Adjustable Baby Mattress Support With Locking Height Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby cribs require time-consuming and awkward assembly to adjust the mattress support height as the baby grows, leading to user discomfort and potential back pain during caregiving, and often have complex mechanisms for continuous height adjustment.
Innovation Solution
A system with a drive unit, actuator, and locking device that allows continuous vertical displacement of the mattress support, enabling easy height adjustment via a control panel and electric signals, with stabilizing means to prevent inadvertent movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual disassembly and reassembly of the main frame and brackets is used to adjust mattress support height, then the mattress support can be positioned at different height levels, but the operation becomes time-consuming and awkward causing user discomfort
Solution Approach 1:
The patent transforms the static, discrete height adjustment mechanism into a dynamic, continuous adjustment system. The mattress support can be smoothly moved between multiple height positions without disassembly, allowing adaptive positioning while maintaining structural integrity. This resolves the contradiction by enabling versatility through dynamic movement rather than static reconfiguration.
Solution Approach 2:
The patent replaces the manual mechanical assembly/disassembly system with an automated height adjustment mechanism. Instead of requiring users to manually disassemble and reassemble brackets and frame components, the system uses mechanical substitution to enable easy height changes through a different mechanism that eliminates the awkward assembly operations.
2Stability of the object's composition
If the mattress support is positioned at a set height, then the structure remains stable, but the attendant must repeatedly bend over causing back pains
Solution Approach 1:
The patent enables dynamic height adjustment of the mattress support, allowing the attendant to optimize the height for comfortable caregiving while maintaining structural stability. The mattress support can be continuously adjusted to different heights without compromising the crib's structural integrity, resolving the contradiction between stability and ease of operation.
3Adaptability or versatility
If complex mechanisms are used for continuous height adjustment, then the mattress support can be adjusted to any height, but the device complexity increases
Solution Approach 1:
The patent divides the height adjustment function into separate, independent components: the mattress support frame with its longitudinal members, the adjustable横 members, and the connection mechanisms. This segmentation allows continuous height adjustment through simple relative movements of segmented components rather than requiring a complex integrated mechanism.
Solution Approach 2:
The patent uses dynamic adjustment mechanisms where the mattress support frame members can move relative to each other along their lengths. This dynamic segmentation allows continuous height adjustment through simple translational movements rather than complex mechanical systems, maintaining simplicity while achieving versatility.

AI summary
A continuously height adjustable mattress support and apparatus therefor is disclosed. The mattress support is vertically displaceable by means of at least one drive unit for applying a vertical force to a corresponding solely vertically displaceable driven component and is stabilized during vertical displacement by at least one stabilizing means connected thereto. The driven component is connected to, or is in supporting relation with, the mattress support, so that a height of the mattress support above a floor surface is settable and continuously adjustable by means of at least one actuator associated with the at least one drive unit. In one embodiment, a locking device for preventing displacement of the mattress support following inadvertent actuation of the at least one drive unit is employed.
