Solution Overview

Problem

Existing fan designs lack innovative features for easy maintenance and air propulsion efficiency, with prior art devices not adequately addressing the need for a Break-Away/Easy Clean Non-Detachable Fan that can efficiently unfold blades for cleaning and maintain air movement over time.

Innovation Solution

A fan design incorporating a set of blades, a hub, hinges, latches, and latch studs that allow blades to unfold to a 90-degree angle for maintenance, while securely latching them to the hub for efficient air propulsion, including oscillating, box, ceiling, industrial, and outdoor AC unit fans, ensuring economical production and modern air movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If blades are permanently fixed to the hub, then structural strength is improved, but maintenance accessibility deteriorates

Engineering Contradiction:
Improvestructural strengthVSAvoidmaintenance accessibility
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The blade assembly is segmented into detachable components connected by hinges and latches, allowing the blades to be separated from the hub for maintenance while maintaining structural integrity during operation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The blade connection system transitions from static permanent fixation to dynamic detachable connection, enabling the blades to be in a fixed state during operation and a detachable state during maintenance

Inventive Principle:
Principle #15Dynamics

2Ease of repair

If blades are made detachable for maintenance, then ease of cleaning is improved, but device complexity increases

Engineering Contradiction:
Improveease of cleaningVSAvoiddevice complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The blade assembly is divided into separable parts with hinge joints and latch mechanisms, enabling easy detachment for cleaning while using simple, standardized connection components

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of making the entire blade assembly detachable, only the connection points are made detachable through latches, while the hinge provides permanent flexible connection, simplifying the overall structure

Inventive Principle:
Principle #13The other way round (Inversion)

3Ease of repair

If blades are hinged to the hub, then maintenance accessibility is improved, but reliability deteriorates

Engineering Contradiction:
Improvemaintenance accessibilityVSAvoidreliability
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The latch mechanism includes safety features and proper engagement designs that prevent accidental detachment, cushioning against potential reliability issues before they occur

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The hinge provides controlled flexibility allowing thermal expansion and contraction while maintaining secure connection, adapting to operational conditions without compromising reliability

Inventive Principle:
Principle #15Dynamics
