Solution Overview

Problem

Existing disposal vehicles face inefficiencies in collecting and transporting waste due to the need for manual cleaning of the filling chute and limited space for waste containers, which restricts the separation of different fractions and requires additional personnel and time.

Innovation Solution

A disposal vehicle design with a pivoting piston axis outside the pouring opening and receiving container, allowing for efficient material separation and compacting without manual cleaning, and enabling the use of interchangeable or swing-open receptacles for flexible container handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the drive shaft is located in the filling chute below the pouring opening to keep the vehicle length short, then the overall vehicle length is reduced, but material accumulates on the shaft requiring manual cleaning and additional personnel

Engineering Contradiction:
Improvevehicle lengthVSAvoidmanual cleaning requirement
Core Design Contradiction:
Length of moving objectVSEase of operation

Solution Approach 1:

The invention extracts the drive shaft from the material flow path by positioning it horizontally outside the pouring opening and receiving container. The piston axis is arranged perpendicular to the material flow direction, allowing the drive shaft to be located in a clean area away from waste material, eliminating the need for manual cleaning while maintaining compact vehicle dimensions

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the spatial arrangement by orienting the piston axis perpendicular to the material flow direction (horizontal arrangement outside the pouring opening) rather than parallel to it (vertical arrangement inside the chute). This dimensional repositioning removes the drive shaft from the contaminated zone while preserving the compact vehicle structure

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If a fixed receptacle is used below the oscillating piston to hold waste containers, then the piston can effectively convey material, but the space required for the piston limits the size and number of waste containers that can be accommodated

Engineering Contradiction:
Improvematerial conveyance efficiencyVSAvoidreceptacle volume
Core Design Contradiction:
ProductivityVSVolume of stationary object

Solution Approach 1:

The invention replaces the fixed receptacle with a swing-open receptacle that can be rotated between a closed position for material conveyance and an open position for emptying. This dynamic design allows the receptacle to swing open to the rear, providing ample space for large waste containers while maintaining effective material conveyance during the closed position

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention segments the receptacle into a movable swing-open section and a fixed section, allowing the swing section to rotate independently. This segmentation enables the receptacle to accommodate various container sizes by opening the swing section, while the fixed section maintains the structural integrity needed for effective piston-driven material conveyance

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the pouring opening is divided to separate different materials, then material separation is possible, but the shaft in the filling chute must be cleaned by hand involving additional personnel

Engineering Contradiction:
Improvematerial separation capabilityVSAvoidmanual cleaning requirement
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The invention extracts the drive shaft from the filling chute entirely by positioning it horizontally outside the pouring opening. This allows the pouring opening to be divided into multiple sections for different materials without the drive shaft interfering with material flow or requiring cleaning, as the shaft is located in a clean area away from all material paths

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention repositions the drive shaft from a vertical arrangement inside the filling chute to a horizontal arrangement outside the pouring opening. This dimensional change allows multiple pouring openings to be arranged vertically for different materials while the drive shaft remains in a clean area, eliminating manual cleaning requirements while maintaining full material separation capability

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The waste disposal vehicle (1) has a vehicle-mounted receptacle (2) for waste materials and recyclable materials. A feed device (3) is equipped with a single-or multi-part dumping aperture (7) for receiving of goods to be disposed. A piston is pivoted around an axis (11) for forwarding goods in the direction of the receptacle. The axis is held outside the dumping aperture, where a vertically continuing downward channel-like profile (12) is held at an outer side.
