Moveable Mirror Assembly for Covert Video Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable electronic devices face discomfort and conspicuousness when trying to capture images or videos, as they need to hold the device vertically, which can be awkward and draw attention.
Innovation Solution
A case with a built-in light-redirecting component, such as a mirror or prism, allows the device to be held in a more natural position while capturing images or videos, redirecting light to the camera and enabling covert recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the device is held vertically in front of the user to capture images or videos, then the camera can capture the desired view, but the user experiences discomfort and draws attention
Solution Approach 1:
The patent introduces a mirror assembly that redirects light from a horizontal field of view to the vertically-oriented camera sensor. This dimensional transformation allows the camera to capture images as if it were facing forward while the device remains held vertically, enabling covert recording without the user needing to hold the device in an awkward horizontal position that would draw attention.
Solution Approach 2:
The mirror assembly acts as an intermediary optical element between the external scene and the camera sensor. By placing the mirror at a 45-degree angle within the case, it intercepts light traveling horizontally and redirects it vertically to the camera, serving as a mediator that enables the camera to see in a direction perpendicular to its physical orientation.
2Object-affected harmful factors
If the device is held vertically for covert recording, then inconspicuousness is achieved, but the user cannot easily manipulate controls
Solution Approach 1:
The mirror assembly enables the camera to capture horizontal field of view while the device is held vertically, allowing the user to maintain a natural vertical holding position that keeps controls accessible while achieving covert recording through the optical redirection mechanism.
3Ease of manufacture
If a fixed mirror is used in the case, then light redirection works for one orientation, but the device cannot be used in different orientations
Solution Approach 1:
The mirror assembly is designed to be movable rather than fixed, allowing it to be adjusted to different angular positions. This dynamic configuration enables the mirror to redirect light appropriately whether the device is held in portrait or landscape orientation, providing versatility while maintaining a relatively simple mounting structure that allows for adjustment.
