Construction Robot Clamp Jaws for Precise Vertical Block Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction robots for attaching tiles or bricks to vertical walls are complex, costly, and inefficient, particularly due to the use of suction cups that require smooth surfaces and multi-axis arms, which are not adaptable to size variations in building blocks.
Innovation Solution
A construction robot equipped with clamp jaws that grip building blocks by their edges, allowing for automatic attachment with glue, and a simplified system that compensates for size variations using a detection unit to adjust spacing between blocks, reducing complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If suction cups are used to hold tiles, then tiles can be attached to the robot arm, but the system requires smooth surfaces and becomes less versatile
Solution Approach 1:
The patent replaces the suction cup mechanism with a mechanical gripper system that uses clamp jaws to physically grip the edges of building blocks. This mechanical gripping system works reliably on both smooth and rough surfaces, eliminating the surface compatibility limitations of suction cups while maintaining secure holding during transport and attachment.
2Manufacturing precision
If multi-axes arms are used for tile attachment, then precise positioning is achieved, but system complexity and cost increase
Solution Approach 1:
The patent divides the positioning function into two independent parts: a simple transport mechanism that moves blocks to the attachment point, and a separate detection unit that measures block dimensions and compensates for variations. This segmentation allows using simpler, less complex mechanisms while maintaining precision through measurement and compensation rather than relying on complex multi-axis arm mechanisms.
Solution Approach 2:
The patent incorporates a detection unit that measures the actual dimensions of each building block and provides feedback to the control system. This feedback enables real-time compensation for size variations, allowing precise positioning even with simpler mechanical components, thereby reducing the need for complex multi-axes arms.
3Extent of automation
If standard robot systems are used, then automation is achieved, but cost and programming complexity increase for simple tasks
Solution Approach 1:
The patent implements a self-adjusting system where the detection unit automatically measures each building block's dimensions and the control system automatically compensates for variations. This self-service capability allows the simplified mechanical system to achieve precise attachment automation without requiring complex programming or high-end robotic components, making automation accessible for simpler tasks.
4Ease of operation
If suction cups are used, then tiles can be held during transport, but the system cannot handle rough surfaces
Solution Approach 1:
The patent replaces the suction cup mechanism with a mechanical gripper system that uses clamp jaws to physically grip the edges of building blocks. This mechanical gripping system works reliably on both smooth and rough surfaces, eliminating the surface compatibility limitations of suction cups while maintaining secure holding during transport and attachment.
