Specimen Processing Device State Transition Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional specimen processing devices face inefficiencies in power consumption and user operation, particularly during the transition from an inactivated to an activated state, leading to wasteful power usage and reduced work efficiency in medical settings.
Innovation Solution
The implementation of a specimen processing device with a state transition mechanism that automatically detects the presence of a specimen container and releases the pause state upon user instruction, allowing for immediate processing without requiring manual reactivation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the device transitions to an inactivated state to suppress power consumption, then power consumption is reduced, but the device requires a preparation period before processing can resume
Solution Approach 1:
The system performs preliminary actions by pre-loading patient information and pre-warming the pneumatic source during the pause state transition. When a patient information registration is detected, the system proactively prepares the processing unit by loading necessary data and initiating warm-up sequences, so that when the user eventually inputs the start instruction, the preparation period is significantly reduced or eliminated.
2Reliability
If the user waits for the preparation operation to complete before instructing start, then the device is ensured to be in a processable state, but work efficiency in medical coding is lowered
Solution Approach 1:
The system provides self-service by automatically monitoring its own operational state and detecting when it has completed the necessary preparation. The processing unit continuously checks whether the pneumatic source has reached the required temperature and whether patient information is fully loaded, then automatically transitions to the ready state and notifies the user, eliminating the need for the user to wait passively or repeatedly check the device status.
Solution Approach 2:
The system implements feedback mechanisms by providing real-time status information to the user interface, indicating when the device is ready for operation. The control unit monitors the preparation progress and communicates the current state (e.g., 'warming up', 'ready', 'processing') to the user, allowing the user to understand when it is appropriate to input the start instruction without unnecessarily waiting or re-checking.
3Use of energy by moving object
If the device automatically returns to inactivated state after pause release, then power consumption is suppressed during non-use, but the user must re-input startup instruction after finishing other works
Solution Approach 1:
The system dynamically adjusts its operational state based on real-time conditions. Instead of a fixed automatic return to inactivated state, the processing unit monitors whether a patient information registration has been detected and whether the preparation is complete. If preparation is complete, the system maintains or transitions to a ready state even during pause, allowing the user to resume work immediately after finishing other tasks without re-inputting startup instructions. This dynamic state management balances power consumption with operational convenience.
