Drawer Front Attachment with Lateral Pivot Fitting

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing drawer attachment systems require significant space for inserting attachment members, which can impede the fitting process when multiple drawers are stacked, and often necessitate dismantling of the drawer components for installation.

Innovation Solution

The attachment element is introduced into a recess in the fitment body and can pivot laterally, eliminating the need for additional height space, allowing for independent fitting and removal without tools, and enabling modular connection and disconnection without affecting the drawer side walls or rear wall.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If attachment elements are introduced using conventional methods, then the attachment can be secured to the drawer, but a large amount of space is required for introducing the attachment members which impedes the fitting process when multiple drawers are stacked

Engineering Contradiction:

Improveease of fitting attachment elementVSAvoidspace required for introducing attachment member

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The attachment element is introduced into the recess from a lateral direction rather than from above, changing the dimension of insertion. This allows the attachment element to be fitted without requiring vertical space, enabling stacked drawers to be fitted independently without interference from adjacent drawers.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the drawer components are assembled into a common structural unit, then the drawer structure is stabilized, but the attachment element cannot be easily added or removed without dismantling the drawer

Engineering Contradiction:

Improveability to add or remove attachment elementVSAvoidstructural integrity of drawer

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The drawer system is segmented into three independent components: the drawer body, the fitment body, and the attachment element. The fitment body is pre-installed on the drawer, and the attachment element can be independently added or removed from the fitment body without affecting the drawer's structural integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fitment body acts as an intermediary component between the drawer and the attachment element. It provides a stable mounting base on the drawer and a recess for the attachment element, enabling easy attachment and detachment while maintaining drawer stability.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the attachment element is made movable after insertion, then the attachment can be adjusted and repositioned, but the mechanism for movement increases device complexity

Engineering Contradiction:

Improveadjustability of attachment elementVSAvoidcomplexity of attachment mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The attachment element is designed to be movable within the recess of the fitment body, allowing lateral and rotational adjustments. This dynamic capability enables the attachment element to be repositioned to different locations on the drawer front panel without requiring complex adjustment mechanisms.

Inventive Principle:

Principle #15Dynamics

AI summary

A drawer includes a front panel, a lateral drawer wall, and an attachment element arranged at least partially over the drawer lateral wall. The attachment element is intended to be fastened to the front panel by a fitting body separate from the drawer lateral wall, and the fitting body includes at least one fixing point for fixing to the front panel and a recess for receiving the attachment element. After completed mounting of the fitting body on the front panel, the attachment element can be brought into the recess of the fitting body, and the attachment element can be brought into the recess of the fitting body and can subsequently be pivoted about a notional axis running substantially vertically in the mounting position.
