Crib bed with detachable side wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing latch and supporting assemblies for crib bed sides require excessive manual operation for attachment and detachment, posing a risk of accidental detachment by children and complicating hygienic cleaning.
Innovation Solution
A childproof, multi-action latch and supporting assembly that uses a gravity-actuated spring-loaded lock and a sloped surface to automatically secure the crib bed side wall, requiring a combination of horizontal and rotational motions to detach, ensuring secure attachment and safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual latches or screws are used to secure the crib bed side wall, then the attachment is secure, but the operation becomes complex and time-consuming
Solution Approach 1:
The latch assembly automatically secures the crib bed side wall to the crib bed frame without requiring manual intervention. The spring-loaded latch engages with the receiving piece when the side wall is positioned, creating a self-securing mechanism that eliminates the need for manual latching operations while maintaining secure attachment
Solution Approach 2:
The invention replaces complex manual latching mechanisms (screws, manual latches) with a spring-loaded automatic latch system. This mechanical substitution simplifies the operation from multiple manual steps to a single positioning action, while the spring mechanism provides reliable automatic engagement and retention
2Ease of operation
If simple latches are used for easy operation, then the detachment is easy, but children can accidentally detach the side wall
Solution Approach 1:
The detachment operation is segmented into two distinct actions: first pulling the trigger lever to disengage the latch, and then lifting the side wall. This segmentation ensures that a simple pull is insufficient for detachment, providing child safety while maintaining ease of operation for adults who can perform the sequential actions
Solution Approach 2:
The latch system transitions from a static secure state to a dynamic release state through the trigger mechanism. The trigger lever provides controlled movement that dynamically disengages the latch from the receiving piece, allowing intentional detachment while preventing accidental release by children who cannot manipulate the trigger mechanism
3Reliability
If the crib bed side wall is permanently attached, then safety is maximized, but cleaning and access become difficult
Solution Approach 1:
The automatic latch is designed to engage automatically when the crib bed side wall is positioned against the frame, creating a secure attachment before any cleaning or access operations are needed. This preliminary automatic securing action ensures safety is established in advance, while the detachable nature allows easy removal for cleaning when required
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
Facilitates easy and secure attachment of the crib bed side wall without manual latching, while providing a childproof mechanism for safe detachment and easy access for cleaning, enhancing safety and operational efficiency.
Implementation Method 1
The stationary latch piece is formed to guide the latch catching piece into the locked position, induced by the gravity actuated automatic spring-loaded lock under the weight of the detachable crib bedside.
Implementation Method 2
The stationary latch piece is formed to guide the latch catching piece into the locked position, induced by the gravity actuated automatic spring-loaded lock under the weight of the detachable crib bedside.

AI summary
The crib bed (1) has a crib sidewall (5) secured to the crib bed leg construction (7) by means of a latching system (6). A latching bar (13) is springloaded by means of a latch bar spring (14) for engagement of the latching pin (16) with a stationary guide member (19). The latching pin (16) is retractable into the latching bar (13) against the load of a spring (17) arranged in the latching bar by displacement of the latching pin along a sloped surface (22) of the stationary guide member (19). The latching pin (16) is secured to the latching bar (13) with a linkage pin (15) extending through a slot (18) of the latching pin and extending through a hole in the latching bar. The linkage pin (15) is guided in a guide rail (12) in the latch housing (11) for retraction of the secured latching pin.
