Method for customizing and assembling elastic cushion for user to sit and lie on
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high-end mattresses have complex internal structures that are not customizable, making them inconvenient for handling, storage, and maintenance, and users cannot adjust the softness and hardness, leading to waste when individual components age.
Innovation Solution
A method for customizing and assembling an elastic pad by acquiring top and bottom cover bodies, selecting elastic module and pad layers for desired softness and hardness, and connecting them with a side enclosure, allowing users to replace aged parts, enabling individual customization and extended use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-end mattresses have complex internal structures to improve comfort, then comfort performance is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The mattress is divided into multiple independent functional layers including support layer, comfort layer, and cover layer that can be separately assembled and disassembled. Each layer serves specific functions while maintaining independence, allowing users to handle and store individual layers rather than the entire complex structure.
Solution Approach 2:
The mattress structure transitions from a fixed integrated design to a dynamic modular configuration where layers can be adjusted, reconfigured, or removed based on user needs. This dynamic design maintains comfort performance while improving handling convenience through selective assembly and disassembly.
2Reliability
If high-end mattresses have complex internal structures to improve comfort, then comfort performance is improved, but ease of repair deteriorates
Solution Approach 1:
The mattress is segmented into replaceable functional layers with standardized interfaces. When one layer deteriorates, only that specific layer needs to be replaced rather than the entire mattress, significantly reducing maintenance costs and improving ease of repair while preserving the complex comfort-enhancing structure of other layers.
Solution Approach 2:
The design enables selective replacement of worn or damaged layers while retaining and reusing the remaining functional layers. This approach recovers value from non-deteriorated components and reduces waste, allowing users to maintain high comfort performance without replacing the entire mattress structure.
3Ease of manufacture
If conventional mattresses are of one-piece structure to simplify manufacturing, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The mattress is designed as modular segments with standardized connection interfaces that simplify manufacturing of individual components while enabling extensive customization through different combinations. Each layer can be manufactured independently using optimized processes, then assembled to create customized configurations.
Solution Approach 2:
The modular layers are designed with universal interfaces and standardized dimensions that allow the same components to be used across different mattress configurations and models. This universality maintains manufacturing simplicity while enabling users to customize their mattresses by selecting different layer combinations for various comfort and support needs.

AI summary
An elastic pad for furniture can be customized and assembled by a user. The elastic pad includes an outer cover, an elastic module layer and at least one elastic pad layer. A side enclosure of the outer cover is detachably connected with a top cover body, and the side enclosure is detachably connected with the bottom cover body. The elastic pad is configured to allow a user to select a desired type and/or a desired number of elastic module layers and elastic pad layers, and to further select the side enclosure based on a thickness of the elastic module layer and elastic pad layer, and assemble the top cover body, the bottom cover body, the selected side enclosure, and the selected elastic module layers and elastic pad layers together to obtain the elastic pad.
