Camera Lens Shutter Mechanism With Position Sensing for Privacy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with camera lenses are at risk of accidental exposure or unauthorized use, compromising user privacy, as existing solutions fail to effectively manage lens operation.
Innovation Solution
A switching mechanism comprising a movable portion, a fixed portion, and a driving assembly, along with a sensing assembly that includes a first and second reference object and sensing member, allows for controlled exposure of the camera lens, enabling it to be blocked or exposed based on user need.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera lens is always exposed for convenient access, then ease of operation is improved, but privacy security deteriorates due to accidental or unauthorized exposure
Solution Approach 1:
The shutter assembly is designed as a movable component that can dynamically transition between covering and exposing the camera lens based on operational needs. The movable portion moves relative to the fixed portion to control light access to the lens, enabling the system to adapt between privacy protection and camera operation states
Solution Approach 2:
The shutter assembly acts as an intermediary component between the external environment and the camera lens. It mediates by selectively blocking or allowing light to reach the lens, thus controlling when the camera can operate while maintaining privacy protection when not in use
2Object-affected harmful factors
If a shutter mechanism is added to block the lens when not in use, then privacy security is improved, but device complexity increases
Solution Approach 1:
The shutter assembly is segmented into distinct components: a fixed portion attached to the device housing and a movable portion that can independently transition between positions. This segmentation allows the shutter mechanism to be integrated into existing device structures without requiring complete redesign of the camera system
Solution Approach 2:
The shutter assembly serves multiple functions: it acts as a physical barrier for privacy protection, a mechanical switch for camera operation control, and potentially an indicator of camera status. This multi-functionality reduces the need for separate components and justifies the added complexity by delivering multiple benefits from a single mechanism
3Object-affected harmful factors
If the movable portion completely blocks the lens, then privacy protection is improved, but light transmission when needed is reduced
Solution Approach 1:
The movable portion is designed to dynamically position itself either covering or exposing the camera lens opening based on operational requirements. When the camera is not in use, the movable portion covers the opening to block light and protect privacy; when the camera needs to operate, the movable portion moves to expose the opening, allowing full light transmission without compromising either privacy protection or light transmission efficiency

AI summary
A switching mechanism is provided. The switching mechanism includes a movable portion, a fixed portion, and a driving assembly. The movable portion is movable relative to the fixed portion. The driving assembly is configured to drive the movable portion to move. The switching mechanism can further include a sensing assembly configured to detect the condition of the movable portion. The sensing assembly includes a first reference object and a first sensing member. The first sensing member corresponds to the first reference object, and the first reference object is adjacent to the first sensing member when the movable portion is in a first condition.
