Solution Overview
Problem
Existing mattress customization methods fail to accurately account for three-dimensional body profiles and weight distribution, leading to improper posture and discomfort due to uneven weight distribution and neglect of concave surfaces.
Innovation Solution
A method and system that utilize a 3D image of a user's body to create a three-dimensional model, dividing it into sections to determine downward pressure and adjust mattress parameters such as hoop assembly width/thickness and alignment structure cut-outs based on specific body areas, ensuring anatomical support and proper posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a two dimensional profile is used for mattress customization, then the manufacturing process is simpler, but the accuracy of weight distribution and surface pressure estimation is insufficient
Solution Approach 1:
The patent transitions from two-dimensional body profiles to three-dimensional body scanning and modeling. The system captures 3D images of the user's body, creates a 3D model, and divides it into multiple sections to accurately represent weight distribution and surface pressures across the body surface, thereby resolving the limitation of 2D profiles in capturing complex body topography.
Solution Approach 2:
The patent applies local quality by determining specific mattress parameters for different body sections. Each section of the 3D body model is analyzed independently to determine local weight distribution and surface pressure, which then informs customized mattress parameters (such as foam density, coil gauge, or layer thickness) for corresponding regions of the mattress, allowing tailored support for shoulders, hips, back, and other areas.
2Productivity
If average body profile is used for mattress manufacturing, then production efficiency is higher, but anatomical support for individual users is improper
Solution Approach 1:
The patent performs preliminary action by conducting 3D body scanning and analysis before mattress manufacturing. The system captures the user's body profile, creates a 3D model, calculates weight distribution and surface pressures in advance, and determines customized mattress parameters prior to production. This allows the mattress to be manufactured with precise anatomical specifications tailored to each user, rather than using generic average profiles.
Solution Approach 2:
The patent utilizes parameter changes by adjusting multiple mattress parameters based on individual body measurements. These parameters include foam density, coil gauge and spacing, layer thickness, firmness levels, and support zone dimensions. The system dynamically modifies these parameters according to the user's specific body topology, weight distribution, and pressure points, enabling personalized anatomical support while maintaining production efficiency through automated parameter calculation.
3Measurement precision
If 3D body modeling and sectioning is implemented, then weight distribution and surface pressure are accurately determined, but the system complexity increases
Solution Approach 1:
The patent replaces complex mechanical measurement systems with optical and computational methods. Instead of using physical pressure sensors or manual measurement devices, the system employs 3D imaging technology (such as structured light scanning or photogrammetry) to capture body surface geometry. Computational algorithms then process the 3D model to calculate weight distribution and surface pressures, substituting mechanical complexity with optical sensing and digital computation.
Solution Approach 2:
The patent uses copying by creating a digital 3D replica of the user's body. The 3D scanning process generates a virtual model that accurately represents the user's body topology, which can be manipulated, measured, and analyzed without physical contact. This digital copy allows for repeated analysis and parameter calculation without requiring additional physical measurement devices or direct interaction with the user's body.

AI summary
A method for customizing a mattress includes acquiring a three dimensional image of a body of a user and preparing, by a processor, a three dimensional model of the body of the user using the three-dimensional image. The method also includes dividing, by the processor, the three dimensional model into a plurality of sections arranged parallel to each other and arrayed along a height of the three dimensional model, and determining a downward pressure to be exerted by each of the plurality of sections on the mattress. The method further includes determining, by the processor, one or more parameters associated with at least one portion of the mattress adapted to be arranged underneath an associated section when person lies on the mattress based on the determined downward pressure or topography.
