Play Yard Bassinet with Strap-Adjustable Backrest Inclination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional play yards lack an adjustable inclination feature for the bassinet, which limits user flexibility in positioning the sleep area for optimal comfort and safety.
Innovation Solution
A play yard design incorporating a frame body, a bassinet with an adjustable backrest, and an adjusting mechanism that allows the effective length of a strap to be changed, enabling the inclination of the backrest to be adjusted between 14° to 21° through a connecting unit and an engaging element that pivots between engaged and disengaged positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bassinet backrest inclination angle is fixed, then the structure is simple and stable, but the adaptability to different user needs is poor
Solution Approach 1:
The bassinet backrest is designed with adjustable inclination angles (14° to 21°) through a strap mechanism with connecting units, allowing the structure to dynamically adapt to different user needs while maintaining overall structural stability
Solution Approach 2:
The inclination angle parameter of the bassinet backrest can be changed between 14° and 21° by adjusting the strap length and connecting unit position, enabling the same structure to provide different positioning configurations
2Ease of operation
If the strap effective length is made adjustable, then the backrest inclination can be customized, but the device complexity increases due to the connecting unit mechanism
Solution Approach 1:
The connecting unit enables dynamic adjustment of the strap effective length, allowing users to easily change the backrest inclination angle by moving the connecting unit along the strap between engaged and disengaged positions
Solution Approach 2:
The strap mechanism is divided into segments with connecting units at specific positions, allowing independent adjustment of strap effective length while maintaining the overall integrity of the bassinet structure

AI summary
A play yard includes a frame body having first and second sides, a bassinet, a strap and a connecting unit. The bassinet is disposed between the first and second sides, includes a backrest and has a lower end portion attached to the frame body, and an upper end portion mounted with the backrest. The strap has a fixed end fastened to the first side, and a free end connected to the second side, and supports the upper end portion. The connecting unit connects the free end to the second side such that an effective length of the strap between a portion of the strap disposed within the connecting unit and the fixed end is adjustable to change an inclination of the backrest when the free end moves relative to the connecting unit.
