Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual plastering method is used, then flexibility and adaptability to wall irregularities are improved, but working hours increase and productivity decreases
Solution Approach 1:
The system uses image capture devices to automatically detect wall irregularities and generates plastering paths without human intervention. The robot autonomously navigates and plasters based on detected features, making the system self-sufficient in adapting to wall variations.
Solution Approach 2:
The system captures images of the wall, processes them to detect irregularities, and uses this information to dynamically adjust the plastering path and parameters. This closed-loop feedback enables real-time adaptation to wall surface variations.
2Adaptability or versatility
If manual plastering method is used, then adaptability to irregular gaps is improved, but labor intensity increases
Solution Approach 1:
The patent replaces manual mechanical plastering with an automated robot system equipped with image capture and processing capabilities. The robot detects irregular gaps through imaging and automatically adjusts its plastering action, eliminating the need for skilled manual labor.
Solution Approach 2:
The image capture device and processing module act as intermediaries between the robot and the wall surface. They detect irregularities and translate them into controlled plastering motions, bridging the gap between detection and execution.
3Productivity
If automated spraying is used, then productivity is improved, but manufacturing precision of wall finish deteriorates
Solution Approach 1:
The system performs preliminary detection of wall irregularities and pre-calculates the plastering path before actual plastering begins. This advance preparation ensures that the robot is ready to precisely fill irregularities from the start, maintaining finish quality while enabling automated high-speed operation.
Solution Approach 2:
The system applies different plastering parameters to different regions of the wall based on detected irregularities. Areas with gaps or irregularities receive targeted plastering with adjusted parameters, while smooth areas receive standard treatment, ensuring uniform finish quality across the entire wall.
