Solution Overview

Problem

Existing bed frames do not provide a smooth swaying motion for relaxation and quality sleep while preventing longitudinal movement and minimizing noise and power consumption.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the bed frame allows side-to-side swaying motion, then relaxation and sleep quality are improved, but longitudinal stability deteriorates

Engineering Contradiction:

Improveswaying motionVSAvoidlongitudinal stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The bed frame is segmented into multiple functional components: rigid platform for support, flexible suspension cables for lateral motion, and longitudinal stabilizers for directional control. This segmentation allows each component to specialize in one function, enabling swaying motion while preventing longitudinal movement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the bed frame have different mechanical properties: the suspension cables are flexible to allow lateral swaying, while the longitudinal stabilizers are rigid to prevent forward-backward movement. This local differentiation of mechanical properties resolves the contradiction between allowing motion and maintaining stability.

Inventive Principle:

Principle #3Local quality

2Stability of the object's composition

If rigid connections are used to prevent longitudinal movement, then longitudinal stability is improved, but side-to-side swaying capability deteriorates

Engineering Contradiction:

Improvelongitudinal stabilityVSAvoidswaying capability

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The stabilizer mechanism exhibits asymmetric behavior: it resists longitudinal forces rigidly while allowing lateral motion through a different mechanical path. This asymmetric response to different directional forces enables simultaneous longitudinal stability and lateral swaying capability.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The stabilizer connection uses a dynamic mechanism (rod with slot and pivot) that adapts its constraint properties based on direction. The slot geometry allows lateral movement while blocking longitudinal movement, creating direction-dependent mechanical behavior that resolves the contradiction.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If traditional swaying mechanisms are used, then swaying motion is achieved, but noise and power consumption increase

Engineering Contradiction:

Improveswaying motionVSAvoidnoise

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent replaces traditional mechanical friction-based swaying mechanisms with a suspension cable system that uses tension and gravity. This substitution eliminates mechanical contact friction, significantly reducing noise generation while maintaining the desired swaying motion.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The suspension cables act as flexible elements that allow smooth, quiet motion. The flexibility of the cables enables gentle swaying without the rigid mechanical contacts that generate noise, creating a quiet operation environment.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A swayable bedframe that includes a mattress-supporting rigid platform having platform corners, a rigid platform support frame having a plurality of frame legs with the frame legs joined by corresponding beams, a platform support member attached proximal to each of the platform corners, a set of suspension cable connecting each of the platform support members to proximal to a first end each of the frame legs to allow the rigid platform to sway from side-to-side, a set of longitudinal stabilizers preventing movement of the platform in a longitudinal fore and aft direction while allowing side-to-side movement of the platform, a drive unit providing reciprocating force between the rigid frame and the platform, and a set of sway limiters ensuring that the mattress-supporting platform does not exceed a predetermined amount of movement relative the rigid platform support frame.
