Camera Lens Sliding Door with Linear Actuator for Privacy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with cameras are vulnerable to hacking, leading to privacy invasion through unauthorized image capture, and existing solutions to hide the camera lens can damage the device's exterior.
Innovation Solution
An electronic device with a door mechanism between the housing and the camera lens, controlled by a driving unit using a linear actuator, allows the lens to be slidably opened or closed based on user authentication and conditions, preventing unauthorized image capture while maintaining the device's exterior integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate attachment or door knob is installed on the exterior to hide the camera lens, then privacy protection is improved, but the exterior appearance is spoiled and gaps may be generated between the main body and display
Solution Approach 1:
The door is nested within the housing structure itself, with the door forming an integral part of the housing rather than being a separate attachment. The door is disposed between the housing and the lens, allowing it to slide within the existing structural boundaries, thus protecting privacy without altering the exterior appearance or creating gaps.
Solution Approach 2:
The door mechanism is merged with the housing structure, where the door is formed as part of the housing assembly. The driving unit is also integrated into the housing, combining multiple functions (structural support, door operation, lens control) into a unified system that maintains exterior integrity while enabling privacy protection.
2Reliability
If a separate structure for hiding the lens is attached on the exterior, then camera protection is improved, but gaps are generated between the main body and display
Solution Approach 1:
The door and driving unit are nested within the housing structure, with the door sliding within the housing boundaries. This nested arrangement protects the camera lens without compromising the structural integrity of the device, as all components are contained within the existing housing framework rather than being external attachments.
Solution Approach 2:
The door mechanism is merged with the housing structure, where the door is formed as part of the housing assembly. This integration ensures that the door and housing move as a unified structure, maintaining structural integrity while enabling camera protection functionality.
3Ease of operation
If the lens is opened or closed by a separate attachment on the exterior, then privacy control is improved, but the exterior is spoiled
Solution Approach 1:
The door mechanism is merged with the housing structure, where the door is formed as part of the housing assembly. This integration ensures that the door and housing move as a unified structure, maintaining structural integrity while enabling camera protection functionality.
4Reliability
If a door is disposed between the housing and lens with slidable movement, then privacy protection is improved, but the device complexity increases
Solution Approach 1:
The complex mechanical door knob mechanism is replaced with a driving unit that can be controlled electronically. The driving unit receives control signals from the processor and automatically actuates the door, replacing manual mechanical operation with an electronically controlled system that is simpler and more reliable.
Solution Approach 2:
The door mechanism operates automatically based on control signals from the processor. When the processor determines that privacy protection is needed, it sends a control signal to the driving unit, which automatically actuates the door without requiring user intervention. This self-service operation reduces complexity by eliminating the need for separate control interfaces.
