Solution Overview

Problem

Existing transport solutions for furniture fittings with pull-out guides fail to securely position and protect the drawer slides during transport, often leading to damage and increased handling difficulties due to unstable structures.

Innovation Solution

A transport container with upwardly protruding pins in each compartment to secure pull-out guides, allowing for precise positioning and easy insertion/removal, along with a stackable design and magnetic support for enhanced security and compact transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pull-out guides are stored in open compartments without securing elements, then handling and insertion are simple, but the guides shift and tip during transport causing damage

Engineering Contradiction:
Improvepositioning stabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The transport container is divided into multiple compartments, each equipped with its own securing pin. This segmentation allows each pull-out guide to be independently secured without requiring a complex overall structure, resolving the contradiction between positioning stability and structural simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pin is designed to be automatically inserted into the pull-out guide's opening when the guide is placed in the compartment, and the guide itself serves as its own securing mechanism through the interaction with the pin. This self-service approach provides reliable positioning without requiring additional complex securing mechanisms.

Inventive Principle:
Principle #25Self-service

2Object-affected harmful factors

If stable structures are provided to arrange visible sides at a distance from packaging, then damage to sensitive surfaces is prevented, but transport volume increases and handling becomes difficult

Engineering Contradiction:
Improvesurface damage protectionVSAvoidtransport volume
Core Design Contradiction:
Object-affected harmful factorsVSVolume of stationary object

Solution Approach 1:

Instead of providing extensive three-dimensional protective structures around the pull-out guides, the invention uses pins extending in the vertical dimension to secure the guides. This dimensional approach provides protection against surface damage while maintaining compact transport volume and easy handling.

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

3Ease of operation

If the transport container is designed for precise positioning of pull-out guides, then handling is simplified, but the container structure becomes more complex

Engineering Contradiction:
Improvehandling easeVSAvoidcontainer structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The positioning function is extracted from the overall container structure and implemented through simple, discrete pins that can be easily manufactured and integrated. This extraction allows precise positioning without requiring the entire container structure to be complex.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The container (1) has an elongated cabin (5) in which an elongated object is inserted and removed. A protruding top pin (6) is inserted into an opening of the elongated object for a position securing unit. The elongated cabin is spaced by a partition (7). Side walls (3, 4) of the container are formed in a sliding manner, where the container is made of plastic. A protruding top bar (8) is formed at a base of the container. A guide rail is mounted at a furniture body. A strip-shaped groove is formed on the guide rail.
