Pre-Compressed Spring Module for Body-Conforming Mattress Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elastic mattresses fail to conform to the human body's curve due to interconnected springs that distribute stress uniformly, lacking the ability to adjust stress distribution based on posture, resulting in discomfort and inadequate ergonomic support.
Innovation Solution
An elastic module comprising pre-compressed springs connected through connecting members and lapping members, allowing independent stress adjustment and conforming to body curves by forming rows of connected springs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If springs are connected together through a connecting base to form a whole structure, then the mattress can withstand greater pressure, but stress applied to a local portion will drive surrounding springs around, preventing the mattress from conforming to the human body curve
Solution Approach 1:
The patent divides the spring system into independent pocket springs that are not mechanically connected to each other. Each spring is individually enclosed in a fabric pocket, allowing them to respond independently to applied stress without influencing surrounding springs. This segmentation resolves the contradiction by maintaining pressure withstanding capability through high spring density while eliminating stress coupling that prevents body contouring.
Solution Approach 2:
The patent implements local quality by allowing each spring to independently adjust its compression based on local body pressure. The varying compression rates across different body regions (higher pressure on hips/shoulders, lower on waist) are accommodated because each spring responds only to its local conditions. This enables the mattress to conform to the human body curve while maintaining overall structural strength through uniform spring distribution and density.
2Ease of manufacture
If connecting members are used to connect pre-compressed springs, then the springs can be assembled into rows and connected between rows, but the structure becomes more complex
Solution Approach 1:
The patent merges the functions of connection and support by integrating connecting members into the same structural plane as the spring support surface. The connecting members are positioned to align with spring centers, combining the functions of mechanical connection and structural support. This merging simplifies the overall structure compared to separate connection systems, enabling easy assembly into rows and between rows while maintaining relatively simple construction.

AI summary
The present disclosure discloses an elastic module, it comprises a plurality of pre-compressed springs, the pre-compressed springs contact or approach, a middle part of a pre-compressed spring is disposed with one of one or more connecting members, it further comprises one or more lapping members, the pre-compressed springs are connected to the one or more lapping members through the one or more connecting members, and the one or more lapping members enable the plurality of pre-compressed springs to be connected in series to form rows and connect the pre-compressed springs in two adjacent ones of the rows together. The elastic mattress adjusts a stress scope applied to springs according to a posture of human body on the elastic mattress to conform to a curve of the human body when being used in the elastic mattress, so that the elastic mattress can conform to ergonomic requirements to be softer and more comfortable while being subjected to greater stress.
