Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test apparatus for fluidic samples face errors due to inconsistent pressure application during inspection, leading to potential leaks or inadequate sample transfer, which can affect inspection results.
Innovation Solution
A test apparatus with a sensing unit to detect the position of a driving unit, ensuring consistent pressure is applied to the cartridge through a motor-driven pressing member, using a proximity or weight sensor to recognize the position and control the movement for uniform pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pressure is increased to ensure sample transfer, then transfer reliability is improved, but leakage risk increases
Solution Approach 1:
The patent implements a feedback control system where a sensor detects the position of the pressing member, and this position information is fed back to the control unit. The control unit adjusts the driving unit's operation based on this feedback to maintain consistent pressure within a predetermined range, preventing both leakage and insufficient transfer.
Solution Approach 2:
The patent dynamically adjusts the pressure parameter by controlling the position of the pressing member through the driving unit. The control unit modifies pressure parameters in real-time based on sensor feedback, ensuring pressure remains within the optimal range for reliable transfer without causing leakage.
2Adaptability or versatility
If manual operation is used to perform inspection processes, then flexibility is maintained, but inspection accuracy deteriorates due to human error
Solution Approach 1:
The patent implements automation where the control unit autonomously controls the pressing member's movement and pressure application based on sensor feedback. This self-service mechanism eliminates human error in pressure control while maintaining operational flexibility through programmable control sequences.
Solution Approach 2:
The patent replaces manual mechanical operation with an automated electromechanical system. The driving unit, controlled by the control unit based on sensor feedback, substitutes human operators in controlling pressure and movement, thereby improving inspection accuracy while maintaining flexibility through programmable control.
3Device complexity
If pressure is applied inconsistently to the cartridge, then device simplicity is maintained, but inspection reliability deteriorates
Solution Approach 1:
The patent introduces a feedback loop where the sensor detects the pressing member's position and provides this information to the control unit. This feedback mechanism enables consistent pressure control without requiring complex manual intervention, as the system self-regulates based on detected position.
Solution Approach 2:
The control unit serves multiple functions: it controls the driving unit's movement, processes sensor feedback, and adjusts pressure parameters. This multi-functionality allows consistent pressure control without proportionally increasing device complexity, as a single control unit handles multiple control tasks.
