Solution Overview

Problem

Conventional play yards with permanently attached soft goods are difficult to clean and maintain due to the challenge of removing and washing the soft goods without damaging them or the rigid frame.

Innovation Solution

A play yard design featuring removable soft goods assemblies with guiding components, such as slots and tracks, and tensioning mechanisms that allow for easy detachment and reattachment, enabling thorough cleaning and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If soft goods are permanently attached to the rigid frame, then structural stability is improved, but ease of cleaning deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of cleaning
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The play yard is divided into two separable parts: a rigid frame structure and removable soft goods. The soft goods are not permanently attached but can be detached through guiding components and constraining clips, allowing the soft goods to be removed for cleaning while the frame remains stable during use.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If soft goods are permanently attached to the rigid frame, then structural stability is improved, but ease of repair deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of repair
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The soft goods are designed as separable modules that can be easily removed from the rigid frame through guiding components and constraining clips. This segmentation allows damaged soft goods to be quickly replaced without affecting the structural integrity of the frame, significantly improving ease of repair.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If soft goods are permanently attached to the rigid frame, then device complexity is reduced, but ease of operation deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoidease of operation
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

Guiding components and constraining clips serve as intermediary mechanisms between the soft goods and rigid frame. These intermediaries enable easy attachment and detachment of soft goods through simple user actions, improving ease of operation while maintaining relatively simple overall device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A play yard includes a plurality of corner posts, a plurality of rails, a floor structure and at least one soft good assembly. Each of the plurality of corner posts includes a first guiding component. Each of the plurality of rails is connected between two adjacent corner posts. The floor structure is connected to the plurality of corner posts. The soft good assembly includes soft goods, a soft goods connector and a second guiding component. The soft goods connector is fixed to the soft goods. The second guiding component is connected to the soft goods connector and adapted to be detachably assembled with the corner post via the first guiding component for tensioning the soft goods.
