Over-the-Bed Bassinet With Auto-Restoring Access Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bassinets do not provide adequate access for mothers to their infants while ensuring infant safety, particularly in hospital settings where space constraints and the risk of suffocation or falling are significant, due to the limitations of traditional bassinet designs that either require mothers to leave their beds or pose ergonomic and safety concerns.
Innovation Solution
An over-the-bed bassinet with a convertible front wall that can be lowered for easy access and automatically returns to an elevated position to prevent the infant from rolling out, featuring a restoring mechanism such as springs or weighted arms, allowing mothers to nurse comfortably without risking the baby's safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bassinet uses a traditional standalone crib design, then infant safety is improved, but ease of access for mothers is worsened
Solution Approach 1:
The front wall of the bassinet is designed to be dynamically movable between an elevated position (providing safety barrier) and a lowered position (providing access). The wall can be lowered by applying force and automatically returns to the elevated position via a restoring mechanism, allowing mothers to easily access their infants while maintaining safety when not in use.
Solution Approach 2:
The height parameter of the front wall is changed from fixed to variable. The wall transitions between two discrete height states (elevated and lowered), enabling the bassinet to switch between safety mode and access mode. This parameter change resolves the contradiction by providing both safety and ease of access at different times.
2Ease of operation
If the bassinet places the infant close to the mother's bed, then ease of access is improved, but the risk of suffocation and falling is worsened
Solution Approach 1:
The movable front wall provides dynamic protection that adapts to the mother's needs. When the mother needs to access the infant, she lowers the wall; when she is not attending to the infant, the wall automatically returns to the elevated protective position. This dynamic barrier reduces the risk of suffocation and falling while maintaining close proximity to the mother's bed.
Solution Approach 2:
The restoring mechanism automatically returns the front wall to the elevated safety position without requiring manual intervention from the mother. This self-service feature ensures that the protective barrier is consistently restored after access, reducing the risk of harmful events even when the mother is tired or distracted.
3Reliability
If the bassinet requires the mother to get out of bed to access the infant, then infant safety is improved, but maternal rest is worsened
Solution Approach 1:
The movable front wall allows the mother to access the infant while remaining in bed. By simply lowering the wall with her hand or arm, the mother can attend to the infant without the energy expenditure and time loss associated with getting out of bed, while the automatic restoration maintains safety.
4Ease of manufacture
If the bassinet uses fixed enclosure walls, then manufacturing simplicity is improved, but ease of access is worsened
Solution Approach 1:
The front wall is designed as a simple movable component that slides or pivots within the bassinet structure. The restoring mechanism uses basic spring or elastic elements that are easy to manufacture and integrate. This dynamic design adds minimal manufacturing complexity while dramatically improving ease of access compared to fixed walls.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides ergonomic support for mothers, reduces the risk of infant suffocation and falling, and promotes better rest and safety for both mothers and infants by allowing easy access without compromising bed access or space, thus addressing the primary concerns of postpartum care and hospital safety.
Implementation Method 1
The restoring mechanism may comprise a spring mechanism that biases the convertible wall toward the elevated position from the lowered position
Implementation Method 2
or may be a weighted centering arm attached to displace the front wall upward from its lowered position

AI summary
An easy-access over-the-bed bassinet especially useful in hospitals for new mothers and babies. The bassinet has a barrier to prevent the infant from rolling off a sleeping platform, and one portion or wall of the barrier is convertible to permit a mother to reach in and cradle the infant, for breast-feeding for example. The convertible portion has a restoring mechanism such as a spring force or weighted arm to transform it back to its original barrier position upon removal of the weight of the mother's arms. The convertible portion may be a wall surrounding the sleeping platform that translates vertically into a frame, or pivot about a bottom edge, or pivot underneath the sleeping platform. The entire sleeping platform may tilt about a horizontal axis, and may rotate about a vertical axis for ease of positioning relative to the mother. The bassinets are mounted on sturdy frames that permit over-the-bed positioning of the sleeping platform, which can be raised or lowered to accommodate varying bed heights, and to assist nurses caring for the baby.
