Infant safety barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant safety devices for elevated furniture, such as diaper changing tables, often compromise between providing safety and allowing easy access, with existing solutions either being cumbersome or requiring counterweights, which may not adequately address the risk of an infant falling while also limiting user access.
Innovation Solution
A pivotable infant safety barrier system comprising a first and second mounting body, stanchions, and an elongated flexible barrier that can be reversibly adjusted between an upright safety position and a non-upright position for access, ensuring the barrier is taut when upright and slackens for access, with a securement mechanism that includes trunnions, pivot holes, and a locking detent system to maintain safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a safety barrier is installed to prevent infant falls, then safety is improved, but access to the infant becomes restricted
Solution Approach 1:
The barrier is designed as a pivotable assembly that can dynamically change between an upright safety position and a lowered access position. The stanchions rotate about horizontal axes, allowing the barrier to transition from blocking access to allowing access while maintaining safety when needed.
Solution Approach 2:
The barrier's orientation parameter is changed from upright (safety mode) to lowered (access mode). This parameter change allows the same physical barrier to serve dual functions: preventing falls when upright and allowing access when lowered.
2Ease of operation
If a pivotable barrier is made movable to allow access, then ease of operation is improved, but the risk of infant falling increases
Solution Approach 1:
The barrier is lowered into the access position before the caregiver needs to reach the infant, and returned to the upright safety position before the infant could potentially fall. This preliminary positioning ensures safety is maintained during the access operation.
Solution Approach 2:
The barrier remains in the lowered access position only for the brief duration necessary to complete the diaper changing task, then is quickly returned to the upright safety position. The unsafe state (lowered barrier) is minimized in time.
3Ease of operation
If spring-biased safety nets are used, then ease of operation is improved, but device complexity increases due to counterweight requirements
Solution Approach 1:
The counterweight mechanism is extracted from the barrier assembly. Instead of using springs and counterweights to bias the barrier, the invention uses the geometry of the pivot points and the weight of the barrier itself to achieve automatic return to the upright position.
Solution Approach 2:
The barrier assembly is designed to automatically return to its upright safety position after being lowered, without requiring external power sources, springs, or counterweights. The system uses its own weight and pivot geometry to self-correct to the safe position.

AI summary
In accordance with the subject invention, an infant safety barrier is provided which includes: a first mounting body; a second mounting body; a first stanchion pivotably mounted to the first mounting body so as to be reversibly pivotable between upright and non-upright positions; a second stanchion pivotably mounted to the second mounting body so as to be reversibly pivotable between upright and non-upright positions; and, an elongated flexible barrier a first end secured to the first stanchion and a second end secured to the second stanchion, wherein, with the first and second stanchions being in the upright positions, the flexible barrier is relatively taut between the first and second stanchions. Advantageously, with the subject invention, an infant safety barrier is provided which can be reversibly adjusted between an upright safety position, to restrict an infant's fall from an elevated location, and a non-upright position, allowing access to the infant.
