Solution Overview
Problem
Current immunofluorescence (IF) processing methods face challenges such as coverslip handling errors, inadequate specimen moisture, and light-induced signal corruption, leading to unreliable and reproducible results.
Innovation Solution
A specialized dish storage device with built-in features like opaque exterior protection from light, water reservoirs for humidity maintenance, and universal coverslip processing platforms that securely hold and process both small and larger coverslips, reducing the need for repetitive handling and minimizing the risk of specimen damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If coverslips are handled repeatedly with forceps during staining and processing, then processing can be completed, but specimen damage and handling errors increase
Solution Approach 1:
The patent combines multiple coverslips (up to six 12mm coverslips or two larger coverslips) onto a single processing platform, allowing simultaneous handling and processing. This merging approach reduces the number of separate forceps operations needed while maintaining complete control over all specimens, thereby improving both productivity and specimen integrity.
Solution Approach 2:
The processing platform acts as an intermediary between the coverslips and the user's hands/forceps. By securing coverslips to the platform and manipulating the platform itself, the system reduces direct forceps-to-coverslip interactions that cause damage, while still enabling all necessary processing steps.
2Ease of operation
If standard transparent petri dishes are used for storage and incubation, then visibility is good, but light exposure degrades fluorescent signals
Solution Approach 1:
The dish is designed with differentiated optical properties in different regions: the lid and exterior walls are opaque to block light and protect fluorescent signals, while the bottom remains transparent to allow microscopic observation of coverslips during processing and storage.
3Reliability
If water saturated cloths are placed in petri dishes to humidify storage environments, then moisture is maintained, but the setup is time-consuming and inefficient
Solution Approach 1:
The patent integrates the humidity control function directly into the dish structure by incorporating water reservoirs as built-in features of the dish itself, rather than requiring separate external humidification sources. This integration eliminates setup time while maintaining reliable humidity control.
Solution Approach 2:
The dish's built-in water reservoirs automatically maintain humidity through evaporation, making the system self-regulating without requiring user intervention to add water or adjust humidification settings.
4Reliability
If makeshift platforms are fabricated from lab supplies and affixed with adhesives, then airflow under coverslips is enabled, but the modification process is time-consuming and unreliable
Solution Approach 1:
The patent combines the platform structure and airflow channels into a single integrated component that is permanently formed during manufacturing. This eliminates the need for separate fabrication steps involving adhesives and assembly, reducing both time and potential failure points.
Applied Scientific Principles

Function Achieved in This Case
The solution provides an optimal IF environment, reducing errors and inefficiencies in coverslip processing, leading to high-quality staining and reduced antibody consumption, thereby enhancing the reliability and efficiency of IF processing.
Implementation Method 1
Two rectangular built-in reservoirs along the inside bottom of the dish surface store water to ensure adequate humidity within the chamber during storage and incubation periods
Implementation Method 2
The prospective opacity of the dish exterior protects fluorescent samples from degrading due to light exposure

AI summary
This IF Moisture Chamber and Workstation related processes result in an optimal environment that reduces risk of poor quality IF staining & processing outcomes. This workstation results in less antibody consumption and end to end processing costs reduction for standard IF staining protocols. The universal dish and imbedded devices are multipurpose and can be reused to simultaneously process up to six small circular 12 millimeter diameter coverslips or two standard larger sized circular or square coverslips This workstation eliminates the need to use a forceps to precisely grasp, hold, move and tilt each individual coverslip multiple times for fluid removal during a series of repetitive staining and dumping activities typically required for full processing of each coverslip. Consequently this device facilitates exceeding storage and processing standards correlated with high quality coverslips' specimens staining for subsequent mounted slides placed under microscopic examination and image capture of specimen cell structures and compositions.
