Sliding Security Door for Camera Lens Aperture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic communication devices lack a physical security mechanism to prevent unauthorized access and recording by their integrated cameras, which can be remotely activated, causing user anxiety and potential data breaches.
Innovation Solution
A slideable security door made of flexible plastic with grasping means and mating structures, designed to cover and uncover the camera lens aperture independently of the camera's functioning, allowing manual or automatic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a physical lens cover is added to protect the camera lens, then the lens is protected from damage, but the device complexity increases and the lens cover may obstruct the camera when not properly managed
Solution Approach 1:
The patent extracts the security function from the camera lens protection function. Instead of using a traditional lens cover that serves both purposes, the invention introduces a separate security door mechanism that specifically addresses security concerns without interfering with lens protection. The lens remains protected by the device design while the security door independently controls access to the camera aperture.
Solution Approach 2:
The patent segments the camera protection system into two independent components: the lens protection mechanism (existing in device design) and the security door mechanism (new addition). This segmentation allows each component to perform its specific function without compromising the other, resolving the contradiction between lens protection and device complexity.
2Reliability
If the camera is permanently disabled to prevent spying, then security is improved, but the camera functionality is lost
Solution Approach 1:
The patent applies the dynamics principle by making the security door movable rather than fixed. The door can be opened or closed based on user needs, allowing the camera to be dynamically enabled or disabled. This resolves the contradiction by providing security when the door is closed while maintaining camera functionality when the door is opened, unlike permanent disabling which sacrifices functionality entirely.
Solution Approach 2:
The security door system allows users to control their own security and camera functionality without requiring permanent disabling by the manufacturer. Users can independently manage the door position based on their security needs, embodying the self-service principle where the user controls the balance between security and functionality.
3Reliability
If a security door is added to cover the camera aperture, then unauthorized access is prevented, but the device complexity increases
Solution Approach 1:
The patent employs a thin, flexible security door made of material such as plastic that can slide smoothly within channels. This flexible thin-film approach provides effective security coverage while minimizing the added complexity and bulk compared to rigid mechanical shutters or covers. The flexibility allows for smooth operation and integration within the device's existing structure.
Solution Approach 2:
The patent replaces complex mechanical locking systems with a simpler sliding door mechanism that moves within channels. The door can be positioned in open or closed states without requiring complex actuators or locking mechanisms, thereby providing unauthorized access prevention while keeping the added complexity minimal.
4Shape
If the camera lens is made flush with the device case, then the design is sleek and compact, but the lens becomes vulnerable to scratches and damage
Solution Approach 1:
The patent implements a nested structure where the security door is positioned within channels that are integrated into the device case. The door can slide within these nested channels to cover or uncover the lens aperture. This nesting approach maintains the sleek external design of the device while providing internal protection mechanisms that do not compromise the external aesthetics.

AI summary
A security door (100) for a communication device used to record and store or transmit visual data, the communication device having a lens (40) for an integrated camera positioned in an aperture (28) cut into a shell (24) of the visual communication device, the security door slideably affixed to the shell by a channel (52) affixed to an inner side (26b) of the shell, allowing a user to physically slide the door over the aperture to cover or uncover the lens, as desired, such covering and uncovering of the lens independent of camera function. In another embodiment, software is used to open and close the door. In some embodiments, the security door is disposed as a pocket door slideably moving inside a pocket door frame.
