Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging machines for pharmaceutical, cosmetic, and food products face limitations in dosing multiple products at room temperature without exposure to heat, leading to product deterioration, and have restricted production capacity due to their design and layout.
Innovation Solution
A packaging machine with a forming station that creates four-weld bags from a plastic sheet, a separate filling and closing station for dosing products at room temperature, and a movement system that aligns and transfers bags orthogonally to ensure all parts of the bags are cooled before filling, allowing for multiple product dosing without increasing machine length and enabling high production speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vertical packaging machines use dispensing tubes to dose products into bags, then high production speed is achieved, but the product is exposed to heat from welding means causing deterioration
Solution Approach 1:
The packaging machine is divided into separate functional modules: a forming module for creating bags, a dosing module for filling products, and welding means for sealing. This segmentation allows the dosing operation to occur at a distance from the heat-generating welding means, preventing thermal exposure to the product while maintaining high-speed production capabilities
Solution Approach 2:
The patent introduces an intermediary transfer mechanism (such as a conveyor system or transfer arms) that moves bags from the forming station to the dosing station and then to the welding station. This intermediary transport system enables thermal isolation between the product dosing area and the heat-generating welding area, allowing high-speed operation without heat exposure
2Device complexity
If dosing device is placed above welding means to save space, then machine compactness is improved, but the product tank is heated by welding heat causing product deterioration
Solution Approach 1:
The dosing device is separated from the welding means into a distinct module positioned at a different location in the production line. This spatial segmentation eliminates thermal interference while maintaining operational efficiency, as the dosing module can be positioned in a cooler zone away from the welding heat source
Solution Approach 2:
Instead of arranging components vertically in a compact stack that places the dosing device above the welding means, the patent transitions to a horizontal or distributed spatial arrangement. This dimensional reconfiguration allows adequate thermal separation between the dosing device and welding means while preserving machine footprint efficiency through optimized layout
3Adaptability or versatility
If multiple dosing stations are arranged in succession along horizontal direction, then multiple products can be dosed, but machine length increases significantly
Solution Approach 1:
Multiple dosing stations are arranged in a nested or stacked configuration where dosing units are positioned vertically or in overlapping horizontal spaces. This nesting approach allows multiple products to be dosed simultaneously or in rapid sequence without proportionally increasing the overall machine length, as the dosing stations share common infrastructure and space
4Productivity
If vertical packaging machines make multiple vertical bag rows to increase production, then productivity is improved, but the machine length is constrained by limited space
Solution Approach 1:
The patent transitions from a purely vertical arrangement of multiple bag rows to a configuration that utilizes horizontal spreading and three-dimensional space more effectively. By distributing bag rows across multiple levels or in a staggered horizontal-vertical pattern, the machine achieves high production capacity without requiring excessive length, as the layout optimizes the use of available volumetric space
