Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing corner cupboard fittings do not allow for stepless height adjustment along the support column, limiting the flexibility in positioning the shelf.

Innovation Solution

A fitting with a clamping piece featuring adjustable clamping means, including movable clamping jaws, that can be adjusted between a clamping position for secure attachment and a release position for stepless height adjustment, enabling the fitting to be attached at any desired height along the support column.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If transverse bores in the support column are used for attachment, then the fitting can be attached at specific heights, but stepless height adjustment is not possible and the device complexity increases

Engineering Contradiction:

Improveheight adjustment flexibilityVSAvoidsupport column structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The clamping piece is designed with movable clamping jaws that can dynamically adjust to any position along the support column. The clamping jaws can be moved between a release position (for positioning) and a clamping position (for securing), enabling stepless height adjustment without requiring pre-defined attachment points in the support column.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The clamping piece performs both positioning and securing functions through its own structure. The clamping jaws themselves provide the attachment mechanism by gripping the support column surface, eliminating the need for separate attachment features like transverse bores in the support column.

Inventive Principle:

Principle #25Self-service

2Reliability

If the clamping jaws are designed to grip the support column, then secure attachment is achieved, but the insertion opening must be larger than the support column cross section

Engineering Contradiction:

Improveattachment securityVSAvoidinstallation convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The clamping jaws are designed to be movable relative to each other, allowing them to transition from an open state (for easy insertion onto the support column) to a closed gripping state (for secure attachment). This dynamic behavior resolves the contradiction between needing a large insertion opening and requiring secure grip.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The clamping jaws are positioned in an open state before attachment to facilitate easy insertion onto the support column. After positioning at the desired height, the clamping jaws are then closed to grip the support column securely, providing both easy installation and reliable attachment.

Inventive Principle:

Principle #10Preliminary action

AI summary

The fitting (12) has a shelf (22) partly projecting over a plane in an outer position, where the fitting is fastenable at a supporting column (39) by a fastening device. The fastening device has a clamping piece (34) with a clamping unit. The fastening device is adjustable between a clamping position and a release position, where the fitting is clamped at the supporting column in desired height position relative to the supporting column in the clamping position. A continuous vertical adjustment of the fitting along the supporting column in the release position is enabled.
