Child's high chair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing children's high chairs have complex constructions and limited adjustability, making them unsafe and difficult to use effectively.
Innovation Solution
A children's high chair design featuring a seat element held on two side support arms with two-hand safety controls, pivotally mounted with a tilt lock, and a gas pressure spring system for height and inclination adjustment, along with a detachable table and adjustable footrest, ensuring safety and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the foot part is composed of numerous individual elements, then the adjustability is improved, but the device complexity increases
Solution Approach 1:
The foot part is divided into a telescopic first footrest element and a second footrest element that can be independently adjusted and locked at different positions, allowing segmented adaptation to different child sizes and needs while maintaining manageable complexity through modular design
Solution Approach 2:
The footrest elements feature telescopic and adjustable mechanisms with lockable positions, transitioning from static to dynamic structure that can adapt to different usage requirements while maintaining stability when locked
2Ease of operation
If the seat element is made rotatable and lockable, then the ease of operation is improved, but the reliability may be compromised
Solution Approach 1:
A two-hand safety control mechanism requires simultaneous operation of both control elements to release the locking mechanism, preventing accidental or unauthorized rotation by children while maintaining easy intentional adjustment by adults
Solution Approach 2:
The control elements are positioned and designed to require deliberate two-handed operation, preparing the safety mechanism in advance to prevent unintended activation during normal use
3Adaptability or versatility
If a telescopic safety support is added, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The safety support is designed as a telescopic mechanism with adjustable length that can be independently modified to match different table heights and positions, providing adaptability through segmented adjustment rather than multiple discrete components
Solution Approach 2:
The telescopic safety support serves multiple functions: providing safety guidance, preventing excessive pulling forces, and adapting to different table configurations, reducing the need for separate components for each function
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides a simple, safe, and highly adjustable high chair that prevents accidental operation by children, allowing for easy height and inclination adjustments while ensuring the table remains horizontal across various angles.

AI summary
The highchair (1) has a base part (2), and a seating unit (4) that is held on the base part. A single and/or perpendicularly arranged, length-changeable gas-pressure spring (6) for supporting and height adjustment of the seating unit is provided between the base part and the seating unit. The base part has a ring part (8) that includes a central transverse unit, at which the seating unit is held, where the transverse unit is designed as a plastic shaped part.
