Rotatable Carousel Alignment for Multifunctional Ophthalmic Apparatus
Solution Overview
Problem
Existing ophthalmic diagnostic equipment faces challenges in efficiently aligning multiple devices on the optical axis of a patient's eye during examinations, leading to reduced accuracy and prolonged sessions due to limited adjustment possibilities and potential discomfort.
Innovation Solution
A multifunctional ophthalmic apparatus with a rotatable carousel system and motorized adjustments allows for precise alignment of multiple devices along a horizontal rotation axis, combined with height and depth adjustments, eliminating the need for lateral displacement and enabling fast, accurate examinations by aligning optical axes without repeated alignment procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple ophthalmic devices are mounted on a rotatable carousel system, then the adjustment speed and examination efficiency are improved, but the measurement precision and alignment accuracy deteriorate due to limited adjustment possibilities
Solution Approach 1:
The patent transforms the static carousel system into a dynamic one by adding motorized adjustment mechanisms. The carousel can now perform both rotation and lateral displacement along the optical axis, enabling active adaptation to different examination requirements while maintaining alignment precision across multiple device positions.
Solution Approach 2:
The invention adds a new dimension of movement to the carousel system. Instead of only rotational positioning, the carousel gains lateral displacement capability along the optical axis (depth direction), creating a two-degree-of-freedom positioning system that simultaneously improves both efficiency and precision.
2Adaptability or versatility
If devices are repositioned on the optical axis between measurements, then different eye characteristics can be examined, but the examination time increases and patient discomfort increases due to repeated alignment procedures
Solution Approach 1:
The motorized carousel system performs preliminary positioning actions automatically before each measurement. The system pre-aligns the appropriate device on the optical axis through coordinated rotation and lateral displacement, eliminating the need for manual realignment procedures between different examination types.
Solution Approach 2:
The carousel system serves itself by automatically positioning the correct device without requiring external intervention. The motorized mechanisms enable the system to self-adjust and self-align between measurements, reducing both examination time and patient discomfort.
3Measurement precision
If autonomous and independent device support is used, then each device can be precisely aligned, but the device complexity and structural requirements increase
Solution Approach 1:
The patent merges multiple independent device support functions into a single integrated carousel structure. The carousel combines rotational positioning, lateral displacement, and device mounting capabilities in one unified mechanism, reducing overall structural complexity while maintaining individual device alignment precision through coordinated movement.
