Modular CNC Machine for Portable 3D Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable and dismountable CNC machines for three-dimensional digitization lack automation and motorization, making them neither precise nor efficient for high-definition scanning, and existing folding systems complicate assembly and transport.
Innovation Solution
A dismountable and motorized 3D scanning CNC machine with three Cartesian axes, featuring a longitudinal bedplate, base, column, crosspiece, and arm that fold onto a transport tool, along with a 3D scanning sensor and control equipment, allowing for easy assembly, disassembly, and precise scanning while enabling efficient movement and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the machine is made portable and dismountable, then ease of transport is improved, but automation and motorization are lost
Solution Approach 1:
The machine is divided into modular components (base, column, crosspiece, arm, scanning sensor) that can be easily assembled and disassembled. Each component maintains its motorized and automated functions while allowing portable transport when disconnected.
Solution Approach 2:
The machine transitions between two states: a compact disassembled state for portable transport, and an assembled operational state with full automation and motorization. This dynamic reconfiguration allows both portability and automated functionality.
2Ease of operation
If existing folding systems are used, then portability is improved, but assembly and dismantling become complicated
Solution Approach 1:
The machine uses clearly defined modular segments (base, column, crosspiece, arm) with standardized connection interfaces, simplifying assembly and dismantling compared to integrated folding systems.
Solution Approach 2:
Instead of folding the entire machine as a single unit (which complicates assembly), the invention disassembles it into separate modular components that can be easily connected and disconnected at standardized interfaces.
3Ease of operation
If the machine is disassembled for transport, then ease of movement is improved, but scanning precision may be affected
Solution Approach 1:
The scanning sensor and its support structure are separated as distinct modular components with standardized connection interfaces, ensuring precise and repeatable reassembly that maintains scanning accuracy.
Solution Approach 2:
The machine includes pre-positioned connection elements and alignment features that ensure accurate reassembly of components, guaranteeing that scanning precision is maintained after disassembly and reassembly for transport.
