Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing bed bases with lifting support portions for knees and back often have a profile with broken sides when raised, making it difficult for the mattress to conform to the body, leading to discomfort.

Innovation Solution

A bed base design featuring rigid panels connected by bendable longitudinal strips that allow for smooth curvature without articulated mechanical connections, ensuring a continuous profile in both raised and lowered positions, and incorporating elastic edge elements for a regular line appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If articulated mechanical connections are used to enable raising of support portions, then the support portions can be moved between lowered and raised positions, but the profile of the lying surface develops broken sides that prevent proper mattress conformance

Engineering Contradiction:

Improveability to raise support portionsVSAvoidprofile continuity of lying surface

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The support portions are divided into multiple rigid panels connected by bendable strips, allowing each panel to remain structurally intact while the overall structure achieves continuous curvature through the flexible connections between segments

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Bendable longitudinal strips (thin flexible elements) connect the rigid panels, enabling smooth curvature and continuous profile lines when the support portions are raised, eliminating the broken sides caused by rigid articulated connections

Inventive Principle:

Principle #30Flexible shells and thin films

2Strength

If thick beam-type elements are used to form the lying surface, then structural support is improved, but the moving mechanical parts create broken sides that disrupt the profile

Engineering Contradiction:

Improvestructural support of lying surfaceVSAvoidprofile regularity

Core Design Contradiction:

StrengthVSShape

Solution Approach 1:

The thick beam structure is segmented into multiple rigid panels that maintain structural strength, while the segmentation allows flexible connections to create smooth continuous curves without broken sides

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The lying surface combines rigid panels (for structural strength) with flexible bendable strips (for profile continuity), creating a composite structure that achieves both strength and smooth curved profiles

Inventive Principle:

Principle #40Composite materials

AI summary

The mattress has a bedding surface intended to support a body of a person. The bedding surface includes a central support portion (20) for supporting gluteal. A knee supporting portion and a back supporting portion are extended on both sides of the central portion. The knee supporting portion and the back supporting portion are formed of two series of rigid wooden panels (2) connected together and connected to the central portion by bendable longitudinal connection strips (3, 3A, 3B) that extend parallelly to a longitudinal line of the bedding surface.
