Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical mounts face challenges in maintaining high precision and stability, especially under external loads, due to positional deviations caused by hysteresis during adjustment, which can exceed acceptable tolerance when high precision is required.
Innovation Solution
An optical mount design incorporating clamping units that act independently of manipulator units, allowing for easier manufacturing and reduced complexity, with clamping units arranged between manipulator units to securely fix the inner ring's position relative to the outer ring, utilizing threaded holes and screws with adhesive gaps to maintain the adjustment position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If material connections are designed to be rigid in axial direction and flexible in radial direction, then adjustment sensitivity is improved, but manufacturing complexity increases
Solution Approach 1:
The mount is divided into an outer ring and an inner ring as separate monolithic components. Slots are formed in the base body to create material connections that are bars or arrangements of bars, providing rigid axial support while allowing radial flexibility for adjustment.
Solution Approach 2:
The material connections have different mechanical properties in different directions: they are designed to be rigid in the axial direction to provide stable support, while being flexible in the radial direction to enable effortless adjustment of the inner ring.
2Adaptability or versatility
If adjustment range is increased, then versatility is improved, but adjustment precision deteriorates
Solution Approach 1:
The manipulator units enable dynamic adjustment of the inner ring position with respect to the outer ring. The material connections are designed to be soft in the radial direction, allowing the system to adapt to different adjustment ranges while maintaining precision through the flexibility of the connection design.
3Stability of the object's composition
If clamping units are added to fix inner ring position, then stability is improved, but device complexity increases
Solution Approach 1:
The clamping units are integrated into the monolithic mount structure, combining the functions of positioning and clamping within the same structural framework. The screws are supported in the outer ring and act on the inner ring through the existing material connections, merging multiple functions into a unified design.
Solution Approach 2:
The material connections serve multiple functions: they provide rigid axial support, enable radial flexibility for adjustment, and transmit clamping forces from the screws to fix the inner ring position. This multi-functionality reduces the need for separate components.

Function Achieved in This Case
The solution enhances the stability and precision of the optical mount by minimizing positional deviations and maintaining the adjustment position effectively, while being simpler and less expensive to manufacture compared to prior complex designs.
Implementation Method 1
An adhesive is introduced into the adhesive gap in order to bond the inner ring and the screw to one another
