Rollator Hand Grip with Forward Standing Support

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional rollators do not provide adequate support for users when standing up, as the hand grips are primarily designed for walking assistance and do not effectively assist in vertical balance or weight transfer during the standing process.

Innovation Solution

A rollator design featuring a second hand grip part positioned in front of the first hand grip part, with enhanced dimensions and shaping to provide additional support for standing up, including a wider and inclined surface that allows users to enclose their hand and transfer weight, and a protruding part for increased stability and counterbalancing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the hand grip is designed for walking assistance only, then the structure remains simple, but it cannot provide adequate support for standing up

Engineering Contradiction:

Improvesupport functionVSAvoidhand grip structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hand grip is divided into two distinct parts: a first hand grip part for walking assistance and a second hand grip part for standing up support. This segmentation allows each part to be optimized for its specific function while maintaining overall structural simplicity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The hand grip assembly serves multiple functions: the first part assists during walking movement while the second part provides support during standing up. This multi-functionality increases adaptability without requiring completely separate devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a second hand grip part is added for standing up support, then standing support is improved, but the device complexity increases

Engineering Contradiction:

Improvestanding up supportVSAvoidhand grip structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

By segmenting the hand grip into two parts with distinct functions, the patent improves standing up support reliability while keeping each individual part relatively simple in structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The two hand grip parts are combined into a single integrated assembly that attaches to the rollator frame, providing multiple functions through a unified structure rather than separate components.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If the second hand grip part is positioned further forward, then it provides better leverage for standing up, but it may interfere with the user's reach to the first hand grip part

Engineering Contradiction:

Improvestanding up assistanceVSAvoidspatial arrangement

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The second hand grip part is positioned forward along the longitudinal axis of the rollator, utilizing the longitudinal dimension to provide leverage for standing up without interfering with the lateral hand placement needed for controlling the first hand grip part.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
