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 passive and active damping to stabilize payloads along the z-axis without lateral movement, featuring a compact design suitable for various payloads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional gimbal-based stabilization systems are used, then camera stabilization is achieved, but the system cannot accommodate larger payloads or limited spaces and requires complex structural configurations
Solution Approach 1:
The stabilization system is divided into modular components: a base plate for mounting, a scissor linkage mechanism with multiple interconnected links, and a top plate for payload attachment. This segmentation allows the system to accommodate different payload sizes and configurations while maintaining a relatively simple overall structure.
Solution Approach 2:
The scissor linkage mechanism serves multiple functions: it provides vertical stabilization, allows controlled movement along the z-axis, and can accommodate various payloads through standardized mounting interfaces. The same basic structure can be used for different applications by adjusting the linkage dimensions and mounting options.
2Stability of the object's composition
If levered stabilizing arms with gimbals are used, then vertical damping is created, but the camera follows an arc rather than achieving pure vertical motion
Solution Approach 1:
The scissor linkage mechanism dynamically adjusts the position of the top plate relative to the base plate through controlled movement of the linkage links. This dynamic adjustment allows the system to achieve pure vertical motion by coordinating the movement of multiple links rather than relying on a fixed lever arm that inherently creates arc motion.
3Volume of moving object
If compact stabilization systems are used, then space is saved, but the ability to support heavier payloads is reduced
Solution Approach 1:
The scissor linkage mechanism folds into a compact configuration when not in use, with the top plate and linkage links nesting close to the base plate. This nesting capability allows the system to have a small footprint during storage or transport while still providing adequate support for heavy payloads during operation.
Solution Approach 2:
The system achieves payload support in the vertical dimension through the scissor linkage mechanism while maintaining a compact footprint in the horizontal dimensions. The linkage mechanism extends vertically to provide structural support and stabilization, allowing the system to support heavy payloads without requiring proportional horizontal space.
4Device complexity
If passive scissor linkage mechanisms are used, then structural simplicity is maintained, but dynamic stabilization control is limited
Solution Approach 1:
Sensors detect the position and movement of the top plate relative to the base plate, providing feedback to a control system. The control system processes this information and actuates the scissor linkage mechanism to counteract detected movements, achieving dynamic stabilization control while maintaining a relatively simple mechanical structure.

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.
