Plastic Spring Element Structure for Mattress Tilt Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spring elements for mattresses lack sufficient stability, especially against tilting, while also requiring high manufacturing costs and durability, which are not adequately met by current designs.
Innovation Solution
A spring element design featuring a symmetrical structure with struts connecting support parts and connecting sections to the base, allowing for wave-shaped deflection primarily through struts and connecting sections, with optional additional struts and rings for enhanced stability and production simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple spring element structure is used, then manufacturing costs are reduced, but stability against tilting deteriorates
Solution Approach 1:
The spring element is divided into modular components: a base, multiple support parts, struts connecting support parts, and connecting sections linking struts to the base. This segmentation allows for simple manufacturing of individual parts while achieving high stability through their geometric arrangement and interconnection, resolving the contradiction between manufacturing simplicity and tilting resistance.
2Stability of the object's composition
If support parts are connected via struts to the base, then stability against tilting is improved, but device complexity increases
Solution Approach 1:
Multiple functions are merged into single components: struts serve both as structural connectors and as part of the spring body forming wave-shaped courses; connecting sections integrate the linkage function directly into the base structure. This merging reduces the number of separate parts and simplifies manufacturing while maintaining the stable triangular geometric structure for tilting resistance.
3Ease of operation
If struts form wave-shaped courses around the central spring axis, then deflection behavior is improved, but manufacturing precision requirements increase
Solution Approach 1:
The struts are designed to form wave-shaped courses (curved paths) around the central spring axis instead of straight lines. This curvature allows the struts to deflect in a controlled manner during spring operation, improving the deflection behavior and load distribution while the modular construction keeps manufacturing precision requirements manageable.
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 design achieves high stability against tilting with low material costs and simplified production, allowing for efficient deflection without significant movement away from the central axis, maintaining effective support properties.
Implementation Method 1
a spring body (3) arranged between the base (1) and support parts (2)... the struts (4) together forming a wave-like course around the central spring axis (I)... in which the support parts (2) in particular do not move away from the central spring axis

AI summary
The element has a spring body (3) arranged between a base (1) and upper support parts (2). The two support parts lying adjacent to each other are connected with bars (4). The bars are connected with the base via a connecting section (5). The connecting section lies downwards than the support parts, which are connected with each other, in a spring direction in a release condition of the spring element. The bars include a corrugated curvature around a central spring axis (I). The element is integrally manufactured from plastic.
