Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing irrigation pipe manufacturing systems face reliability issues with detecting and drilling drippers at high rates due to inertia effects and vibrations in mechanical detection and drilling systems, which become unsuitable for rates above 800 drippers per minute.
Innovation Solution
A laser-based dripper detection system combined with a rotary drilling unit that rotates around an orthogonal axis, allowing for precise detection and drilling without contact and minimizing inertia, enabling detection and drilling rates up to 2000 drippers per minute.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mechanical detection and drilling systems are used, then detection and drilling can be performed, but inertia effects and vibrations become strong at high rates making the system unsuitable for rates above 800 drippers per minute
Solution Approach 1:
The patent replaces the mechanical detection system with a laser-based optical detection system. The laser beam detects dripper positions without physical contact, eliminating mechanical inertia and vibration problems that limited previous systems to 800 drippers per minute. This substitution enables reliable operation at rates up to 2000 drippers per minute.
2Speed
If mechanical detection systems operate at high speeds, then productivity increases, but vibrations and inertia effects increase causing the system to become unsuitable
Solution Approach 1:
The laser detection system replaces mechanical sensors and arms, using optical beams to detect dripper positions. This eliminates the harmful vibrations and inertia effects that occurred in mechanical systems at high speeds, allowing the pipe to move at higher velocities without compromising detection accuracy.
Solution Approach 2:
The laser beam acts as an intermediary between the detection system and the moving pipe. Instead of mechanical contact, the optical beam transfers information about dripper positions without being affected by the pipe's motion, vibrations, or inertia, enabling high-speed operation.
3Productivity
If the angular velocity of the eccentric of the drilling unit is continuously accelerating and decelerating, then drilling can be performed, but significant vibrations are generated making the system unsuitable for high rates
Solution Approach 1:
The patent replaces the mechanical drilling unit with a laser drilling system. The laser beam drills holes through the pipe wall without mechanical moving parts, eliminating the vibrations generated by accelerating and decelerating eccentrics. This enables high-rate drilling without the harmful vibrations that limited mechanical systems.
