Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stone cutting devices face issues with maintaining consistent tension in cutting tools, leading to deformation, reduced durability, and increased production costs due to inadequate spacer systems, resulting in suboptimal cutting quality and increased workpiece loss.
Innovation Solution
A stone cutting device with a frame unit that individually adjusts tension in cutting tools and incorporates spacers to maintain gaps between them, allowing movement in the length direction while constraining movement in the width direction, enabling the application of a high load of 8 to 27 tons per cutting tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If spacers are used to maintain gaps between cutting tools, then the cutting tools are constrained from moving in the width direction, but the spacers prevent tension from being applied intact to the cutting tools
Solution Approach 1:
The spacer is divided into two distinct functional portions: a gap maintenance portion that maintains the gap between cutting tools, and a tension transmission portion that transmits tension from the actuator to the cutting tool. This segmentation allows each portion to optimize its specific function without interfering with the other, resolving the contradiction between gap maintenance and tension application.
Solution Approach 2:
The tension transmission portion acts as an intermediary element between the actuator and the cutting tool. It transfers the tension force generated by the actuator to the cutting tool while allowing the gap maintenance portion to independently maintain the required gap. This intermediary function enables both gap maintenance and effective tension application to coexist.
2Manufacturing precision
If high tension is applied to cutting tools to improve cutting quality, then cutting precision improves, but tool deformation and durability issues increase
Solution Approach 1:
The system dynamically adjusts the tension applied to each cutting tool individually through actuators, allowing optimization of cutting precision for each tool based on its specific condition and position. This dynamic control enables high tension to be applied when needed for precision while preventing excessive or uneven tension that would cause deformation and reduce durability.
Solution Approach 2:
The tension parameter for each cutting tool can be individually adjusted and optimized. By changing the tension parameter to appropriate levels rather than applying uniform high tension to all tools, the system achieves high cutting precision while maintaining tool durability through controlled, optimized tension levels.
3Productivity
If multiple cutting tools are used to increase productivity, then cutting speed improves, but maintaining consistent tension across all tools becomes difficult
Solution Approach 1:
Each cutting tool is equipped with its own dedicated actuator and spacer assembly, creating independent tension control segments. This segmentation allows each cutting tool's tension to be adjusted and maintained independently, ensuring consistent tension across all tools even when multiple tools operate simultaneously, thereby maintaining both high productivity and tension consistency.
Solution Approach 2:
Each cutting tool position has its own localized tension control system with individual actuators. This local quality approach ensures that each tool receives the appropriate tension independently, maintaining tension consistency across the entire multi-tool system while enabling high productivity through parallel operation of multiple properly tensioned tools.
