Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sleeping or reclining furniture with slatted frames has a bulky and inflexible base suspension that is difficult to handle and adapt to different sleeping habits and purposes, limiting its versatility and adjustability.
Innovation Solution
A modular, frameless base suspension system with flexible side strands and adjustable suspension elements that can be rolled up for easy transport, allowing individual customization of the distance between slats and incorporation of movable bearing means for enhanced comfort and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid frame with spring strips is used as base suspension, then the structural stability is improved, but the ease of handling and transport deteriorates due to bulky structure
Solution Approach 1:
The base suspension is divided into separate components: side strands (23) that can be independently folded, bearing means (21) that can be detached, and slats (16) that are removable. This segmentation allows the frameless base suspension to be collapsed and stored compactly while maintaining structural stability during use.
Solution Approach 2:
The side strands (23) are designed as flexible, foldable elements that can dynamically transition between an extended configuration during use (providing structural support) and a collapsed configuration for storage and transport. This dynamic adaptability resolves the contradiction between stability during use and ease of handling during transport.
2Stability of the object's composition
If bearing means are fixed to side strands, then the base suspension stability is improved, but the adaptability to different sleeping habits deteriorates
Solution Approach 1:
The bearing means (21) are designed with movable or oscillating capabilities, allowing them to dynamically adjust to different loading conditions and sleeping positions. This enables the base suspension to adapt to various sleeping habits while maintaining stability through the resilient support provided by the bearing means.
Solution Approach 2:
The bearing means (21) can be positioned at different locations along the side strands (23), and their spacing can be adjusted to change the characteristics of the base suspension. This parameter adjustment capability allows adaptation to different sleeping habits and requirements while maintaining structural stability.
3Stability of the object's composition
If a frame structure is used for base suspension, then the support stability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The traditional rigid frame structure is completely removed from the base suspension design. Instead, support stability is achieved through the interaction of flexible side strands (23), bearing means (21), and slats (16), eliminating the complexity of frame construction, corners, and joints while maintaining adequate support stability.
Solution Approach 2:
The side strands (23) function as flexible structural elements that replace the rigid frame. These flexible elements provide the necessary support and stability through their tension and resilience properties, simplifying the overall structure while eliminating the need for complex frame assemblies.
4Adaptability or versatility
If the number of slats is increased to improve support distribution, then the comfort is improved, but the handling difficulty and storage space requirements increase
Solution Approach 1:
The slats (16) are designed as separate, removable components that can be individually adjusted or removed. This allows the number of slats to be optimized for support distribution while maintaining ease of handling, as the slats can be detached and stored separately when not in use, unlike integrated frame structures.
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 enables easy handling and adaptation of the furniture to various uses and sleeping cultures, providing improved comfort and flexibility through adjustable suspension and movable bearing elements, allowing for customizable support and vibration features.
Implementation Method 1
The base suspension has several strips 16 running transversely to the longitudinal direction 15 of the bed 10, which may optionally be spring strips
Implementation Method 2
The side strands 23 are formed from flat belts in the exemplary embodiment shown. The flat sides of the belts of both side strands 23 lie in a horizontal plane in the flat base spring 13 shown here

AI summary
Beds (10) usually have a supporting spring system (13) for a mattress (14) which has a rigid frame. It is required that such supporting spring systems (13) are adapted to the bed (10), in particular to the bed frame (11). Therefore, an individual supporting spring system (13) is required for each bed (10). Moreover, the supporting spring system (13) having a rigid frame is bulky and thus difficult to transport. The invention provides a bed (10) having a frameless flexible supporting spring system (13). The flexible supporting spring system (13) is supported by a carrying frame (12) or directly by the bed frame (11). The flexible supporting spring system (13) can be rolled and is thus easy to transport. In particular, the flexible supporting spring system (13) allows for the use with different beds (10) and for individual adaptation to different sleeping habits.
