Reversible Stroller Seat Rotatable Mount for Seamless Folding

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Strollers with reversible seats often require the seat to be removed or mounted in a specific orientation for the frame to collapse, leading to incomplete or inefficient folding due to protrusion or failure to collapse when mounted otherwise.

Innovation Solution

A collapsible stroller design with a rotatable mount for the reversible seat, allowing it to be oriented forward or rearward and collapse with the stroller frame without changing attachment points, using a single attachment point and position-regulating mechanisms to ensure parallel alignment of all components during folding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the reversible seat is mounted in a specific orientation for frame collapse, then the frame can be collapsed properly, but the stroller requires multiple attachment points or seat removal to accommodate different orientations

Engineering Contradiction:

Improveease of collapseVSAvoidnumber of attachment points

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The single attachment point on the stroller frame is designed to universally accommodate the reversible seat in both forward and rearward orientations. The attachment point includes a rotatable mount that can receive the seat joint assembly regardless of the seat's orientation, eliminating the need for multiple dedicated attachment points for different seat positions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The attachment point incorporates a rotatable mount that can dynamically adjust its orientation during the collapse process. When the stroller frame is collapsed, the mount rotates to allow the reversible seat to fold parallel to the frame tubes, enabling proper collapse regardless of whether the seat is mounted in forward or rearward orientation.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the reversible seat is mounted in any orientation other than the specified one, then the seat can be installed flexibly, but the seat will protrude outside the collapsed frame or fail to collapse

Engineering Contradiction:

Improveseat orientation flexibilityVSAvoidcollapse alignment

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The rotatable mount dynamically adjusts during collapse to maintain proper alignment. Whether the seat is mounted in forward or rearward orientation, the mount rotates during the collapse process to ensure the seat folds parallel to the frame tubes, preventing protrusion and ensuring complete collapse.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Instead of requiring the seat to be in a specific orientation for collapse, the invention inverts the approach by allowing the attachment point itself to rotate and adapt to the seat's orientation. This inversion of the constraint from the seat to the attachment point enables versatile seat mounting while maintaining proper collapse alignment.

Inventive Principle:

Principle #13The other way round (Inversion)

3Adaptability or versatility

If multiple attachment points are provided for different seat orientations, then all orientations can be accommodated, but the device complexity and cost increase

Engineering Contradiction:

Improveseat orientation accommodationVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

A single attachment point is designed to perform multiple functions: accommodating the reversible seat in both forward and rearward orientations, and enabling proper collapse in both configurations. This universal attachment point eliminates the need for manufacturing multiple specialized attachment points, reducing complexity and cost.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges the functionality of multiple orientation-specific attachment points into a single multi-functional attachment point. The rotatable mount combines the capabilities of what would otherwise require separate attachment points for forward and rearward seat orientations, simplifying the overall structure and reducing manufacturing requirements.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A collapsible stroller comprising a frame and a reversible seat (5) comprising an armrest portion (5.5) is provided. The reversible seat (5) is mountable via an attachment point on the stroller frame in either a forward or rearward orientation with respect to the stroller frame, and in such a way that the attachment point can be moved relative to the stroller frame for collapse of the reversible seat (5) along with the stroller frame, irrespective of the reversible seat's orientation. An associated reversible seat structure is also disclosed.
