Solution Overview

Problem

Existing elastic mattresses have complex assemblies, poor stability, and occupy large storage space due to their non-detachable, integrated structure.

Innovation Solution

The elastic unit and module group designs feature detachable elastic modules with flexible sleeves and bases, allowing for orderly arrangement and sleeving, enabling rapid assembly, improved stability, and easy disassembly for reduced storage space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the elastic mattress uses an integrated non-detachable structure, then the assembly is complete and stable, but it occupies large storage space and is inconvenient to carry

Engineering Contradiction:
Improvestorage spaceVSAvoidstructural stability
Core Design Contradiction:
Volume of moving objectVSStability of the object's composition

Solution Approach 1:

The elastic mattress is divided into multiple detachable elastic modules, each comprising a base, elastic elements, and connecting structures. These modules can be separated for storage and transportation, reducing the volume occupied during storage while maintaining structural integrity during use through the connecting structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The elastic modules are designed with sleeve structures that allow them to be nested or stacked together when detached. The openings at the bottoms of modules enable one module to be inserted into another, creating a compact nested configuration for storage that significantly reduces the space required.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Stability of the object's composition

If the elastic mattress uses an integrated structure, then the assembly is complete, but it has complex assemblies and poor stability

Engineering Contradiction:
Improveassembly stabilityVSAvoidassembly complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The mattress is segmented into standardized modules with uniform connecting structures. Each module contains complete functional elements (base, elastic elements, sleeves), allowing independent assembly without complex inter-module dependencies, thereby simplifying the overall assembly process while maintaining stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple functional components (base, elastic elements, sleeves, connecting structures) are merged into integrated elastic modules. This consolidation reduces the number of separate assembly steps and creates stable self-contained units that are easier to assemble than separate integrated components.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If the elastic modules are detachably disposed with openings for sleeving, then the assembly and disassembly is rapid and storage space is reduced, but the structural complexity increases

Engineering Contradiction:
Improveassembly speedVSAvoidstructural complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The sleeve structures with openings enable elastic modules to be nested together through a simple insert-and-lock mechanism. This nested design allows rapid assembly by simply sliding modules into position and quick disassembly by reversing the process, without requiring complex fastening mechanisms.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The sleeves act as flexible connecting structures that provide both structural support and ease of assembly. The flexible nature of the sleeves allows them to accommodate slight misalignments during assembly while maintaining a stable connection, reducing the need for precision alignment mechanisms.

Inventive Principle:
Principle #30Flexible shells and thin films
