Storage Container Discharge Structure for Accurate Piece Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blister machines face issues with electrostatic charging of small piece goods during separation, leading to sticking and incorrect dispensing of drug or food supplement portions due to frictional electricity, resulting in inaccurate drug combinations.
Innovation Solution
A storage container with a discharging device having a projection and contactor that electrically couples to a dispensing station, reducing electrostatic charge by discharging it into the dispensing station, ensuring all pieces are available for separation and dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If small piece goods are separated in the storage container, then dispensing accuracy is improved, but electrostatic charging occurs leading to sticking and incorrect dispensing
Solution Approach 1:
The patent applies the 'Blessing in disguise' principle by introducing a discharging device that converts the harmful electrostatic charge into a beneficial effect. The discharging device includes a projection extending into the upper portion of the housing and a contactor that electrically couples to the dispensing station, actively neutralizing the electrostatic charge generated during separation of small piece goods, thereby preventing sticking and ensuring accurate dispensing
2Reliability
If a discharging device is added to reduce electrostatic charge, then sticking is prevented, but device complexity increases
Solution Approach 1:
The patent applies the 'Merging' principle by integrating the discharging device directly into the storage container structure. The projection and contactor are combined with the housing and separating device, forming a unified assembly that eliminates the need for separate external discharging equipment, thereby minimizing additional complexity while maintaining dispensing reliability
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 minimizes electrostatic charge on small piece goods, preventing sticking and ensuring accurate dispensing by continuously discharging the charge, thus maintaining the integrity of drug or food supplement combinations.
Implementation Method 1
