Collective Walking Aid With Child Seating and Stackable Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing walking assistance devices for the elderly and disabled are underutilized due to their bulkiness and strong medical connotation, limiting their use to private settings and shortening travel duration, and there is a need for a device that is socially acceptable and versatile for various environments.
Innovation Solution
A collective mobility assistance device with a rolling frame, including adult and child seats, foldable design, and stackable features, designed to be used in public spaces, reducing bulkiness and medical connotation while providing versatile mobility and rest functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional walkers are designed with medical features and support structures, then safety and support functionality are improved, but bulkiness and medical connotation increase leading to reduced social acceptance
Solution Approach 1:
The device combines multiple functions into a single unit: it serves as both a walker for elderly/disabled users and a stroller for children. The frame structure supports adult seating while also accommodating child seats, allowing the same device to be used in diverse social contexts without stigmatization
Solution Approach 2:
The patent merges the walker function with stroller function by integrating child seats into the walker frame. The rear wheels and frame structure serve both the adult user and attached child seats, creating a unified device that eliminates the need for separate medical equipment
2Stability of the object's composition
If walkers are designed for medical use with robust support structures, then stability and support are improved, but device bulkiness increases reducing portability and ease of storage
Solution Approach 1:
The device is segmented into modular components: the frame structure, adult seat, child seats, and wheels can be independently configured. The child seats are detachable and can be positioned at different locations on the frame, allowing the device to be compact when child seats are removed while maintaining stability when needed
3Device complexity
If conventional walkers are designed with fixed medical configurations, then structural simplicity is maintained, but adaptability to different users and environments is reduced
Solution Approach 1:
The device incorporates dynamic adjustability through detachable child seats that can be added or removed based on user needs. The frame allows for configuration changes where child seats can be attached to different parts of the structure, enabling the same basic design to adapt to various family compositions and environmental requirements
