Solution Overview

Problem

Existing fan designs with semicircular arc-shaped pivot points result in poor stability and limited adjustment of the fan head, affecting the air outlet angle and overall user experience.

Innovation Solution

A fan design featuring a hinge assembly with a first and second connection member that rotate relative to each other, connected to a support structure, allowing the fan head to adjust its air outlet angle and improve stability by eliminating the need for a semicircular pivot point, with additional features like limit members and a ring-shaped support structure for enhanced reliability and assembly efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a semicircular arc-shaped pivot point is used to rotate the fan head, then the fan head can rotate relative to the column, but the stability of the fan head becomes poor

Engineering Contradiction:
Improvefan head rotationVSAvoidfan head stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The hinge assembly is divided into multiple connection members (first connection member, second connection member, third connection member) that are hinge-connected to each other, allowing the fan head to rotate while maintaining stability through the segmented structure. Each connection member can rotate relative to the others, providing controlled movement rather than free rotation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hinge assembly employs a nested structure where connection members are arranged in sequence (first, second, third connection members) with each member nested within the rotation mechanism of the previous one, creating a compact multi-axis rotation system that maintains fan head stability while enabling adjustment.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of manufacture

If a semicircular arc-shaped pivot point is used, then the fan head can be connected to the column, but the appearance and reliability are compromised

Engineering Contradiction:
Improveconnection implementationVSAvoidconnection reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The hinge assembly provides dynamic adjustment capability through multiple hinge-connected members that can rotate relative to each other, allowing the fan head to be adjusted to different angles while maintaining a reliable connection. The dynamic nature of the hinge connections replaces the static semicircular pivot point.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If a semicircular arc-shaped pivot point is used, then the fan head can rotate, but the air outlet angle adjustment is limited

Engineering Contradiction:
Improvefan head rotationVSAvoidair outlet angle adjustment
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The hinge assembly enables rotation in multiple dimensions by arranging connection members in sequence, where the first connection member rotates relative to the column, the second connection member rotates relative to the first, and the third connection member rotates relative to the second. This multi-dimensional rotation capability significantly expands the air outlet angle adjustment range compared to a single-axis semicircular pivot.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A fan includes a column assembly, a fan head, a hinge assembly, and a support structure connected to the fan head and the column assembly. The hinge assembly includes a first connection member and a second connection member which are hinge-connected to each other. The first connection member is connected to the column assembly, and the second connection member is connected to the fan head. The fan head is configured to rotate around the support structure, and an axis around which the fan head rotates relative to the support structure coincides with an axis around which the first connection member and the second connection member rotate relative to each other.
