Modular Collapsible Chair with Nested Components for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional high chairs for children are bulky and have a large footprint, making them difficult to transport and store, even when foldable, as they remain elongated and inconvenient to carry.
Innovation Solution
A modular chair system with a seat and tray portion that can be compacted by pivoting arms and backrests, and telescoping legs, allowing the chair to be disassembled and reconfigured to minimize its footprint for easier portability and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional high chairs are made foldable, then portability is improved, but the chair remains elongated and occupies large storage space
Solution Approach 1:
The chair components are designed to nest within each other when collapsed. The seat nests within the backrest, and the tray nests within the seat, creating a compact bundled configuration that minimizes storage volume while maintaining portability
Solution Approach 2:
The chair is divided into separable modular components including a backrest, seat, tray, and leg assemblies. These segments can be independently collapsed and nested within each other, allowing the chair to transition from an extended usable configuration to a compact stored configuration
2Area of stationary object
If the chair is designed with multiple movable components for compacting, then footprint is minimized, but device complexity increases
Solution Approach 1:
The chair employs dynamic components including pivot joints for the backrest and seat, telescoping leg mechanisms, and movable tray supports. These dynamic elements allow the chair to transition between extended and compact states, minimizing footprint while the modular design keeps the overall structure manageable
3Volume of moving object
If the chair is made fully collapsible for storage, then storage efficiency is improved, but assembly and disassembly time increases
Solution Approach 1:
The chair components are pre-configured with aligned connection points, matching interfaces, and predetermined collapse sequences. The modular segments are designed to nest in specific orientations, allowing users to quickly assemble and disassemble the chair by following the pre-established configuration paths without complex alignment procedures
