.
Solution Approach 2:
The light emitter serves as a feedback mechanism that communicates the blade's state to users in real-time. This feedback loop allows users to verify that privacy protection is functioning as intended, thereby maintaining high user comfort despite the reduced size of the physical blade.

AI summary
A blade open-close device includes a blade for which an open or closed state is easily viewable from outside. A blade open-close device includes a base having a base opening, and a cover covering the base and having a cover opening adjacent to the base opening in the base in Z-direction. The blade open-close device further includes a blade movable in X-direction in a blade chamber between the base and the cover and including a light emitter that emits light, and an actuator that moves the blade to a closing position to expose at least part of the light emitter in the blade through the cover opening and retracts the blade to an opening position to allow the cover opening and the base opening to communicate with each other.
