Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixing devices face issues with contamination from foreign matter ingress and difficulty in sealing the container, making them unsuitable for precision fields like chemistry and biology, and require improved mixing stability and reduced mixing time.
Innovation Solution
A mixing device that rotates a mixing container with two rotating shafts, featuring a guide module, rotating module, and tilting module, allowing the container to be sealed and mixed by simultaneous rotation and tilting, with additional features like elasticity, vibration, and sensing units for safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional vortex-type mixing device is used, then mixing can be achieved, but the container cannot be sealed allowing foreign matter ingress and contamination
Solution Approach 1:
The mixing container is designed to rotate dynamically around two axes (first rotation axis vertical, second rotation axis horizontal) rather than remaining stationary. This dynamic rotation enables effective mixing of solution and powder precipitate while maintaining a sealed container structure, eliminating the need for open-top vortex mixing designs.
Solution Approach 2:
The mixing action is transitioned from a single-axis vertical rotation to dual-axis rotation (vertical axis + horizontal tilt axis). By adding the second rotation dimension, the system achieves thorough mixing capability that previously required an open container, now enabling sealing while maintaining mixing effectiveness.
2Reliability
If a sealed container is used for precision mixing, then contamination is prevented, but mixing stability and precipitation suppression become difficult
Solution Approach 1:
The container rotates around a vertical first rotation axis and simultaneously tilts around a horizontal second rotation axis. This dynamic dual-axis motion creates continuous fluid circulation patterns that prevent powder precipitate from settling, maintaining mixing stability and suppressing precipitation within the sealed container environment.
Solution Approach 2:
The dual-axis rotation system generates controlled mechanical motion and vibration patterns that keep the powder precipitate suspended in the solution. The combination of vertical rotation and horizontal tilting creates turbulent flow patterns that prevent particle settling and maintain homogeneous mixing.
3Productivity
If traditional single-axis rotation is used, then device simplicity is maintained, but mixing time is extended and stability is reduced
Solution Approach 1:
By adding the second rotation axis (horizontal tilt) to the traditional single vertical rotation axis, the system achieves three-dimensional mixing motion. This dimensional enhancement dramatically reduces mixing time by creating more effective fluid circulation patterns and prevents stability issues that occur with single-axis rotation, justifying the increased mechanical complexity.

AI summary
A mixing device includes: a guide module which has a preset length, to which the mixing container is rotatably seated along a longitudinal direction and to which the mixing container is selectively fixed to be attachable and detachable; a rotating module which is provided on the guide module and selectively rotates the mixing container so that a first rotation axis is formed along the vertical direction of the mixing container; and a tilting module which is formed long along the vertical direction, has a second rotation axis on both sides along a width direction of the guide module, is rotatably coupled, and selectively rotates the guide module in the vertical direction to tilt the mixing container in a direction intersecting the first rotation axis.
