Solution Overview

Problem

Conventional walkers attached to wheelchairs are either custom-made or cannot be used independently once detached, limiting their versatility and functionality.

Innovation Solution

A connector apparatus with side assemblies and attachment hardware allows for detachable connection of a conventional walker to a wheelchair, enabling vertical and horizontal adjustments, and includes hinged legs for support when the walker is disconnected, allowing both the walker and wheelchair to be used independently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If custom-made walkers are attached to wheelchairs, then the attachment is secure and tailored, but the device complexity and manufacturing cost increase

Engineering Contradiction:

Improveattachment securityVSAvoidcustom fabrication requirements

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The connector apparatus is designed with universal attachment features that can be used with any conventional walker and wheelchair, eliminating the need for custom-made solutions. The standardized clamps and mounting brackets can attach to various walker frames and wheelchair structures, providing secure attachment without custom fabrication while maintaining reliability across different device combinations

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If adjustable connector apparatus is designed, then patient comfort is improved, but the device complexity increases

Engineering Contradiction:

Improvepatient comfort and fitVSAvoidadjustment mechanisms

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The connector apparatus incorporates dynamic adjustment features including telescoping side assemblies that allow height adjustment, and articulating legs that can be positioned at various angles. These adjustments enable customization for patient comfort and proper fit. The mechanisms use simple pin-and-slot or cam-based adjustments that are easy to operate but provide sophisticated adaptability, balancing comfort improvements with acceptable complexity
