Nested Ready-to-Assemble Seating to Reduce Package Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Ready-To-Assemble (RTA) furniture packaging methods do not adequately minimize cubic package size, leading to increased transportation and storage costs, and handling risks due to larger package sizes.
Innovation Solution
The design of RTA chairs and stools with a seat assembly and seat back assembly that nest within each other, allowing for compact disassembly and packaging, where the seat back assembly fits within the internal cavity of the seat assembly, and legs can be placed flat within the cavity or depression, reducing overall dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional RTA furniture packaging methods are used, then furniture can be shipped as component parts, but the cubic package size is not minimized, leading to increased transportation and storage costs
Solution Approach 1:
The patent applies nesting by placing the seat back assembly inside the seat assembly cavity, and positioning legs within the same cavity space. This nested arrangement allows multiple components to occupy the same three-dimensional space simultaneously, dramatically reducing the external package dimensions and minimizing transportation volume without compromising component integrity or assembly capability
2Volume of stationary object
If furniture is shipped as component parts, then freight cost per unit is reduced, but package size is larger than necessary, increasing warehouse space requirements
Solution Approach 1:
The nested configuration of seat back within seat assembly and legs within the same cavity creates a compact package that occupies minimal warehouse space. This nested doll approach allows the same furniture components to be stored in a fraction of the space required by conventional side-by-side or stacked packaging methods
3Object-affected harmful factors
If larger packages are used for RTA furniture, then components can be easily handled, but the risk of injury to individuals handling the items increases
Solution Approach 1:
The nested packaging creates a single compact unit that is easier and safer to handle than multiple separate components or large loose assemblies. The integrated nested structure reduces the number of separate pieces that must be maneuvered individually, thereby reducing handling complexity and injury risk while maintaining the RTA component separation benefits
