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
Engineering 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
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.
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.
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
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.
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.
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
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.
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.
