Solution Overview

Problem

Existing child containment devices, such as play yards and bassinets, often lack improved mattress support systems that ensure comfort, safety, and convenience, particularly in maintaining the structural support and flatness of mattresses for infants and small children.

Innovation Solution

The introduction of a support structure with a periphery aligning with the device's walls and retractable support members to maintain a flat mattress configuration, along with structural couplings between mattress panels allowing repositioning between expanded and compact states, and a chamfered corner assembly to prevent curling, enhances the mattress support and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a raised bassinet mattress is provided to support the infant above the floor for easier access by caregiver, then the convenience and ease of operation is improved, but the structural support and flatness of the mattress becomes more difficult to maintain

Engineering Contradiction:

Improveease of access by caregiverVSAvoidstructural support and flatness of mattress

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The support members are configured to be retractable, allowing them to extend when needed to maintain mattress flatness and retract when not needed, adapting to different operational states of the bassinet

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The support structure is divided into multiple individual support members distributed across the mattress support surface, with each member independently maintaining flatness in its respective area, allowing localized adjustment without affecting the entire structure

Inventive Principle:

Principle #1Segmentation

2Stability of the object's composition

If retractable support members are added to maintain mattress flatness, then the structural support is improved, but the device complexity increases

Engineering Contradiction:

Improveflatness of mattressVSAvoidcomplexity of support structure

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The support members are configured to automatically extend and retract based on the mattress position and weight distribution, eliminating the need for manual intervention or complex control mechanisms to maintain flatness

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The support members act as intermediary elements between the mattress and the bassinet frame, providing the necessary structural support while allowing the mattress to remain removable and interchangeable without direct complex mechanical connections

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If structural couplings are added to allow repositioning of mattress panels between expanded and compact states, then the adaptability is improved, but the manufacturing precision requirements increase

Engineering Contradiction:

Improverepositioning between expanded and compact stateVSAvoidprecision of panel alignment

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The mattress is divided into multiple panels that can be independently positioned and connected through structural couplings, allowing the mattress to be reconfigured between expanded and compact states while maintaining alignment through standardized connection interfaces

Inventive Principle:

Principle #1Segmentation
