Microscope Objective Protection Ring with Drainage Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective devices for microscope components fail to provide effective protection against liquids while maintaining accessibility and ease of cleaning, as they often restrict operation and are difficult to clean manually, especially in cases of contamination.
Innovation Solution
A protective device comprising an objective protection ring with a radially protruding lower ring area forming a free space to prevent capillary effects, combined with a stand protector featuring a drainage channel, which allows for effective liquid drainage without hindering the operation or accessibility of microscope components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sleeves are used to cover objectives and extend over the casing surface, then liquid protection is improved, but accessibility to control elements and ease of cleaning deteriorate
Solution Approach 1:
The protective device is divided into separate components: objective protection rings that can be individually placed on objectives, and a revolver cover with drainage channel. This segmentation allows the protection system to be applied without covering control elements on objectives, maintaining accessibility while providing liquid protection.
Solution Approach 2:
The drainage function is extracted from the protective covering and implemented as a separate drainage channel in the revolver cover. This allows the protection rings to be minimal and not extend over control elements, while liquid is still effectively managed through the dedicated drainage system.
2Reliability
If sealing rings are arranged around objectives and contact the revolver cover, then liquid protection is improved, but ease of cleaning deteriorates due to difficult manual cleaning
Solution Approach 1:
The drainage channel is designed to passively collect and drain liquid away from protected components without requiring active pumping or complex mechanisms. Liquid naturally flows into the channel and is drained, making the system self-cleaning to a large extent and easy to maintain.
Solution Approach 2:
The protective components are designed with smooth, non-porous surfaces that do not absorb liquid, making them visually distinct when contaminated and easy to clean. The simple geometric forms allow liquid to be easily wiped or rinsed away without penetrating into the structure.
3Reliability
If protective devices cover large areas of the objective surface, then liquid protection is improved, but device complexity increases
Solution Approach 1:
Rather than using a single large protective cover, the system uses individual protection rings for each objective and a separate revolver cover. This segmentation reduces the complexity of each individual component while achieving comprehensive liquid protection across the entire objective area.
Solution Approach 2:
The protection rings are designed as thin, flexible annular elements that can be easily manufactured and installed. These simple ring structures provide effective liquid barriers without requiring complex three-dimensional forms, reducing manufacturing and assembly complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents liquid ingress through capillary forces, ensuring superior liquid protection while maintaining full accessibility and ease of cleaning, even in cases of contamination, by creating a free space that negates capillary effects and utilizing a drainage channel for efficient liquid management.
Implementation Method 1
The objective protection ring (10) comprises a lower ring area (14) located below the contact area (12) and protruding further outwards radially than the contact area (12) so as to form a free space in the inward direction. In this way, a capillary effect is prevented.

AI summary
A protective device for protecting microscope components from contact with a liquid comprises at least one objective protection ring for arrangement around an objective, wherein the objective protection ring comprises an annular contact area for contacting the objective; and a stand protector with a drainage channel for draining a liquid. The objective protection ring comprises a lower ring area located below the contact area and protruding further outwards radially than the contact area in order to form a free space in the inward direction.
