Wire Cutting Orientation for Gravity-Based Part Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wire cutting apparatuses for separating parts from a base plate are laborious and costly, as they are not designed for automation or efficient collection of parts, particularly in additive manufacturing processes like DMLS, where parts protrude vertically and are difficult to collect manually.
Innovation Solution
A wire cutting apparatus that holds the base plate in a separation position such that parts protrude vertically downwards, allowing them to fall by gravity into a collecting element, enabling automated and efficient collection, with a holding device and separation element that can move relative to each other and a collecting element designed to receive and segregate the parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If parts protrude vertically upwards from the base plate in conventional wire cutting apparatus, then the additive manufacturing process can be maintained, but the parts become difficult to collect manually and automation is cumbersome
Solution Approach 1:
The holding device is configured to hold the base plate in a separation position such that parts protruding from the base plate point vertically downwards along a gravitational vector, inverting the conventional upward protrusion orientation. This inversion enables parts to fall automatically into a collecting element positioned below, achieving full automation without complex collection systems
2Productivity
If manual collection of parts is used, then no additional automated collection systems are needed, but the process becomes laborious and costly
Solution Approach 1:
The system uses gravity as a free resource to enable parts to fall automatically into the collecting element without requiring manual collection or complex automated handling systems. The holding device configures the base plate orientation so that parts naturally descend along the gravitational vector, making the collection process self-service and eliminating laborious manual operations
3Extent of automation
If the base plate is held in conventional orientation, then the additive manufacturing process remains unchanged, but parts cannot fall naturally and require dedicated collection systems
Solution Approach 1:
The holding device inverts the base plate orientation during the separation process, configuring it to hold parts protruding vertically downwards along the gravitational vector. This simple inversion eliminates the need for dedicated and expensive automated collection systems, achieving full automation with minimal device complexity
Solution Approach 2:
The invention replaces complex mechanical collection systems with a gravity-based passive collection mechanism. By orienting the base plate so parts fall naturally along the gravitational vector, the system substitutes expensive automated handling machinery with a simple gravity-driven collection process
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates a fully automated and cost-effective system for collecting and processing parts, reducing manual labor and enhancing the efficiency of additive manufacturing processes by allowing parts to fall naturally into a well-defined collection area.
Implementation Method 1
the holding device is configured to hold the base plate in the separation position in such a manner, that the at least one part protruding from the base plate points vertically downwards, i.e. along a gravitational vector. Thus, parts separated from the base plate will automatically fall in a well-defined direction, i.e. downwards, driven by gravity
