Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fans, including oscillating and cover-rotating types, face limitations in directing airflow to different directions, leading to reduced cooling efficiency and safety concerns due to unbalanced weight distribution in oscillating mechanisms, which results in reduced operating efficiency and shortened service life.
Innovation Solution
A fan with a concealed 360-degree oscillating mechanism, where a first driving motor connected to a pivot member and oscillating mechanism allows the blades to rotate and oscillate 360 degrees, distributing force evenly to prevent stress fatigue and enhance airflow efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional oscillating mechanisms are used to direct airflow to different directions, then airflow directionality is improved, but unbalanced weight distribution causes stress fatigue and reduced service life
Solution Approach 1:
The oscillating mechanism is segmented into multiple independent components: a first oscillating mechanism for horizontal oscillation and a second oscillating mechanism for vertical oscillation. Each mechanism operates independently with its own driving motor, allowing airflow to be directed in multiple directions (360-degree coverage) while distributing mechanical stress across separate structural paths, thereby preventing stress concentration and fatigue failure.
Solution Approach 2:
The patent employs counterweight mechanisms within each oscillating system to balance the weight distribution during oscillation. The counterweights offset the unbalanced forces generated by the rotating and oscillating components, ensuring that the main housing and supporting structure experience minimal net unbalanced forces, thus preventing stress fatigue and extending service life.
2Ease of operation
If conventional oscillating fans are used for manual orientation, then airflow direction can be adjusted, but safety risks arise from operator's hand touching metal blades
Solution Approach 1:
The patent replaces static manual orientation with dynamic automated oscillation control. Two independent oscillating mechanisms driven by electric motors automatically adjust the blade assembly's orientation in horizontal and vertical planes, providing 360-degree airflow coverage without requiring manual intervention near the rotating blades, thereby eliminating safety risks while maintaining ease of operation.
Solution Approach 2:
The oscillating mechanisms are equipped with control systems that enable automated operation. The fan can be controlled to oscillate in predetermined patterns or respond to remote commands, allowing the system to serve itself in terms of direction adjustment without human contact with dangerous moving parts.
3Productivity
If conventional fans produce linearly moved airflow, then simple blade rotation is sufficient, but cooling efficiency is reduced due to limited airflow coverage
Solution Approach 1:
The patent transitions from single-dimensional linear airflow to multi-dimensional airflow coverage by implementing two independent oscillating mechanisms. The first mechanism provides horizontal oscillation (adding one dimension of directional control), and the second mechanism provides vertical oscillation (adding another dimension). This creates three-dimensional airflow coverage, significantly expanding the effective cooling area and improving overall cooling efficiency.

AI summary
A fan with concealed 360-degree oscillating mechanism includes a main housing; a pivot member vertically, pivotally and turnably mounted in the housing; a first driving motor having a forward first rotary shaft and horizontally, pivotally and turnably mounted in the pivot member; an oscillating mechanism assembled between the first driving motor and a rear end face of the main housing, and having a first end driving an opposing second end to rotate eccentrically; and a set of blades fixedly connected to the first rotary shaft to locate in front of the main housing. With the first driving motor pivotally connected to the pivot member and eccentrically connected to the oscillating mechanism, the set of blades can be oscillated 360 degrees while being rotated by the first driving motor; and parts inside the main housing undertake force evenly to enable stable operation of the fan and reduced stress fatigue of the oscillating mechanism.
