Car Seat Back Tray Bracket With Fold-Out Multi-Use Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing car seat back brackets do not provide a versatile and convenient solution for passengers to store and use electronic devices, food, and beverages during a ride, as they lack a multi-purpose design that can accommodate various items and ensure safe usage.
Innovation Solution
A tray bracket structure for car seats that includes a fixing unit, a hanging board with adjustable positioning components and clips, a pivotally connected tray, and a placement unit with elastic bands and mesh bags, allowing for the secure attachment of portable electronics, food, and beverages, while also accommodating cartons and providing a temporary desktop.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a simple bracket structure is used, then the device complexity is reduced, but the versatility and functionality for accommodating multiple items are insufficient
Solution Approach 1:
The bracket structure integrates multiple functions into a single device: a tray for food and beverages, a cup holder, and a clamp for electronic devices. This allows the bracket to serve multiple purposes (eating, drinking, entertainment) simultaneously, resolving the contradiction by providing versatility without requiring separate devices for each function.
Solution Approach 2:
The patent combines previously separate components (tray, cup holder, device clamp) into a single integrated bracket assembly that mounts to the car seat. This merging of functions into one structure achieves multi-purpose functionality while maintaining a unified, manageable design rather than multiple separate attachments.
2Adaptability or versatility
If a fixed bracket structure is used, then the stability is improved, but the adaptability to different positions and configurations is reduced
Solution Approach 1:
The bracket incorporates adjustable elements including a movable tray with positioning holes, an adjustable clamp with movable jaws, and a repositionable cup holder. These dynamic components allow the structure to adapt to different configurations and sizes while maintaining secure fixation through engagement mechanisms that ensure stability in each positioned state.
Solution Approach 2:
The bracket is divided into separable functional modules (tray, cup holder, clamp) that can be independently adjusted and positioned. Each module can be configured separately and then integrated, allowing adaptability in each component while the overall assembly maintains stability through their coordinated engagement with the mounting structure.
3Ease of operation
If the tray is always extended, then the usability for passengers is improved, but the space consumption when not in use is excessive
Solution Approach 1:
The tray is designed as a movable component that can be extended to a horizontal position for use and retracted to a vertical position against the bracket body when not needed. This dynamic positioning allows the tray to provide full usability when required while minimizing space occupation during storage, resolving the contradiction between accessibility and compactness.
4Adaptability or versatility
If multiple components are integrated, then the multi-purpose functionality is improved, but the ease of installation and adjustment is reduced
Solution Approach 1:
The bracket components are pre-configured with standardized engagement features such as positioning holes, clamping mechanisms, and mounting interfaces. These preliminary design elements allow for tool-free or minimal-tool assembly and adjustment, making installation convenient despite the integrated multi-functional nature of the device.

AI summary
A tray bracket for car seat back is provided, including: a fixing unit, a hanging board, a tray, and a placement unit. The fixing unit is for fixing to at least one pillar on a car seat supporting a headrest; the hanging board has a back area and a front area with opposite positions. The back area is disposed with an array of positioning components with different heights. The fixing unit is engaged with one of the positioning components. The front area is distributed with several clips; the tray is pivotally connected to the bottom of the hanging board, the tray is tightly attached to the hanging board in the folded state, and can be horizontal and perpendicular to the hanging board when opened. The other side of the tray is provided with the placement unit, for placing a carton between the placement unit and the tray.
