Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional liquid suction devices have low efficiency as they can only suck one liquid at a time from a containing box, requiring repeated reciprocating motions to suck and inject liquids into reaction cups, leading to inefficient liquid handling.
Innovation Solution
A liquid suction device with multiple rotating liquid suction mechanisms that revolve around a central axis, allowing simultaneous suction from multiple containing cavities, with each mechanism having a unique circular track to cover multiple cavities, improving suction speed and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional liquid suction device sucks one liquid at a time from a containing box, then the structure is simple, but the liquid suction efficiency is low
Solution Approach 1:
The device divides the single suction mechanism into multiple independent suction mechanisms (first liquid suction mechanism, second liquid suction mechanism, etc.), each capable of independently suctioning liquid from different containing cavities. This segmentation allows simultaneous operation across multiple cavities, directly resolving the contradiction between simplicity and efficiency by organizing complexity into functional modules.
Solution Approach 2:
The patent transitions from a single-point suction approach to a multi-point spatial distribution approach by arranging suction mechanisms at different positions and orientations. The rotating units with circular tracks enable coverage of multiple containing cavities in three-dimensional space, adding spatial dimensionality to the suction process and achieving parallel liquid handling.
2Loss of time
If a single liquid suction mechanism reciprocates to suck multiple liquids, then the device structure is simple, but the suction time is long
Solution Approach 1:
The device pre-positions multiple liquid suction mechanisms at different locations with circular rotation tracks, enabling them to simultaneously access multiple containing cavities before the suction process begins. This preliminary spatial arrangement eliminates sequential reciprocating motions and allows parallel suction operations, significantly reducing total suction time.
Solution Approach 2:
Multiple liquid suction mechanisms operate continuously and simultaneously on different containing cavities, eliminating idle time between suction operations. While one mechanism is injecting liquid, others continue suctioning from different cavities, ensuring continuous productive action throughout the entire liquid handling process.
3Productivity
If multiple liquid suction mechanisms are used to suck liquids from different containing cavities simultaneously, then the liquid suction efficiency is improved, but the device complexity increases
Solution Approach 1:
Each liquid suction mechanism is designed as a universal module capable of performing both suction and injection functions, with the same basic structure (suction unit, rotating unit, driving unit) used across all mechanisms. This multi-functionality reduces overall device complexity by avoiding specialized components for different operations, while still achieving high productivity through parallel execution.
Solution Approach 2:
The patent combines multiple identical or similar liquid suction mechanisms into a single integrated device, sharing common components such as the supporting piece, control system, and power supply. This merging approach achieves the productivity benefits of multiple mechanisms while mitigating complexity through standardized, modular design and shared infrastructure.
