Solution Overview

Problem

There is a need for a device that can assist or train children to walk safely outside of the household, as existing walking assistance devices are typically confined to home use and do not provide a viable solution for outdoor transportation.

Innovation Solution

A child walking assembly detachably connected to a stroller, featuring adjustable first and second mounting mechanisms, arms, and a handle that can be raised, lowered, and adjusted in length to accommodate different stroller sizes and child heights, allowing the child to walk behind the stroller while being supported.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing walking assistance devices are used, then children can learn to walk, but they are confined to home use and cannot be used for outdoor transportation

Engineering Contradiction:

Improveusability locationVSAvoidsafety

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines a stroller with a walking assistance device into a single integrated system. The mounting mechanisms attach the walking device to the stroller frame, allowing the child to transition from being pushed in the stroller to walking behind it while still attached to the same apparatus. This merging resolves the contradiction by enabling both outdoor transportation (stroller function) and walking training (assistance device function) within a single versatile system.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The stroller assembly is designed to perform multiple functions: it can transport the child in the stroller seat, or it can support the child as they learn to walk behind the stroller. The mounting mechanisms and support structure are universal in that they serve both transportation and training purposes, eliminating the need for separate home-only walking devices and outdoor strollers.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If a parent carries the child in a carrier, then the child is transported, but it becomes increasingly difficult as the child grows and the child does not want to be constrained for long periods

Engineering Contradiction:

Improveease of carryingVSAvoidchild size accommodation

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The walking assistance device features adjustable mounting mechanisms that can be repositioned along the stroller frame to accommodate children of different sizes and developmental stages. As the child grows, the mounting points can be moved to adjust the height and position of the support arms, maintaining ease of operation across a range of child sizes and ages.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The device allows adjustment of key parameters including the vertical position of the mounting mechanisms on the stroller frame, the length of the support arms, and the distance between mounting points. These parameter changes enable the same device to accommodate infants who need more support as well as older toddlers who are becoming more independent walkers.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If the parent holds or carries the child, then the child is transported, but the parent cannot hold other items needed for transportation

Engineering Contradiction:

Improveparent hands-free capabilityVSAvoidchild support safety

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The walking assistance device enables the child to support themselves as they walk behind the stroller, eliminating the need for the parent to physically hold or carry the child. The child grasps the handle or holds onto the support structure independently, allowing the parent to use both hands for other tasks such as shopping or navigating crowded areas while the child walks alongside.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The stroller assembly acts as an intermediary between the parent and the child during walking training. Instead of direct physical contact between parent and child, the mounting mechanisms and support structure mediate the interaction, providing stable support while allowing the parent to maintain distance and use hands for other purposes.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Adaptability or versatility

If the child walks behind the stroller, then the child can learn to walk outdoors, but the mounting mechanisms must be securely attached to the stroller frame

Engineering Contradiction:

Improveoutdoor walking trainingVSAvoidmounting mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting system is divided into separate modular components: mounting brackets that attach to the stroller frame, adjustable support arms, and connection points for the walking handle. This segmentation allows each component to be independently adjusted and secured, simplifying the overall attachment process while maintaining security for outdoor use.

Inventive Principle:

Principle #1Segmentation

AI summary

A child walker assembly is detachably connected to a stroller so as to extend away therefrom and enable the child to grasp and use a handle of the assembly for balance and support while walking as the parent pushes the stroller. The assembly is adjustable in width and/or length. The handle may be raised or lowered to be positioned at an appropriate height for the child.
