Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tissue culture microscope apparatuses experience focus drift due to unmonitored temperature fluctuations of the microscope unit, leading to fuzzy images and positional shifts during cell observation.
Innovation Solution
Incorporating a microscope apparatus with a chamber, humidifier, chamber temperature sensor, microscope temperature sensor, and a determination device that assesses stability of chamber, humidifier, and microscope temperatures to determine if observation is possible, preventing focus drift by ensuring temperature stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If temperature control is exerted only on the chamber without monitoring microscope temperature, then chamber temperature stability is improved, but microscope focus stability deteriorates due to unmonitored temperature fluctuations
Solution Approach 1:
The patent implements temperature monitoring feedback by adding a microscope temperature sensor that continuously measures microscope unit temperature and feeds this information to a determination device. This feedback mechanism enables real-time detection of temperature fluctuations that cause focus drift, allowing the system to monitor and respond to temperature changes affecting focus stability.
Solution Approach 2:
The determination device acts as an intermediary between the temperature sensors and the observation system. It receives temperature data from both the chamber temperature sensor and microscope temperature sensor, processes this information to determine whether temperature conditions are suitable for observation, and provides guidance on when observation should be performed to ensure focus stability.
2Reliability
If multiple temperature sensors and monitoring systems are added to monitor both chamber and microscope temperatures, then focus stability is improved, but device complexity increases
Solution Approach 1:
The determination device serves multiple functions: it receives data from both chamber and microscope temperature sensors, processes temperature information from multiple sources, determines suitability for observation, and provides guidance. This multi-functional approach consolidates what could be separate complex systems into a single integrated device, reducing overall system complexity while maintaining comprehensive temperature monitoring.

AI summary
A microscope apparatus includes: a microscope unit; a chamber, arranged next to the microscope unit, that houses a specimen to be observed by the microscope unit; a humidifier, connected to the chamber, that humidifies the interior of the chamber; a chamber temperature sensor that measures a temperature within the chamber; a microscope temperature sensor that measures a temperature of the microscope unit; and a determination device that determines whether or not observation by microscope is possible based on outputs of the chamber temperature sensor and the microscope temperature sensor.
