Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual detection method is used to detect blockages in tunnel, then detection can be performed, but it consumes large amount of detection time and labor
Solution Approach 1:
The robot performs self-propulsion and self-cleaning operations autonomously without human intervention. The drive assembly automatically drives the cleaning assembly and conduction assembly to rotate, and the pushing unit autonomously pushes the cleaning unit forward along the tunnel pipe interior, enabling the system to service itself
Solution Approach 2:
The patent replaces manual mechanical detection operations with an automated robotic system equipped with sensors and mechanical cleaning components. The intelligent robot substitutes human workers with an automated mechanism that can detect and clear blockages efficiently
2Measurement precision
If manual detection method is used when tunnel is blocked by silt, then detection can be attempted, but it is difficult to find specific blockage position due to water accumulation interference
Solution Approach 1:
The patent introduces detection components as intermediaries between the blockage and the control system. These sensors and detection devices act as mediators that can penetrate through water accumulation to detect and locate blockages accurately without direct human intervention in the water-filled environment
Solution Approach 2:
Manual visual inspection is replaced with automated detection components that can operate underwater or through water accumulation, substituting human sensory limitations with electronic sensing capabilities that are not affected by water interference
3Productivity
If manual way is used to clear blockages in tunnel, then blockage removal can be attempted, but it is difficult to clear blockages rapidly due to narrow working space and water interference
Solution Approach 1:
The cleaning assembly automatically performs blockage clearing operations without human assistance. The conduction assembly and cleaning assembly work autonomously to conduct and clean blocked parts of the tunnel pipe, eliminating the need for manual operations in narrow, water-filled spaces
Solution Approach 2:
The cleaning unit is divided into functional modules including drive assembly, cleaning assembly, and conduction assembly. This segmentation allows each component to perform its specific function efficiently - the drive assembly provides propulsion, the cleaning assembly performs scraping and clearing, and the conduction assembly guides the cleaning process
