Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated construction methods, such as gantry robots, are costly, inflexible, and unsuitable for high-rise buildings due to their size and space requirements, and they still necessitate human intervention, posing safety and economic challenges.
Innovation Solution
A mobile structure assembling robot with an elongated telescopic bridge, beam gripping mechanisms, a beam lifting assembly, and a welding arm, capable of navigating and assembling structural beams within a building by gripping and welding beams in place, eliminating the need for external rails and allowing for adaptable sizing based on the building dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If gantry robots are used for automated construction, then automation level and productivity are improved, but device complexity, cost, and space requirements increase significantly
Solution Approach 1:
The construction robot is divided into multiple independent modules: telescopic bridge mechanism, beam gripping mechanisms, beam lifting assembly, and welding arm. Each module performs a specific function and can operate semi-independently, reducing overall system complexity while maintaining high automation capability
Solution Approach 2:
The robot integrates multiple functions into a single mobile platform: it can grip beams, lift beams, position beams, and perform welding operations. This multi-functionality eliminates the need for separate specialized equipment, reducing device complexity while achieving high automation
2Extent of automation
If gantry robots are used for automated construction, then automation level is improved, but cost increases significantly
Solution Approach 1:
The mobile robot performs multiple construction tasks (beam gripping, lifting, positioning, and welding) in one integrated system, eliminating the need for separate expensive specialized equipment. This multi-functionality significantly reduces overall project cost while maintaining high automation
Solution Approach 2:
The telescopic bridge mechanism allows the robot to dynamically adjust its span length to match different building dimensions. This adaptability eliminates the need for custom-built expensive gantry systems for each project, reducing costs while maintaining automation
3Productivity
If gantry robots are used for automated construction, then productivity is improved, but adaptability to different building sizes decreases
Solution Approach 1:
The telescopic bridge mechanism enables the robot to dynamically adjust its span length to match different building dimensions. The bridge can extend or retract to accommodate various distances between structural beams, making the same robot adaptable to different building sizes while maintaining high construction speed
Solution Approach 2:
The robot changes its physical parameters (bridge length, gripping force, lifting height) to adapt to different building configurations. This parameter adjustability allows the robot to work efficiently on buildings of varying sizes without sacrificing productivity
4Ease of manufacture
If conventional welding methods are used, then manufacturing simplicity is maintained, but harmful factors to workers increase
Solution Approach 1:
The robot replaces human workers with automated welding end-effectors that perform welding operations. This substitution eliminates workers from hazardous environments while maintaining relatively simple welding processes through automated control
Solution Approach 2:
The robot autonomously performs welding operations without human intervention in the hazardous zone. The automated system handles the dangerous tasks itself, protecting workers from exposure to welding fumes, high temperatures, and potential electrocution while keeping the welding process itself relatively simple

AI summary
A structure assembling robot may include an elongated telescopic bridge, at least one beam gripping mechanism mounted on the elongated telescopic bridge, a beam lifting assembly, a clamp rotatably mounted on the elongated telescoping bridge, and at least one welding arm assembly. The beam gripping mechanism may be configured to be mounted around a structural beam and allow for structure assembling robot to move on the structural beam. The beam lifting assembly configured to lift a structural beam to the position of the structure assembling robot. The at least one welding arm assembly may be configured to weld and mount the lifted structural beam to a building structure while the clamp fixes the lifted structural beam in a desired position and a desired orientation relative to the building structure.
