Foldable High Chair With Sliding Height Adjustment for Table Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high chairs are inflexible in height and cannot be compactly folded, making them inconvenient to store and use under dining tables, as they require significant space and are difficult to adjust to match varying table heights.
Innovation Solution
A high chair design featuring a foldable support frame with rail and backup struts, sliding sleeves, and a positioning mechanism that allows for adjustable height and inclination, enabling the chair to be easily hidden under a dining table without the need for cumbersome folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the high chair is designed with fixed height structure, then the manufacturing simplicity is maintained, but the adaptability to different dining table heights is poor
Solution Approach 1:
The high chair employs a telescopic leg structure with multiple extendable segments that can be adjusted to different lengths, transforming the fixed height structure into a dynamic, adjustable one. This allows the chair to adapt to various dining table heights while maintaining structural integrity through locking mechanisms at each extension position.
Solution Approach 2:
The height of the high chair is modified by changing the length parameter of the leg structure through telescopic extension. By varying the extended length of the leg segments, the chair can accommodate different table heights, effectively using parameter adjustment to resolve the adaptability issue.
2Volume of moving object
If the high chair is designed with rigid frame structure, then the structural strength is maintained, but the compactness for storage is poor
Solution Approach 1:
The rigid frame structure is divided into multiple separable segments including telescopic legs and a detachable tray assembly. These segmented components can be disassembled and collapsed into a compact configuration for storage, while maintaining structural strength when assembled and locked into position during use.
Solution Approach 2:
The telescopic leg structure allows inner segments to be nested within outer segments when collapsed, significantly reducing the storage volume. The nested configuration maintains strength through interlocking features and locking mechanisms that secure the segments in their extended positions during use.
3Adaptability or versatility
If the high chair is designed with adjustable height mechanism, then the adaptability to different table heights is improved, but the ease of operation for frequent adjustment is reduced
Solution Approach 1:
The telescopic leg structure incorporates pre-positioned locking mechanisms at standard height intervals. Users can quickly adjust the height by simply releasing and re-engaging these pre-set locking positions, eliminating the need for complex adjustments or tools. The preliminary placement of locking mechanisms at common height levels facilitates rapid and easy operation.

AI summary
A high chair includes a foldable support frame, a chair, and a pair of positioning mechanism. The foldable support frame has a pair of rail struts and a pair of backup struts, the pair of backup struts being pivoted to the pair of rail struts and releasably locked in a use position by a spring-biased coupling sleeve. The chair has a pair of sliding sleeves being capable of sliding alone the pair of rail struts thereby hiding the chair under a dining table. The pair of positioning mechanism are mounted on the chair and associated with a pair of locking elements mounted in the sliding sleeves for releasably locking the sliding sleeves relative to the pair of rail struts, so as to adjust and fix the chair at a selected height.
