Waste Collection Pipe Rotation Control via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste collection and treatment apparatuses face challenges in versatility and efficiency due to mechanical connections that restrict movement in the presence of obstacles, relying heavily on operator skill and attention for accurate and quick positioning of pipes.
Innovation Solution
An apparatus with a group of accessories featuring independent rotation axes for a suction pipe and a washing/fluidization pipe, controlled by a unit that can switch between synchronous and independent rotation modes, allowing for precise positioning regardless of obstacles through synchronized or independent pipe movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the trunk arm and hose reel are mechanically connected by means of a Cardan shaft, then the rotation of one accessory determines a corresponding rotation of the other accessory, but the stiffness of the mechanical connection makes the group of accessories operationally little versatile since it can actually be used only where there are no obstacles and/or hindrance to the rotation of one and/or both accessories
Solution Approach 1:
The patent divides the mechanically connected system into two independent rotatable accessories (trunk arm and hose reel), each capable of independent rotation about its own axis. This segmentation eliminates the constraint of the Cardan shaft mechanical connection while maintaining the reliability of individual component operation.
Solution Approach 2:
The patent introduces a control unit that dynamically manages the rotation of both accessories independently, allowing adaptive response to operational conditions and obstacles. The system transitions from a rigid mechanical connection to a flexible controlled system where each accessory can be positioned independently based on real-time requirements.
2Ease of operation
If the movement of the suction pipe and washing/fluidization pipe is controlled totally independently by an operator, then the operator can decide the movement order and speeds, but the accuracy and speed with which the two accessories are positioned, or ultimately, the intervention time and cost, only depend on the operator's skill and attention
Solution Approach 1:
The patent incorporates position sensors that provide feedback to the control unit about the angular position of each accessory. This feedback mechanism enables the control unit to automatically adjust movement speeds and positioning accuracy, reducing dependence on operator skill while minimizing intervention time.
Solution Approach 2:
The control unit automatically manages the positioning of both accessories based on sensor feedback, enabling the system to self-regulate its operation. This reduces the need for continuous operator intervention and minimizes positioning time while maintaining high accuracy.
3Manufacturing precision
If the trunk arm and hose reel are mechanically connected, then the rotation is synchronized, but the stiffness of the mechanical connection makes the group of accessories operationally little versatile since it can actually be used only where there are no obstacles
Solution Approach 1:
The patent separates the mechanically connected system into independently rotatable components, allowing each accessory to be positioned accurately without being constrained by the other. This segmentation maintains positioning precision while eliminating the versatility limitations imposed by rigid mechanical connections.
Solution Approach 2:
The patent replaces the mechanical Cardan shaft connection with an electronic control system that uses position sensors and a control unit to manage the rotation of both accessories. This substitution maintains synchronization and positioning accuracy while providing the flexibility to operate in constrained environments with obstacles.
