Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser cutting and electronic cutting methods using CNC machine tools are limited by their large size, requiring significant space and being unable to handle parts that exceed their own dimensions.
Innovation Solution
A portable soft material cutting device is developed, which includes a main body with a cutting assembly and traction mechanism, cable reeling modules, cable fixtures, and a control module. This device allows for cutting on various-sized parts by moving the main body across a worktable using cables, enabling operation on flat or inclined surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional laser cutting or electronic cutting using CNC machine tools is adopted, then cutting precision and automation are improved, but device size and space occupation increase significantly
Solution Approach 1:
The cutting system is segmented into a portable cutting head unit and a cable reeling control unit. The cutting head contains only essential components (cutting tool, motor, cable reeling module) and can be separated from the control system, allowing it to be transported and used in different locations without requiring a fixed large-scale CNC machine tool installation.
Solution Approach 2:
The invention transitions from a fixed two-dimensional workspace defined by the CNC machine tool table to a flexible three-dimensional workspace where the portable cutting head can move freely over the workpiece using cable reeling mechanisms, enabling cutting of parts that exceed traditional machine tool dimensions.
2Extent of automation
If conventional CNC machine tools are used, then automated cutting capability is improved, but the processing range is limited by the machine tool dimensions
Solution Approach 1:
The cutting head is designed with cable reeling modules that allow dynamic positioning and movement across the workpiece surface. The cables can be reeled in and out to adjust the working radius, enabling the system to adapt to workpieces of various sizes and shapes, including those that would exceed the capacity of fixed CNC machine tools.
Solution Approach 2:
The portable cutting head can be used on various types of work surfaces (flat tables, inclined surfaces, vertical surfaces) and can process workpieces of different sizes by adjusting cable length and reeling configuration, making it universally applicable to a wide range of cutting tasks that traditional fixed CNC machines cannot handle.
3Adaptability or versatility
If a portable design with cable reeling modules is adopted, then device portability and application range are improved, but device complexity increases
Solution Approach 1:
The cable reeling modules are integrated directly into the cutting head assembly, merging the movement control function with the cutting function. This eliminates the need for separate complex positioning systems and reduces overall system complexity while maintaining portability and versatility.
Solution Approach 2:
The cable reeling modules are configured to automatically reel in and out cables based on the cutting head's position and movement, providing self-service positioning without requiring complex external control mechanisms. The system uses the cables themselves as both support and positioning elements, simplifying the overall control architecture.
