Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing composite machining systems require multiple specialized machines and lengthy setup times due to the integration of laser machining and cutting processes, which complicates workflow and increases workspace requirements.
Innovation Solution
A composite machining machine with a portal structure incorporating a first machining head for additive manufacturing and a second machining head for cutting, where the machining heads are movable within defined regions, and a region definition member that can be opened or closed to separate the additive and cutting processes, allowing for efficient integration of both operations in a single machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple specialized machines are used for additive manufacturing and cutting, then machining precision and reliability are maintained, but workspace requirements and setup time increase
Solution Approach 1:
The patent combines additive manufacturing and cutting operations into a single composite machining machine with an integrated portal structure. The first machining head performs additive manufacturing while the second machining head performs cutting, both within the same machine footprint. This merging eliminates the need for multiple separate specialized machines, reducing workspace requirements while maintaining machining precision through dedicated machining heads for each operation.
Solution Approach 2:
The composite machining machine is designed as a multi-functional system that can perform both additive manufacturing and cutting operations. The portal structure supports multiple machining heads that can be positioned and operated independently, allowing the single machine to fulfill multiple machining functions that previously required separate specialized equipment.
2Area of stationary object
If laser machining and cutting processes are integrated in a single machine, then workspace is reduced, but setup time and device complexity increase
Solution Approach 1:
The machine is segmented into distinct functional modules: a portal structure supporting multiple independent machining heads, each dedicated to specific operations. The first machining head is configured for additive manufacturing while the second is configured for cutting. This segmentation allows each machining head to be optimized for its specific function while being integrated into a unified portal structure, managing device complexity through modular design.
Solution Approach 2:
The machining heads are designed to be movable and repositionable within the portal structure, allowing dynamic configuration for different operations. The heads can be moved into position as needed, enabling the system to adapt between additive manufacturing and cutting operations without requiring permanent fixed installations for each function.
3Area of stationary object
If additive and cutting processes are performed in the same region, then workspace is minimized, but contamination of machining heads occurs
Solution Approach 1:
The working region is segmented into distinct zones using a region definition member that can be opened or closed. When performing cutting operations, the region definition member closes off the cutting region to prevent metal chips and coolant from contaminating the additive manufacturing region and the first machining head. This spatial segmentation maintains compact workspace while protecting equipment through controlled access between regions.
Solution Approach 2:
The region definition member acts as an intermediary barrier between the cutting region and the additive manufacturing region. It can be closed during cutting operations to isolate the two processes, preventing contamination while allowing the machine to operate in a compact footprint. The intermediary structure enables both operations to share the same overall workspace without direct interference.

AI summary
A composite machining machine includes a first machining head, a second machining head, a workpiece holder, a cover, and a frame. The first machining head is movable in a first region to perform additive manufacturing on the workpiece in a second region. The second machining head is movable in the second region to perform cutting on the workpiece. The workpiece holder holds the workpiece in the second region. The cover covers the first region. The frame includes two columns and a beam member coupling the columns. The cover includes a region definition member openable at least partially. The region definition member defines the second region. The first machining head is movable in a guided manner in a range between the columns. The beam member is disposed so that the predetermined range lies inside the first region, and outside and above the second region.
