Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fans lack the ability to dynamically adjust blade angles and air flow dynamics in real-time based on environmental and user preferences, leading to inefficient air circulation, temperature modulation, and air purification, particularly in rooms with low ceiling heights and varying occupancy.
Innovation Solution
A fan system with intelligent computing capabilities and sensor-based control that autonomously adjusts blade angles and air flow dynamics using a BLDC motor, integrated sensors, and mechanical assemblies to optimize air fluid dynamics and climate conditions based on real-time environmental and user-specific parameters, incorporating HEPA and UV filtration for comprehensive air purification and temperature modulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If blade angles are adjusted manually using knobs or joineries, then air throw efficiency can be optimized, but the adjustment process becomes labour intensive and impractical
Solution Approach 1:
The fan system automatically adjusts its own blade angles using sensors to detect occupancy and environmental conditions, eliminating the need for manual intervention. The compute unit processes sensor data and autonomously controls the blade angle mechanism to optimize air throw based on real-time conditions.
Solution Approach 2:
The system incorporates sensors that continuously monitor room occupancy, temperature, and air quality, feeding this data back to the compute unit which then adjusts blade angles accordingly. This closed-loop feedback mechanism ensures optimal performance without manual adjustment.
2Productivity
If rotational speed of the fan is increased to enhance air throw volume, then air circulation improves, but noise generated by the fan increases
Solution Approach 1:
The fan dynamically adjusts its rotational speed based on real-time sensor data regarding occupancy and environmental conditions. The system operates at higher speeds when air circulation is needed and reduces speed when occupancy is low or air quality is already good, optimizing the balance between productivity and noise generation.
3Temperature
If ceiling fan is used to throw air downwards for cooling, then room temperature perception improves, but the fan requires significant ceiling height space
Solution Approach 1:
The fan system incorporates air purification and temperature modulation functions within the blade structure itself, adding vertical airflow dimension through integrated HEPA and UV filters. This allows the fan to provide cooling and air treatment in a compact form factor suitable for low-ceiling spaces.
4Adaptability or versatility
If multiple manual adjustments are needed to optimize fan performance for different conditions, then adaptability improves, but user time and effort increase
Solution Approach 1:
The fan system autonomously adapts to different environmental conditions and occupancy scenarios without requiring user intervention. Sensors detect room conditions and the compute unit automatically adjusts blade angles and rotational speed, eliminating the time and effort users would otherwise spend on manual adjustments.
Solution Approach 2:
Continuous sensor feedback regarding temperature, humidity, occupancy, and air quality enables the system to automatically adapt its performance characteristics. The compute unit processes this feedback in real-time and makes appropriate adjustments to maintain optimal conditions without user involvement.

AI summary
The present disclosure discloses a fan having a main hub and a main shaft. Each of the multiple fan blades has a detachable shaft to which a joinery assembly is detachably connected. The joinery assembly is configured to cause either angular shift or speed variation or both of the fan blades to impact air attack and air fluid dynamics of the fan on the basis of either of user input parameters or data collected from the multiple sensors or both. Thus, the fan dynamically changes either angular shift or speed variation or both of the fan blades to impact air attack and air fluid dynamics of the fan to provide the suction and circulation of cold or warm UV and HEPA purified air through the fan blades.
