Powder Suction Container Control for Clean Precise Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powder dispensing apparatuses, such as the dispenser device described in JP-T-2009-509877, require manual supply using a medicine spoon, leading to potential splashing and contamination of the powder.
Innovation Solution
A powder suction and discharge apparatus comprising a pipe, a container, a valve, a pressure reducing mechanism, and a control unit that controls the suction and discharge of powder through states of valve opening and closing, utilizing negative pressure to store and discharge powder accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual supply using a medicine spoon is used, then the apparatus structure can be simple, but powder splashing and contamination occur
Solution Approach 1:
The patent applies pneumatic principles by using positive and negative pressure mechanisms to automatically suction and discharge powder through a pipe system. The powder supply unit generates negative pressure to suck powder into the container, and the discharge unit generates positive pressure to discharge powder, eliminating the need for manual spooning and preventing contamination.
2Object-affected harmful factors
If automated suction and discharge mechanism is implemented, then powder splashing and contamination are reduced, but the device complexity increases
Solution Approach 1:
The patent merges the powder supply unit and discharge unit into a single integrated powder suction and discharge apparatus. The control unit coordinates both units to work sequentially - first the supply unit fills the container, then the discharge unit empties it - reducing overall system complexity while maintaining automated contamination-free operation.
Solution Approach 2:
The apparatus is designed as a multi-functional unit that can both suction powder into the container and discharge powder from the container using the same basic structure and control system. This universal design reduces device complexity compared to having separate systems for each function.
3Measurement precision
If powder is stored in container, then dispensing accuracy can be improved, but powder adhesion to container walls may occur
Solution Approach 1:
The discharge unit applies vibration to the container during powder discharge. This vibration prevents powder from adhering to the container walls and facilitates complete discharge of the stored powder, maintaining dispensing accuracy while eliminating the adhesion problem.
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 apparatus reduces the likelihood of powder splashing and contamination while ensuring precise and stable discharge with high fluidity, minimizing adhesion to container walls and enabling accurate dispensing.
Implementation Method 1
a pressure reducing mechanism that causes an internal space of the container to have negative pressure
Implementation Method 2
powder is sucked into the container through the pipe

AI summary
A powder suction and discharge apparatus including a pipe, a container that is coupled to the pipe, a valve that opens and closes a passage of the pipe, and a pressure reducing mechanism that causes an internal space of the container to have negative pressure, in which in a first state in which the valve is open and the pressure reducing mechanism is driven, powder is sucked into the container through the pipe, in a second state in which the valve is closed, the sucked powder is stored in the container, and in a third state in which the valve is open, the stored powder is discharged through the pipe.
