Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing modular mattresses are designed based on general anthropometric knowledge and known morphotypes, then the mattress can be assembled to form a sleep surface, but the mattress lacks flexibility and precision to adapt the sleep surface to one mattress user specifically
Solution Approach 1:
The mattress is divided into multiple independent modules, each with potentially different deformability characteristics. This segmentation allows the sleep surface to be customized by selecting and arranging specific modules to match individual user anthropometry, directly resolving the contradiction between adaptability and complexity.
Solution Approach 2:
Different zones of the mattress are assigned different deformability properties tailored to specific body regions. This local differentiation enables precise adaptation to individual user characteristics while maintaining overall mattress functionality, addressing the need for user-specific customization without requiring complete redesign.
2Manufacturing precision
If the sleep surface has uniform deformability, then the mattress structure is simple, but it cannot provide optimized contact pressure distribution for individual body weight distribution and morphology
Solution Approach 1:
The mattress employs zones with different deformability characteristics matched to specific body regions and user morphology. This local customization optimizes contact pressure distribution across the sleep surface, achieving manufacturing precision in pressure management while the modular approach keeps the overall system manageable.
Solution Approach 2:
The deformability parameter of different mattress zones is varied according to user-specific requirements. By changing this physical parameter across different modules, the system achieves optimized contact pressure distribution without requiring completely complex structural designs.
3Reliability
If the mattress is designed for general use, then it can accommodate various users, but it fails to provide optimized body posture support and minimized body posture variation for each user
Solution Approach 1:
The mattress is segmented into modules that can be configured to provide reliable body posture support for each user. By dividing the system into adjustable units, it achieves both user-specific customization and consistent posture support performance.
Solution Approach 2:
The modular mattress system serves multiple users with different anthropometric characteristics through reconfiguration of the same module set. This universality allows the mattress to adapt to various users while maintaining optimized body posture support for each individual.

AI summary
A modular multi-zone mattress and related method of design for which a plurality of mattress modules are adjoined to define a sleep surface having a variable deformability. A number of the mattress modules and a deformability of each mattress module are tailored to a unique body shape and weight distribution of a mattress user to provide at least one of an optimized body posture and an optimized contact pressure distribution over the sleep surface. Pressure factors include a weight and a morphologic profile of the mattress user, and optionally, a sleep position of the mattress user.
