Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for processing rod-shaped workpieces, such as window or door profiles, lack flexibility and efficiency in tool access, leading to increased processing time and reduced reliability due to the need for multiple tools and fixed tool orientations.
Innovation Solution
The device features machining tools arranged on pitch circle segments that can move in circular paths relative to the workpiece, allowing for flexible access and positioning, with tools capable of moving in X, Y, and Z directions, and being adjustable in height, enabling machining at various angles and positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple fixed tools are provided on a carrier element, then different drilling and milling operations can be performed, but processing time increases and flexibility is reduced
Solution Approach 1:
The patent applies the dynamics principle by replacing fixed tools with a dynamic system where a single tool can move along circular paths (pitch circle segments) to reach different positions on the workpiece. The tool carriers are movable on these circular paths, allowing the same tool to perform multiple operations at different locations, thereby reducing the number of tools needed and decreasing processing time while maintaining versatility.
Solution Approach 2:
The patent implements universality by designing a single tool to perform multiple functions through its ability to move along pitch circle segments and access different positions on the workpiece. The tool can drill, mill, or perform other operations at various angular positions around the workpiece, making one tool replace multiple fixed tools and significantly reducing tool changeover time.
2Extent of automation
If tools are arranged on a carrier element perpendicular to movement direction, then automated processing is enabled, but tool access flexibility to the workpiece is limited
Solution Approach 1:
The patent applies dimensionality change by introducing circular motion paths (pitch circle segments) for the tools, adding a rotational dimension to the otherwise linear automated transport system. This allows tools to access the workpiece from multiple angular positions around the circumference, greatly enhancing access flexibility while maintaining automated processing through coordinated motion control.
3Adaptability or versatility
If multiple different drills and milling tools are provided, then various machining operations can be performed, but device complexity increases
Solution Approach 1:
The patent reduces device complexity by replacing multiple specialized tools with a single universal tool that can perform drilling, milling, and other machining operations by moving to different positions on the pitch circle segments. This universal tool approach maintains full machining capability while significantly reducing the number of tools and associated complexity.
