Eccentric Disc Cabinet Fitting for Precise Wall Mount Adjustment
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
2Ease of manufacture
If sheet metal fittings are used, then manufacturing capability is improved, but weight and production cost increase
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
3Ease of operation
If multiple loose fitting parts are supplied, then assembly flexibility is improved, but risk of misalignment and assembly errors increases
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
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

Function Achieved in This Case
Facilitates quick and precise assembly of wall cabinets with reduced component complexity, lowering production costs and ensuring accurate alignment with fewer assembly steps, while maintaining adjustability.
Implementation Method 1
an eccentric disc (20) with an opening (23) which is designed in this way that the eccentric disc (20) can be pushed onto the shank (40) of a screw (40) with a screw head (40') mounted on a wall and that height and side adjustment of the mounting plate (11) relative to the screw (40) can be carried out by turning the eccentric disc (20)

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).
