Slatted Frame Bellows Support for Adjustable Hardness and Venting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slatted frames are complex, expensive, and lack the ability to regulate the hardness of individual slats, while also failing to address moisture issues in mattresses.
Innovation Solution
A slatted frame design where each plate supporting the mattress is equipped with a compressible bellows attached to the slats, allowing individual hardness regulation using elastic material, and featuring ventilation grooves for dehumidification and a frustoconical configuration for effective support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex kinematic coupling system with multiple bellows and pneumatic connections is used to support slats, then the support functionality is achieved, but the device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent extracts and eliminates the complex kinematic coupling system, pneumatic connections, and air distributor from the slatted frame design. Instead of using multiple interconnected bellows with pneumatic coupling, the invention uses simple individual bellows attached directly to each slat, removing the disturbing complex parts while retaining the essential support functionality.
Solution Approach 2:
The patent replaces expensive, complex pneumatic coupling systems with simple, inexpensive individual bellows that can be easily manufactured and replaced. Each bellows acts as an independent, simple component rather than part of a complex interconnected system, reducing both manufacturing cost and device complexity.
2Adaptability or versatility
If individual support bars are made adjustable for hardness regulation, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent achieves hardness regulation by changing the physical parameters of the bellows themselves - specifically using bellows made of elastic material with varying degrees of stiffness. By selecting bellows with different elastic properties, the hardness can be adjusted without any complex adjustment mechanisms, switches, or control systems.
Solution Approach 2:
The patent replaces complex mechanical adjustment systems with a simple material property-based solution. Instead of using mechanical mechanisms to adjust hardness, the invention uses the inherent elastic properties of the bellows material to provide different hardness levels, eliminating the need for complex adjustment mechanisms.
3Adaptability or versatility
If bellows are made compressible with elastic material for hardness regulation, then adaptability is improved, but the ability to provide stable support is reduced
Solution Approach 1:
The patent uses dynamic bellows made of elastic material that can compress and expand in response to load. The bellows provide stable support when compressed by the weight of the mattress and user, while maintaining the ability to adjust hardness through material selection. The elastic material naturally returns to its original shape, providing stable support while allowing for different hardness levels.
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 simplifies the slatted frame, allows for adjustable hardness of individual support plates, and effectively dehumidifies the mattress by using compressible bellows with elastic material and ventilation grooves.
Implementation Method 1
each plate (2-6) has a bellows (10) made of an elastic material fixed to the underside of each plate (2-6)
Implementation Method 2
each of the plates (2-6) is connected to the inside of the bellows (10) by means of an opening (11), which allows ventilation between the mattress and the surface of the plates (2-6)

AI summary
The slatted frame (1) has a transverse strip connected to a plate carrier that is provided with multiple plates (2 to 6) as an intermediate piece between the strip and a mattress. Each plate is carried by a bellow, which is compressed and fixed on the strip, where the plates are aligned in a longitudinal direction and transversely to the frame. A groove (12) is formed on the surface of each plate, where the groove is opened in an opening (11), which is used for connecting the plate inside the bellow.
