Dosing Unit Clamping Module for Automated Material Loosening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dosing devices require complex and expensive manual mechanisms for securing and rotating dosing units, which can lead to operational safety issues and inefficient material loosening, especially when handling toxic substances.
Innovation Solution
A dosing device with a pretensioned clamping module and a spreading module that allows for automated secure fastening and loosening of the dosing unit, using a clamping module with spring elements and a spreading mechanism to ensure the dosing unit remains attached during pivoting and impact movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual retaining ring mechanism is used to secure the dosing unit, then the dosing unit can be held in place, but the device complexity and cost increase significantly
Solution Approach 1:
The patent replaces the complex manual mechanical retaining ring mechanism with an automated magnetic field-based securing system. The magnetic field acts on ferromagnetic elements in the dosing unit to hold it securely in the receptacle, eliminating the need for manual pivoting, linear displacement, and fixing operations. This substitution dramatically simplifies the device structure while maintaining reliable securing of the dosing unit.
2Ease of operation
If gentle pivoting movement is used to loosen dosing material, then the dosing unit can be repositioned, but the material loosening effectiveness is insufficient
Solution Approach 1:
The patent implements a periodic action sequence where the dosing unit is first gently pivoted for repositioning, then subjected to repeated impact movements. This periodic alternation between gentle pivoting and forceful impact effectively loosens compacted dosing material from the container walls, combining the benefits of both movement types for optimal material discharge.
Solution Approach 2:
The impact movements generate mechanical vibrations that propagate through the dosing unit and its contents, disrupting compacted material structures and facilitating efficient loosening. This vibration-based approach is far more effective than gentle continuous motion for breaking up adhered dosing material.
3Ease of operation
If manual operation is used for securing and rotating dosing units, then operational control is maintained, but operational safety decreases when handling toxic substances
Solution Approach 1:
The system performs securing, impact generation, and dosing operations automatically without requiring manual intervention. The automated sequence eliminates human exposure to toxic substances while maintaining precise control over the dosing process. The magnetic field-based securing and automated impact mechanisms operate independently, creating a safe enclosed system for handling hazardous materials.

AI summary
A dosing device for dosing free-flowing substances comprises a support column and a horizontal support arm (10) projecting from the support column, which has a holding unit (20) on which at least one movably mounted receiving unit (30) is arranged, in which at least one dosing unit (70) can be inserted or removed from this receiving unit (30), wherein the holding unit (20) contains at least one motion actuator (50) acting on the receiving unit (30). The dosing unit (70) can be attached to the receiving unit (30) by means of a pre-tensioned clamping module (60), wherein the clamping module (60) can be expanded from a dosing position to a feeding position by means of a spreading module (40) assigned to the holding unit (20) for the purpose of inserting and/or removing the dosing unit (70), and the spreading module (40) is decoupled from the receiving unit (30) in the dosing position.
