Solution Overview

Problem

Existing bed structures with metal sheet connections between beams and columns face issues such as increased transportation space requirements, potential gaps leading to noise and instability, and concentrated force bearing points that can lead to safety hazards.

Innovation Solution

A beam and column connecting structure that uses a plastic connector instead of a metal sheet, where the connector is inserted into an insertion hole in the column and the beam is inserted into the connector, providing a stable and compact connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a metal sheet is used to connect the beam and column, then the connection is achieved, but the beam takes up more space during transportation

Engineering Contradiction:

Improvetransportation spaceVSAvoidconnection stability

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The connector is inserted into an insertion hole within the column, and the beam is inserted into the connector, creating a nested structure where the beam end is received by the connector which is itself received by the column. This nesting eliminates the need for external metal sheets and reduces transportation space while maintaining connection stability.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Object-affected harmful factors

If a thick metal sheet is used for connection, then the connection is achieved, but a gap exists between the beam and column causing noise

Engineering Contradiction:

Improvenoise from frictionVSAvoidconnection structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The connector acts as an intermediary component between the beam and column. It includes a bottom wall that abuts against the inner side wall of the column and side walls that abut against the outer sidewalls of the beam, effectively filling the gap and eliminating friction-induced noise while maintaining a relatively simple structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If the beam is connected through a metal sheet, then the connection is achieved, but the force bearing point is concentrated causing instability

Engineering Contradiction:

Improveconnection stabilityVSAvoidforce distribution

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The connector is divided into multiple functional segments: a bottom wall that contacts the column's inner side wall, side walls that contact the beam's outer sidewalls, and a top opening for beam insertion. This segmentation distributes the force bearing across multiple contact surfaces rather than concentrating it at a single point, enhancing connection stability.

Inventive Principle:

Principle #1Segmentation

4Device complexity

If a metal sheet is used for connection, then the beam and column are connected, but the structure is not compact

Engineering Contradiction:

Improvestructure compactnessVSAvoidtransportation space

Core Design Contradiction:

Device complexityVSVolume of moving object

AI summary

A beam and column connecting structure, including an insertion hole on the column, a connector inserted into the insertion hole, and a beam having an end inserted into the connector and being in complete contact with an inner side wall of the connector. A flange is provided around a top side of the connector and abuts against an outer side wall of the column around the insertion hole. A connecting plate is provided inside the end of the beam. At least one screw passes through the column, a bottom wall of the connector, and the connecting plate to fix the column, connector and the beam together.
