Child Bassinet Adjustable Height Coupling for Playpen Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child bassinets attached to playpens are limited to a single fixed position, which may not accommodate varying configurations of use, such as needing a higher position for access or a lower position for safety when the child is sleeping.
Innovation Solution
A child bassinet with a playpen coupling mechanism that includes an adjustable catching part, allowing the bassinet to be installed at different heights on a playpen by moving between a locked state at one height and an unlocked state for adjustment between heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bassinet accessory is attached at a fixed position on the playpen, then the attachment system is simple and stable, but the bassinet cannot accommodate different configurations of use (higher position for access vs. lower position for safety)
Solution Approach 1:
The bassinet attachment system transitions from a fixed static position to a dynamic adjustable system. The coupling mechanism includes a movable coupling element that can be positioned at multiple heights on the playpen frame, allowing the bassinet to be attached at different elevations. This dynamic adjustment capability enables the system to adapt between higher positions (facilitating access) and lower positions (improving safety during sleep), directly resolving the technical contradiction between adaptability and device complexity.
Solution Approach 2:
The attachment system is divided into separate functional components: a coupling element with multiple engagement positions, a movable connection mechanism, and a locking system. This segmentation allows each component to perform its specific function independently, making the overall system manageable despite increased complexity. The coupling element can be adjusted to different segments of the playpen frame, providing height adjustability while maintaining structural integrity.
2Ease of operation
If the bassinet is installed at a higher position on the playpen, then access to the child is facilitated, but safety may be compromised when the child is sleeping
Solution Approach 1:
The system provides dynamic height adjustment capability, allowing users to change the bassinet elevation based on the child's needs. When access is required, the bassinet can be positioned higher on the playpen frame for easier reaching. When the child is sleeping, the bassinet can be lowered to a safer position. This dynamic repositioning capability directly addresses the safety-access contradiction.
Solution Approach 2:
The key parameter being changed is the height position of the bassinet on the playpen frame. The coupling mechanism enables continuous or discrete adjustment of this parameter, allowing optimization between access ease (higher position) and safety (lower position) depending on the operational context. Users can modify the height parameter to match different usage scenarios.

AI summary
A child bassinet includes a support frame supporting an enclosure, and a playpen coupling mechanism provided on the support frame. The playpen coupling mechanism includes an adjustable catching part that is connected with the support frame and is engageable with a playpen for installing the child bassinet thereon. The catching part is movable relative to the support frame between a first and a second position of different elevations, and is further movable relative to the support frame between a locked state where the catching part engages with the support frame for locking the catching part in the first or second position, and an unlocked state where the catching part is disengaged from the support frame for movement of the catching part between the first and second position. The catching part is adjustable between the first and second position for installing the child bassinet on the playpen at different heights.
