Ceiling Fan Projection Housing with Pattern Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling fans with projection functions suffer from interference of the projected image by the blades, motor, and hanging rod, resulting in incomplete and inconvenient projection.
Innovation Solution
A ceiling fan design incorporating a ceiling fan housing with a pattern hole unit and a light-emitting unit, where the light-emitting members project a beam through pattern holes arranged around the hanging rod, ensuring the pattern is displayed clearly on the ceiling without interference from the fan's components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the projection device is disposed under the ceiling fan, then it is convenient for users to operate, but the projected image is interfered with by the blades, motor and hanging rod resulting in incomplete projection
Solution Approach 1:
The patent changes the projection direction from upward (under the fan) to downward (through the housing). The light-emitting unit projects light beams downward through pattern holes in the ceiling fan housing, allowing the projection to occur below the fan without interference from rotating components. This dimensional reversal resolves the contradiction by maintaining user accessibility while eliminating projection interference.
2Ease of manufacture
If the projection device is arranged separately from the ceiling fan, then it is easy to install and maintain, but it occupies additional space and increases device complexity
Solution Approach 1:
The patent merges the projection device with the ceiling fan housing structure. The light-emitting unit is integrated into the ceiling fan housing, and the pattern holes are formed directly in the housing. This combination eliminates the need for separate projection device installation while maintaining ease of manufacture, as the integrated design reduces assembly steps and structural complexity.
Applied Scientific Principles
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 allows for a clear and complete projection of patterns onto the ceiling, enhancing user experience by eliminating interference from the fan's structural elements and providing effective heat dissipation through strategically placed heat dissipation holes.
Implementation Method 1
The light-emitting member of the light-emitting unit projects a light beam passing through the pattern hole of the pattern hole unit to project a pattern of the pattern hole of the pattern hole unit outside the ceiling fan housing

AI summary
A ceiling fan with a ceiling projection function includes a ceiling fan body and a ceiling fan housing. The ceiling fan body includes a plurality of blades, a motor that drives the blades to rotate, and a hanging rod. The ceiling fan housing is provided with a pattern hole unit and a light-emitting unit. The pattern hole unit has at least one pattern hole. The pattern hole of the pattern hole unit passes through the ceiling fan housing. The light-emitting unit has at least one light-emitting member. When in use, the light-emitting member of the light-emitting unit projects a light beam passing through the pattern hole of the pattern hole unit to project a pattern of the pattern hole of the pattern hole unit outside the ceiling fan housing and above the blades.
