Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stabilization systems for cameras and weaponry fail to provide effective vertical stabilization, especially on moving vehicles, and are limited by size, weight, and structural configuration, often requiring complex gimbal mechanisms that cannot accommodate larger payloads or limited spaces.
Innovation Solution
A vertically stabilized platform using scissor linkages and struts with integrated shock absorbers and springs, allowing for compact, single-axis vertical stabilization without deviations, and optionally incorporating active damping through IMU-controlled systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional gimbal mechanisms with levered stabilizing arms are used, then some vertical damping can be achieved, but the camera follows an arc instead of pure vertical motion and the system cannot accommodate larger payloads
Solution Approach 1:
The patent transitions from arc-based stabilization in a limited dimensional space to pure vertical motion by introducing a novel scissor linkage mechanism that operates in a different dimensional configuration. The scissor linkages enable the platform to move strictly along the vertical Z-axis, eliminating the arc trajectory constraint of traditional gimbal systems and expanding the operational dimensional space for payload stabilization.
Solution Approach 2:
The patent replaces the traditional gimbal mechanism with a scissor linkage-based mechanical system. This substitution eliminates the need for complex gimbal assemblies and levered arms, providing a more versatile platform that can accommodate larger payloads while maintaining vertical stabilization through a different mechanical approach that allows pure vertical motion.
2Stability of the object's composition
If nested frames with multiple rotating axes are used, then multi-axis stabilization can be achieved, but the system becomes complex and cannot accommodate larger cameras or weaponry
Solution Approach 1:
The patent extracts and eliminates the complex nested frame structures with multiple rotating axes from the stabilization system. By removing these unnecessary complex components and focusing solely on vertical stabilization through scissor linkages, the system achieves simplified structural configuration while maintaining effective stabilization capability for larger payloads.
Solution Approach 2:
Instead of using multiple rotating axes nested within each other, the patent inverts the approach by using a parallel scissor linkage mechanism that achieves stabilization through a different structural arrangement. This inverted configuration reduces complexity by eliminating nested frames while providing adequate stabilization for various payloads including cameras and weaponry.
3Stability of the object's composition
If levered stabilizing arms with gimbals are used, then vertical damping can be provided, but space is required that is not available in limited environments like truck beds or ship cabins
Solution Approach 1:
The patent employs dynamic scissor linkage mechanisms that can adjust and adapt to available space while providing vertical damping. The scissor linkages allow for compact configuration in limited spaces such as truck beds or ship cabins, yet can extend and provide full stabilization functionality when needed, making the system volume adaptable rather than fixed and large.
Solution Approach 2:
The patent utilizes parameter changes in the scissor linkage mechanism to adjust the system's physical dimensions and configuration. By varying the extension and compression of the scissor linkages, the system can adapt its volume to fit within limited spaces while maintaining the vertical damping capability, effectively changing the operational parameters of the mechanism to suit different spatial constraints.

AI summary
Embodiments of the inventive subject matter are directed to vertically stabilized platforms. These platforms have a top portion that moves only along a single axis (e.g., vertically up and down), and a bottom portion that remains stationary relative to a reference frame. The top portion is coupled with the bottom portion by scissor linkages that are all configured to slide on one end to allow the top portion to move up and down without any perturbations or movements along any other axes. Stabilization in some embodiments is accomplished by incorporating struts that couple with both the bottom portion (either directly or indirectly) and two of the scissor linkages. Struts can include both a damper and a spring and can be selected based on anticipated load to be stabilized. Embodiments can be mounted on, e.g., truck beds, ships, or other surfaces that can move, giving rise to a need for a stabilized platform.
