Modular Excavation Machine Transported in Standard Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The large dimensions and high weight of conventional excavation machines make them difficult to transport over long distances and limit their access to sites with restricted space, particularly in urban areas where civil engineering works need to minimize disruption.
Innovation Solution
The excavation machine is modular, allowing its components to be assembled on-site using quick fastening means and transported in standard containers, with a lifting module, displacement module, and control cabin designed to fit within ISO-compliant dimensions, enabling easier movement and assembly in confined spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the excavation machine is designed as a one-piece welded structure, then the machine achieves structural strength and stability, but the machine becomes difficult to transport over long distances and cannot access sites with limited space
Solution Approach 1:
The excavation machine is divided into multiple detachable modules including a lifting module, displacement module, and control cabin. Each module can be independently transported in standard containers and quickly assembled on-site using quick fastening means, resolving the contradiction between structural strength and transportability.
2Productivity
If the machine dimensions are increased to accommodate all components, then the machine has sufficient operational capacity, but the machine cannot be transported in standard containers or access confined sites
Solution Approach 1:
The machine is segmented into functional modules that can be transported separately in standard containers and assembled on-site, allowing sufficient operational capacity without requiring large transport dimensions.
Solution Approach 2:
The machine transitions from a static one-piece structure to a dynamic modular configuration that can be disassembled for transport and reassembled for operation, adapting its form to different operational and transport requirements.
3Power
If the machine weight is increased to provide sufficient lifting and excavation capability, then the machine achieves required operational performance, but the machine becomes expensive and difficult to transport
Solution Approach 1:
The machine is divided into modules that can be transported separately, reducing the weight burden on any single transport vehicle and lowering overall transportation costs while maintaining total operational capability through modular assembly.

AI summary
The machine (10) has a platform (12) provided with a rapid fixation unit e.g. pin fixation unit, and a lifting arm (18) for lifting a drilling tool (20). The lifting arm includes another rapid fixation unit cooperating with the former fixation unit. A hydraulic assembly (15) includes supplying and circulating units for supplying and circulating fluid in flexible conduits and a flexible tube. The tool, the platform, the arm and the assembly have dimensions for permitting each of the tool, the platform, the arm and the assembly to be placed in a container having standard dimensions.
