Solution Overview

Problem

Conventional walker trays are not universally removably attachable and often obstruct the user's view, increasing the risk of tripping and falling due to their opaque design and improper fitting on various walker models.

Innovation Solution

A walker tray with laterally opposed handle-receiving apertures and a tray support portion made from light-transmissive material, featuring a tray-to-walker attachment mechanism that allows for secure and adjustable fitting on different walker designs, enabling better visibility and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional walker trays are used, then they provide item support functionality, but they obstruct the user's view and increase tripping risk

Engineering Contradiction:

Improveitem support functionalityVSAvoidobstruction of user's view

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The tray is made from light-transmissive material that allows users to see through it, changing the optical property from opaque to transparent to eliminate the view obstruction problem while maintaining the item support function

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The tray design incorporates apertures that segment the tray surface, allowing light to pass through and providing visibility while still maintaining structural integrity for supporting items

Inventive Principle:

Principle #1Segmentation

2Ease of manufacture

If conventional walker trays are used, then they provide item support, but they are not universally attachable to different walker models

Engineering Contradiction:

Improveitem support capabilityVSAvoidcompatibility with different walker models

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The attachment mechanism is designed with adjustable features that can accommodate multiple walker models and configurations, making the tray universally attachable while maintaining secure item support functionality

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The attachment mechanism includes adjustable and adaptable components that can be configured to fit different walker designs, providing dynamic adaptability across various walker models

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If conventional walker trays are used, then they are attached to the walker, but they cannot be easily removed or adjusted

Engineering Contradiction:

Improveattachment securityVSAvoidremovability and adjustability

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The attachment mechanism is designed to be both secure during use and easily removable or adjustable when needed, providing dynamic operation that switches between stable attachment and easy detachment

Inventive Principle:

Principle #15Dynamics

AI summary

A walker tray is removably attachable to a walker for enabling a user to support items. In some embodiments, the walker tray is light-transmissive for enabling a user to see through the tray. The walker tray includes a tray-to-walker attachment mechanism, and in this regard, some embodiments either include a pair of laterally opposed handle-receiving apertures or resilient clip elements. In those embodiments having handle-receiving apertures for mounting the tray upon the walker, each aperture has an aperture and an aperture width. The aperture lengths and aperture widths are configured to receive at least upper handle portions of a walker. Each of the handle-receiving apertures are defined inwardly by an inner leg-engaging edge configured to engage at least a forward leg portion and a rearward leg portion. Together the forward and rearward leg portions and the inner leg-engaging edge are cooperable to support the walker tray upon the walker.
