Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mattress support devices with slats flex and sag under user weight, compromising comfort, while replacing slats with pads disrupts continuity of support across the mattress width, affecting user experience.
Innovation Solution
A support device with a slender crosspiece and elastic members arranged to densify near the center, providing enhanced support and maintaining continuity across the mattress width, featuring a lower section fixed to the bed frame, an upper section for mattress support, and an intermediate section connected by elastic members, with varying longitudinal spacings to manage sagging and support density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional slats are used to support the mattress, then continuity of support across the mattress width is maintained, but the slats significantly flex and sag under user weight, compromising comfort
Solution Approach 1:
The support device is divided into multiple independent elastic members (at least three) arranged along the crosspiece, each capable of individual deformation. This segmentation allows the system to maintain overall continuity while distributing the load across multiple flexible elements rather than a single rigid slat, reducing sagging through shared load-bearing capacity.
Solution Approach 2:
The elastic members are positioned at specific locations along the crosspiece (between ends and middle) to provide targeted support in regions most prone to sagging. The non-uniform distribution of elastic members creates locally optimized support zones that address the specific stress patterns experienced by mattress supports, enhancing resistance to sagging where it occurs most frequently.
2Strength
If pads are used instead of slats to reduce sagging, then resistance to sagging is improved, but discontinuity in support across the mattress width occurs, harming comfort
Solution Approach 1:
Multiple elastic members are combined along a single crosspiece structure, merging the benefits of flexible support (from individual elastic elements) with continuous coverage (from the crosspiece spanning the full width). This combination allows the system to achieve both sagging resistance through elastic deformation and continuity of support through the interconnected arrangement of members along the entire crosspiece length.
3Ease of manufacture
If elastic members are uniformly distributed along the crosspiece, then manufacturing simplicity is maintained, but sagging is not effectively limited in the central part where user weight is concentrated
Solution Approach 1:
The elastic members are positioned at specific locations along the crosspiece (between ends and middle) to provide targeted support in regions most prone to sagging. The non-uniform distribution of elastic members creates locally optimized support zones that address the specific stress patterns experienced by mattress supports, enhancing resistance to sagging where it occurs most frequently.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively limits sagging and maintains comfort by densifying elastic members in the central area, ensuring continuous support across the mattress width, improving user experience and reducing the likelihood of discomfort from flexing slats or discontinuous support.
Implementation Method 1
