Bag Making Apparatus Parallel Transport Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag-making apparatuses require a lot of floor space due to the perpendicular arrangement of the tube-forming device and processing stations, which is inefficient in rectangular production halls.
Innovation Solution
The transport direction of tubular material in the tube-forming device and tube pieces is oriented parallel to each other, allowing for a space-saving setup by using a deflecting device to change the direction of the tubular material before the cross cutter, enabling the tube-forming device and processing stations to be arranged in a line, reducing unnecessary space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tube-forming device and processing stations are arranged perpendicular to each other, then the processing stations can easily access the tube pieces, but the apparatus requires a lot of floor space
Solution Approach 1:
The patent changes the spatial arrangement from a perpendicular (2D plane) configuration to a linear (1D line) configuration by orienting the transport direction of tubular material parallel to the transport direction of tube pieces. This dimensional reorganization allows the tube-forming device and processing stations to be arranged in a line rather than perpendicular to each other, reducing the floor space requirement while maintaining processing accessibility
Solution Approach 2:
The patent introduces a deflecting device that can dynamically change the transport direction of the tubular material from its original direction to a direction parallel with the tube piece transport. This dynamic directional adjustment enables the system to optimize space utilization while maintaining the functional relationship between the tube-forming device and processing stations
2Area of stationary object
If the transport direction of tubular material is changed to be parallel with tube pieces, then the apparatus becomes more compact, but a deflecting device is required to alter the direction
Solution Approach 1:
The patent introduces a deflecting device as an intermediary element between the tube-forming device and the cross cutter. This intermediary component facilitates the directional change of tubular material from its original transport direction to a direction parallel with the tube pieces, enabling the compact linear arrangement without directly modifying the core processing functions
Solution Approach 2:
The deflecting device serves multiple functions: it changes the transport direction of tubular material, enables compact space utilization, and maintains compatibility with the existing cross cutter and processing stations. By making this single component multi-functional, the patent minimizes the overall system complexity despite the directional change requirement
