Crib Handrail Locking Structure for Visible Incomplete Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crib handrails can incompletely lock, leading to potential accidents due to hidden friction and cloth coverage, making it difficult for users to detect incomplete locking, which may result in crib collapse.
Innovation Solution
A handrail structure with a locking mechanism and pivoting members that include openings allowing the handrail to move and rotate when not fully locked, ensuring automatic collapse and visible indication of incomplete locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the handrail tube is covered by cloth to improve aesthetics, then the appearance is improved, but the ability to detect incomplete locking deteriorates
Solution Approach 1:
The patent uses visual indication through color or transparency changes to show locking status. The handrail tube or indicator element changes appearance (e.g., becomes transparent, changes color, or reveals a different color) to clearly indicate whether the locking mechanism is properly engaged, allowing users to detect locking status without removing the cosmetic cover.
2Shape
If the handrail tube is covered by cloth to improve aesthetics, then the appearance is improved, but the automatic collapse function deteriorates
Solution Approach 1:
The patent segments the handrail structure into functional components: the cosmetic cover, the handrail tube, and the locking mechanism. The handrail tube itself serves as both the structural element and the automatic collapse indicator, while the cosmetic cover is separated as an independent aesthetic layer that does not interfere with the mechanical collapse function.
Solution Approach 2:
The patent introduces an intermediary indicator element or uses the handrail tube itself as a mediator between the locking mechanism and the user. This intermediary provides visual feedback about locking status and enables automatic collapse indication without requiring the user to remove or interact with the cosmetic cover.
3Stability of the object's composition
If friction between rivet and circular hole is used to maintain stability, then the holding effect is improved, but the reliability of complete locking deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the position of the handrail tube or an indicator element provides visual information about the locking status. When the locking mechanism is not fully engaged, the handrail tube can shift position or change appearance, providing immediate feedback to the user that the locking is incomplete, thereby preventing reliance on insufficient friction alone.
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 handrail structure automatically collapses and visibly indicates incomplete locking, preventing accidents by ensuring the crib remains stable only when fully locked.
Implementation Method 1
the friction between the rivet and the circular hole 100 and the holding effect of the stretched covering cloth

AI summary
A handrail structure adapted to a crib comprises a handrail member, a locking mechanism and a first pivoting member. A first pivoting portion of the handrail member is pivotally connected to the locking mechanism by the first pivoting member. A second pivoting portion of the handrail member is pivotally connected to a support member by a second pivoting member. The locking mechanism is capable of selectively locking or releasing the first pivoting portion. The second pivoting portion has an opening formed thereon and the second pivoting member is movably disposed in the opening. The second pivoting member abuts against a first edge of the opening when the locking mechanism locks the first pivoting portion. The handrail member is capable of being rotated with respect to at least one of the locking mechanism and the support member when the second pivoting member abuts against a second edge of the opening.
