Horizontal-arm CMM Tilted Upright for Compact Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and disassembly of large coordinate measuring machines for transportation are time-consuming and costly due to their size, making it impractical to deliver them assembled.
Innovation Solution
A horizontal-arm coordinate measuring machine design that allows the upright to be tipped and folded onto the base, reducing overall dimensions for easier transportation, by removing screws connecting the central body to the side shoulders and using a bracket to lock the upright in place, thus avoiding costly disassembly and reassembly operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the coordinate measuring machine is designed with large dimensions to provide sufficient measuring volume, then the measuring capability is improved, but the transportation and assembly become more difficult and costly
Solution Approach 1:
The machine is divided into separable components (base, upright, arm assemblies) that can be independently handled during transportation. The upright can be detached from the base, and the arm can be separated from the second carriage, allowing each segment to be transported and reassembled more easily
Solution Approach 2:
The upright is designed to be tiltable and foldable, changing its spatial configuration from an extended vertical position to a folded position alongside the base. This dimensional transformation reduces the overall footprint from a large extended configuration to a compact folded configuration suitable for transportation
2Volume of moving object
If the coordinate measuring machine is designed with large dimensions to provide sufficient measuring volume, then the measuring capability is improved, but the transportation cost and complexity increase
Solution Approach 1:
The upright is pre-equipped with tilting and folding mechanisms, and the arm is pre-designed with detachable connections. These preliminary structural arrangements enable straightforward disassembly and reassembly operations without requiring complex procedures or specialized equipment
Solution Approach 2:
The machine structure is segmented into modular components with standardized connection interfaces, simplifying the assembly and disassembly processes while maintaining the large measuring volume capability
