Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Internet-enabled video devices are vulnerable to unauthorized access, leading to security breaches that can compromise individual privacy, and there is a need for easy access and control of security features using common computing devices over a network connection.
Innovation Solution
An Internet-connected video device with a privacy module that can automatically or manually obscure the field of view using a polymer-dispersed liquid crystal (PDLC) module, accompanied by a visual indicator to alert individuals and a wireless transceiver for network connectivity, allowing remote activation and control via smartphones or computers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera remains constantly active for monitoring, then security monitoring capability is improved, but privacy of individuals is compromised
Solution Approach 1:
The privacy module dynamically changes the camera lens between transparent and opaque states based on operational conditions. When privacy protection is needed, the lens becomes opaque to block the view; when monitoring is required, it becomes transparent. This dynamic adaptation allows the system to switch between security monitoring and privacy protection modes.
Solution Approach 2:
The privacy module utilizes optical property changes (transparency to opacity transition) to control visibility. This change in optical state allows the camera to either capture images/video or prevent viewing, effectively managing the balance between monitoring capability and privacy protection.
2Object-affected harmful factors
If the privacy module is activated to obscure the field of view, then privacy protection is improved, but security monitoring capability deteriorates
Solution Approach 1:
The system dynamically switches the privacy module state based on detected conditions. When unauthorized access or potential threats are detected, the privacy module activates to obscure the view. When no threats are present, it remains inactive to allow normal monitoring, thus maintaining security capability when safe.
Solution Approach 2:
The privacy module serves as a preliminary protective measure that activates in response to detected threats or unauthorized access attempts. By obscuring the view before complete compromise occurs, it prevents potential privacy breaches while maintaining monitoring capability during normal operation.
3Loss of time
If automatic privacy breach detection is implemented, then response time to security threats is improved, but device complexity increases
Solution Approach 1:
The system implements automatic detection of privacy breaches through sensors or monitoring mechanisms that detect unauthorized presence or access attempts. When a breach is detected, the system provides feedback by automatically activating the privacy module to obscure the view, creating a closed-loop security response system.
Solution Approach 2:
The privacy module system operates autonomously by automatically detecting potential privacy breaches and activating protection measures without requiring manual intervention. The detection and response mechanisms work self-service to maintain security while reducing the need for constant human monitoring.
4Ease of operation
If remote access control is enabled for security features, then ease of operation is improved, but vulnerability to unauthorized access increases
Solution Approach 1:
The system uses a remote device as an intermediary for controlling the privacy module. Users can activate or deactivate the privacy protection feature remotely through connected devices such as smartphones or computers, allowing convenient control while maintaining security through authenticated access to the remote interface.

AI summary
Systems and methods for secure video devices are provided. A video device includes a privacy module that can be automatically or manually activated to obscure the field of view of the video device. The video device also includes a visual indicator for indicating when the camera has been activated, in order to alert individuals within view of the camera that the camera is active. The system can automatically detect when a privacy breach occurs (e.g., if an unauthorized user gains access to the camera) and can automatically activate the privacy module in response to the detected privacy breach in order to obscure the field of view of the camera and maintain the privacy of individuals within the field of view of the camera.
