Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling fans lack continuous color temperature control, requiring users to manually replace light kits or use mechanical switches to adjust light warmth, which is inconvenient and limited in flexibility.
Innovation Solution
A ceiling fan with an integrated electric lamp using a bi-phasic dimming mechanism and triac dimming unit, allowing for continuous adjustment of color temperature between 1,250 K and 9,900 K without light blinking or flickering, using two sets of LEDs with half-wave rectifiers and a modified triac dimmer to control the AC waveform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional ceiling fans use fixed light kits or mechanical switches for light warmth adjustment, then the device complexity is reduced, but the adaptability and ease of operation deteriorate
Solution Approach 1:
The patent implements continuous color temperature adjustment capability, transforming the static lighting system into a dynamic one where users can seamlessly adjust light warmth across a spectrum from warm (1,250K) to cool (9,900K) without discrete steps or manual interventions
Solution Approach 2:
The integrated lighting system combines multiple functions into a single ceiling fan unit, including both fan operation and adjustable lighting control, eliminating the need for separate light fixtures and providing unified control through the remote control device
2Ease of operation
If manual replacement of light kits is required to adjust light warmth, then the device complexity is reduced, but the loss of time and ease of operation worsen
Solution Approach 1:
The system pre-configures a full spectrum of color temperature options within the integrated lighting system, allowing users to access any desired warmth level instantly without requiring preliminary actions such as climbing ladders or replacing physical light kits
Solution Approach 2:
The patent replaces the mechanical approach of physically replacing light kits with electronic control mechanisms, using a remote control device to adjust color temperature through wireless communication, thereby eliminating manual intervention and time consumption
3Measurement precision
If discrete light warmth settings are used with mechanical switches, then the device complexity is reduced, but the adaptability and measurement precision deteriorate
Solution Approach 1:
The system provides continuous, stepless adjustment of color temperature across the entire spectrum from 1,250K to 9,900K, transforming discrete mechanical switch positions into a dynamic continuum where users can select any precise warmth level without being constrained to predetermined settings
Solution Approach 2:
The patent implements fine-grained control over the color temperature parameter, allowing users to adjust and precisely set the light warmth to any value within the specified range, thereby achieving high measurement precision in color temperature control
4Adaptability or versatility
If integrated electric lamp with continuous color temperature control is added to ceiling fan, then the adaptability and ease of operation improve, but the device complexity increases
Solution Approach 1:
The patent merges the lighting system and fan system into a single integrated ceiling fan unit, combining the electric motor, blades, and electric lamp with continuous color temperature control into one unified device that is co-located and controlled together
Solution Approach 2:
The integrated ceiling fan provides multiple functions including air circulation through the motor and blades, and adjustable lighting through the electric lamp with continuous color temperature control, eliminating the need for separate light fixtures and providing unified control

AI summary
Ceiling fan having an electric lamp which has continuous color temperature control. A ceiling fan includes an electric motor which rotates blades; and an electric lamp, which is an integrated component of the ceiling fan and is co-located beneath the blades. The motor and the lamp receive electric power from a mains electric socket via a single electric power cord that provides Alternating Current. The lamp is configured to emit visible light having light warmth at a user-configurable level along a continuous spectrum of light warmth, between a lower-bound value and an upper-bound value. The electric lamp includes a first set of LEDs and a second set of LEDs. The first set of LEDs is capable of emitting visible light at a first, fixed, light warmth value, which is the lower-bound value of that continuous spectrum of light warmth levels. The second set of LEDs is capable of emitting visible light at a second, fixed, light warmth value, which is the upper-bound value of that continuous spectrum of light warmth levels.
