Solution Overview

Problem

Existing sorting and order-picking systems face challenges in maximizing storage capacity and efficient retrofitting in existing plants, with limitations in simultaneous storage and transportation of goods due to mechanical barriers and variable chute angles.

Innovation Solution

A terminal device design that allows for adjustable and pivotable transport devices, enabling multi-layer storage by lowering the feed side to create additional storage space, with a backwater wall to prevent goods from slipping, and a drive unit for precise control, allowing for efficient storage and retrieval of goods without costly conversions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the transport device is lowered to create storage space, then storage capacity is increased, but the risk of goods damage increases due to sliding

Engineering Contradiction:
Improvestorage capacityVSAvoidgoods damage
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

A backwater wall is introduced as an intermediary element to prevent goods from sliding when the transport device is lowered. The wall acts as a barrier between the goods and the downward movement, allowing the device to be lowered for storage while protecting the goods from damage

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The backwater wall is positioned beforehand to cushion or prevent the harmful effect of goods sliding during the lowering process. By having the protective structure in place before the lowering occurs, the system prevents damage rather than reacting to it after the fact

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Quantity of substance

If the feed side is lowered to maximize storage space, then storage capacity is increased, but goods may slip down against the conveying direction

Engineering Contradiction:
Improvestorage capacityVSAvoidgoods slipping
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The backwater wall serves as an intermediary structure that blocks goods from slipping down against the conveying direction when the feed side is lowered. It mediates between the lowered feed side and the goods, preventing harmful movement while allowing storage

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If mechanical barriers are used to prevent goods from overloading ramps, then storage organization is improved, but storage capacity is limited

Engineering Contradiction:
Improvestorage organizationVSAvoidstorage capacity
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The transport device is made dynamically movable between different height positions rather than being fixed. By lowering the feed side to a lower position, the system creates additional storage space while using the backwater wall to maintain organization and prevent overload, thus increasing capacity without sacrificing operational control

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to an end-point device (10) for a sorting and picking system (20), wherein the end-point device (10) has at least one conveying apparatus (11, 11a, 11b) having a feed side (12) and a discharge side (13), at the feed side (12) of which goods (40) of a feed-side conveying means (21) can be fed, which goods can be stored on the conveying apparatus (11, 11a, 11b) until the end of a loading cycle. The problem addressed by the invention is that of providing an end-point device (10) that can be integrated into existing sorting and picking systems without complex conversion measures and that additionally enables the largest possible storage capacity for goods (40). According to the invention, the problem is solved by means of an end-point device (10) in the case of which at least the feed side (12) of the conveying apparatus (11, 11a, 11b) is lowered from an upper height position ((Ho) to a lower height position (Hu) during the loading cycle.
