Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic analyzers face challenges with reagent bottle loading and unloading mechanisms due to variations in component fabrication, leading to unstable positional relationships and increased operator workload for adjustments, which can result in operational failures.
Innovation Solution
An automatic analyzer equipped with a reagent storage unit, reagent transport unit, reference members, sensors, and a controller that adjusts transport parameters based on detected positions using sensors like reflection sensors, cameras, or laser displacement meters to stabilize the reagent bottle mounting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic reagent bottle loading and unloading mechanism is implemented, then operator workload is reduced and analysis interruption is minimized, but positional displacement occurs due to fabrication variations and aging, causing mounting errors and operational failures
Solution Approach 1:
The patent employs sensors (optical sensors, encoders, or vision systems) to detect the actual position of reagent bottles and mechanical components during loading and unloading operations. This position information is fed back to the control unit, which automatically adjusts transport parameters to compensate for deviations, ensuring accurate mounting despite fabrication variations and aging effects
Solution Approach 2:
The control unit dynamically modifies transport parameters (such as transport distance, speed, or positioning coordinates) based on detected position deviations. By changing these parameters in real-time, the system adapts to positional variations caused by manufacturing tolerances and component aging, maintaining reliable reagent bottle mounting
2Manufacturing precision
If manual adjustment of mechanism positions is performed to compensate for fabrication variations, then mounting accuracy is improved, but operator workload increases
Solution Approach 1:
The system performs self-adjustment through automated detection and correction mechanisms. Sensors automatically detect position deviations, and the control unit autonomously calculates and applies correction parameters without requiring operator intervention. This eliminates manual adjustment work while maintaining high mounting accuracy
Solution Approach 2:
The patent replaces manual mechanical adjustment operations with automated sensing and control systems. Instead of operators physically adjusting component positions, the system uses optical sensors, encoders, or vision systems to detect positions and electronically controls motorized components to achieve accurate mounting, substituting human labor with automated systems
