Modular Roll-Holder Accessory for Numerical Control Cutting Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roll-holder structures for numerical control cutting machines are bulky, logistically challenging, and heavy, especially when handling materials with high specific weight like leather, limiting their repositioning and storage.
Innovation Solution
A slim accessory apparatus with fixable beams attached to the cutting machine, supporting rolls via main and secondary slots, allowing for easy assembly, quick mounting, and reduced weight distribution through discharge feet, enabling efficient unrolling of multiple rolls at different heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional roll-holder structures are used, then rolls can be supported and fed to the machine, but the overall dimensions become large and the structure becomes heavy
Solution Approach 1:
The roll-holder structure is divided into separate components: a fixed support structure attached to the machine and removable beams that can be detached and stored. This segmentation allows the main structure to remain lightweight while the removable beams provide additional support when needed.
Solution Approach 2:
The beam support structure is designed to be removable and reconfigurable rather than fixed. The beams can be detached from the fixed support structure and repositioned as needed, transforming the system from a static heavy structure to a dynamic lightweight system that provides support only when required.
2Adaptability or versatility
If traditional roll-holder structures are used, then rolls can be supported at different heights, but the structure complexity increases
Solution Approach 1:
The support structure is segmented into a fixed base structure and removable beams that can be independently positioned. Each beam can be separately attached to the fixed structure at different locations, allowing flexible height configuration without requiring a complex integrated support system.
Solution Approach 2:
The fixed support structure is pre-configured with attachment points at various heights and positions. This preliminary arrangement of support points allows the removable beams to be quickly attached in different configurations without requiring complex assembly procedures, simplifying the overall system while maintaining versatility.
