Solution Overview

Problem

The technical challenge lies in safely assembling wall-cupboards to a supporting structure consisting of two walls, where the rear load-bearing wall must bear the entire weight of the cupboards while keeping the front wall virtually load-free, especially under aesthetic and functional demands in kitchen designs.

Innovation Solution

The assembly system employs rigid connection elements housed in the interspace between the rear load-bearing wall and plates, which are assembled outside the front wall, allowing the front wall to remain unaffected by the cupboards' load through a combination of tubular uprights and U-shaped brackets or profiled sections, transmitting forces directly to the rear wall.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If wall-cupboards are assembled to a supporting structure with two walls (rear load-bearing wall and front wall), then aesthetic appeal and functional design are improved, but the structural reliability deteriorates because the front wall may be subjected to loads it cannot bear

Engineering Contradiction:
Improveaesthetic appealVSAvoidstructural reliability
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The invention extracts the load-bearing function from the front wall by introducing separate rigid connection elements that bypass the front wall entirely. These connection elements are housed in the interspace between the rear wall and plates, creating a direct load path from the wall-cupboard to the rear load-bearing wall, thus removing the front wall from the structural load path while preserving its aesthetic function

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention introduces rigid connection elements as intermediary components that mediate between the wall-cupboard and the rear load-bearing wall. These intermediaries (comprising tubular uprights and U-shaped brackets or profiled sections) transmit forces directly to the rear wall without involving the front wall in load bearing, thus resolving the contradiction between aesthetic design and structural reliability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the front wall is used as part of the supporting structure, then device complexity is reduced, but the front wall experiences stress and potential tilting under load

Engineering Contradiction:
Improvesupporting structure complexityVSAvoidfront wall strength
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The invention segments the supporting structure into distinct functional components: the front wall retains its aesthetic and protective function, while the rigid connection elements housed in the interspace handle all load-bearing functions. This segmentation allows each component to perform its specialized function without compromise, preventing the front wall from experiencing stress or tilting

Inventive Principle:
Principle #1Segmentation

3Reliability

If rigid connection elements are housed inside the interspace between the rear wall and plates, then the front wall remains load-free, but the assembly complexity increases

Engineering Contradiction:
Improveload distributionVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention applies the nesting principle by housing the rigid connection elements (tubular uprights and brackets) within the interspace between the rear wall and the plates. This nested arrangement allows the connection elements to be concealed within the existing structural void, ensuring the front wall remains load-free while minimizing the visual and spatial impact of the added complexity

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

An assembly system, by means of wall-brackets (27, 28) hooked to respective plates (25, 26), of a wall- cupboard (22, 23) to a supporting structure consisting of two walls (20, 21): a first rear load-bearing wall (20) and a second front wall (21), interspaced with respect to said first wall (20) so as to form an interspace (24), characterized in that rigid connection elements (C) are housed in said interspace (24) between said first rear load-bearing wall (20) and said plates (25, 26) which are assembled outside said second front wall (21).
