Point-of-View Camera Harness With Damped Positioning Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stabilization devices for subjective shooting, such as those used in cinematography and medical training, are excessively heavy and require manual camera orientation, limiting the operator's mobility and image quality, especially in delicate operations.
Innovation Solution
A subjective view device with a harness and positionable arm that uses mechanical damping and adjustable rods to stabilize the camera close to the operator's line of sight, allowing hands-free operation and improved image quality by distributing the weight and compensating for movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a stabilization device with counterweight and hydraulic means is used, then image stabilization is improved, but device weight increases excessively
Solution Approach 1:
The patent extracts the heavy counterweight and hydraulic stabilization systems from the device, replacing them with a lightweight mechanical arm supported by elastic elements. The camera is positioned on an articulated arm that naturally follows operator movements, eliminating the need for active stabilization mechanisms while maintaining image stability relative to the operator's line of sight.
Solution Approach 2:
Instead of stabilizing the camera against operator movements (traditional approach), the patent inverts the approach by having the camera move with the operator's head and body. The mechanical arm with elastic elements allows the camera to follow natural operator movements while maintaining a stable relative position, transforming the problem from active stabilization to passive following.
2Stability of the object's composition
If a stabilization device with articulated arm and counterweight is used, then camera stability is improved, but operator mobility and hands-free operation are reduced
Solution Approach 1:
The mechanical arm serves multiple functions: it positions the camera, provides stabilization through elastic elements, and adapts to different operator movements. The same structure that follows head movements also supports the camera weight and allows hands-free operation, combining positioning and stabilization functions in a single lightweight mechanism.
Solution Approach 2:
The articulated arm with elastic elements creates a dynamic system that adapts to operator movements in real-time. The elastic elements allow the arm to flex and follow natural head and body movements, while the articulated joints enable adjustment to different positions and angles, making the device highly adaptable to various surgical or operational scenarios.
3Device complexity
If manual camera orientation is required, then device complexity is reduced, but image quality and precision are worsened
Solution Approach 1:
The elastic elements act as intermediaries between the operator's movements and the camera position. These elements filter and smooth out abrupt movements while allowing natural following of deliberate positioning, providing passive damping that improves image quality without requiring active control systems or complex stabilization mechanisms.
4Loss of information
If the camera is positioned close to the operator's eyes for subjective shooting, then image representativeness is improved, but device balance and operator comfort are worsened
Solution Approach 1:
The patent positions the camera in three-dimensional space close to the operator's eyes, using the vertical and lateral dimensions to achieve proper positioning without creating excessive forward weight. The articulated arm allows the camera to be positioned above and slightly in front of the operator, distributing weight along the arm structure rather than concentrating it at the front, thereby maintaining balance while achieving subjective shooting perspective.

Function Achieved in This Case
The device provides stable, high-quality images that closely represent the operator's gestures, facilitating training and education by allowing for subjective shooting with reduced operator movement and improved ergonomics.
