Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipe rehabilitation methods face challenges in accurately locating and exposing openings in pipes with oval or circular cross-sections, especially in bends, leading to potential leaks and costly repairs due to misalignment of the base unit relative to the horizontal plane.
Innovation Solution
Incorporating electronic inclination sensors on the base unit to detect its position relative to the horizontal plane, allowing for the determination of the absolute opening position and precise alignment of the exposure unit, thereby ensuring accurate material removal without damaging the inner lining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the base unit is moved in the longitudinal direction of a pipe with an oval or circular cross-section, then the base unit can be positioned at the opening location, but the base unit is not moved on a horizontally oriented flat surface causing misalignment
Solution Approach 1:
The patent replaces mechanical positioning systems with electronic inclination sensors to detect and compensate for deviations from the horizontal plane. Instead of relying on purely mechanical alignment, the system uses electronic sensing and computational correction to achieve accurate positioning of the base unit and exposure unit at opening locations in pipes.
Solution Approach 2:
The system changes the parameter being monitored from simple axial distance to a combination of axial distance and inclination angle. By measuring the inclination angle relative to the horizontal plane and using this parameter in calculations, the system compensates for pipe cross-section shape variations and achieves accurate horizontal positioning.
2Device complexity
If the exposure unit is brought into the predetermined position relative to the base unit without inclination detection, then the device structure is simpler, but the positioning of the exposure unit does not match the position of the opening
Solution Approach 1:
The patent introduces electronic inclination sensing to replace purely mechanical positioning methods. The inclination sensors and associated calculation system add electronic complexity but dramatically improve the manufacturing precision of opening exposure by ensuring accurate alignment between the exposure unit and the actual opening location.
3Productivity
If material removal is performed without accurate horizontal positioning, then the operation is faster, but leaks are created in the inner lining requiring costly repairs
Solution Approach 1:
The system performs preliminary detection of the base unit's inclination angle and calculates the corrected position before material removal begins. This preliminary action ensures that the exposure unit is accurately positioned at the opening location, preventing leaks and maintaining inner lining integrity while allowing the actual uncovering operation to proceed efficiently.
