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

VSEngineering 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

Engineering Contradiction:
Improvemechanical connection reliabilityVSAvoidoperational versatility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improveoperator control flexibilityVSAvoidintervention time
Core Design Contradiction:
Ease of operationVSLoss of time

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.

Inventive Principle:
Principle #23Feedback

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.

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improvepositioning accuracyVSAvoidoperational versatility
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
