Highchair footrest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional highchairs lack an adjustable footrest mechanism that can accommodate children of varying heights and developmental stages, limiting their adaptability and comfort.
Innovation Solution
An infant highchair with a footrest that features two rotators configured to rotate between multiple positions, allowing for adjustable height settings, and a locking mechanism to secure the footrest in desired positions, ensuring proper foot support for children of different heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed footrest is used in conventional highchairs, then the structure is simple, but it cannot accommodate children of varying heights and developmental stages
Solution Approach 1:
The footrest is designed with rotators that allow it to rotate between multiple positions (at least 180 degrees), transitioning from a fixed structure to a dynamic, adjustable one. This enables the footrest to adapt to different height requirements while maintaining structural integrity through controlled rotational movement.
Solution Approach 2:
The footrest mechanism is divided into separable components: the footrest platform, rotators for rotation, and locking mechanisms for position fixation. This segmentation allows independent optimization of each component while achieving overall adaptability through their coordinated operation.
2Adaptability or versatility
If an adjustable footrest mechanism is added to accommodate varying heights, then adaptability is improved, but the device complexity increases
Solution Approach 1:
Multiple functions are merged into integrated components: the rotators simultaneously provide rotation capability and structural support, while the locking mechanisms combine position fixation with ease of operation through spring-loaded buttons. This merging reduces the number of separate parts needed.
Solution Approach 2:
The footrest mechanism is designed to perform multiple functions: supporting feet at various heights, rotating to different positions, and locking securely at each position. The same structural elements serve both rotational and support functions, reducing overall complexity.
3Reliability
If a locking mechanism is implemented to secure the footrest in desired positions, then stability is improved, but the ease of operation may be reduced
Solution Approach 1:
The locking mechanism incorporates spring-loaded buttons that automatically engage and disengage based on the footrest's position. When the footrest rotates to a locked position, the spring mechanism automatically secures it without requiring additional user action, while still allowing easy release when needed.
Solution Approach 2:
Complex multi-step locking procedures are replaced with a simplified spring-loaded button system. The mechanical advantage is provided by the spring mechanism itself, which uses elastic potential energy to maintain the locked state without requiring continuous user input or complex cam mechanisms.

AI summary
An infant highchair is provided. The infant highchair includes a base having a plurality of legs and a footrest positioned between a first and a second leg of the base. The footrest includes two rotators configured to rotate the footrest into a first position for foot support and a second position for foot support. The footrest includes a bottom support having a first planar surface opposite a second planar surface and the two rotators configured to rotate the footrest at least 180°. The footrest includes two locking mechanisms configured to lock the footrest in at least one position for foot support. The footrest includes two release actuators, each release actuator configured to release a respective locking mechanism.
