Modular Elastic Spring Assembly for Disassemblable Mattress Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional high-grade mattresses have complex internal structures that cannot be disassembled, leading to inconvenience during relocation and storage, poor adjustability in firmness, and limited universality in size and model adaptation.
Innovation Solution
An elastic module comprising upper and lower pre-compression springs connected by buckles and connection modules, allowing for detachable assembly and adjustment of firmness levels, and flexible geometric configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mattresses use complex internal structures to improve comfort, then comfort is improved, but the mattresses become integrated and cannot be disassembled, leading to inconvenience during relocation and storage
Solution Approach 1:
The mattress is divided into multiple independent elastic units, each containing springs and connection modules. These units can be detached and reconfigured, allowing the mattress to be disassembled for easy relocation and storage while maintaining the complex internal structure within each unit for comfort.
2Ease of operation
If mattresses use integrated structures to improve comfort, then comfort is improved, but the mattresses cannot be disassembled, causing waste when components age
Solution Approach 1:
The mattress is segmented into independent elastic units with detachable connections. When components age, only the specific elastic unit needing maintenance can be removed and replaced, enabling targeted maintenance and avoiding the need to discard the entire mattress.
Solution Approach 2:
The detachable design allows individual elastic units to be replaced independently. Old or worn units can be discarded and recovered separately while retaining functional units, reducing waste and extending the overall mattress lifespan.
3Adaptability or versatility
If mattresses use one-piece structures to simplify design, then manufacturing is simplified, but users cannot adjust firmness levels
Solution Approach 1:
The mattress is divided into multiple elastic units that can be independently configured. Users can adjust firmness by selecting different combinations of units or modifying the spring configurations within units, providing firmness adjustability while maintaining relatively simple manufacturing processes.
4Adaptability or versatility
If mattresses are assembled to adapt to bed frame sizes to improve fit, then size adaptation is improved, but universality in size and model is poor
Solution Approach 1:
The mattress is segmented into standardized elastic units with uniform connection interfaces. These modules can be assembled in different configurations to adapt to various bed frame sizes and models, improving universality while maintaining simple assembly structures through standardized connections.
