Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed stiffness mattress base is used, then the structure is simple and stable, but it cannot adapt to different weights and preferences for optimal lying comfort
Solution Approach 1:
The patent applies the dynamics principle by making the mattress base stiffness adjustable rather than fixed. The support elements incorporate adjustment mechanisms that allow the stiffness to be dynamically changed according to different users' weights and preferences, transforming a static structure into an adaptive system that can respond to varying operational conditions.
Solution Approach 2:
The patent implements parameter changes by modifying the stiffness parameter of the support elements through adjustable components. By changing the stiffness parameter, the mattress base can adapt to different users, and this parameter adjustment is achieved through mechanical means that modify the physical properties of the support structure.
2Adaptability or versatility
If adjustment mechanisms are added to modify deflection hardness, then adaptability improves, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies segmentation by dividing the adjustment function into separate, modular components. Each support element is equipped with its own adjustment mechanism, allowing independent adjustment of different sections of the mattress base. This modular approach simplifies manufacturing compared to a fully integrated system, as each segment can be produced and adjusted independently.
Solution Approach 2:
The patent implements self-service through user-adjustable mechanisms that allow end-users to modify the deflection hardness according to their needs without requiring professional intervention. The adjustment mechanisms are designed to be operated by users themselves, eliminating the need for complex installation procedures or specialized tools, thereby reducing manufacturing and service costs.
3Manufacturing precision
If complex adjustment mechanisms are used, then adjustment precision improves, but ease of operation decreases
Solution Approach 1:
The patent applies mechanics substitution by replacing complex mechanical adjustment systems with simpler mechanisms. Instead of using intricate gear systems or multiple linkage components, the invention employs direct-adjustment mechanisms that achieve precise stiffness modification through simpler mechanical means, reducing operational complexity while maintaining adjustment precision.

AI summary
The mattress has two longitudinal supports (1, 2) spaced apart from each other and running in a longitudinal direction of a bed. Support elements (3) are arranged transverse to the supports. A retaining unit (13) is attached to outer end regions of side parts (5, 6) of the support elements. A support surface (15) of the mattress forms top of the support elements. A flat spring shaped element (11) running along bridge elements (7) is attached to an area of connection of the bridge elements. The flat spring shaped element is tensioned with respect to the bridge elements by a tensioner (12).
