Engineering Contradiction Analysis
1Length of moving object
If existing assemblable household functional pads use single-layer elastic unit structures connected by fasteners or compression, then the structure achieves flexibility in assembly and disassembly, but the height requirement cannot be met
Solution Approach 1:
The elastic unit structure is divided into two independent layers: an upper spring module and a lower spring module. Each layer can be assembled and disassembled independently, allowing the height to be increased by stacking multiple layers while maintaining the flexibility of assembly and disassembly through modular design
Solution Approach 2:
The design transitions from a single-layer structure to a multi-layer vertical stacking configuration. By adding the height dimension through layer stacking, the overall height requirement is met while each individual layer maintains its assembly flexibility through the detachable connection mechanism
2Adaptability or versatility
If the functional pad is designed with fixed single-layer configuration, then the structure is simple, but it cannot adapt to different height requirements of customers
Solution Approach 1:
The functional pad design becomes dynamic and adjustable by allowing customers to assemble one or two layers according to their height requirements. The detachable connection mechanism enables the configuration to change from single-layer to double-layer, providing adaptability while keeping the base design relatively simple
Solution Approach 2:
The same modular elastic unit structure serves multiple functions: it can be used as a single layer for lower height requirements or stacked as two layers for higher height requirements. This universal design allows one component type to fulfill multiple height configuration needs

AI summary
A double-layer elastic unit structure includes a lower spring module and an upper spring module. The lower spring module includes lower spring members, and the upper spring module includes upper spring members. An insertion member is disposed on one spring member, and the other spring member includes an interface, and the insertion member and the interface form a detachable connection. The upper spring module includes a third connecting member(s) used for a pairwise connection between the upper spring members. The third connecting member(s) is disposed on ends of the upper spring members away, or the upper spring members are dependent and are not connected pairwise. The lower spring module includes a base, and the lower spring members are disposed on the base. The base is configured to be assembled and disassembled to an adjacent base.
