Solution Overview
Problem
Traditional mattress foundations often compromise on stability when assembled by consumers, as quick and easy assembly typically requires pre-assembling parts, increasing packaging complexity and shipping costs, while sacrificing stability, and may result in a swaying frame shape during movement or relocation.
Innovation Solution
A mattress foundation kit comprising side rails, end rails, and slats with varying lengths and angles, along with corner stabilizers and flexible connections, allows for easy assembly and increased stability by overlapping rail sections and using angle-adjustable slats, which are packaged in a parallel orientation for shipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the foundation is pre-assembled to ensure stability, then stability is improved, but packaging complexity and shipping costs increase
Solution Approach 1:
The foundation is divided into separate modular components (side rails, end rails, slats, corner blocks) that can be packaged separately and assembled by the consumer. This segmentation allows each component to be optimized for compact packaging while maintaining the ability to form a stable complete structure when assembled.
Solution Approach 2:
Corner blocks are pre-configured with recesses and fastening mechanisms that guide the assembly process. The rails are designed with predetermined positioning features that align during assembly, reducing the need for complex packaging while ensuring proper assembly sequence and foundation stability.
2Stability of the object's composition
If the foundation is pre-assembled to ensure stability, then stability is improved, but assembly time and tools required increase
Solution Approach 1:
The corner blocks are designed to self-align and self-secure the rails through recesses that guide placement and built-in fastening mechanisms that automatically secure components together. This self-service design eliminates the need for complex assembly tools and reduces assembly time while maintaining stability.
Solution Approach 2:
Corner blocks serve as intermediary components that mediate the connection between side rails and end rails. These corner blocks provide a simplified interface that guides the assembly process and secures the framework, reducing the complexity and time required for direct rail-to-rail connections.
3Ease of operation
If fewer tools are used for assembly to reduce complexity, then ease of assembly is improved, but foundation stability may be compromised
Solution Approach 1:
The corner blocks incorporate built-in fastening mechanisms that automatically secure the rails without requiring external tools. The recesses and positioning features guide the assembly process while the integrated fastening system ensures stable connections, achieving both ease of assembly and foundation stability.
Solution Approach 2:
The corner blocks merge multiple functions into a single component: they provide structural connection points, guide rail positioning, and incorporate fastening mechanisms. This consolidation eliminates the need for separate tools while ensuring stable connections through the integrated design.
4Reliability
If slats are positioned non-perpendicularly at angles of 25° to 35°, then mattress support is improved, but assembly precision requirements increase
Solution Approach 1:
The slat positioning features are designed with local quality variations at specific locations along the rails. The rails include positioning features at predetermined intervals that guide slats at the required 25° to 35° angles, ensuring proper orientation without requiring high precision throughout the entire assembly process.
Solution Approach 2:
The rails are pre-configured with positioning features and guide elements that establish the correct slat angles before slat installation. This preliminary preparation ensures that slats are positioned at the precise 25° to 35° angles required for optimal mattress support, reducing the precision requirements during the actual slat installation step.
