Modular Excavator Quick-Connect Assembly for Disaster Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction machinery is limited in its ability to quickly reach disaster sites due to damage of transport facilities and inadequate air transport capacity, delaying emergency rescue operations.
Innovation Solution
A modular excavator composed of detachable assembly modules, each weighing less than 2.8 tons, connected by a quick connection structure with guide positioning and locking mechanisms, allowing for rapid assembly and transport to disaster sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional construction machinery is used, then the excavator has sufficient power and functionality, but it cannot be transported to remote or disaster-stricken areas due to weight and transport limitations
Solution Approach 1:
The excavator is divided into multiple independent assembly modules (base module, track beam assembly module, track module, clewing drive module, power assembly module, counterweight module, cab module, fuel tank module, boom assembly module, bucket arm assembly module, and work tool module), each weighing less than 2.8 tons. This segmentation enables the excavator to be transported by various means including air transport to remote areas, while maintaining full functionality when assembled.
2Productivity
If the excavator is transported to disaster sites, then rescue operations can be conducted, but assembly and disassembly time is excessive, delaying emergency response
Solution Approach 1:
The quick connection structure includes pre-designed guide positioning structures and locking structures that enable rapid assembly. The guide positioning structure with guide elements and positioning features allows modules to be quickly aligned and connected, while the locking structure provides immediate secure fixation, significantly reducing assembly and disassembly time for emergency response.
3Adaptability or versatility
If modular design is implemented, then transportability is improved, but the connection structure becomes more complex
Solution Approach 1:
The quick connection structure is segmented into distinct functional components: guide positioning structure (including guide elements and positioning features) and locking structure. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity. The guide positioning structure ensures accurate alignment, and the locking structure provides secure connection, achieving reliable modular assembly without excessive complexity.
