Sliding Display Camera Privacy Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Integrated cameras in portable information handling systems pose a security risk due to potential unauthorized access, with existing manual cover solutions being inconvenient and unreliable.
Innovation Solution
A system where a display in the information handling system housing automatically slides to cover or expose the camera based on the execution or closure of video conferencing applications, using an actuator to manage camera access and maintain security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual cover is used to block the camera lens, then camera security is improved, but device complexity and user convenience deteriorate
Solution Approach 1:
The system automatically detects when camera access is needed and slides the display to expose or cover the camera without user intervention. The processor monitors application states and autonomously controls the display position, eliminating the need for manual cover operations while maintaining security
Solution Approach 2:
The display transitions from a static component to a dynamic one that can slide between covering and exposing the camera based on real-time operational needs. This dynamic adjustment allows the same component (display) to serve both as a security mechanism and a functional display surface
2Ease of manufacture
If the display is extended to the housing bezel to maximize footprint efficiency, then manufacturing efficiency is improved, but camera security deteriorates
Solution Approach 1:
The display is designed to slide relative to the housing, transforming from a fixed component to a movable one. This allows the display to extend to the bezel for manufacturing efficiency while dynamically positioning itself to cover the camera when security is needed, resolving the conflict between footprint optimization and security
Solution Approach 2:
The sliding display serves multiple functions: it acts as both the visual display surface and a security cover for the camera. This multi-functionality eliminates the need for separate security components, allowing the display to extend to the bezel while maintaining camera protection capabilities
3Ease of operation
If the camera is continuously exposed for video conferencing functionality, then ease of operation is improved, but security risk worsens
Solution Approach 1:
The system proactively slides the display to cover the camera before unauthorized access can occur, based on detecting when camera functionality is not needed. This preliminary protective action prevents potential security incidents rather than reacting to them after they occur
Solution Approach 2:
The processor continuously monitors system state and application usage to determine when camera exposure is appropriate. This feedback mechanism ensures the camera is only exposed when genuinely needed for authorized purposes, automatically adjusting display position based on real-time operational context

AI summary
A portable information handling system selectively slides a display integrated in a housing relative to the housing to expose and cover a camera integrated in the housing behind the display. For example, upon execution of a videoconferencing application, an actuator slides the display to expose the camera to support a videoconference, and after the videoconference application completes, the display slides to cover the camera, thus providing security against unauthorized viewing through the camera, which is physically blocked from receiving light.
