Optics Platform Swing-Arm Control for Fine Motion Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optics platforms struggle with fine motion adjustments, particularly in high-magnification devices like telescopes and cameras, due to environmental forces such as wind and vibration, which can cause devices to lose focus or require significant re-alignment.
Innovation Solution
The optics platform features a base plate with a swing arm and pivot arm that allow for semi-circular horizontal and vertical movements, constrained by interlocking end members and biasing members like springs, enabling precise and independent control of the device's position through windage and elevation knobs, and a ball mount attachment for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing optics platforms are used, then basic support function is provided, but fine motion adjustments are insufficient due to environmental forces
Solution Approach 1:
The platform is divided into multiple independent adjustment mechanisms: azimuth adjustment for horizontal positioning, elevation adjustment for vertical positioning, and tilt adjustment for angular correction. Each mechanism operates independently to provide precise control over different degrees of freedom, enabling fine motion adjustments while maintaining stability against environmental disturbances.
2Difficulty of detecting and measuring
If high-magnification devices are used, then viewing capability is improved, but sensitivity to movement increases making focus difficult to maintain
Solution Approach 1:
The platform provides differentiated adjustment capabilities for different operational needs: coarse adjustment mechanisms for rapid positioning and fine adjustment mechanisms for precise focus maintenance. The azimuth and elevation knobs provide controlled motion ranges suitable for high-magnification devices, while the tilt mechanism addresses specific angular corrections needed for optimal viewing.
3Stability of the object's composition
If stable support is provided, then device stability is improved, but fine motion control capability is reduced
Solution Approach 1:
The platform incorporates dynamic adjustment mechanisms that allow the system to transition between stable and movable states. The azimuth and elevation knobs enable controlled motion when adjustment is needed, while the interlocking mechanisms and friction-based holding provide stability when positioning is complete. This dynamic capability allows the platform to adapt between providing fine motion control and maintaining stable support.

Implementation Method 1
A spring is contained within a spring hole in the base plate and applies force to the swing arm
Implementation Method 2
A pivot arm is pivotally attached to the swing arm to articulate in a semi-circular motion around a horizontal axis of the swing arm
