Carousel Safety Light Curtain for Continuous Slide Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital slide scanning apparatuses pose safety hazards for operators due to moving parts and risk of damaging glass slides when handling hundreds of slides, as existing systems lack effective safety measures to prevent accidents and slide damage.
Innovation Solution
A digital slide scanning apparatus with a slide rack carousel equipped with a safety light curtain that disables the carousel's rotation upon detecting an object or improperly positioned slides, ensuring operator safety and slide protection through continuous loading and unloading without a door, and utilizing a multi-color status indicator for slide rack slots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a door is installed to enclose the carousel for safety, then operator safety is improved, but vibration is increased and continuous loading is hindered
Solution Approach 1:
The patent removes the door enclosure from the system entirely, extracting the source of vibration while maintaining safety through an alternative approach (light curtain). This allows continuous loading/unloading of slide racks without the destabilizing effect of a door mechanism.
Solution Approach 2:
The patent introduces a light curtain as an intermediary safety mechanism between the operator and the moving carousel. This optical barrier provides safety protection without the mechanical constraints of a door, allowing the carousel to remain open for continuous operation while still preventing accidental contact.
2Productivity
If the carousel rotates continuously to process multiple slides, then productivity is improved, but safety hazards increase for operators interfacing with moving parts
Solution Approach 1:
The light curtain is positioned to detect objects before the carousel rotates into positions that could cause harm. The system performs preliminary detection and can pause rotation before an object enters the hazard zone, preventing accidents while maintaining continuous processing capability.
Solution Approach 2:
The light curtain provides real-time feedback to the control system about the presence of objects near the carousel. This feedback loop allows the system to automatically adjust rotation behavior, pausing or reversing when objects are detected, thereby maintaining safety while preserving productivity through automated response.
3Productivity
If multiple slide racks are loaded into the carousel to process hundreds of slides, then productivity is improved, but the risk of slide damage from moving parts increases
Solution Approach 1:
The light curtain detects the presence of slide racks and glass slides before the carousel begins rotation or before moving parts approach them. This preliminary detection allows the system to prevent movement that could cause damage to valuable slides while maintaining the ability to process large batches.
Solution Approach 2:
The light curtain acts as an intermediary protective layer between the moving carousel mechanism and the fragile glass slides. By detecting the presence of slides and preventing inappropriate movement, it provides protection without requiring physical barriers that would interfere with the scanning process.
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 accidents by disabling the carousel's rotation when objects or improperly positioned slides are detected, ensuring operator safety and reducing the risk of slide damage, while allowing continuous loading and unloading for efficient operation.
Implementation Method 1
A carousel also includes a safety light curtain that operates to disable the motor that rotates the carousel when the presence of an object (e.g., the fingers of an operator) is detected within a predetermined area of the carousel.

AI summary
A digital slide scanning apparatus includes a safety light curtain that operates to disable the motor that rotates the carousel when the presence of an object (e.g., the fingers of an operator) is detected within a predetermined area of the carousel. The light curtain also operates to disable the motor that rotates the carousel when an improperly positioned glass slide or slide rack is detected. The digital slide scanning apparatus also includes a multi-color status indicator for each rack slot that indicates the rack slot location of an improperly positioned glass slide or slide rack.
