Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional incandescent or fluorescent lamps are used in ceiling fans, then the lighting function is provided, but the color-changing capability and adaptability to different times of day are absent
Solution Approach 1:
The patent combines multiple LED types (white LEDs and RGB LEDs) into a single integrated lamp assembly, merging the functions of general illumination and color-changing capabilities into one unified structure. This allows the ceiling fan to provide both standard lighting and adaptive color changes based on time of day, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The lamp assembly is designed to perform multiple functions: providing general illumination through white LEDs and enabling color-changing effects through RGB LEDs. The single integrated structure serves both purposes simultaneously, making the device universal and adaptable to different lighting needs throughout the day without requiring separate lighting systems.
2Adaptability or versatility
If planar LED lamps are used, then the lighting function is provided, but the varied geometrical shapes, sizes and orientations are absent
Solution Approach 1:
The lamp assembly is divided into distinct functional segments: white LED modules for general illumination and RGB LED modules for color effects. These segmented components can be independently configured and arranged in various geometrical patterns, allowing for diverse shapes and orientations while maintaining a manageable overall structure that doesn't excessively increase device complexity.
Solution Approach 2:
The patent incorporates LEDs arranged in three-dimensional space rather than just a planar configuration. By adding vertical and radial dimensions to the LED arrangement, the lamp can achieve varied geometrical shapes and orientations that adapt to different ceiling fan designs and lighting requirements, resolving the limitation of planar-only configurations.
3Use of energy by moving object
If LEDs are integrated into the ceiling fan, then energy efficiency is improved, but heat generation requires cooling mechanisms
Solution Approach 1:
The patent introduces heat sinking elements as intermediary components between the LED light sources and the surrounding environment. These heat sinks act as thermal mediators that capture and dissipate heat generated by the energy-efficient LEDs, allowing the system to maintain high energy efficiency while effectively managing temperature through dedicated thermal management structures.
