Hands-Free POV Video Camera with Horizon and Laser Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing first-person video cameras for action sports are not hands-free and require tethering to a separate digital video recorder or camcorder, limiting their usability in action sports.
Innovation Solution
A portable digital video camera with an integrated hands-free, POV action sports design, featuring a camera housing, lens, image sensor, manual horizon adjustment control, laser alignment system, microphone, and a "quick-release" mounting system for adjusting image capture orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tethered lens approach is used to capture first-person video, then the camera can be integrated with a separate digital video recorder, but the system loses hands-free capability and requires additional tethering equipment
Solution Approach 1:
The patent merges the camera and digital video recorder into a single integrated unit. The camera housing contains both the image sensor and the digital video recorder, eliminating the need for separate tethered devices. This integration directly resolves the contradiction by providing hands-free operation without requiring additional tethering equipment, as the combined device functions as a self-contained system.
2Ease of operation
If conventional tethered cameras are used, then the lens can be separated from the recorder, but the system requires complex mounting techniques to achieve hands-free operation
Solution Approach 1:
The patent extracts the camera functionality from the tethered lens approach and integrates it directly into the recorder housing. By taking out the camera from the separate tethered configuration and embedding it within the recorder, the system eliminates complex mounting techniques while achieving hands-free operation. The camera is positioned within the recorder housing with direct optical access, removing the need for external mounting arrangements.
3Ease of operation
If an integrated hands-free POV camera is designed, then hands-free operation is achieved, but the image orientation may not be properly aligned with the housing plane
Solution Approach 1:
The patent introduces a manually adjustable mechanism that allows dynamic repositioning of the image sensor relative to the housing plane. This adjustment mechanism enables the image orientation to be deliberately aligned with the desired capture direction, resolving the contradiction between hands-free operation and manufacturing precision. The adjustable design allows post-manufacturing calibration to achieve proper orientation alignment.
4Adaptability or versatility
If the camera is mounted in a fixed position, then the structure is simple, but the image capture orientation cannot be adjusted for different applications
Solution Approach 1:
The patent incorporates a manually adjustable mounting system that allows the camera housing to be repositioned relative to the mounting surface. This dynamic adjustment capability enables adaptation to different capture orientations and applications while maintaining a relatively simple overall structure. The adjustment mechanism provides versatility without requiring complex automated positioning systems.

AI summary
An integrated hands-free, point of view, action-sports, digital video camera (or camcorder) (10) includes: a rotary horizon adjustment controller (14) for adjusting the orientation of a horizontal image plane (16) recorded by an image sensor with respect to the orientation of a camera housing (22); a laser alignment system with laser sources (48) capable of projecting light to define a horizontal projection axis (52) that is coordinated with orientation of the horizontal image plane (16); a manually operable switch (80), which covers a microphone (90) whenever the switch (80) is in the OFF position, for controlling video data capture; and a “quick-release” mounting system (120) that retains a desired orientation of the camera (10).
