Wall Assembly Support Bar for Precise Furniture Plate Centering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assembling furniture bases using visible base-brackets require precise and time-consuming manual adjustment of wall plates to ensure identical interaxis between hooks and windows, often necessitating expert intervention due to small positioning errors, which leads to inefficiencies and increased costs.
Innovation Solution
A positioning and supporting group comprising a bar with threaded holes and plates with deep-drawn bushes, allowing for automatic and precise centring and fixing of plates to the wall, ensuring identical interaxis between hooks and windows, facilitating rapid and safe assembly of furniture bases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment of wall plates is used to ensure identical interaxis between hooks and windows, then positioning precision is improved, but assembly time and complexity increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-marking the correct positioning of plates on the wall through the bar before final assembly. The bar with marked positions serves as a guide, allowing workers to quickly transfer these pre-determined positions to the wall without requiring complex measurements or adjustments during assembly, thus resolving the contradiction between precision and time consumption
Solution Approach 2:
The bar acts as an intermediary tool that carries pre-calculated positioning information from the design stage to the assembly stage. It mediates between the need for precise interaxis positioning and the requirement for rapid assembly by providing physical guides and marks that eliminate the need for skilled manual measurement and adjustment
2Manufacturing precision
If expert intervention is used for plate positioning, then positioning accuracy is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The system enables self-service assembly by incorporating all necessary positioning information directly on the bar and plates. The marked positions and alignment features allow any worker to correctly position plates without requiring expert knowledge or intervention, thus improving ease of operation while maintaining positioning accuracy
Solution Approach 2:
All complex positioning calculations and measurements are performed in advance during bar manufacturing. The pre-marked positions transform a complex expert task into a simple replication operation that any worker can perform by following the pre-prepared guides, eliminating the need for expert intervention
3Manufacturing precision
If re-positioning of plates is performed to correct positioning errors, then positioning precision is improved, but assembly time and costs increase
Solution Approach 1:
The patent applies preliminary anti-action by preventing positioning errors before they occur. The bar with pre-marked positions and alignment features ensures that plates are correctly positioned from the first attempt, eliminating the need for re-positioning operations and their associated time losses and cost increases

AI summary
A positioning and supporting group for the wall assembly (P) of a piece of furniture (M) cantilever extending from the wall (P) itself, wherein a plurality of plates (20) is envisaged, destined for being fixed to said wall (P), by means of first fixing means (30), and a plurality of devices (21) fixed inside the shoulders (22) of said piece of furniture (M), and destined for being connected by means of hooks (23) to windows (24) of said plates (20) and wherein the interaxis "A" between the windows (24) of said plates (20) is substantially identical to the interaxis "A'" between said hooks (23). According to the invention, the positioning and supporting group comprises the combination of a plurality of said plates (20) with a positioning and/or fixing bar (25) of the plates (20) onto the bar (25) itself, said plates (20) and said bar (25) also being equipped with second reciprocal coupling means (28, 29), and/or fourth reciprocal coupling and centring means (32, 33), so that, at the moment of assembly of the piece of furniture (M), the above interaxes "A" and "A'" are substantially the same.
