Solution Overview

Problem

Existing adjustable baby cribs are either heavy and costly with complex mechanisms, or lightweight and inexpensive but lacking the ability to convert into a baby bed, posing safety risks and operational challenges.

Innovation Solution

A lightweight, collapsible baby crib made of textile materials with a simple zipper mechanism that allows adjustable height changes, enabling conversion from a bassinet to a baby bed, featuring a flexible textile enclosing element and a frame that can be easily transported.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a complex mechanical mechanism is used to adjust the bottom wall height in prior art cribs, then the crib can adapt to baby's growth stages, but the device complexity increases and requires adult intervention that may cause back pain

Engineering Contradiction:
Improveadaptability to baby's growthVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The side walls are divided into multiple telescopic segments that can slide relative to each other along the longitudinal axis. Each segment contains a zipper that can be independently opened or closed, allowing incremental height adjustment without complex mechanical mechanisms. This segmentation enables simple, step-by-step adaptation to baby's growth stages.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The side walls are designed with telescopic capability, allowing them to dynamically change length along the longitudinal axis. The zippered segments enable the side walls to be easily extended or retracted, providing dynamic height adjustment that adapts to the baby's growth without requiring complex fixed-position mechanisms.

Inventive Principle:
Principle #15Dynamics

2Strength

If a heavy wooden bottom wall and rigid side bars are used in prior art cribs, then the structural strength is sufficient, but the weight increases and makes the crib difficult to transport

Engineering Contradiction:
Improvestructural strengthVSAvoidcrib weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The side walls are constructed from flexible textile materials instead of rigid wood, allowing the crib to be lightweight yet maintainable. The textile side walls can be folded and compressed, enabling easy transport while still providing sufficient structural support when assembled. The flexibility of the textile material reduces weight while maintaining the enclosing function.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The crib combines different materials with complementary properties: textile materials for the side walls and bottom wall provide lightness and flexibility, while metal or rigid components in the frame structure provide necessary strength and stability. This composite approach achieves both lightweight portability and adequate structural strength.

Inventive Principle:
Principle #40Composite materials

3Stability of the object's composition

If the bottom wall is made heavy and rigid in prior art cribs, then the structural stability is maintained, but the ease of operation decreases when adjusting the bottom wall height

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

Solution Approach 1:

The bottom wall is divided into multiple detachable segments that can be easily removed and repositioned. Each segment can be independently handled, making adjustment simple and requiring minimal effort. The segmented design maintains structural stability when assembled while enabling easy operation during height adjustment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bottom wall is designed to be dynamically reconfigurable, allowing it to be easily moved between different height positions. The detachable segment design enables the bottom wall to be quickly repositioned without requiring heavy lifting or complex mechanical operations, improving ease of operation while maintaining stability at each position.

Inventive Principle:
Principle #15Dynamics

4Strength

If wooden bars are used in prior art cribs, then the structural strength is sufficient, but the safety risk from baby impact increases

Engineering Contradiction:
Improvestructural strengthVSAvoidimpact hazard to baby
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The side walls are made from flexible textile materials that can absorb and dissipate impact energy, reducing the harmful effects when a baby accidentally bumps against them. The textile material provides a softer, more forgiving surface compared to rigid wooden bars, while still maintaining the structural enclosing function through the frame support.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The crib uses a composite construction where textile side walls are combined with a rigid frame structure. The frame provides the necessary structural strength, while the textile covering reduces impact hazards by providing a softer surface that contacts the baby, eliminating the need for bare wooden bars.

Inventive Principle:
Principle #40Composite materials

5Weight of moving object

If textile materials are used in lightweight cribs, then the cost and weight are reduced, but the ability to convert into a baby bed is lost

Engineering Contradiction:
Improvecrib weightVSAvoidconversion to baby bed
Core Design Contradiction:
Weight of moving objectVSAdaptability or versatility

Solution Approach 1:

The side walls are designed with telescopic capability, allowing them to be extended or retracted along the longitudinal axis. By opening the zippers and sliding the segments, the side walls can be lengthened to create the higher edges required for baby bed configuration, or shortened for bassinet mode. This dynamic adjustment enables versatile conversion while maintaining lightweight textile construction.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The crib is designed as a universal product that can function in multiple modes: bassinet mode with shorter side walls for newborns, and baby bed mode with extended side walls for older infants. The telescopic side wall mechanism with adjustable zippers provides this multi-functionality, allowing a single lightweight textile crib to replace both separate products.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An adjustable baby crib (1), which adapts to the growth of the baby by being switched, for instance, into a baby bed, comprises a frame (2) and an enclosing element (7), which comprises a bottom wall (3), and side walls (4). The side walls (4) are made of a flexible material and delimit, with the bottom wall (3), a cavity configured for receiving the baby. The frame (2) comprises an upper portion (21) for supporting the side walls (4), and support members (22) which are configured to rest on the ground and support the upper portion (21) of the frame (2). The crib (1) comprises a zipper (5), associated with the side walls (4), and adapted to be manually actuated to switch the crib (1) between a first configuration and a second configuration, in which the distance D1 in the longitudinal direction (X-X) between the bottom wall (3) and the top edge (41) of the side walls (4) in the first configuration is smaller than the distance D2 in the second configuration.
