Solution Overview

Problem

Existing beds with wire grid decks lack direct support under the user, suffer from rail migration due to single-directional support, and have structural rigidity issues.

Innovation Solution

A bed with a rigid deck supported by cross members and slots that provide bidirectional support to bed rails, preventing migration and enhancing structural rigidity through angle members and slots for longitudinal support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If wire grid decks are supported by perimeter frames only, then the bed structure is simpler, but the structural rigidity is insufficient

Engineering Contradiction:

Improvebed structureVSAvoidstructural rigidity

Core Design Contradiction:

Device complexityVSStrength

Solution Approach 1:

The bed frame is divided into perimeter frames and internal cross members, creating a segmented structure that distributes load and enhances rigidity without requiring complete perimeter support throughout the entire bed surface

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Cross members are added in the longitudinal direction to complement the perimeter frames, transforming the support system from a two-dimensional perimeter structure to a three-dimensional grid-like support network that provides superior structural rigidity

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Device complexity

If bed rails are supported in a single direction by wire grid segments, then the device complexity is reduced, but rail migration occurs

Engineering Contradiction:

Improvesupport mechanismVSAvoidrail position

Core Design Contradiction:

Device complexityVSStability of the object's composition

Solution Approach 1:

Instead of providing full bidirectional support along the entire length of the rails, slots are provided only at specific locations (at the ends or at intervals) where rail position control is most critical, achieving adequate stabilization with minimal additional complexity

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

Slots are introduced as intermediary elements between the cross members and the bed rails, providing a simple mechanical interface that enables bidirectional position control while maintaining ease of assembly and adjustment

Inventive Principle:

Principle #24Intermediary (Mediator)

3Stability of the object's composition

If cross members with slots are added to provide bidirectional support, then rail position stability is improved, but the device complexity increases

Engineering Contradiction:

Improverail positionVSAvoidsupport structure

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The support function and the position-control function are merged into a single integrated component (the slot in the cross member), which simultaneously provides structural support and prevents rail migration, eliminating the need for separate mechanisms

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The present invention relates to a bed having a rigid deck supported over the base. Four sections can be provided, with three of the sections comprising rigid grids that lie in respective planes. The sections can be coplanar when the deck is in a flat position. Several cross members can be provided to support the deck sections. Holders, which can be comprised of slots that are formed in the cross members, provide bidirectional support to side rails. In this regard, the bed rails can be removably positioned within the slots to maintain the position of the bed rails and eliminate rail migration.
