Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic film product manufacturing methods require large manufacturing footprints, are inefficient in handling spatial differences between pre-printed rolls, and necessitate frequent machinery realignment and maintenance.
Innovation Solution
A film processing station with interchangeable, independently operable modules on a supporting rail, dynamically coordinated by a controller, which clamps, cuts, and seals plastic film into finished products, accommodating roll misalignments and enabling modular, compact, and efficient production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple processing stations with different machinery are used to produce finished plastic film products, then the manufacturing capability is improved, but the manufacturing footprint becomes large
Solution Approach 1:
The patent combines multiple processing functions (cutting, sealing, welding, zipper attachment) into a single integrated processing station. Different toolheads performing various operations are mounted on one shared carriage system that travels along a common rail, allowing multiple functions to be performed in a compact footprint rather than requiring separate stations spread out in space.
Solution Approach 2:
The carriage assembly serves multiple functions by being able to accommodate different toolheads for various operations. The same carriage and rail infrastructure supports cutting tools, sealing tools, welding tools, and zipper attachment tools, making the system universal and adaptable to different processing needs without requiring separate dedicated machinery for each function.
2Ease of repair
If the entire film product manufacturing line is stopped to perform maintenance on multiple pieces of different machinery, then the maintenance quality is improved, but the production time increases
Solution Approach 1:
The system is divided into modular, independently replaceable toolheads that can be serviced or replaced without stopping the entire manufacturing line. Each toolhead can be quickly detached and replaced on the carriage, allowing maintenance to be performed on individual components rather than requiring shutdown of the whole system.
Solution Approach 2:
The system allows for quick changeover and maintenance through standardized interfaces and rapid toolhead replacement mechanisms. The carriage and rail system is designed to facilitate easy access and replacement of components, enabling operators to perform maintenance tasks quickly and efficiently with minimal disruption to production.
3Manufacturing precision
If pre-printed film rolls are misaligned with respect to the film processing machinery, then the realignment precision is improved by stopping and realigning all machinery, but the production continuity is worsened
Solution Approach 1:
The system uses sensors and control systems to monitor the position and alignment of the film web in real-time. This feedback information is used to dynamically adjust the positioning of the carriage and toolheads to compensate for misalignment between different film rolls, maintaining precise cutting and sealing positions without requiring manual intervention or production stoppage.
Solution Approach 2:
The carriage assembly is designed with dynamic positioning capabilities that allow it to adjust its position along the rail in real-time based on film roll alignment variations. This dynamic adjustment enables the system to accommodate creep and misalignment between pre-printed rolls while maintaining consistent processing quality and continuous production.
4Area of stationary object
If interchangeable, independently operable modules are used on a supporting rail, then the space requirements are reduced, but the system complexity increases
Solution Approach 1:
The processing system is divided into modular, independently operable toolheads that can be selectively mounted on the carriage. Each module performs a specific function and can be quickly attached or detached, allowing the system to be configured for different production needs while maintaining a compact footprint. The modular design simplifies maintenance and changeover despite the sophisticated functionality.
