Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an individual light source is located separately from the fan, then the lighting function can be provided, but the operation convenience deteriorates and the lighting angle area becomes fixed
Solution Approach 1:
The patent combines the lighting device with the fan body into a single integrated unit. The light source is mounted on the fan body, allowing the fan to perform both ventilation and lighting functions simultaneously. This merging eliminates the need for separate lighting fixtures and enables the lighting to be controlled through the same operational mechanisms as the fan.
Solution Approach 2:
The patent incorporates an adjusting device that allows the lighting direction to be dynamically changed. The light source can be positioned at different angles and orientations on the fan body, enabling users to adjust the lighting direction according to their needs. This dynamic adjustability transforms the fixed lighting angle problem into a flexible solution.
2Ease of operation
If the lighting device is integrated on the fan body, then the operation convenience improves, but the device complexity increases
Solution Approach 1:
The patent creates a multi-functional device where the fan body serves both ventilation and lighting purposes. By integrating the lighting device into the fan body, the same structural platform is used for dual functions, reducing the need for separate components. This universality approach, while adding some complexity, ultimately simplifies the overall system by eliminating the need for independent lighting installations.
3Adaptability or versatility
If the illuminating device is made adjustable with horizontal rotation and vertical luffing, then the lighting direction flexibility improves, but the device complexity increases
Solution Approach 1:
The patent implements a dynamic adjusting mechanism with horizontal rotation and vertical luffing capabilities. The light source can rotate horizontally and tilt vertically, providing flexible lighting direction control. This dynamic design allows the lighting to adapt to different operational requirements while maintaining a relatively simple mechanical structure based on connecting shafts and angle irons.
4Ease of manufacture
If the fan and lighting are separate devices, then the manufacturing simplicity is maintained, but the space occupation increases during storage and transport
Solution Approach 1:
The patent merges the fan and lighting devices into a single integrated unit. The lighting device is mounted on the fan body, allowing both components to occupy the same spatial envelope during storage and transport. This consolidation reduces the total volume required for storage while maintaining the manufacturing simplicity of producing a unified device rather than coordinating separate components.

AI summary
The present disclosure relates to the field of ventilation technique. A multifunction lighting electric fan includes a fan body for blowing, a base plate for supporting the fan body and an illuminating device connecting to the fan body. The illuminating device in the present disclosure can be turned freely to change the irradiation direction of the light. The lighting electric fan can both ventilate and light, which satisfy the using needs in the evening. Because the irradiation direction of the lamplight can be adjusted, the lighting electric fan can be used widely and achieve high applicability.
