Solution Overview

Problem

Existing strollers lack versatility in storage options, often requiring specialized hardware or containers that do not efficiently utilize space for both shelf and container modes.

Innovation Solution

A stroller designed to selectively operate between a shelf mode and a container mode, featuring a detachable storage unit that can be securely coupled to the frame using a latching mechanism, allowing for versatile storage configurations and modular use of space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a stroller uses a fixed shelf for storage, then the structure is simple and stable, but the storage versatility and adaptability are limited

Engineering Contradiction:
Improvestorage versatilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The storage system is divided into separate modular components: a detachable container unit that can be independently attached to or removed from the stroller frame. This segmentation allows the container to be used in multiple configurations (attached or detached) without complicating the overall stroller structure, resolving the contradiction between versatility and structural simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The storage system transitions from a static fixed shelf to a dynamic configuration where the container can be selectively attached and detached. This dynamic capability enables the storage system to adapt between different modes (attached for integrated storage, detached for portable use) while maintaining a simple base structure, thus achieving versatility without proportional increase in complexity.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a stroller includes a detachable container mode, then storage flexibility is improved, but the device complexity increases due to additional coupling mechanisms

Engineering Contradiction:
Improvestorage flexibilityVSAvoidcoupling mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container is designed with universal attachment features that can couple to the stroller frame in multiple positions and orientations. The same container can be used whether attached to the stroller or carried independently, eliminating the need for specialized hardware for each mode and reducing overall system complexity despite enhanced flexibility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

A simple latch mechanism serves as an intermediary coupling element that enables easy attachment and detachment of the container. This intermediary component provides the necessary connection functionality without requiring complex mechanical systems, thereby achieving storage flexibility while minimizing the increase in device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If a latching mechanism is used to secure the container, then the container coupling reliability is improved, but the ease of operation is reduced due to additional securing steps

Engineering Contradiction:
Improvecontainer coupling reliabilityVSAvoidcontainer attachment ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The latch mechanism is designed to automatically engage when the container is properly positioned on the stroller frame, eliminating the need for manual securing operations. The container's own weight and positioning trigger the latching action, providing reliable coupling without compromising ease of operation, as the system performs the securing function automatically.

Inventive Principle:
Principle #25Self-service

AI summary

There is provided a stroller (10) configured to selectively operate between a shelf mode and a container mode. In an illustrative example, a frame (15) of the stroller supports a seating module, and supports a shelf (40) disposed at least partially over a footprint (70) defined by multiple wheels of the stroller. In a shelf mode, items may, for example, be supported by the shelf (40) in a storage space over the footprint and at least partially under the seating module. In a container mode, a selected container (30) may, for example, be releasably coupled (e.g., by a latching mechanism) to the stroller frame (15) such that it extends into the storage space. Various embodiments may, for example, advantageously enable use of a preferred container style and/or shape while still enabling secure coupling of the container under the seating module.
