Waste Chute Segmented Louvers for Analyzer Contamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waste disposal systems in automatic analysis devices are prone to contamination, require excessive force for consumable transfer, and have a high susceptibility to errors, leading to increased costs and reduced system availability.
Innovation Solution
A waste disposal system with a waste chute featuring self-resetting slats forming at least two slat rings, spaced apart to allow consumables to stack and be pushed into the waste container with minimal force, reducing contamination and error susceptibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If multiple slat rings are arranged close together in the waste chute, then consumables are contained better, but the force required to push consumables through the waste chute becomes excessively high
Solution Approach 1:
The waste chute is segmented into distinct sections by spacing the first slat ring and second slat ring at different positions along the waste chute, creating intermediate space for consumable stacking while maintaining containment functionality
Solution Approach 2:
The solution transitions from arranging slat rings in a densely packed configuration to spacing them apart along the longitudinal dimension of the waste chute, utilizing the available space more efficiently to reduce resistance while maintaining containment
2Ease of operation
If a complex multi-part electric gripper is used for cuvette transfer, then gripping functionality is improved, but device complexity and error susceptibility increase
Solution Approach 1:
The invention extracts and eliminates the complex multi-part electric gripper from the waste delivery system, replacing it with a simpler mechanism that achieves the same functional goal of transferring consumables to the waste container
Solution Approach 2:
The waste delivery system is designed to automatically push consumables into the waste container using the spaced slat ring configuration, eliminating the need for complex electric gripper mechanisms and reducing system dependency on sophisticated actuation systems
3Stability of the object's composition
If slat rings are positioned close together, then consumable containment is improved, but contamination risk inside the waste chute increases
Solution Approach 1:
The waste chute is divided into functional zones by positioning the first slat ring for initial containment and the second slat ring for final containment before the waste container, with spaced intermediate region that reduces contamination pressure
Solution Approach 2:
The spaced region between the first slat ring and second slat ring acts as an intermediary zone that allows controlled consumable movement and stacking while preventing direct contact and contamination between consumables and the waste chute walls
