Ceiling Fan and Heater Assembly with Integrated Lighting Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceiling fans are ineffective in heating enclosed spaces, especially in cold weather, as they primarily circulate air without adding heat, leading to discomfort and inefficient energy use, and existing solutions that combine fans with heaters lack integrated lighting effects.
Innovation Solution
A combination assembly of a ceiling fan and heater with a rotating translucent band and motor-driven reflective foils equipped with LEDs, which creates a heating system that distributes heated air through the fan blades, while the LEDs shine through the translucent band to produce a flickering light effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a ceiling fan is used to circulate air in cold weather, then air circulation is improved, but heating effectiveness deteriorates because the fan does not add heat to the air
Solution Approach 1:
The patent combines a ceiling fan assembly with a heater assembly into a single integrated unit. The fan motor and heater are housed together in the same housing structure, allowing the device to both circulate air and heat it simultaneously. This merging resolves the contradiction by enabling both air circulation and heating functions in one device.
Solution Approach 2:
The integrated ceiling fan and heater unit performs multiple functions: it can operate as a standalone ceiling fan for air circulation, as a heater for warming rooms, and in combination mode where the heater heats air that the fan then distributes throughout the space. This multi-functionality addresses the limitation of ceiling fans being ineffective for heating.
2Temperature
If a heater is added to a ceiling fan assembly, then heating capability is improved, but device complexity increases
Solution Approach 1:
The patent integrates the heater assembly within the existing ceiling fan housing structure. The heater is positioned in the lower housing portion, and the fan blades are arranged to draw heated air from the heater and distribute it throughout the room. This merging of components into a single housing reduces the complexity that would arise from having separate fan and heater units.
Solution Approach 2:
The heater assembly is nested within the ceiling fan housing structure. The skirt portion of the housing encloses the heater, and the fan blades extend over the heater area. This nesting arrangement allows the heater to be contained within the fan assembly, utilizing the existing structural space rather than requiring a completely separate housing.
3Loss of energy
If air is blown through a heater, then heating efficiency is improved, but the draft effect worsens comfort in cold rooms
Solution Approach 1:
The patent positions the heater at the bottom of the fan assembly, directly in the path of the downward airflow created by the fan blades. This local positioning ensures that the fan air is heated as it passes over the heater elements, maximizing heating efficiency. The skirt enclosure directs the heated air outward toward the room, creating effective heat distribution without excessive localized drafts.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively heats and circulates air in a room, enhancing occupant comfort and reducing energy costs by integrating a heater with the ceiling fan, while also providing a visually appealing lighting effect.
Implementation Method 1
a heating fan driven by a heating fan motor mounted within the lower housing to pass air over the heater
Implementation Method 2
lighting elements mounted with the reflective foils to shine light through the translucent band
Implementation Method 3
a plurality of reflective foils mounted for rotation in the main housing in the lower housing portion in the horizontal plane
