Movable Camera Cover with Manual Reset for Privacy Assurance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home surveillance systems lack assurance for users that cameras are not activated unless a legitimate need arises, as existing solutions do not provide a reliable mechanism to prevent unauthorized imaging and ensure user control over camera activation and deactivation.
Innovation Solution
A monitoring unit with a movable camera cover that automatically opens in response to an alarm triggering event but can only be manually closed, featuring a releasable latching mechanism and visual indicators to ensure user awareness of camera activation status, preventing remote closure and maintaining privacy until a legitimate imaging need is met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera is equipped with a movable cover that can be opened remotely to allow imaging, then the camera can be activated for surveillance purposes, but users cannot be assured that the camera is not activated when it should remain private
Solution Approach 1:
The patent inverts the traditional remote control mechanism by allowing remote opening of the cover but preventing remote closing. The cover can only be closed manually by physical intervention at the camera location, creating an asymmetric control mechanism that provides visual assurance to users that the camera cannot be activated without their knowledge.
Solution Approach 2:
The mechanical cover serves as an intermediary physical barrier between the camera lens and the external environment. This tangible intermediate element provides visual confirmation of camera status and prevents unauthorized imaging by requiring physical manipulation to close, thereby mediating between remote activation capabilities and user privacy assurance.
2Adaptability or versatility
If a cover is made movable to allow remote camera activation, then surveillance functionality is enabled, but the mechanism becomes complex requiring remote control systems
Solution Approach 1:
The patent segments the cover control function into two distinct modes: remote electronic control for opening the cover to enable surveillance, and manual physical control for closing the cover to ensure privacy. This segmentation simplifies the overall mechanism by using different control methods for different operational states, avoiding the need for a complex bidirectional remote control system.
3Ease of operation
If the cover can be closed remotely to maintain privacy, then user control is enhanced, but users cannot visually confirm that the camera has been deactivated
Solution Approach 1:
The patent inverts the traditional remote control mechanism by allowing remote opening of the cover but preventing remote closing. The cover can only be closed manually by physical intervention at the camera location, creating an asymmetric control mechanism that provides visual assurance to users that the camera cannot be activated without their knowledge.

AI summary
A monitoring unit (101) for a surveillance system, comprising a camera and a cover (115), the cover being movable in response to a camera activation signal, from a first position obscuring a lens (103) of the camera and preventing the camera from imaging a zone of interest to a second position not obscuring the camera lens, the monitoring unit being further arranged such that the cover is movable from the second position to the first position only through manual intervention of a person. Disclosed is also a surveillance system comprising such a monitoring unit.
