Accessory Connector Hook Foot Cart Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no convenient and effective way to removably attach a variety of objects to a cart designed for holding and carrying household or office items, limiting the ability to add additional accessories.
Innovation Solution
An accessory connector with a disk, hook, and foot design that allows for removable attachment to the cart by connecting the hook to the rim and the foot to the corner of the cart's sidewall, enabling the secure attachment of various accessories such as roll holders, bins, and tag plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If accessories are attached to the cart, then additional storage and carrying options are provided, but there is no convenient and effective way to removably attach them
Solution Approach 1:
The accessory connector is divided into separate components: a hook portion that engages with the rim and a foot portion that engages with the corner. This segmentation allows each component to be optimized for its specific function and enables easy assembly and disassembly of accessories from the cart
Solution Approach 2:
The accessory connector acts as an intermediary device between the accessory and the cart. It provides a standardized interface with specific geometric features (hook and foot) that match corresponding features on the cart, enabling removable attachment without direct modification of either the accessory or cart
2Reliability
If accessories are permanently attached to the cart, then secure attachment is achieved, but removability is lost
Solution Approach 1:
The attachment system transitions from a static permanent connection to a dynamic removable connection. The hook and foot are designed with specific geometries that provide stable engagement during use (reliability) while allowing intentional disengagement (removability). The connector maintains its position securely during normal cart operation but can be easily removed when needed
Solution Approach 2:
By dividing the connector into separable hook and foot components that engage with distinct features on the cart, the system enables reliable attachment through precise geometric matching while maintaining the ability to remove and reattach the accessory connector as needed

AI summary
An accessory connector includes a disk having an upper end and a lower end, a front side and a back side. A hook is positioned at the upper end of the back side of the disk, and a foot is positioned at the lower end of the back side of the disk, and extending laterally away from the disk. An accessory is positioned on the front side of the disk, so that the accessory can be attached to a cart by attaching the accessory connector to the cart.
