Wall Mounting Bar and Plates for Precise Furniture Assembly
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, leading to inefficiencies and the need for expert assemblers due to small positioning errors.
Innovation Solution
A positioning and supporting group comprising a bar with threaded holes and plates, where the plates are fixed to the wall using pegs, ensuring the interaxis between the hooks and windows is automatically identical, allowing rapid and secure 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 wall plates are pre-assembled on a support structure (bar or another plate) with precisely positioned holes that guarantee identical interaxis. This preliminary preparation of the positioning geometry eliminates the need for time-consuming manual adjustment during actual assembly, as the precision is built into the structure beforehand
Solution Approach 2:
A support structure (bar or intermediate plate) is introduced as a mediator between the wall and the wall plates. This intermediary component carries the pre-positioned holes and ensures that when wall plates are attached to it, they automatically achieve the correct identical interaxis positioning without requiring direct manual measurement and adjustment against the wall
2Manufacturing precision
If manual adjustment of wall plates is performed to correct positioning errors, then positioning precision is improved, but device complexity and expert intervention requirements increase
Solution Approach 1:
The support structure with pre-positioned holes performs the positioning function automatically. When wall plates are attached to the support structure, they self-align to the correct positions through the predetermined hole locations, eliminating the need for expert assemblers to perform complex measurement and adjustment operations
Solution Approach 2:
The correct positioning geometry is pre-established in the support structure during manufacturing. This preliminary action embeds the positioning intelligence into the structure itself, so that during assembly, the system automatically guides the wall plates to their correct positions without requiring complex adjustment procedures or expert knowledge
3Adaptability or versatility
If multiple adjacent bases are assembled with manually positioned plates, then assembly flexibility is maintained, but cumulative positioning errors make assembly impossible
Solution Approach 1:
The support structure pre-establishes the correct interaxis positioning for all wall plates before assembly begins. This preliminary positioning ensures that even when multiple adjacent bases are assembled, each base aligns perfectly with its corresponding wall plate, preventing cumulative errors from occurring
Solution Approach 2:
The support structure acts as a mediator that transfers the precise positioning geometry to all wall plates simultaneously. By attaching all wall plates to this single reference structure with pre-positioned holes, the system ensures consistent identical interaxis across multiple bases, eliminating the cumulative error problem that occurs with independent manual positioning

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