Adjustable Incline Sleeper with Rocking Control and Compact Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infant sleepers with fixed inclination angles are inadequate for allowing infants to sit up, necessitating removal for feeding, and lack adjustable rocking and compact storage options.
Innovation Solution
An adjustable incline sleeper with a lower base frame that can rock or remain stationary, an upper support frame with adjustable inclination, and a pivotable connection arrangement allowing for transverse movement and locking positions, enabling adjustable inclination and compact folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inclination angle is fixed and very small, then the structure is simple, but the infant cannot effectively sit up and feeding becomes inconvenient
Solution Approach 1:
The patent applies the dynamics principle by making the inclination angle adjustable rather than fixed. The upper support frame can be pivoted relative to the lower base frame to change the inclination angle between these frames, allowing the sleeper to adapt between a reclined position for sleeping and an upright position for feeding, thus resolving the contradiction between ease of feeding and structure complexity
Solution Approach 2:
The patent segments the frame into two independently movable parts: the lower base frame and the upper support frame. These frames are connected by a pivotable connection arrangement that allows relative movement, enabling the upper frame to be adjusted to different inclination angles while the lower frame remains stable, thereby achieving adjustable inclination without excessive structural complexity
2Adaptability or versatility
If the lower support members are curved to permit rocking, then the infant can be soothed by gentle rocking, but the sleeper cannot remain stable for feeding
Solution Approach 1:
The patent applies dynamics by making the rocking function controllable rather than continuous. The lower support members are curved to permit rocking, but include stop extensions that can be positioned to either allow gentle rocking motion or prevent rocking entirely by contacting the ground surface. This allows the sleeper to switch between rocking mode for soothing and stable mode for feeding
Solution Approach 2:
The patent extracts the rocking function from being a continuous state and makes it a controllable, selectable feature. The stop extensions on the lower support members can be positioned to either engage with the ground surface to prevent rocking or be positioned away to allow rocking, thus separating the rocking capability from the stable positioning requirement
3Volume of moving object
If the frame is X-shaped and collapsible, then storage and transportation are convenient, but the structural strength may be compromised
Solution Approach 1:
The patent segments the frame into the lower base frame and upper support frame connected by a pivotable connection arrangement. This segmentation allows the frame to be collapsed into a compact X-shaped configuration for storage and transportation while maintaining structural integrity when opened, as each segment can be independently positioned and locked
Solution Approach 2:
The patent applies preliminary action through the pivotable connection arrangement that pre-establishes the geometric relationship between the lower base frame and upper support frame. When opened, the frames form a stable X-shaped structure with predetermined angles that provide structural strength, while the same connection allows collapsing to a compact configuration for storage

AI summary
An adjustable incline sleeper includes a lower base frame including lower support members movable between a first rocking position which permits rocking of the adjustable incline sleeper in a transverse direction and a second non-rocking position which prevents rocking of the adjustable incline sleeper; an upper support frame; a covering body secured to the upper support frame for supporting an infant thereon; and a pivotable connection arrangement for connecting the upper support frame to the lower base frame in a manner to permit transverse pivotable movement of the upper support frame relative to the lower base frame to change an inclination angle between the upper support frame and the lower support frame.
