Walking Frame Holder with Segmented Tray and Pockets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accessories for walking frames do not effectively support the transportation of a wide range of items, including plated meals, hot drinks, and essential items like mobile phones and remote controls, while also failing to prevent lateral movement and spillages.
Innovation Solution
A holder configured for attachment to a mobility frame, featuring an open-topped body with a tray and multiple pockets that engage the crossbar of the frame, providing support for plates and organizing essential items in easy-to-reach locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a flat tray surface is used for carrying items, then it provides a stable platform for transporting plates and meals, but it does little to stop lateral movement of items and cannot organize small items effectively
Solution Approach 1:
The tray is segmented into multiple functional zones: a flat carrying surface for plates, vertical pockets for small items (mobile phone, remote control, glasses), and side pockets for additional storage. This segmentation allows different types of items to be organized in appropriate locations, preventing lateral movement while maintaining the stability of the flat surface for plate transport.
Solution Approach 2:
The design transitions from a two-dimensional flat tray surface to a three-dimensional structure by adding vertical pockets that depend from the tray. These pockets extend downward to hold small items securely, utilizing the vertical dimension to prevent lateral movement while keeping the original flat surface intact for plate carrying.
2Quantity of substance
If existing caddies are used for storage, then they provide a trough for small items, but they cannot transport plates of food or hot drinks and do not help with organizing items for easy retrieval
Solution Approach 1:
The caddy is divided into multiple separate pockets of different sizes and configurations. Small items like mobile phones, remote controls, and glasses can be placed in specific pockets, making them easily locatable and retrievable. This segmentation maintains storage capacity while dramatically improving ease of operation through organized placement.
Solution Approach 2:
Different pockets are designed with different characteristics - some are open-top for quick access, others have specific dimensions for particular items. This local differentiation of pocket qualities allows items to be stored in the most appropriate location for their size and frequency of use, enhancing both storage efficiency and retrieval ease.
3Reliability
If accessories are designed to fit particular brands or models only, then they provide precise compatibility, but they reduce versatility across different walking frame models
Solution Approach 1:
The holder is designed with universal attachment mechanisms that can accommodate different crossbar diameters and configurations found across various walking frame models. The attachment system uses adjustable components that can adapt to different frame geometries, allowing the same holder design to be reliably mounted on multiple brands and models while maintaining secure attachment.

AI summary
A holder configured for attachment to a mobility frame that has a crossbar at its upper part, the holder comprising an open-topped body, a tray at an upper part of the body, a plurality of pockets depending from the tray and opening into the tray, the configuration of the holder being such that, in use, at least some of the pockets engage opposite sides of the crossbar at the upper part of the mobility frame with the tray providing a support for plates.
