Solution Overview

Problem

Existing stacking bearing arrangements require extensive access for maintenance, leading to increased maintenance times and potential operational disruptions.

Innovation Solution

A modular stacking bearing arrangement design where the holding jack unit is integrated into a carrier element that can be easily accessed and replaced from within the container recording room, allowing for separate maintenance of each container absorption room without needing to expand the entire system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the retaining latch is integrated into the frame structure, then the system structure is simplified, but maintenance time increases due to extensive disassembly requirements

Engineering Contradiction:
Improvesystem structureVSAvoidmaintenance time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The retaining latch is segmented from the frame structure and integrated into a removable support element. This allows the latch to be maintained independently by removing only the support element, not the entire frame assembly, thus reducing maintenance time while keeping the overall system structure simple.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The retaining latch is extracted from the permanent frame structure and placed in a detachable support element. This extraction enables the latch to be removed and replaced quickly without disassembling the frame, resolving the contradiction between structural simplicity and maintenance accessibility.

Inventive Principle:
Principle #2Taking out (Extraction)

2Loss of time

If the retaining latch is made accessible for quick replacement, then maintenance time decreases, but the system requires more complex access mechanisms

Engineering Contradiction:
Improvemaintenance timeVSAvoidaccess mechanism
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The support element containing the retaining latch is segmented as a separate, self-contained unit. This segmentation allows the support element to be removed and replaced as a single component without requiring complex disassembly mechanisms, achieving quick maintenance with minimal added complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support element is designed to be easily removable and replaceable by maintenance personnel without requiring specialized tools or complex disassembly procedures. This self-service design enables quick maintenance while avoiding the need for elaborate access mechanisms.

Inventive Principle:
Principle #25Self-service

3Productivity

If one container receiving space is serviced separately, then operational downtime is reduced, but the system requires modular design complexity

Engineering Contradiction:
Improveoperational downtimeVSAvoidmodular design
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Each container receiving space is segmented with its own dedicated support element containing a retaining latch. This segmentation allows individual spaces to be serviced independently by removing only the specific support element needed, reducing operational downtime while the modular design remains manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support elements are designed as universal, interchangeable components that can be used in any container receiving space. This universality allows for quick replacement during maintenance while keeping the modular design systematic and not overly complex, as the same component design is reused throughout the system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This design significantly reduces maintenance times by enabling quick replacement of the holding jack unit and allows for efficient operation with minimal downtime, as only the affected container absorption space requires intervention.

AI summary

A stacking storage arrangement is described, comprising a frame (4, 5) with several container receiving compartments, each of which has an opening (19) at its lower end. A latch assembly is arranged at at least one opening (19), comprising at least one latch unit (10) with a retaining latch (11) that is movable between a locked position and a released position. The aim is to operate such a stacking storage arrangement economically. For this purpose, the retaining latch (11) is replaceable from the inside of the opening.
