Solution Overview

Problem

Users of computing devices with cameras face concerns about privacy, as cameras can be accessed and controlled without the user's knowledge, potentially allowing unauthorized image capture.

Innovation Solution

A privacy solution that allows users to intuitively control a shutter to cover the image sensor of a camera using natural gestures, such as taps and swipes, which are integrated directly into the camera, providing electrical isolation from the rest of the computing device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the camera is mounted on an exterior portion of the computing device to promote capture of electronic images, then the ease of operation is improved, but the privacy security deteriorates as the camera may be visible and accessible to the user at all times

Engineering Contradiction:
Improvecamera accessibilityVSAvoidprivacy security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The camera system is segmented into functionally independent parts: the image capture device remains integrated in the computing device, while the shutter mechanism is physically separated and mounted directly on the camera housing. This segmentation allows the shutter to be controlled independently through touch gestures on the camera itself, without requiring communication with or control from the computing device's operating system, thereby enhancing privacy security while maintaining ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The camera is equipped with self-service capabilities through touch-sensitive functionality integrated directly into the camera housing. Users can perform gestures such as tapping or sliding on the camera surface to control the shutter, allowing the camera to serve its own privacy control needs without external intervention from the computing device. This self-service approach ensures that even if the computing device is compromised, the camera maintains independent privacy protection.

Inventive Principle:
Principle #25Self-service

2Reliability

If a shutter mechanism is added to cover the image sensor, then the privacy security is improved, but the device complexity increases

Engineering Contradiction:
Improveprivacy securityVSAvoidcamera structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The shutter mechanism is merged with the camera housing structure, eliminating the need for separate control electronics, processors, or communication interfaces that would typically be required for privacy control. The touch-sensitive surface is integrated directly into the camera housing, and the shutter is mechanically coupled to the same structure, creating a unified component assembly that adds privacy functionality without proportionally increasing overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces complex electronic control systems with a simplified mechanical touch-based control mechanism. Instead of requiring software drivers, operating system integration, or electronic sensors, the system uses direct mechanical touch gestures on the camera housing to trigger shutter activation. This mechanical substitution dramatically reduces the complexity additions while maintaining effective privacy control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If the shutter control is electrically isolated from the computing device, then the privacy security is improved, but the ease of operation deteriorates as users must learn new gesture controls

Engineering Contradiction:
Improveprivacy securityVSAvoidcontrol intuitiveness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The camera provides self-service control through intuitive touch gestures performed directly on the camera housing. Users naturally tap, slide, or gesture on the camera surface to control the shutter, making the interaction as intuitive as touching any other object. This self-service approach eliminates the need to learn complex command structures or navigate software menus, maintaining ease of operation despite electrical isolation from the computing device.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The touch-sensitive surface of the camera housing serves as an intermediary between the user and the shutter mechanism. This intermediary layer translates natural human touch gestures into shutter control commands, bridging the gap between user intent and mechanical action. The intermediary enables intuitive control without requiring direct electrical connection to the computing device, as the camera housing itself mediates the control input.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Examples disclosed herein provide an image capture device. As an example, the image capture device includes an image sensor, a shutter, and a touch-enabled layer disposed above the image sensor. A controller of the image capture device is to register a user touch interaction with the touch-enabled layer and, based on a gesture detected from the user touch interaction, cycle between engaging the shutter to cover the image sensor and disengaging the shutter to expose the image sensor.
