Reversible-Holder Tray for Flexible Stroller and Wagon Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wagons and strollers lack adjustable and versatile food and drink holders that accommodate both children and additional items, leading to inconvenience and potential spills, especially in situations where space is limited or components are fixed, inhibiting movement and storage.
Innovation Solution
A tray apparatus with a base, sides, and reversible holder that can be affixed to a vehicle, allowing it to be positioned inside or outside, providing adjustable and removable support for food and drinks, and accommodating various sizes and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed tray or cupholder is provided in the wagon, then food and drink access is provided, but movement and storage within the wagon is inhibited
Solution Approach 1:
The tray apparatus is designed with movable components that allow it to be repositioned between inside and outside locations of the wagon. The tray can slide along the wagon body and be detached from the cupholder, enabling dynamic adaptation to different usage scenarios and resolving the contradiction between providing food access and maintaining storage flexibility.
Solution Approach 2:
The tray apparatus is divided into separate functional components: a tray body, a cupholder, and mounting mechanisms. This segmentation allows each component to be independently positioned or detached, enabling the tray to be moved inside or outside the wagon while maintaining food and drink access functionality.
2Adaptability or versatility
If a reversible holder is designed to fit inside or outside the vehicle, then placement flexibility is improved, but device complexity increases
Solution Approach 1:
The reversible holder is designed as a universal component that can perform multiple functions: securing the tray inside the wagon, positioning it outside for easy access, and serving as a detachable cupholder. This multi-functionality achieves placement flexibility without requiring multiple separate devices, thereby limiting the increase in overall device complexity.
Solution Approach 2:
The holder integrates multiple functions into a single component structure, combining the tray support, cupholder, and mounting mechanism into one unified reversible holder assembly. This merging reduces the number of separate parts and simplifies the overall device while maintaining placement flexibility.
3Ease of operation
If the tray is made removable and repositionable, then ease of operation is improved, but reliability of food and drink containment decreases
Solution Approach 1:
The tray apparatus includes pre-designed attachment mechanisms and positioning features that ensure reliable containment before use. The cupholder and mounting structures are configured to securely hold food and drink items in advance, maintaining reliability while allowing later repositioning or removal of the entire assembly.
