Solution Overview
Problem
Prior small dining chairs for children are single-purpose and lack a friendly design, failing to accommodate various table heights and user convenience.
Innovation Solution
A multifunctional small dining chair with a foldable U-shaped support frame, height-adjustable seat, rotatable dining tray, and detachable armrests, allowing for flexible use with different table heights and easy access, featuring a novel structure with elastic clamping buttons and adjustable components for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the small dining chair is designed to be foldable and space-saving, then the storage space is reduced, but the chair becomes single-purpose and lacks user-friendly design features
Solution Approach 1:
The dining tray is designed with multiple functions: it can rotate 360 degrees to allow children to easily get in and out of the seat, it can be detached and cleaned separately, and it provides a dining surface. This multi-functional design resolves the contradiction by adding versatility without increasing storage space, as the tray folds together with the chair frame.
Solution Approach 2:
The dining tray is made rotatable relative to the armrests, allowing dynamic adjustment of its position. This enables the tray to adapt to different usage scenarios (dining, playing, getting in/out) while maintaining a compact folded state, thus resolving the contradiction between space-saving and versatility.
2Device complexity
If the dining tray is fixed to the armrests, then the structure is simple, but the tray cannot rotate to facilitate children getting in and out
Solution Approach 1:
The dining tray is designed to rotate relative to the armrests through a simple rotational connection. This dynamic feature allows the tray to move between fixed and rotated positions, enabling children to easily get in and out while maintaining relatively simple overall structure. The rotational mechanism adds minimal complexity while significantly improving ease of operation.
3Ease of manufacture
If the chair components are permanently fixed, then assembly is simple, but the chair cannot be folded for compact storage
Solution Approach 1:
The chair is divided into separable components (frame, seat, backrest, armrests with dining tray) connected by foldable joints. This segmentation allows each component to be independently manufactured and assembled, maintaining ease of manufacture while enabling the entire structure to fold compactly for storage. The modular design resolves the contradiction between assembly simplicity and space-saving folding capability.
