Automatic Analyzer Urgent Specimen Priority Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic analyzing apparatuses face challenges in rapidly analyzing urgent biological specimens without interrupting the processing of general specimens, often requiring additional buffering mechanisms that increase size and cost.
Innovation Solution
An automatic analyzing apparatus with a control unit that prioritizes urgent specimens by temporarily unloading general specimens from the sampling line and allowing them to standby, enabling urgent specimens to reach the dispensing position quickly without the need for additional mechanisms or increased size and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a buffering mechanism is added to the analyzing apparatus to enable rapid analysis of urgent specimens, then the analysis speed for urgent specimens is improved, but the device complexity and size increase
Solution Approach 1:
The system dynamically adjusts the processing sequence of specimens based on urgency level. When an urgent specimen is detected, the control unit interrupts the normal processing flow and prioritizes transporting the urgent specimen to the analysis device, while pausing or rescheduling general specimens. This dynamic reconfiguration of the transport schedule enables rapid response to urgent cases without adding physical buffering mechanisms.
Solution Approach 2:
The control unit changes the operational parameters of the transport line by modifying the transport schedule and priority levels. Instead of adding a buffer, the system changes the timing and sequence parameters of specimen transport, allowing urgent specimens to be prioritized through software-controlled scheduling adjustments rather than hardware additions.
2Speed
If a buffering mechanism is added to the analyzing apparatus to enable rapid analysis of urgent specimens, then the analysis speed for urgent specimens is improved, but the apparatus size increases
Solution Approach 1:
The system uses dynamic scheduling to allocate transport line capacity based on specimen urgency. The control unit can pause general specimen transport and redirect the transport line to move urgent specimens优先, effectively creating a virtual buffer through time-based scheduling rather than physical space expansion.
Solution Approach 2:
The existing transport line is made multi-functional by enabling it to handle both urgent and general specimens with different priority levels. The same transport infrastructure serves dual purposes: normal processing for general specimens and expedited processing for urgent specimens, eliminating the need for dedicated buffer space or separate transport paths.
3Reliability
If the buffering mechanism operation is slowed down, then the mechanism can operate reliably, but the rack of the urgent specimen cannot be carried into the analyzing device in time
Solution Approach 1:
The control unit dynamically adjusts the operating speed of the transport line based on specimen urgency. For urgent specimens, the system accelerates the transport speed and prioritizes their movement through the line, while maintaining normal speeds for general specimens. This dynamic speed adjustment ensures urgent cases are handled rapidly without compromising overall system reliability.
Solution Approach 2:
The system implements feedback control by continuously monitoring specimen urgency levels and adjusting transport priorities in real-time. When an urgent specimen is detected, the control unit receives feedback and immediately modifies the transport schedule to prioritize that specimen, ensuring rapid response while maintaining system stability through controlled adjustments rather than abrupt changes.

AI summary
An automatic analyzing apparatus capable of obtaining an analysis result of a specimen high in urgency in a shorter time is provided. When a first rack 50 is present in a sampling line 103 and an analysis request for a second rack higher in the degree of urgency for analysis than the first rack 50 is detected, a control unit unloads the first rack 50 onto a transport line 100 through a return line 102, allows the first rack 50 to stand by at a rack standby position 120 on a transport line 101 between a loading line 101 and the return line 102 under control, and loads the second rack from the transport line 101 onto the sampling line 103 through the loading line 101 and transports the second rack to the dispensing position 111 under control while allowing the first rack 50 to stand by.
