Solution Overview

Problem

Existing methods for loading piece goods, particularly fragile postal parcels, into transport boxes are inefficient and prone to damage due to the risk of parcels falling and causing downtime, as conveyor belts often require stopping and result in high drop heights, leading to damage and long loading times.

Innovation Solution

A method involving a transport box with a loading opening and a conveyor device where the transport box is tilted to allow piece goods to fall into a receiving pocket, preventing them from getting stuck in the segmented locking device and allowing for a controlled, gravity-assisted loading process, minimizing drop height and preventing damage, while maintaining continuous loading.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the conveyor belt is pulled back to stack further layers of mailbags, then more layers can be loaded, but mailbags fall down and piece goods are damaged

Engineering Contradiction:
Improveloading capacityVSAvoidpiece goods safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The transport box is pre-positioned at an inclined angle before loading begins. This preliminary positioning creates a gravity-driven slope that prevents piece goods from falling when the conveyor belt retracts, allowing continuous operation without stopping to prevent damage.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The inclination angle of the transport box is changed from horizontal to a specific angled position during loading. This parameter change enables gravity to control the movement of piece goods, allowing them to slide smoothly to the rear when the conveyor belt moves back, preventing falls and damage while maintaining loading productivity.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the conveyor belt stops to allow controlled unloading, then piece goods can be safely unloaded, but loading time increases

Engineering Contradiction:
Improvecontrolled unloadingVSAvoidloading time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The conveyor belt operates continuously without stopping during the loading process. The inclined position of the transport box ensures that piece goods are safely guided to the rear as the conveyor belt continuously feeds them, eliminating downtime while maintaining controlled unloading through gravity.

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If piece goods are dropped from high conveyor belt, then loading speed increases, but piece goods are damaged

Engineering Contradiction:
Improveloading speedVSAvoidpiece goods integrity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The inclined transport box creates a gradual slope that reduces the effective drop height. Piece goods slide down the incline rather than falling vertically, converting potential energy into controlled kinetic energy along the slope, which prevents damage while maintaining loading speed.

Inventive Principle:
Principle #12Equipotentiality

Solution Approach 2:

The gravity that would cause harmful falls is converted into a beneficial force by positioning the transport box at an incline. The same gravitational force that could damage piece goods during vertical drops is harnessed to guide them smoothly along the inclined surface to the rear of the box.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

4Ease of operation

If the segmented locking device is positioned close to the loading opening, then it can effectively close the opening, but piece goods get stuck in the segments

Engineering Contradiction:
Improveloading opening closureVSAvoidloading continuity
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The segmented locking device is extracted from the main loading area and positioned in a receiving pocket at the rear of the transport box. This separation prevents piece goods from interfering with the locking mechanism while the inclined surface continues to guide goods effectively to the rear where the locking device operates independently.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The method involves providing a transport box (12) which has a single-loading opening (14) for loading of cargo (18). A conveyor (16), particularly conveyor belt, is arranged relative to the loading opening. The cargo is over-turned from the conveyor over a drop height (a) within the transport box. An independent claim is also included for a single-loading system for use in a loading arrangement for loading of cargo, particularly postal packages.
