Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The fully welded base plate in existing rotary chairs results in a large packaging volume and higher production and sales costs due to increased factory costs.

Innovation Solution

A detachable base plate structure comprising a bottom ring, supporting rods, rotating shaft tray, rotating shaft, rotating shaft connector, and chair seat connecting steel plate, allowing the rotary chair base to be disassembled into separate parts for reduced packaging and manufacturing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a fully welded base plate structure is used, then the product structure is simple and strong, but the packaging volume becomes extremely large and the production cost increases

Engineering Contradiction:

Improvebase plate strengthVSAvoidpackaging volume

Core Design Contradiction:

StrengthVSVolume of moving object

Solution Approach 1:

The base plate is divided into multiple detachable components including a bottom ring, supporting rods, a rotating shaft tray, a rotating shaft, a rotating shaft connector, and a chair seat connecting steel plate. These segmented parts can be assembled and disassembled, reducing packaging volume while maintaining structural integrity through proper connection design.

Inventive Principle:

Principle #1Segmentation

2Strength

If a fully welded base plate structure is used, then the product structure is simple and strong, but the factory cost and sales price become extremely high

Engineering Contradiction:

Improvebase plate strengthVSAvoidproduction cost

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

3Volume of moving object

If the base plate is disassembled into separate parts, then the packaging volume and production cost are reduced, but the product stability may be compromised

Engineering Contradiction:

Improvepackaging volumeVSAvoidproduct stability

Core Design Contradiction:

Volume of moving objectVSStability of the object's composition

Solution Approach 1:

The supporting rods are reinforced with strengthening ribs that are formed in advance during manufacturing. This preliminary reinforcement ensures that when the detachable components are assembled, the base plate maintains sufficient stability and strength, eliminating concerns about structural weakness from disassembly.

AI summary

The present disclosure provides a highly steady rotary chair, and relates to the technical field of rotary chairs, which solves the technical problems that in the rotary chair in the prior art, a fully-welded base plate causes a product to have an extremely large packaging volume and higher production and sales cost. The highly steady rotary chair includes a rotary chair body and a rotary chair base. The rotary chair base includes a bottom ring, a supporting rod, a rotating shaft tray, a rotating shaft, a rotating shaft connector, and a chair seat connecting steel plate which are detachably connected in sequence from bottom to top; and the rotary chair body and the rotary chair base are detachably connected through the chair seat connecting steel plate. The present disclosure is used to provide the highly steady rotary chair with a detachable base plate and has the advantages of reducing the packaging cost and improving the product loading capacity.
