Solution Overview

Problem

Existing stroller passenger assemblies are not adaptable to different types of strollers without significant hardware modifications, reducing interchangeability and convenience.

Innovation Solution

A modular passenger assembly with adjustable components, including a platform, attachment arms, and handle extensions, that can be easily attached and detached from various stroller frames, allowing for height, width, and pitch adjustments, and featuring multiple attachment mechanisms for secure and removable installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a stroller passenger assembly is designed to be securely attached to a stroller frame, then reliability and security are improved, but adaptability to different stroller types deteriorates due to requiring significant hardware modifications

Engineering Contradiction:

Improveattachment securityVSAvoidstroller type adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The attachment arms are designed with universal adaptability to interface with multiple stroller frame types through various attachment mechanisms (seat belt integration, frame clamping, universal joints), allowing the same passenger assembly to be securely attached to different stroller models without requiring significant hardware modifications

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The attachment system is divided into separate, interchangeable components including attachment arms, attachment mechanisms, and interface elements that can be configured differently to match various stroller frame types, maintaining secure attachment while enabling adaptability

Inventive Principle:

Principle #1Segmentation

2Reliability

If mounting hardware is permanently installed on the stroller to secure the passenger assembly, then attachment security is improved, but ease of operation and interchangeability deteriorate

Engineering Contradiction:

Improveattachment securityVSAvoidassembly removal and transfer

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The attachment mechanisms are designed to transition between locked and unlocked states, allowing the passenger assembly to be securely attached during use but easily removed and transferred to another stroller when needed, with features like release levers and detachable connectors

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The attachment system includes pre-configured attachment arms and mechanisms that are ready for quick connection and disconnection, allowing the assembly to be rapidly installed or removed from the stroller frame without complex assembly or disassembly procedures

Inventive Principle:

Principle #10Preliminary action

AI summary

The present invention is a passenger assembly for a stroller and is adaptable to almost any stroller and is capable of practice in numerous embodiments. The preferred embodiment features a chassis mounted platform with adjustable mounting arms. A mounting mechanism is located at the terminus of each arm and is attachable and removable from the stroller frame with the passenger assembly. A number of potential mounting mechanisms are disclosed. An extension handle is provided to allow users greater control of the stroller from a distance further than normal, as the assembly occupies the position proximate the stroller, where the user ordinarily stands. Modules are capable of addition to the assembly, such as a seat or basket, or a stow strap for securement of the assembly when not in use.
