Solution Overview
Problem
Current high-end mattresses with complex internal structures are difficult to disassemble, making them inconvenient for transportation and storage, and requiring the entire mattress to be replaced when individual components deteriorate.
Innovation Solution
An elastic pad with a bottom layer structure featuring upward protrusions allows for easy mounting and disassembly of elastic modules by inserting the protrusions into the modules, eliminating the need for additional rigid structures and enabling independent module replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-end mattresses use complicated internal structures to provide comfort, then comfort is improved, but disassembly difficulty increases and transportation convenience deteriorates
Solution Approach 1:
The mattress is divided into multiple independent elastic modules arranged in an array, each module containing individual elastic elements. This segmentation allows the mattress to maintain complex internal structures for comfort while enabling easy disassembly by removing individual modules or sections, resolving the contradiction between structural complexity and disassembly convenience.
2Reliability
If high-end mattresses use complicated internal structures, then comfort is improved, but the entire mattress must be replaced when components age, leading to waste
Solution Approach 1:
By segmenting the mattress into replaceable elastic modules, individual aged or damaged components can be removed and replaced without discarding the entire mattress. This extends the product lifecycle and reduces material waste while maintaining the complex internal structure needed for comfort.
Solution Approach 2:
The modular design enables selective replacement of aged elastic modules while retaining functional components. Used modules can be recovered, refurbished, or recycled separately, reducing overall waste and supporting sustainable product lifecycle management.
3Ease of manufacture
If elastic modules are mounted via chute, then mounting is achieved, but the structure becomes more complex and modules cannot be mounted independently
Solution Approach 1:
Instead of guiding modules into place through complex chute structures, the invention inverts the approach by providing upward protrusions from the bottom layer that directly engage with corresponding recesses in the elastic modules. This simplified inversion enables easy mounting while allowing independent placement of each module without requiring complex guiding structures.

AI summary
An elastic pad for furniture includes a mounting layer, a plurality of elastic modules, an elastic balance net and a flexible cover. A plurality of raised blocks are arranged on a top surface of the mounting layer. Each elastic module is nested on one of the raised blocks, where an outer diameter of the raised block is greater than or equal to an inner diameter of the elastic module at a corresponding height. This allows the elastic modules to be mounted independently of one another. For example, if an elastic module is damaged, it can be removed for repair, without removing other elastic modules.
