Solution Overview

Problem

The existing methods for mounting wooden frames on iron brackets in furniture production are time-consuming and labor-intensive, resulting in elevated furniture heights that compromise user comfort.

Innovation Solution

A quick mounting holder structure featuring a crossbeam with perpendicular mounting pieces, fixing holes, and an elastic element, allowing for simple and rapid assembly by rotating the mounting support and using screws through oval mounting holes, which reduces the overall height of the furniture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the wooden frame is mounted on the iron bracket using traditional methods, then the structural strength is ensured, but the mounting process is time-consuming and labor-intensive

Engineering Contradiction:
Improvemounting speedVSAvoidassembly time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The mounting support is inverted during installation - it is turned over and the wooden frame is placed underneath it, rather than placing the frame on top of the bracket. This inversion enables quick mounting by allowing screws to be driven from below through the mounting holes, significantly reducing assembly time and labor intensity while maintaining structural strength

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of operation

If the traditional iron bracket structure is used, then the structural stability is maintained, but the furniture height becomes too high, decreasing user comfort

Engineering Contradiction:
Improveuser comfortVSAvoidfurniture height
Core Design Contradiction:
Ease of operationVSLength of stationary object

Solution Approach 1:

The mounting support extends downward below the seat plate level, utilizing the vertical dimension more effectively. This downward extension allows the wooden frame to be positioned lower, reducing the overall furniture height and improving user comfort while maintaining structural stability through the reinforced mounting holes and screw fixation

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The present invention discloses a quick mounting holder structure for sinking mechanical extension device of functional sofa, which includes a mounting support, a stretchable component, a backrest component, and a main body. The mounting support, the stretchable component, the backrest component are rotatably installed in the main body. The mounting support includes a crossbeam and at least one mounting piece. The crossbeam includes a side panel. At least one mounting piece is fixed on the side panel and is perpendicular to the side panel. At least one fixing hole and at least one mounting hole are provided on the at least mounting sheet. When the wooden frame is need to mount on the mounting support, it just needs to rotate the mounting support and put the wooden frame under the mounting support. The mounting support and wooden frame are fixed by an electric drill using a screw through the mounting hole. The operation is simple and quick. Further, at least one mounting piece is fixed on the side panel, lowering the mounting height, so that the height of the whole sofa and rocking chair is lowered. Thus, the comfortableness of the user is improved.
