Collapsible Chair and Stackable Stool Assembly for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for furniture designs that minimize storage footprint, incorporate minimalist aesthetics, and allow for customization without requiring extensive woodworking expertise or equipment, while also being suitable for smaller living spaces and environmentally friendly.
Innovation Solution
The design includes collapsible chairs with hinge joints that pivot between a compact and expanded configuration, stackable stool assemblies that combine to form a single base, and a system of joints with slots for assembling custom furniture pieces, allowing for easy construction and disassembly without needing advanced woodworking skills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If furniture is designed to be collapsible with hinge joints, then storage footprint is reduced, but structural complexity increases
Solution Approach 1:
The chair is divided into multiple rigid structural members (seat, backrest, legs, armrests) connected by hinge joints, allowing each component to be independently positioned and collapsed along with the main structure
Solution Approach 2:
The hinge joints enable the structural members to pivot dynamically between fixed angular positions, transitioning the chair from a stable expanded configuration to a collapsed planar configuration for storage
2Area of stationary object
If stools are designed to be stackable, then storage space efficiency improves, but manufacturing precision requirements increase
Solution Approach 1:
The stools are designed with asymmetric leg configurations and complementary seating surfaces that enable stable stacking in a specific orientation, with the first stool having legs positioned to receive the second stool and vice versa
Solution Approach 2:
The second stool is nested under the first stool in a face-to-face configuration, with the seats abutting parallel to each other and the legs interlocking to form a composite base structure
3Ease of manufacture
If furniture systems use standardized joints with slots, then ease of assembly improves, but structural strength decreases
Solution Approach 1:
The furniture system is segmented into reusable joints with slots and separate structural members, allowing components to be assembled and disassembled while maintaining connection integrity through the slot-and-member interface
Solution Approach 2:
The standardized joints with slots serve multiple functions: providing structural connection points, enabling adjustable positioning of members, and facilitating easy assembly and disassembly of the furniture system

AI summary
A chair including structural members having hinge joints at ends thereof pivotally coupling each of the members to one or more adjoining members. The chair is configured to be arranged in a collapsed configuration wherein all of the members are in the same plane and define a substantially planar shape, and configured to be arranged in an expanded configuration to define a seat, armrests, support legs, and leg braces of the chair. A stool assembly includes at least first and second stools configured to be stackable such that the seats of the stools abut face to face and in combination define a composite base. A system for constructing furniture includes multiple joints each having slots configured to receive and retain structural members and configured to be assembled with the structural members to form a piece of furniture with the multiple joints defining corners of the piece of furniture.
