Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D printing methods require significant space for material handling due to perpendicular and complex movement directions, leading to inefficiencies and increased complexity in device design.
Innovation Solution
A method and device where all material feeding and removal occur in a single spatial direction, reducing the need for additional space and simplifying handling operations by integrating supply devices on the device, allowing for vertical build direction and modular automation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If material handling uses perpendicular and complex movement directions as in existing 3D printing methods, then material can be supplied and removed, but space requirements increase and device complexity increases
Solution Approach 1:
The patent combines multiple material handling operations (material feeding, part removal, support structure removal) into a single linear direction of movement. The construction container is designed to be removable as a complete unit from one side, and materials are supplied through the same side, eliminating the need for perpendicular access paths and reducing the overall device footprint.
Solution Approach 2:
The construction container serves multiple functions: it holds construction material, supports the building process, and acts as a removable unit for part extraction. The support structures within the container perform dual functions of both supporting overhanging features during construction and serving as temporary formwork that is later removed. This multi-functionality reduces the need for separate dedicated components.
2Productivity
If construction containers are manually removed and exchanged from the front using carts, then construction material can be supplied, but the device requires plenty of space in front of the production machine
Solution Approach 1:
The patent changes the dimension of material supply access from horizontal (front access) to vertical (top access). Construction material is supplied from above through the open top of the construction container, eliminating the need for front-side space and carts. The container can be loaded from the top while maintaining compact horizontal footprint.
3Adaptability or versatility
If different handling operations move in perpendicular directions from different sides, then material supply and part removal can be performed, but device complexity increases
Solution Approach 1:
The patent segments the construction container as a separate, removable unit that can be handled as a complete assembly. This segmentation allows the entire container with its material and support structures to be moved together in a single linear direction, rather than requiring complex coordinated movements of multiple components in perpendicular directions. The support structures are also segmented as removable elements within the container.
