Rotatable Child Seat Tray With Angle-Locking Pivot Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child seat trays are either fixed, causing difficulty for children to sit in and out, or are detachable but complicated to install and lack flexibility in angle adjustment, failing to meet diverse feeding requirements.
Innovation Solution
A rotatable tray with an angle adjusting function, featuring a platform, fixing base, positioning base, resilient component, and supporting base, allowing the tray to pivot and adjust its angle relative to the child seat without detachment, using a mechanism of engaging teeth and a resilient component for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the tray is fixed on the child seat, then the tray stability is improved, but the child cannot easily sit in and get out of the child seat and might get hurt
Solution Approach 1:
The tray is designed with a rotatable platform that can pivot relative to the supporting base through an engaging base, allowing the tray to transition from a fixed stable state to a dynamic adjustable state. This enables the tray to adapt to different usage scenarios - stable during feeding and movable when the child needs to enter or exit the seat.
2Ease of operation
If a detachable tray is used, then the ease of sitting in and out is improved, but the detachment and installation are complicated and the tray is not flexible for different requirements
Solution Approach 1:
The tray is divided into multiple functional components: a platform for holding items, a rotatable supporting base with engaging base, and a positioning mechanism with engaging portions. This segmentation allows the tray to be easily attached and detached while maintaining operational simplicity and flexibility for different feeding requirements.
3Stability of the object's composition
If the tray is fixed relative to the child seat, then the tray stability is improved, but the flexibility for different requirements is reduced
Solution Approach 1:
The platform is designed to rotate relative to the supporting base through the engaging base mechanism, allowing the tray angle to be adjusted according to different feeding requirements. The resilient component enables smooth rotation while the positioning base with engaging teeth provides stable positioning at desired angles, combining adaptability with stability.
Solution Approach 2:
The tray system allows changing the angular parameter of the platform relative to the supporting base. By adjusting the rotation angle through the engaging base and resilient component mechanism, the tray can adapt to different feeding positions and requirements while maintaining stability through the positioning mechanism with multiple engaging teeth.
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
Enables easy and rapid adjustment of the tray's angle, facilitating child access to the seat while maintaining stability and convenience in feeding, without the need for complex detachment or installation processes.
Implementation Method 1
The resilient component is disposed between the fixing base and the positioning base
Implementation Method 2
An engaging base protrudes from an end of the supporting base, and a second engaging portion is disposed on the supporting base. The engaging base is pivoted in the communicating chamber so that the platform rotates relative to the supporting base

AI summary
A rotatable tray is installed on a child seat for accommodating a container, and the rotatable tray includes a platform, a fixing base, a positioning base, a resilient component and a supporting base. The platform includes a communicating chamber, and the fixing base is fixed in the communicating chamber. The positioning base includes a first engaging portion, and the positioning base is slidably disposed in the communicating chamber. The resilient component is disposed between the fixing base and the positioning base. The supporting base is connected to the platform, an engaging base protrudes from an end of the supporting base, and a second engaging portion is disposed on the supporting base. The engaging base is pivoted in the communicating chamber so that the platform can rotate relative to the supporting base. The resilient component drives the first engaging portion to selectively engage with the second engaging portion.
