Solution Overview

Problem

Existing child holding accessories for play yards are often expensive and cumbersome, requiring multiple purchases or frequent changes to accommodate different uses such as changing tables and sleeping beds, which complicates storage and usage.

Innovation Solution

A child holding accessory with a reversible resting support and adjustable fixtures that can be attached to a rigid support frame, allowing for multiple configurations such as a changing table and a child sleeping bed, with bearing surfaces that deform differently to provide appropriate firmness and curvature for each use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate child holding accessories are purchased for different uses (changing table, sleeping bed), then functional versatility is improved, but cost and storage complexity increase

Engineering Contradiction:

Improvefunctional versatilityVSAvoidstorage complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The accessory integrates multiple functional regions (changing table region, sleeping bed region) into a single unit that can be attached to the play yard frame. The reversible support structure allows the same physical object to serve different functions by rotating 180 degrees, eliminating the need for multiple separate accessories and reducing storage complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines previously separate accessories (changing table and sleeping bed) into one integrated accessory assembly. The support structure merges the functionality of multiple items while the reversible design allows dynamic reconfiguration between different uses, resolving the contradiction between versatility and complexity.

Inventive Principle:

Principle #5Merging (Combining)

2Device complexity

If a single accessory serves multiple functions, then storage convenience is improved, but the ability to provide specialized support for different uses may be compromised

Engineering Contradiction:

Improvestorage convenienceVSAvoidspecialized support capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The accessory features different regions with specialized bearing surfaces optimized for specific functions: a first region with a first bearing surface for changing table use and a second region with a second bearing surface for sleeping bed use. Each region is designed with local quality characteristics appropriate for its intended function, while the reversible support structure allows switching between them.

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If the bearing surface is designed for firm support, then stability is improved, but comfort for sleeping may be reduced

Engineering Contradiction:

Improvesupport firmnessVSAvoidcomfort for different uses

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The reversible support structure is designed to rotate 180 degrees between two stable positions, allowing the bearing surface to dynamically reconfigure between different functional states. The support structure maintains stability in each position while enabling transition between firm support mode and comfortable sleeping mode through rotation.

Inventive Principle:

Principle #15Dynamics

AI summary

A child holding accessory includes a reversible resting support and at least one fixture for attaching the resting support with a rigid support frame. The reversible resting support has a first and a second bearing surface facing opposite directions, the first and second bearing surfaces respectively having different profiles, and each of the first and second regions being positionable to be upwardly facing to receive a child thereon.
