Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple parts and LED light sources are added to achieve illumination in different directions, then illumination coverage is improved, but assembly complexity and maintenance difficulty increase
Solution Approach 1:
The light guide is divided into multiple segments (first light guide portion, second light guide portion, third light guide portion) that can be independently assembled and maintained. Each segment can be separately installed on the fan blades without requiring complete disassembly of the entire lighting system, thus reducing assembly complexity while maintaining comprehensive illumination coverage.
Solution Approach 2:
The light guide segments are designed with universal mounting features that can be attached to different fan blade configurations. The same basic light guide segment design can illuminate multiple directions (front, rear, side) depending on its position, eliminating the need for completely different components for each illumination direction.
2Adaptability or versatility
If multiple parts and LED light sources are added to achieve illumination in different directions, then illumination coverage is improved, but maintenance and parts replacement efficiency deteriorate
Solution Approach 1:
By segmenting the light guide into separate replaceable portions, maintenance personnel can replace only the defective segment rather than the entire lighting system. This modular approach significantly reduces maintenance time and improves repair efficiency while still providing comprehensive multi-directional illumination when all segments are installed.
Solution Approach 2:
The light guide segments are designed to be extractable from the fan assembly without removing the entire fan or other components. Each segment can be independently accessed and replaced, allowing for quick maintenance operations that minimize downtime while maintaining full illumination functionality.
3Adaptability or versatility
If multiple parts and LED light sources are added to achieve illumination in different directions, then illumination coverage is improved, but assembly time increases
Solution Approach 1:
The segmented light guide design allows for staged assembly where portions can be installed independently or in parallel by multiple workers. This reduces the critical path of assembly and enables faster overall installation compared to installing a single large integrated lighting system, while achieving the same total illumination coverage.
Solution Approach 2:
The light guide segments can be pre-assembled or pre-positioned on separate components before final assembly. For example, light guide portions can be pre-attached to individual blades or pre-bunched together, reducing the complexity and time of the final assembly operation while maintaining comprehensive illumination coverage.
