Intermediate Bed Suspension for Tunable Support and Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beds with spring bases face limitations in customizing the elasticity and vibrational characteristics to individual user needs, as the spring systems react as a unit and lack flexibility in adapting to different body shapes and weights.
Innovation Solution
Incorporating an intermediate spring system between the spring base and mattress, with varying elasticity and adjustable components, such as a cushion core and cover, to enhance lying comfort by allowing separate tuning of the support force and vibration behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional spring base is used, then the structure is simple and manufacturing is easy, but the lying comfort and adaptability to individual needs are limited
Solution Approach 1:
The spring base is divided into multiple independent spring layers (first spring layer, second spring layer, third spring layer) with different characteristics. Each layer can be independently designed and adjusted to provide different support characteristics, enabling individual adaptation while maintaining manageable structural complexity through modular design
Solution Approach 2:
Different spring layers are assigned different local qualities - the first spring layer provides coarse support, the second provides medium support, and the third provides fine support. This local differentiation allows the system to adapt to various body regions and individual needs while keeping each layer's design relatively simple
2Adaptability or versatility
If double-layer spring core layers are used, then the lying comfort is improved, but the freedom of movement of individual spring layers is limited and they react as a unit
Solution Approach 1:
The spring core is segmented into three separate layers instead of two, with each layer having independent movement capability. The first spring layer, second spring layer, and third spring layer can deform independently in response to body weight and position, providing enhanced elasticity adjustment while maintaining freedom of movement through this finer segmentation
Solution Approach 2:
Each spring layer is designed to dynamically respond to applied forces independently. The springs in each layer can compress, extend, and deform based on the specific load distribution, allowing the system to adapt dynamically to different sleeping positions and body types while maintaining individual layer mobility
3Stability of the object's composition
If the spring base is designed as an integrated bed frame, then the structure is compact, but the vibrational character differs significantly from separately designed spring systems
Solution Approach 1:
The integrated bed frame incorporates segmented spring layers that can vibrate independently. Each spring layer acts as a separate vibrational element, allowing the system to exhibit rich vibrational characteristics while maintaining the compactness of an integrated structure. The multiple layers create different vibrational modes and frequencies that can be tuned for comfort
4Adaptability or versatility
If mattress pad resilience is adjusted, then the support force can be customized, but the degree of customization is limited
Solution Approach 1:
Instead of relying solely on mattress pad adjustment, the spring support system itself is segmented into three adjustable layers. Each layer can be independently configured with different spring constants, densities, and thicknesses, providing much greater customization capability. This segmentation allows adjustment at the source of support rather than just at the mattress pad level
Solution Approach 2:
The system allows customization through parameter changes in multiple spring layers rather than relying on a single mattress pad. Each spring layer can have different parameters (spring constant, wire diameter, coil spacing, layer thickness) adjusted to achieve the desired support characteristics, providing extensive customization without requiring complex active adjustment mechanisms

AI summary
The bed (10) has an intermediate suspension (14) arranged between an under suspension (12) and a lying mattress (16). The intermediate suspension is provided with a pad core, a pad core overlay and a cover. Elastic/supporting force of the pad core is adjusted over length and/or width of the intermediate suspension. Free-running edges (18) are formed at two sides and two transverse sides of a frame i.e. timber frame, of the under suspension. The free-running edges are made from one of foam, latex and knitted fabric.
