Solution Overview

Problem

Existing mounting solutions for wall cabinets are complex to assemble and costly to produce, with a high number of components leading to manufacturing inefficiencies and potential misalignment issues during installation.

Innovation Solution

A mounting system featuring an eccentric disc with a specifically designed opening that allows for easy assembly and adjustment by being pushed onto a screw with a screw head, enabling precise positioning with minimal components and simplified manufacturing through bending and stamping of metal sheets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a multi-part fitting with many individual components is used, then adjustment capability is improved, but assembly complexity and device complexity increase

Engineering Contradiction:
Improveadjustment capabilityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple adjustment functions (height adjustment, lateral adjustment, depth adjustment) into a single integrated eccentric mechanism. The eccentric disc integrates the adjustment functionality that would otherwise require multiple separate components, thereby reducing assembly complexity while maintaining full adjustment capability in three directions

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The eccentric disc serves multiple functions simultaneously: it enables height adjustment, lateral adjustment, and depth adjustment through a single component. This multi-functional design eliminates the need for multiple separate adjustment mechanisms, reducing the overall device complexity while preserving adaptability

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of manufacture

If sheet metal fittings are used, then manufacturing capability is improved, but weight and production cost increase

Engineering Contradiction:
Improvemanufacturing capabilityVSAvoidfitting weight
Core Design Contradiction:
Ease of manufactureVSWeight of moving object

Solution Approach 1:

The patent employs a composite construction where an aluminum profile (lightweight material) serves as the base structure, and plastic inserts are integrated into the eccentric disc and mounting plate. This composite approach reduces the overall weight compared to solid sheet metal construction while maintaining manufacturing feasibility and structural integrity

Inventive Principle:
Principle #40Composite materials

3Ease of operation

If multiple loose fitting parts are supplied, then assembly flexibility is improved, but risk of misalignment and assembly errors increases

Engineering Contradiction:
Improveassembly flexibilityVSAvoidalignment accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The eccentric mechanism integrates multiple adjustment functions into a single component that is supplied as one piece rather than multiple loose parts. This integration eliminates the risk of mismatched components while preserving full adjustment capability, as the eccentric disc inherently provides all necessary adjustment functions in a unified structure

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The eccentric disc is pre-designed with integrated adjustment features that ensure proper alignment and function when installed. The component is prepared in advance with all necessary geometric features (eccentric geometry, mounting holes, adjustment slots) precisely positioned, eliminating alignment errors that would arise from assembling multiple separate parts

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to a fitting (10), especially for mounting wall cupboards, comprising a mounting plate (11) having a cut-out section (14) into which an eccentric disk (20, 20', 20'') having an opening (23, 23') is inserted, a screw (40) extending through said opening (23, 23'). The fitting is characterized in that the opening (23, 23') on the eccentric disk (20, 20', 20'') is designed in such a manner that the eccentric disk (20, 20', 20'') can be placed on the shank of a wall-mounted screw (40, 40') having a screw head and the mounting plate (11) can be vertically and horizontally adjusted relative to the screw (40, 40') by rotating the eccentric disk (20, 20', 20''). The invention further relates to two angle fittings (101, 201), especially for mounting wall furniture, to a multi-part fitting (301), especially for wall mounting, and to a method for producing a multi-part fitting (301).
