Solution Overview

Problem

Existing furniture fittings for movable furniture parts are bulky due to separate adjustment means and have restricted accessibility of operating elements, making them inconvenient for use.

Innovation Solution

A furniture fitting with a carrier and spring device that allows for three-dimensional adjustment using three operable elements from a single side, eliminating the need for separate adjustment parts and enhancing accessibility by allowing all elements to be operated from the front side.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate adjustment means are arranged on different fitting parts, then three-dimensional adjustment capability is achieved, but the construction becomes bulky and complex

Engineering Contradiction:
Improvethree-dimensional adjustment capabilityVSAvoidconstruction bulkiness
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines all three adjustment means (first, second, and third adjustment means) into a single integrated adjusting device with three operating elements (first, second, and third operating elements) that are accessible from one side. This merging eliminates the need for separate adjustment parts while maintaining full three-dimensional adjustment capability, directly resolving the contradiction between adaptability and device complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If adjustment means are distributed on different fitting parts, then adjustment functionality is provided, but accessibility of operating elements is restricted

Engineering Contradiction:
Improveadjustment functionalityVSAvoidaccessibility of operating elements
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges all operating elements into a single adjusting device that is accessible from one side of the furniture fitting. The first, second, and third operating elements are all positioned such that they can be operated from the same side, eliminating the need to access different sides or locations for different adjustments, thus improving ease of operation while maintaining full adjustment functionality.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If multiple separate adjustment parts are used, then comprehensive adjustment control is achieved, but the fitting becomes less compact and more cumbersome

Engineering Contradiction:
Improveadjustment controlVSAvoidfitting compactness
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent integrates all adjustment mechanisms into a single compact adjusting device where the first, second, and third operating elements are housed together. This consolidation maintains comprehensive adjustment control for lateral, depth, and height directions while significantly reducing the overall volume and improving the compactness of the furniture fitting compared to using separate adjustment parts.

Inventive Principle:
Principle #5Merging (Combining)
