Integrated Calibration Stand for Optical Observation Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual attachment and alignment of calibration objects for surgical microscopes are time-consuming, prone to errors, and require additional equipment, making calibration methods cumbersome and often not performed, especially for untrained users, which affects the accuracy of diopter settings, camera calibrations, and stand kinematics.
Innovation Solution
A stand for optical observation units with a calibration object permanently integrated or attached in a fixed location, allowing for automated alignment and recording by the connected camera, reducing the need for manual intervention and additional equipment, and enabling automated calibration methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual attachment and alignment of calibration object is performed, then calibration accuracy can be achieved, but time consumption and operational complexity increase significantly
Solution Approach 1:
The calibration object is pre-integrated onto the stand in a fixed location during manufacturing, so that no manual attachment or alignment is required during calibration operations. The calibration object is already in its correct position and orientation before the calibration process begins.
Solution Approach 2:
The stand automatically provides the calibration object in the correct position without requiring external intervention. The integrated calibration object serves itself by being permanently mounted, eliminating the need for operators to manually attach and align separate calibration objects.
2Measurement precision
If manual alignment of calibration object is performed, then calibration can be carried out, but error susceptibility increases for untrained users
Solution Approach 1:
The calibration object is pre-positioned and securely mounted on the stand during manufacturing, ensuring correct alignment before use. This eliminates the need for operators to perform manual alignment operations that could introduce errors.
Solution Approach 2:
The stand automatically provides the calibration object in the correct position without requiring external intervention. The integrated calibration object serves itself by being permanently mounted, eliminating the need for operators to manually attach and align separate calibration objects.
3Adaptability or versatility
If separate calibration equipment is used, then calibration functionality is provided, but device complexity and cost increase
Solution Approach 1:
The calibration object is merged with the stand structure itself, becoming an integral part of the device. This eliminates the need for separate, standalone calibration equipment and reduces the overall system complexity.
Solution Approach 2:
The stand serves multiple functions: it supports the optical observation unit during normal operation and simultaneously provides the calibration object for calibration operations. This multi-functionality eliminates the need for dedicated calibration equipment.

AI summary
To simplify the optical calibration of an optical observation apparatus, a stand for an optical observation unit including a calibration object arranged directly on the stand in a fixed location is specified. Moreover, an optical observation apparatus, which includes such a stand and an optical observation unit connected to the stand, a method for calibrating such an optical observation apparatus, and a computer program are specified.
