Innovation Solution
A microscope objective lens switching device utilizing a turntable base, a disc surface, a driving assembly, and a transmission assembly with a worm, worm gear, and a roller bearing assembly that includes outer and inner bearings with cylindrical rollers, supporting the disc surface's rotation via balls and rollers for enhanced precision and reduced processing requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a layer of balls is adopted between a supporting disc surface and a base of the objective lens switching device to support rotation, then rotation is enabled, but the position accuracy of the turntable base deteriorates and material/processing requirements increase
Solution Approach 1:
The support structure is segmented into two distinct systems: an outer ring with balls for supporting disc surface rotation, and an inner ring with a roller bearing assembly for supporting worm gear rotation. This segmentation allows each subsystem to be optimized independently, with the outer ball support providing rotation ease while the inner roller bearing maintains high position accuracy for the turntable base.
Solution Approach 2:
The roller bearing assembly acts as an intermediary between the worm gear and the turntable base, providing a high-precision rotation support mechanism. This intermediary component isolates the precision requirements from the broader rotation system, allowing the turntable base to maintain high position accuracy while still enabling smooth rotation through the roller bearing's intermediate support function.
2Ease of operation
If a layer of balls is adopted to support rotation, then rotation is enabled, but the cost of material and processing increases
Solution Approach 1:
The support structure is divided into two zones with different support mechanisms: the outer ring uses balls for rotation support where high precision is less critical, while the inner ring uses a roller bearing assembly where precision is paramount. This segmentation allows cost optimization by applying simpler, cheaper ball support where sufficient and reserving expensive precision roller bearings only where absolutely necessary.
Solution Approach 2:
Different support qualities are applied to different locations: the outer ring receives ball support with relaxed precision requirements, while the inner ring receives roller bearing support with high precision requirements. This local differentiation of quality matches the functional requirements of each region, reducing overall manufacturing costs while maintaining necessary performance.
3Ease of operation
If a layer of balls is adopted to support rotation, then rotation is enabled, but the performance of the finished objective lens switching device deteriorates
Solution Approach 1:
The rotation support is segmented into two independent systems: an outer ball support system for general rotation and an inner roller bearing system for precision transmission. This segmentation ensures that the performance-critical worm gear rotation is isolated and supported by the high-reliability roller bearing, while the outer ball support handles less critical rotation aspects.
Solution Approach 2:
The roller bearing assembly serves as a high-reliability intermediary that mediates between the worm gear and turntable base, ensuring accurate and reliable power transmission. This intermediary component protects the overall system performance by providing a stable, high-precision rotation interface that is not susceptible to the limitations of ball support.
