Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filling devices require significant effort and conversion when adapting to different container sizes, and they often necessitate manual calibration and positioning, which is inefficient and labor-intensive, especially in clean room environments where high precision and purity are required, such as when filling liquid crystal mixtures.
Innovation Solution
A filling device with a weighing system and a filling needle system that includes a positioning device adaptable to various container diameters, a vertically movable receiving table, and an adjustment unit, allowing for automatic adaptation to different container sizes and enabling inerting and filling without manual relocation or complex conversion processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the filling device is adapted to different container sizes by manual adjustment and conversion, then the filling accuracy can be maintained, but the device complexity and conversion effort increase significantly
Solution Approach 1:
The receiving table is made vertically movable via a linear unit, allowing dynamic adjustment of the table position to accommodate different container sizes. This dynamic positioning eliminates the need for manual conversion of the filling device while maintaining accurate filling, as the system adapts automatically through vertical movement rather than structural reconfiguration.
2Measurement precision
If the filling device requires manual positioning and calibration for different containers, then the filling precision can be ensured, but the productivity and automation level decrease
Solution Approach 1:
The system enables self-service operation where containers are automatically fed onto the movable receiving table and positioned without manual intervention. The linear unit automatically adjusts the table position, and the weighing system continuously monitors filling weight, eliminating the need for manual positioning and calibration while maintaining high filling precision throughout the automated process.
3Measurement precision
If the container position is specified separately for different diameters, then the filling accuracy can be maintained, but the ease of operation and handling effort increase
Solution Approach 1:
The receiving table serves multiple functions: it accommodates containers of different diameters through vertical positioning, provides automatic weighing integration, and enables inerting operations. This universal design allows the same table structure to handle various container types without requiring separate positioning mechanisms or increasing handling effort, as the system adapts to different diameters through its movable capability.
4Adaptability or versatility
If the filling device is converted for each container size change, then the adaptability can be maintained, but the loss of time and efficiency decrease
Solution Approach 1:
The receiving table is pre-configured with vertical movement capability through the linear unit, allowing it to accommodate different container sizes without requiring conversion actions. The system is prepared in advance to handle size variations through its inherent movable design, eliminating conversion time entirely as no reconfiguration is needed when changing from one container size to another.
