Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wet powder is stirred and lifted by rotating stirring blades in a drum container, then the wet powder can be mixed and processed, but the wet powder adheres to the stirring blades
Solution Approach 1:
The stirring blades are equipped with vibration generators that produce vibrations in the direction of the blade length. These vibrations prevent wet powder from adhering to the stirring blades by creating oscillatory motion that disrupts the adhesion between the powder and blade surfaces, ensuring continuous efficient operation without material loss.
2Duration of action of moving object
If the stirring blades rotate continuously at constant speed, then the mixing process is maintained, but the wet powder adheres to the blades and requires manual removal
Solution Approach 1:
Vibration generators mounted on the stirring blades produce vibrations in the blade length direction, which prevents wet powder adhesion during continuous rotation. This eliminates the need for manual powder removal while maintaining continuous mixing operation, significantly improving ease of operation.
3Quantity of substance
If slurry is sprayed in a chamber to remove solvent, then granulated powder with low liquid content is obtained, but the process is very burdensome
Solution Approach 1:
The patent combines the mixing, lifting, and liquid removal functions into a single drum structure with rotating stirring blades. The drum's rotation naturally lifts and drops the wet powder, while vibration generators prevent adhesion. This integrated design achieves liquid content reduction without requiring a separate spray chamber, significantly simplifying the overall process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents wet powder adhesion to stirring blades, allowing for efficient collection and increased yield by using vibrations and controlled rotational changes to separate the powder, thus improving the manufacturing process.
Implementation Method 1
the controller includes control for vibrating the stirring blades. According to this wet powder manufacturing apparatus, the wet powder is separated from the stirring blades by applying vibrations to the stirring blades.
Implementation Method 2
The controller causes the driving device to reduce the rotating speed of the rotary plate at an angle at which the wet powder is dropped from the stirring blades. The wet powder can be separated from the stirring blades utilizing an inertia force when decreasing the rotating speed of the rotary plate.
