Test Device Resuming Biological Material Testing After Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test devices for biological materials often interrupt testing due to malfunctions, leading to incomplete data and resource wastage, as they lack the ability to resume or continue tests after power failures or faulty operations.
Innovation Solution
A test device equipped with a memory to store test progress information and an auxiliary power supply, allowing the controller to reboot and resume tests from the interrupted step, ensuring continuity of testing even after power interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the test device is equipped with memory and auxiliary power supply to resume interrupted tests, then the reliability and continuity of testing is improved, but the device complexity and cost increase
Solution Approach 1:
The memory unit stores test progress information before power failure or interruption occurs, and the auxiliary power supply pre-charges to maintain memory operation during power loss. This preliminary preparation enables the controller to retrieve stored progress and resume testing without restarting from the beginning, thereby improving testing continuity while adding only minimal additional components
Solution Approach 2:
The system creates a digital copy of the test progress state in the memory unit, which can be retrieved and used to restore the testing process. This copying mechanism allows the system to recover from interruptions without requiring complex redundant hardware, as the critical information is replicated in storage rather than requiring duplicate operational systems
2Loss of information
If the test device stores detailed test progress information in memory, then the ability to resume tests accurately is improved, but the loss of information during power failure increases without protective measures
Solution Approach 1:
The auxiliary power supply pre-charges to sufficient capacity before power failure occurs, creating an energy cushion that maintains memory operation during the transition period. This beforehand preparation ensures that test progress information is preserved in the memory unit even when main power is lost, preventing data loss while the system determines whether to resume or restart testing
3Productivity
If the controller automatically resumes interrupted tests using stored information, then productivity and time efficiency are improved, but the risk of continuing faulty test procedures increases
Solution Approach 1:
The controller retrieves stored test progress information and provides feedback to determine whether the test can be safely resumed. The system analyzes the stored data to identify the interruption point and assesses whether resuming will produce valid results, or whether a complete restart is necessary. This feedback mechanism enables automatic resumption of valid tests while preventing continuation of faulty procedures, thereby maintaining both productivity and test validity
Data Source
AI summary
A test device and a method for controlling the test device are disclosed. After a test is interrupted due to a malfunction of the test device, the test device continuously performs the interrupted testing. The test device for testing a biological material includes: a memory configured to store information which relates to progress of a test; and a controller which, if the test is interrupted due to a malfunction of the test device, is configured to continue performance of the test by using the information which relates to the test progress which is stored in the memory.
