Microscope Dual Cover System for Light and Heat Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing microscope apparatus faces challenges in accurately capturing weak light due to external light interference and heat transmission from internal components, which affects image quality and sample positioning.
Innovation Solution
The apparatus incorporates a dual cover system with a second light source positioned on the second cover, which can be closed to prevent external light and heat from reaching the sample, allowing for precise imaging with reduced vibrations and increased imaging efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a single cover is used to enclose the sample setting unit, then the structure is simple, but external light can enter through gaps and heat is transmitted to the sample
Solution Approach 1:
The patent employs a nested cover structure where a first cover and a second cover are arranged in layers, with the second cover positioned within the first cover. This nested configuration creates multiple barriers against external light and heat transmission to the sample, effectively resolving the issue of harmful factors penetrating through a single cover while maintaining structural organization.
Solution Approach 2:
The enclosing structure is segmented into multiple functional covers: the first cover provides initial protection and housing, while the second cover specifically addresses light shielding and thermal insulation. This segmentation allows each cover to be optimized for its particular function, with the second cover being movable between open and closed positions to control access to the sample.
2Object-affected harmful factors
If the cover is kept closed to block external light, then light shielding is improved, but sample positioning and adjustment become difficult
Solution Approach 1:
The second cover is designed as a movable component that can dynamically switch between an open position (allowing easy access for sample positioning and adjustment) and a closed position (providing effective light shielding). This dynamic design resolves the contradiction by allowing the system to adapt its state based on operational requirements, ensuring both ease of operation and light shielding effectiveness.
3Illumination intensity
If light is irradiated from above the sample, then imaging is enabled, but external light enters through gaps and weak light cannot be accurately captured
Solution Approach 1:
The nested dual-cover structure creates multiple layers of light blocking barriers. The first cover provides the primary enclosure, while the second cover adds an additional layer specifically optimized for light shielding. This nested arrangement ensures that even when the first cover has gaps, the second cover prevents external light from reaching the sample, thereby enabling accurate detection of weak light signals during imaging.
4Ease of operation
If the cover is open to allow sample adjustment, then ease of operation is improved, but external light enters and affects image quality
Solution Approach 1:
The enclosing system is segmented into two functional covers with distinct roles. The first cover remains open or accessible during sample adjustment to maintain ease of operation, while the second cover can be closed to provide light shielding when imaging is performed. This segmentation allows the system to separately optimize for both operational accessibility and light protection, resolving the contradiction between ease of operation and harmful factor prevention.
