Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing analyzing devices face challenges in achieving sufficient acceleration for mixing and agitation of small fluid amounts in a short time, leading to inefficient operations and potential insufficiency in mixing and agitation, especially with complex configurations requiring additional sensors and motors.
Innovation Solution
An analyzing apparatus with a rotational drive section comprising a first drive part for rotating the device, a second drive part for reciprocating the device, and a third drive part for engaging and disengaging the first and second drive parts to achieve necessary acceleration, allowing for stable engagement and controlled agitation without additional sensors for agitation control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the analyzing device is rotated using only the first drive part, then the device structure is simple, but sufficient acceleration for mixing and agitation cannot be obtained
Solution Approach 1:
The patent combines the first drive part (rotation drive) and second drive part (reciprocation drive) into a single analyzing device. The first drive part rotates the turntable, while the second drive part reciprocates the analyzing device along the rotation direction, creating synergistic acceleration that exceeds what either drive part could achieve alone.
Solution Approach 2:
The patent introduces dynamic reciprocating motion through the second drive part, which moves the analyzing device back and forth along the rotation direction. This dynamic adjustment of motion patterns enables rapid acceleration and deceleration phases that significantly enhance mixing and agitation effectiveness.
2Reliability
If additional drive parts and sensors are added to achieve sufficient acceleration, then mixing and agitation performance is improved, but the device configuration becomes complex and control is complicated
Solution Approach 1:
The second drive part serves multiple functions: it reciprocates the analyzing device to enhance acceleration, works in conjunction with the first drive part during rotation, and can be selectively engaged or disengaged based on operational requirements. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The third drive part acts as an intermediary mechanism that selectively engages and disengages the second drive part from the first drive part. This mediator component enables controlled interaction between the two drive parts without requiring complex direct coupling mechanisms or additional sensors for coordination.
3Productivity
If the analyzing device is rotated at high speed continuously, then centrifugal separation efficiency is improved, but mixing and agitation of small fluid amounts becomes insufficient
Solution Approach 1:
The second drive part implements periodic reciprocating motion during the rotation cycle, creating alternating phases of acceleration and deceleration. This periodic action disrupts continuous high-speed rotation, introducing mixing and agitation cycles that prevent fluid stagnation while maintaining overall centrifugal separation efficiency.
Solution Approach 2:
The coordinated operation of the first and second drive parts ensures continuous useful action throughout the rotation cycle. While the first drive part maintains continuous rotation for centrifugal separation, the second drive part continuously reciprocates to provide ongoing mixing and agitation, ensuring both functions operate simultaneously without interruption.

AI summary
Disclosed is an analyzing apparatus including a first drive part (71) for rotating a turntable (101) on which an analyzing device is set, a second drive part (72) selectively engaged with the first drive part (71) to reciprocate the analyzing device, and a third drive part (73) for relatively moving the first drive part (71) and the second drive part (72) a position where the first and second drive parts are engaged with each other and a position where the first and second drive parts are not engaged with each other. Thus in the mixing and agitation of a small amount of fluid, necessary acceleration can be obtained even in a short time.
