Infant Crib with One-Hand Moveable Sidewall for Safe Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant cribs pose challenges in accessing and safely returning sleeping infants due to limited access openings and tall sidewalls, often leading caregivers to co-sleep with infants, which is hazardous, and bassinettes have weight and safety limitations that restrict their use.
Innovation Solution
An infant crib with a selectively moveable sidewall that can be opened and closed using one hand, providing side access and a retaining mechanism to secure the sidewall in place, allowing caregivers to comfortably care for and return infants without disturbing them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cribs with tall fixed sidewalls are used, then infant safety is improved by preventing falls and escapes, but caregiver access to the infant is worsened making it difficult to retrieve or place infants
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed sidewall into a movable sidewall that can be selectively repositioned. The sidewall includes a movable portion that can be slid along the crib frame between a first position (providing full enclosure for safety) and a second position (providing open access for caregiver interaction). This dynamic adjustment allows the crib to adapt between safety mode and access mode, resolving the contradiction between infant safety and caregiver ease of operation.
2Ease of operation
If bassinettes with movable sidewalls are used to improve access, then caregiver access is improved, but infant safety is worsened due to shorter sidewalls and weight limits
Solution Approach 1:
The patent applies the universality principle by designing a crib that combines the safety features of traditional cribs (tall sidewalls meeting CPSC height requirements) with the access features of bassinets (movable sidewalls). The movable sidewall mechanism allows the same crib structure to provide both secure enclosure when needed and easy access when needed, eliminating the need to choose between safety-oriented traditional cribs and access-oriented bassinets. This multi-functional design resolves the contradiction by making a single device capable of serving both safety and access requirements.
3Ease of operation
If drop-side cribs are used to improve access, then caregiver access is improved, but reliability is worsened due to hardware loosening and entrapment risks
Solution Approach 1:
The patent applies the taking out principle by removing the problematic drop-side mechanism (hardware that can loosen and create entrapment hazards) and replacing it with a simpler movable sidewall design. The new design eliminates complex drop-side hardware, tracks, and locking mechanisms that have historically caused safety issues. Instead, it uses a straightforward movable portion that can be manually repositioned along the frame, taking out the harmful elements while retaining the beneficial access feature.
4Ease of operation
If co-sleeping is used to improve ease of infant care, then caregiver access is improved, but infant safety is worsened due to strangulation and suffocation risks
Solution Approach 1:
The patent applies the intermediary principle by providing the movable sidewall as a mediating mechanism that enables safe infant care without requiring co-sleeping. The movable sidewall acts as an intermediary that allows caregivers to easily access and interact with infants within the safe confines of the crib, eliminating the need to place infants on adult beds. This intermediary mechanism resolves the contradiction by providing the ease of access that co-sleeping would give, but through a safe alternative that maintains infant-proper separation.

AI summary
An infant crib is provided that includes at least one stationary sidewall and a positionable sidewall that is selectively moveable relative to the stationary sidewall between a fully closed position and a fully open position. When the positionable sidewall is in the fully open position a side access opening providing access to an enclosure defined within the infant crib is provided. The positionable sidewall includes a cover that extends over the moveable sidewall. The crib also includes a retaining mechanism assembly including a channel defined therein. At least a portion of the positionable sidewall is sized and shaped to be received within the channel when the moveable sidewall is in the fully closed position. The positionable sidewall is removeable from the retaining mechanism assembly and is selectively moveable by a user using only one hand.
