Solution Overview

Problem

Current beds with convenient assembly and disassembly lack a stable connection structure, resulting in an inferior comfort experience due to insufficient stability.

Innovation Solution

A bedstead design featuring a first connecting plate with a second connecting plate, supported by a first support leg with a connection mount, mounting holes, and a limiting screw system, including a conical limiting sleeve and slots, which provides a stable and secure connection while allowing for easy assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the bedstead uses a simple connection structure for easy assembly and disassembly, then the ease of operation is improved, but the stability and strength of the connection deteriorates

Engineering Contradiction:
Improveease of assembly and disassemblyVSAvoidstability of connection structure
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The connection structure is divided into multiple functional components: connecting plates with limiting slots for positioning, support legs with connection mounts for attachment, mounting holes for fastening, and limiting screws for securing. This segmentation allows each component to perform its specific function while working together to achieve both easy assembly and stable connection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection mount acts as an intermediary element between the connecting plates and support legs. It provides a standardized interface that facilitates easy assembly through simple alignment and fastening, while simultaneously ensuring stable connection through the limiting screw mechanism that prevents relative movement.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the bedstead uses a complex connection structure for high stability, then the stability is improved, but the ease of assembly and disassembly deteriorates

Engineering Contradiction:
Improvestability of connection structureVSAvoidease of assembly and disassembly
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The limiting slots are pre-formed on the connecting plates and the connection mounts are pre-equipped with mounting holes and limiting screw holes. This preliminary preparation of the connection structure allows for rapid assembly by simply aligning the components and inserting the limiting screws, eliminating the need for complex assembly procedures while maintaining high stability.

Inventive Principle:
Principle #10Preliminary action

3Strength

If the bedstead uses multiple connection components for stable splicing, then the strength is improved, but the device complexity increases

Engineering Contradiction:
Improvestrength of connectionVSAvoidcomplexity of connection structure
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The connection mount serves multiple functions: it provides mounting holes for fastening, limiting screw holes for securing, and a structural interface for connecting support legs to connecting plates. This multi-functionality reduces the need for separate components, thereby increasing connection strength while minimizing overall structural complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
