Furniture Drawer Railing Mount With Split Support Elements

Solution Overview

Problem

Existing solutions for attaching transverse and longitudinal railings to furniture drawers lack flexibility and ease of adaptation to optical design requirements, while also requiring complex assembly processes and tools.

Innovation Solution

A frame with a device comprising a first and second mounting element, where the first element is made of a stable material like sheet metal for strength and the second element, made of a less stable material like plastic, allows for easy adaptation to design requirements and assembly without additional tools, using holding elements for secure attachment and force transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single mounting element is used for attaching railings to the frame, then the device structure is simple, but it cannot meet diverse optical design requirements and lacks flexibility

Engineering Contradiction:

Improveadaptability to optical design requirementsVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting device is divided into two separate mounting elements: a first mounting element that protrudes upward from the fastening element and a second mounting element attached to the first. This segmentation allows each element to be optimized independently - the first element provides structural stability while the second element can be designed in various forms to meet different optical design requirements, thereby achieving versatility without excessive complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the mounting device are made from different materials with different properties. The first mounting element is made from a stable material (such as sheet metal) to provide structural strength, while the second mounting element can be made from various materials to achieve specific optical design characteristics. This local differentiation of material properties enables the device to meet diverse design requirements while maintaining overall structural integrity.

Inventive Principle:

Principle #3Local quality

2Reliability

If additional assembly tools are used for mounting the railing, then the attachment is more secure, but the assembly process becomes more complex and time-consuming

Engineering Contradiction:

Improvesecure mountingVSAvoidassembly process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The mounting elements are designed with self-aligning and self-securing features that eliminate the need for additional assembly tools. The first mounting element protrudes in a specific manner and the second mounting element is configured to attach directly to it, allowing the components to self-align and secure the railing in place through their own geometric features, thereby achieving reliable mounting while simplifying the assembly process.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Instead of using tools to force components together, the design inverts the approach by creating components that naturally guide and secure each other through their shapes. The mounting elements are designed so that the railing and frame components fit together through their inherent geometry, reversing the conventional approach of using external tools to achieve secure attachment.

Inventive Principle:

Principle #13The other way round (Inversion)

3Strength

If a stable material is used for the mounting element, then the structural strength is sufficient, but the adaptability to optical design requirements is reduced

Engineering Contradiction:

Improvestructural strengthVSAvoidadaptability to optical design requirements

Core Design Contradiction:

StrengthVSAdaptability or versatility

The mounting device is divided into two separate mounting elements: a first mounting element that protrudes upward from the fastening element and a second mounting element attached to the first.

AI summary

The invention is based on a device for attaching a transverse and/or longitudinal railing to a frame of a furniture drawer. The frame comprises a frame body and a fastening element for attaching a wall component to the frame body. In the area of a fastening side of the transverse and/or longitudinal railing, a carrier element is provided on the fastening element for arranging a drawer transverse wall. The essential aspect of the invention can be seen in the fact that a first and a second mounting element are present, with the first mounting element protruding upwards in the vertical direction over the fastening element. In addition, the first mounting member includes a first connection portion. The second mounting member is attached to the first connecting portion and adapted to mount the transom and/or longitudinal railing thereto.
