Solution Overview

Problem

Existing stroller frames often require separate adapters for different types of child carriers and accessories, leading to increased costs, waste, and complexity in maintenance and storage.

Innovation Solution

A multi-purpose stroller adapter with a rotatable hub that can switch between configurations to support different types of connectors for various child carriers and accessories, reducing the need for multiple adapters and minimizing interference between connectors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate adapters are used for different carrier types, then each adapter can be optimized for its specific carrier type, but the number of adapters increases leading to higher costs, more waste, and greater maintenance complexity

Engineering Contradiction:
Improvecarrier connection reliabilityVSAvoidnumber of adapters
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The adapter incorporates multiple connector types (first connector and second connector) within a single device, allowing it to interface with different carrier types (infant carrier and toddler seat) using a unified adapter structure. This eliminates the need for multiple separate adapters while maintaining optimized connections for each carrier type.

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

2Adaptability or versatility

If multiple adapters are maintained for different carrier types, then each adapter can be specialized, but storage, maintenance, and selection become more complex and time-consuming

Engineering Contradiction:
Improvecarrier type compatibilityVSAvoidadapter selection and storage
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines multiple adapter functions into a single integrated adapter assembly that can accommodate different connector types. This merging reduces the number of separate components users need to store and manage, while still providing compatibility with multiple carrier types through the unified adapter design.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If a single adapter supports multiple connector types, then costs and waste are reduced, but connector interference may occur affecting connection stability

Engineering Contradiction:
Improvenumber of adaptersVSAvoidconnection stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The adapter divides its connector interface into distinct, separated connector types (first connector and second connector) positioned at different locations on the adapter body. This segmentation prevents physical interference between different connector types while maintaining stable connections, allowing each connector to function independently without affecting the other.

Inventive Principle:
Principle #1Segmentation

AI summary

This description is related to an adapter that can be coupled to a stroller frame (e.g., to one side of the stroller frame) or other child product and that is changeable between a first configuration for supporting a first type of accessory (e.g., stroller accessory) and a second configuration for supporting a second type of accessory. The adapter can include a hub that is rotatable relative to the stroller frame or child product and can include a first connector and a second connector positioned at different locations relative to the hub. In examples, when the hub is rotated to a first position, the first connector can be in position to support the first type of accessory, and when the hub is rotated to the second position, the second connector can be in position to support the second type of accessory.
