Solution Overview

Problem

Child cribs often have gaps between handrails and posts due to assembly errors, posing a risk of finger insertion and injury to children.

Innovation Solution

A child crib design featuring a frame body with handrails and posts, a corner component connected to both, and a covering member with a detachable connecting assembly that encloses the corner components using ring-shaped openings and buckles or zippers to prevent finger insertion into gaps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a frame body with handrails and posts is used to construct the child crib, then the structural integrity and stability are improved, but gaps may form between the handrails and connecting components or between the posts and connecting components due to assembly errors, creating a safety hazard

Engineering Contradiction:

Improvestructural stabilityVSAvoidgap formation causing finger insertion risk

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

A covering member is introduced as an intermediary component between the frame body parts (handrails and posts) to cover and eliminate the harmful gaps. The covering member includes a covering body with ring-shaped opening structures that enclose the corner components, preventing finger insertion into gaps while maintaining the structural integrity of the crib frame.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The covering member is constructed with a flexible covering body that can be detached and reattached. The covering body includes fabric or flexible material with ring-shaped opening structures that can conform to the corner components, providing flexible coverage over the gaps while allowing for easy installation and removal.

Inventive Principle:

Principle #30Flexible shells and thin films

2Object-affected harmful factors

If a covering member is added to cover the corner components and eliminate gaps, then safety is improved by preventing finger insertion, but the device complexity increases due to additional components

Engineering Contradiction:

Improvefinger insertion preventionVSAvoidnumber of components

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The covering member is segmented into a covering body and a connecting assembly that can be detachably connected. The covering body includes ring-shaped opening structures that cover the corner components, while the connecting assembly with combining structures allows for easy attachment and detachment from the frame body, simplifying installation and maintenance while maintaining safety functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The covering member is designed with detachable connecting structures that allow it to be dynamically attached and removed from the frame body. The connecting assembly includes combining structures that enable easy connection to the handrails and posts, allowing the covering member to be installed or removed as needed without permanently altering the crib structure.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If a detachable connecting assembly is used to attach the covering member, then ease of operation is improved by allowing easy installation and removal, but reliability may be reduced due to potential detachment

Engineering Contradiction:

Improveinstallation and removal convenienceVSAvoidattachment stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The connecting assembly incorporates combining structures designed with sufficient connection strength to prevent accidental detachment during normal use. The combining structures are beforehand designed to provide reliable attachment while still allowing intentional removal, cushioning against the risk of unintended detachment while maintaining ease of operation.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A child crib includes a frame body, a corner component, a cloth component and a covering member. The cloth component at least partially covers the frame body. The corner component is connected to a handrail and a post of the frame body and exposed out of the cloth component. A first ring-shaped opening structure and a second ring-shaped opening structure are respectively formed by a first side and a second side of a covering body of the covering member. When the first side of the covering body is connected to a first side of the cloth component, by positioning the second side of the covering body on a second side of the cloth component, the first side and the second side of the cloth component are respectively enclosed by the first ring-shaped opening structure and the second ring-shaped opening structure, and the covering member covers the corner component.
