Composite Laminating Device Cutting Section Groove Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing composite material automatic laminating devices require a complex structure to cut composite material sheets to short lengths, leading to material wastage and the need for manual removal of excess material.
Innovation Solution
A composite material automatic laminating device with a cutting section positioned close to the compaction roller, utilizing a blade that inserts into grooves on the compaction roller to cut the material in the width direction, and a control device to manage the cutting process, allowing for precise and efficient cutting of short lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the cutting section is disposed at a position away from the compaction roller, then the structure is simpler, but the composite material sheet piece cannot be cut to have a short length
Solution Approach 1:
The blade of the cutting section is inserted into the groove of the compaction roller, with the blade nested within the groove structure. This allows the cutting function to be integrated at the compaction roller location without requiring additional space, enabling short length cutting while maintaining structural simplicity
Solution Approach 2:
The cutting function is merged with the compaction roller by positioning the cutting section adjacent to the compaction roller and inserting the blade into the groove. This combines two functions (compaction and cutting) at the same location, eliminating the need for separate cutting sections and reducing overall device complexity
2Manufacturing precision
If a thin toe control module is used to cut the composite material sheet piece to have a short length, then the cutting precision is improved, but the structure becomes complicated
Solution Approach 1:
Instead of using a complex thin toe control module with multiple components, the invention extracts only the essential cutting function and implements it with a simple blade inserted into the compaction roller groove. This removes unnecessary complexity while retaining the core cutting capability
Solution Approach 2:
The blade is designed as a simple, replaceable component that can be easily replaced when worn, rather than using a complex, expensive control module. This approach prioritizes simplicity and ease of replacement over long-term durability, reducing overall system complexity
