Solution Overview

Problem

Individuals pushing strollers or wheelchairs often face challenges in finding comfortable seating, especially in outdoor settings, leading to fatigue and discomfort, particularly for caregivers and those with mobility issues.

Innovation Solution

A collapsible and swivel-secured chair, termed 'Buddysitter', which can be easily deployed and retracted from strollers or wheelchairs, providing a comfortable seating option that can be attached as an auxiliary seat, allowing users to rest without the need for separate seating or carrying a bulky chair.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separate chair is carried for resting, then comfortable seating is available, but the device becomes bulky and difficult to transport

Engineering Contradiction:

Improveseating availabilityVSAvoidchair weight

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

The chair is designed to collapse and nest within the stroller or wheelchair frame when not in use, allowing the seating structure to be stored compactly within the existing device boundaries without requiring separate carrying

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If a collapsible chair is attached to stroller or wheelchair, then seating is available without carrying separate chair, but the device complexity increases

Engineering Contradiction:

Improveseating accessibilityVSAvoidchair structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The chair employs dynamic folding mechanisms and swivel joints that allow it to transition between deployed and collapsed states, providing seating functionality when needed while automatically reducing to a compact form that integrates with the stroller or wheelchair frame

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The chair structure is divided into modular segments including the seat, backrest, and support legs that can independently fold and collapse, allowing the entire assembly to be compacted within the stroller or wheelchair frame without complex locking mechanisms

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If the chair is deployed from stroller or wheelchair, then comfortable seating is provided, but the storage space is reduced

Engineering Contradiction:

Improveseating comfortVSAvoidstorage space

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The chair collapses and nests within the existing stroller or wheelchair frame structure, utilizing the available internal space and contours of the parent device to store the chair when not in use, thereby minimizing the reduction of storage space

Inventive Principle:

Principle #7Nested doll (Nesting)
