Combination of a support device with a seat of a shelf for furniture shelves with optimised load transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shelf-supporting devices face challenges in providing adequate mechanical resistance while minimizing aesthetic impact and maintaining reduced dimensions, leading to inadequate load resistance due to concentrated stress on thinner sections of the shelf.
Innovation Solution
A shelf-supporting device with a main body having a solid front section and projecting elements that distribute load-bearing stress to thicker areas of the shelf, preventing contact with the housing seat's upper internal wall and utilizing a T-nut and cam mechanism for secure pin operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the shelf-supporting device is miniaturized to minimize aesthetic impact, then the device dimensions are reduced, but the mechanical resistance and load-bearing capacity deteriorate due to concentrated stress on thinner shelf sections
Solution Approach 1:
The device features a solid front section with increased thickness specifically positioned to transfer loads to thicker areas of the shelf. This localized structural enhancement allows the device to maintain reduced overall dimensions while providing sufficient mechanical resistance at the critical load-bearing location.
Solution Approach 2:
The invention addresses the load distribution problem by utilizing the depth dimension of the shelf, directing loads toward the thicker rear sections rather than relying solely on the front thickness. This dimensional approach allows miniaturization in the visible front area while maintaining strength through strategic load path design.
2Area of stationary object
If the device dimensions are reduced to minimize aesthetic impact, then the device becomes less visible, but the contact surface area with the shelf decreases leading to stress concentration
Solution Approach 1:
The solid front section is designed with locally enhanced properties (increased thickness and surface area) specifically at the load transfer interface. This localized quality enhancement distributes stress effectively without requiring the entire device to be larger, thus maintaining aesthetic appeal while reducing stress concentration.
3Volume of moving object
If the device is designed with reduced dimensions, then the aesthetic impact is minimized, but the load transfer capability to thicker shelf areas is compromised
Solution Approach 1:
The device is designed to transfer loads in the depth dimension of the shelf, directing forces toward the thicker rear sections. This three-dimensional load path design allows the device to maintain compact front dimensions for aesthetic purposes while ensuring reliable load transfer to structurally sound areas of the shelf.
Solution Approach 2:
The device is segmented into distinct functional zones: a solid front section for load transfer to thicker areas, and a rear section for housing engagement mechanisms. This segmentation allows each part to be optimized for its specific function, maintaining small overall dimensions while ensuring reliable load transfer capability.

AI summary
A shelf-supporting device suitable for creating a reversible connection of a shelf with an opposite shoulder of a piece of furniture includes a shelf bracket having a main body with a solid section in its front area, from a front surface of which a connection pin protrudes, and a profile shaped so that at least a portion of the upper surface of the main body does not come into contact with the upper internal wall of the seat, in which the main body is housed, and which is defined within the shelf when the shelf-supporting device is assembled into the shelf.
