Wall-Cupboard Assembly System for Load Transfer to Rear Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The technical challenge lies in safely assembling wall-cupboards such that the entire weight is unloaded onto a rear load-bearing wall, while keeping the front wall virtually free of load, especially under abnormal loads like a person leaning against the cupboard, without compromising structural integrity or aesthetics.
Innovation Solution
The assembly system employs rigid connection elements between the rear load-bearing wall, front wall, and plates, comprising a tubular upright and omega-shaped brackets that can be adjusted in depth, ensuring that opposing forces are countered and the weight is distributed onto the rear wall, thereby releasing the front wall from load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a front wall is added to house connection elements, then aesthetic appearance and structural organization are improved, but the front wall becomes a load-bearing element which complicates the support system
Solution Approach 1:
The support system is segmented into two distinct functional parts: the front wall serves exclusively for aesthetic purposes and housing connection elements, while the rear wall serves exclusively for load-bearing functions. This segmentation allows each wall to be optimized for its specific purpose without compromising the other.
Solution Approach 2:
A rear wall is introduced as an intermediary load-bearing structure behind the front wall. This intermediary element transfers all loads from the wall-cupboard directly to the supporting structure, allowing the front wall to remain free of load while still providing aesthetic value and housing for connection elements.
2Ease of manufacture
If the front wall is used to house connection elements, then installation organization is improved, but the front wall must bear loads which reduces reliability of load transfer
Solution Approach 1:
The system separates the functions of housing connection elements and bearing loads into different walls. The front wall houses connection elements for easy installation, while the rear wall reliably transfers loads to the supporting structure.
Solution Approach 2:
The rear wall acts as an intermediary that receives loads from the wall-cupboard and transfers them directly to the supporting structure, ensuring reliable load transfer while allowing the front wall to focus on housing connection elements for easy installation.
3Stability of the object's composition
If the front wall bears loads, then structural integrity is maintained, but the aesthetic separation between walls is compromised
Solution Approach 1:
The support system is divided into two walls with distinct functions: the front wall provides aesthetic separation and houses connection elements, while the rear wall provides structural integrity by bearing and transferring loads. This segmentation allows both aesthetic and structural requirements to be satisfied simultaneously.
Solution Approach 2:
The rear wall serves as an intermediary load-bearing structure that maintains structural integrity without interfering with the aesthetic appearance of the front wall. It transfers loads behind the front wall, preserving the aesthetic separation while ensuring structural stability.
4Reliability
If rigid connection elements are used between rear wall and front wall, then load transfer reliability is improved, but device complexity increases
Solution Approach 1:
The load-bearing function is extracted from the front wall and transferred to the rear wall through rigid connection elements. This extraction allows the front wall to remain simple and aesthetic while the rear wall handles the complexity of load transfer through its rigid connections to the supporting structure.

AI summary
An assembly system, by means of wall-brackets (27) hooked to respective plates (25), of a wall-cupboard (22) 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 two walls (20,21) and said plates (25) which are assembled outside said second front wall (21).
