Rotatable Child Seat Tray With Angle-Locking Engagement
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 inflexible, lacking the ability to adjust angles for different needs.
Innovation Solution
A rotatable tray with a platform, fixing base, positioning base, resilient component, and supporting base, allowing the tray to adjust its angle relative to the child seat through a mechanism of engaging teeth and a resilient component, enabling easy installation and adjustment without detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tray is fixed on the child seat for stability, then the tray remains stable, 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 rotate relative to the supporting base through an engaging base with pivoting motion. This dynamic structure allows the tray to transition from a fixed stable state to a movable state, enabling children to easily enter and exit while maintaining stability when needed.
Solution Approach 2:
The tray is divided into multiple functional components: a platform, a supporting base, an engaging base with pivoting mechanism, and a positioning mechanism with engaging teeth. This segmentation allows independent optimization of each component - the supporting base provides stability while the platform with pivoting engaging base provides mobility for child access.
2Ease of operation
If a detachable tray is used for easy child access, then the child can easily sit in and out, but the detachment and installation are complicated
Solution Approach 1:
The positioning mechanism uses a resilient component that can be compressed to disengage the engaging teeth, and automatically releases when the rotation force is removed. This dynamic engagement system simplifies the attachment and detachment process compared to conventional fixed mechanisms, allowing easy operation while maintaining structural integrity.
3Reliability
If the detachable tray is fixed relative to the child seat after installation, then the tray is stable, but it is not flexible for different requirements
Solution Approach 1:
The platform is designed to rotate relative to the supporting base through the pivoting engaging base, allowing the tray angle to be adjusted to different positions. The resilient component and engaging teeth provide stable positioning at each angle while maintaining the ability to rotate, thus achieving both stability and adaptability.
Solution Approach 2:
The tray system allows changing the angular parameter of the platform relative to the supporting base. By rotating the platform to different angles and using the positioning mechanism to lock at desired positions, the system adapts to different feeding requirements while maintaining stability through the engaging tooth mechanism.
4Adaptability or versatility
If the tray is made detachable for flexibility, then the tray can be removed, but the detachment and installation process becomes complicated
Solution Approach 1:
The positioning mechanism is designed to automatically engage and disengage the engaging teeth through the resilient component. When the platform rotates, the resilient component compresses and releases, causing the engaging teeth to automatically lock or unlock without requiring manual intervention, thus simplifying the detachable operation.

AI summary
A rotatable tray (1) is installed on a child seat (2) for accommodating a container (4), and the rotatable tray includes a platform (3), a fixing base (6), a positioning base (7), a resilient component (8) and a supporting base (9). The platform (3) includes a communicating chamber (33), and the fixing base (6) is fixed in the communicating chamber (33). The positioning base (7) includes a first engaging portion (72), and the positioning base (7) is slidably disposed in the communicating chamber (33). The resilient component (8) is disposed between the fixing base (6) and the positioning base (7). The supporting base (9) is connected to the platform (3), an engaging base (90) protrudes from an end of the supporting base (9), and a second engaging portion (92) is disposed on the supporting base (9). The engaging base (90) is pivoted in the communicating chamber (33) so that the platform (3) can rotate relative to the supporting base (9). The resilient component (8) drives the first engaging portion (72) to selectively engage with the second engaging portion (92).
