Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension devices with point-like damping elements lead to irregular and unreliable damping, causing discomfort and mattress deterioration, as they deform independently and fail to provide a uniform surface for weight absorption.
Innovation Solution
A suspension device featuring a perforated reception plate carried by a damping element, with a stud positioned below the plate, allowing the plate to compress and provide a larger, more reliable damping surface, and a second level of support that engages once the first level is stressed, enhancing cushioning and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If point-like damping elements are used to form the first level of damping, then the device structure is simplified, but the damping becomes irregular and unreliable, and the surface for weight absorption is non-uniform
Solution Approach 1:
The first level of damping is segmented into multiple independent point elements that can deform individually, while the second level provides a continuous support surface. This segmentation allows each point element to function independently while collectively providing reliable damping through the combination of both levels.
Solution Approach 2:
The invention transitions from a single-level point element structure to a two-level hierarchical structure, adding a vertical dimension with the first level (point elements) and second level (continuous surface). This dimensional addition resolves the contradiction by providing both structural simplicity and damping reliability through multi-level support.
2Ease of manufacture
If point elements are used for the first level of damping, then the device is simpler to manufacture, but the mattress suffers deterioration due to clashes during deformation
Solution Approach 1:
The second level of damping acts as a pre-positioned cushioning layer beneath the point elements. When point elements deform and potentially clash with the mattress, the second level provides a protective interface that absorbs impact energy before it reaches the mattress, preventing deterioration while maintaining manufacturing simplicity.
3Device complexity
If multiple point elements are used for damping, then the device structure is simpler, but the mattress cannot slide smoothly to follow dynamic deformations
Solution Approach 1:
The damping system is segmented into point elements at the first level that can deform independently, allowing localized adjustments. This segmentation enables the mattress to slide smoothly over the deforming elements while maintaining overall structural simplicity, as each point element can move without constraining adjacent elements.
4Reliability
If a larger damping surface is provided, then weight absorption is more reliable and homogeneous, but the device complexity increases
Solution Approach 1:
The invention achieves a larger effective damping surface by adding a second level of damping beneath the point elements. This vertical dimensionality change allows the system to provide both homogeneous weight absorption across the extended surface and maintain relatively simple device structure, as the two levels work hierarchically rather than requiring complex lateral expansion.

AI summary
The device (1) has a reception plate (2) for receiving a damping element (5), and a stud (3) placed at a side of a lower face (21) of the plate and opposite to an upper face (22) of the plate. The plate is displaced from a rest position to a cushioning position under an effect of a compression force directed from the plate to the stud. The damping element is released and maintains the plate away from the stud in the rest position. The damping element is compressed in the cushioning position such that the plate is linked to the stud that projects from the upper face of the plate. An independent claim is also included for a mattress base comprising a frame.
