Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current stroller mounting systems are heavy, do not allow compact folding, and make it difficult to transition between forward and rearward facing configurations of child support accessories.

Innovation Solution

A mounting system with fixtures on the stroller frame and connectors on child support accessories that allow easy locking and unlocking in either configuration, enabling the stroller to be collapsed with accessories installed, using a mechanism with slots and catching structures for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional mounting system is used to attach child support accessories to the stroller frame, then the accessory can be securely mounted, but the stroller frame becomes heavy and cannot be compactly folded

Engineering Contradiction:

Improvesecure mounting of accessoryVSAvoidstroller frame weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The mounting system is divided into separate components: mounting fixtures attached to the stroller frame and connectors attached to the child support accessory. These segments can be independently optimized - the fixtures remain on the lightweight frame while the connectors provide secure attachment to the accessory, allowing the frame to be compact without adding significant weight.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mounting fixtures and connectors act as intermediary elements between the stroller frame and child support accessory. These intermediaries provide the secure mounting function without requiring the frame itself to be heavy or complex, as the fixtures and connectors handle the attachment load.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a traditional mounting system is used, then the accessory can be attached to the frame, but the system does not allow compact folding of the stroller

Engineering Contradiction:

Improveattachment securityVSAvoidstroller folded volume

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

By segmenting the mounting system into frame-mounted fixtures and accessory-mounted connectors, the design allows the frame to be folded compactly while the connectors maintain attachment security. The fixtures are positioned to not interfere with the folding mechanism, enabling compact storage without compromising attachment reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mounting system is designed to be dynamic rather than static - the fixtures and connectors allow the frame to move between extended and folded states while maintaining secure attachment. The design accommodates the dynamic folding motion without requiring the accessory to be removed or the frame to be overly heavy.

Inventive Principle:

Principle #15Dynamics

3Reliability

If a traditional mounting system is used, then the accessory can be fixed in position, but transitioning between forward and rearward facing configurations is difficult to operate

Engineering Contradiction:

Improveaccessory position stabilityVSAvoidconfiguration transition ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The mounting system transitions from a static fixed-position design to a dynamic reconfigurable design. The fixtures and connectors are positioned and oriented to accommodate multiple configurations (forward and rearward facing), allowing easy transition between states while maintaining position stability in each configuration through the secure locking mechanism.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The mounting fixtures and connectors are designed with universal functionality to support multiple configurations. The same fixtures can accommodate both forward and rearward facing orientations, eliminating the need for separate mounting systems for each configuration and simplifying the transition operation for the user.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Volume of moving object

If the stroller frame is designed for compact folding, then portability is improved, but the mounting system becomes more complex

Engineering Contradiction:

Improvestroller folded volumeVSAvoidmounting system complexity

Core Design Contradiction:

Volume of moving objectVSDevice complexity

Solution Approach 1:

Segmenting the mounting system into simple fixtures and connectors reduces overall complexity compared to a monolithic mounting system. Each component can be independently simplified - the fixtures are basic attachment elements on the frame, and the connectors are simple locking mechanisms on the accessory, making the entire system easier to manufacture and assemble while enabling compact folding.

Inventive Principle:

Principle #1Segmentation

AI summary

A mounting system includes at least one mounting fixture affixed on a stroller frame, and a connector affixed on a child support accessory. The connector can be inserted into the mounting fixture for locking the child support accessory in position on the stroller frame. The connector can lock with the mounting fixture in either of a rearward or forward facing configuration of the child support accessory. The construction of the stroller frame is such that it can be conveniently collapsed with the child support accessory installed thereon. Examples of the child support accessory can include a stroller seat module, a support adapter for carrycot or bassinet, and the like.
