Solution Overview

Problem

Existing stroller rocking devices are either not portable, require attachment to specific strollers, or condition children to a continuous motion, leading to impractical use and potential overuse due to sudden stopping and lack of environmental adaptation.

Innovation Solution

A compact stroller rocking device with motorized rolling elements that automatically start and stop based on user gesture, featuring pressure sensors and a control module to adjust movement parameters, ensuring ease of use and adaptability to the child's needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a roller or friction wheel device is used to drive the stroller wheel, then the stroller can be rocked automatically, but the device must be attached to the stroller and is not suitable for every type of stroller

Engineering Contradiction:
Improvecompatibility with different stroller typesVSAvoidattachment requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a intermediary platform with rolling elements that mediates between the user and the stroller. This platform receives the stroller wheel on top and rolls on the ground below, transferring the rocking motion without requiring direct attachment to the stroller structure. This resolves the contradiction by providing universal compatibility while maintaining simple device structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a platform device with stroller wheels placed on it is used, then the stroller can be rocked, but the device is not portable due to considerable size

Engineering Contradiction:
ImproveportabilityVSAvoiddevice size
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The patent employs dynamic rolling elements that can move and adapt to different positions. The rolling means are designed to roll on the ground and can be positioned flexibly, allowing the device to maintain a compact form when not in use while providing adequate rocking motion when activated. This enables portability without sacrificing operational effectiveness.

Inventive Principle:
Principle #15Dynamics

3Extent of automation

If the device operates with predefined cycles and fixed frequency, then the stroller can be rocked automatically, but the child's sleep may be conditioned to a specific continuous motion

Engineering Contradiction:
Improveautomatic rocking operationVSAvoidadaptation to child's needs and environment
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The patent implements periodic rocking action through rolling elements that move back and forth in controlled cycles. The system provides automatic operation with periodic motion patterns that can be adjusted in duration and intensity, allowing the child to be rocked without continuous uninterrupted motion, thereby preventing sleep conditioning while maintaining automation.

Inventive Principle:
Principle #19Periodic action

4Reliability

If the device has a switch located on the device itself under the stroller, then the device can be controlled, but switching on and off is inconvenient and may lead to overuse

Engineering Contradiction:
Improvecontrol functionalityVSAvoidease of switching
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The device is designed to be self-starting through the rolling mechanism. When the user manually rolls the device or places the stroller on it, the rolling action automatically initiates the rocking motion without requiring the user to locate and operate a switch. The device stops automatically when the rocking cycle is complete, eliminating the need for manual switching and preventing overuse.

Inventive Principle:
Principle #25Self-service
