Collapsible Bottle Rack for Shopping Carts with Multi-Size Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for holding and transporting bottles in shopping carts do not effectively engage cylindrical objects like bottles, particularly at their neck or body, and lack adaptability for various bottle sizes and collapsibility.
Innovation Solution
A substantially planar rack with receiving spaces of varying sizes, attachable to the shopping cart's top surface, that engages bottles at their neck or body, featuring a collapsible design for easy storage and removal, using materials like wood, plastic, or metal, with fastening mechanisms like clips or hooks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a planar rack with receiving spaces is used to engage bottles, then bottles can be securely held in a single plane, but the rack occupies space when not in use
Solution Approach 1:
The rack is designed to be collapsible, transforming from an extended configuration that securely holds bottles to a collapsed configuration that minimizes storage space. The collapsible mechanism allows the rack to dynamically change its volume while maintaining its bottle-holding function when deployed.
2Adaptability or versatility
If the rack is designed to engage bottles at their neck or body, then bottles of various sizes can be secured, but the rack structure becomes more complex
Solution Approach 1:
The rack features receiving spaces with specific local geometries designed to engage bottles at particular locations (neck or body). Each receiving space has tailored dimensions and engagement features that adapt to different bottle sizes and shapes, allowing the rack to handle various bottle types without requiring a completely different design for each size.
3Adaptability or versatility
If the rack is made attachable to the shopping cart top surface, then the rack is adaptable to different cart configurations, but the attachment mechanism increases device complexity
Solution Approach 1:
The rack incorporates a universal attachment mechanism with clips or hooks that can engage with various cart top surface configurations. The same attachment mechanism works across different cart models and configurations, providing multi-functionality without requiring multiple specialized attachment systems.
4Adaptability or versatility
If the rack features receiving spaces of varying sizes, then bottles of different dimensions can be held, but manufacturing precision requirements increase
Solution Approach 1:
The rack is divided into multiple discrete receiving spaces, each with specific dimensions tailored to different bottle sizes. This segmentation allows each receiving space to be optimized for particular bottle types while maintaining overall rack functionality. The modular segmented design simplifies manufacturing by allowing individual receiving spaces to be produced and assembled with standard tolerances.

AI summary
A rack for holding or securing bottles adaptable to a shopping cart that is useful for holding or securing and transporting bottles such as, for instance, beverage bottles is described herein. Also, a shopping cart containing such a rack is described. The rack is substantially planar and features a plurality of receiving spaces, substantially circular in shape, and of varying sizes, adapted to engage or restrain the bottles in only one place or in only one plane. The rack may be adapted for fastening or locking engagement to a shopping cart and may feature any suitable fastener or locking mechanism, and it may be rigid or collapsible, or completely removable from the shopping cart.
