Solution Overview

Problem

Conventional chairs with unfoldable supports can only be stacked either horizontally or vertically, limiting storage options and posing difficulties when storing in different spaces.

Innovation Solution

A chair assembly with a frame, turnable seat, backrest, and armrests, featuring an assembling shaft and positioning rod for seat rotation, and hooks and slots for alignment, allowing for both horizontal and vertical stacking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If chairs are designed with unfoldable supports for stability, then chair stability is improved, but storage flexibility deteriorates because chairs can only be stacked in one orientation

Engineering Contradiction:

Improvechair stabilityVSAvoidstorage flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The seat is designed to be rotatable relative to the frame through 90 degrees, allowing it to switch between a horizontal position (for stable sitting) and a vertical position (for compact stacking). This dynamic adjustment enables the chair to adapt between stability and storage flexibility as needed

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The invention adds a rotational dimension to the seat, allowing it to move from a horizontal plane to a vertical plane. This dimensional change enables the chair to be stacked both horizontally and vertically, resolving the contradiction between stability and storage flexibility

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A chair assembly capable of being stacked vertically and horizontally includes a frame assembled with a turnable seat, a backrest, and armrests; wherein the frame is comprised of two frontal supports and two rear supports; an assembling shaft is horizontally disposed within the frame for holding and allowing the seat to be turned, a positioning rod disposed parallel to the assembling shaft for allowing the seat to be turned upward or downward and keeping the seat upturned or downturned. The assembly and combination of the frame, the backrest, the armrests, and the turnable seat causes that the resulted chair is stacked both horizontally and vertically. Moreover, the disposition of hooks and slots at both sides of the frame further allow the chairs to be aligned and connected together in an orderly manner.
