Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air passage is shaped in annular or looped configuration for bladeless fan design, then safety is improved due to lack of external blades, but space efficiency deteriorates with large volume of unused space outlined by the air passage
Solution Approach 1:
The air passage is divided into multiple functional channels (inflow channel, outflow channel, and bypass channel) separated by internal walls. This segmentation allows each channel to serve a specific purpose while efficiently utilizing the overall air passage volume, eliminating unused space while maintaining the bladeless safe design.
Solution Approach 2:
The patent introduces internal three-dimensional structures including separation walls and bypass channels that utilize the vertical and radial dimensions within the air passage. This transforms the traditional two-dimensional annular passage into a multi-dimensional flow path system, maximizing space utilization without compromising safety.
2Reliability
If traditional bladeless fan design is used, then safety is improved, but cooling performance deteriorates due to lack of optimized pressure differentials and airflow efficiency
Solution Approach 1:
Different regions of the air passage are given different functional qualities: the inflow channel is designed for pressure buildup with heating elements, the outflow channel for high-velocity discharge with intake orifices, and the bypass channel for supplemental airflow. This local differentiation optimizes cooling performance while maintaining overall safety.
Solution Approach 2:
The patent applies pneumatic principles by creating pressure differentials through heated air in the inflow channel and utilizing the Venturi effect at the outflow channel. These pneumatic mechanisms enhance airflow efficiency and cooling performance without requiring external blades, thus maintaining safety.
3Productivity
If separation wall with heating element is added to create pressure differentials, then airflow efficiency is improved, but device complexity increases
Solution Approach 1:
The separation wall structure is merged with the heating element, integrating two functions (flow separation and air heating) into a single component. This reduces the number of separate parts and simplifies assembly while achieving the desired pressure differential and airflow efficiency.
Solution Approach 2:
The separation wall serves multiple functions simultaneously: it divides the air passage into distinct channels, provides mounting for heating elements, creates pressure differentials, and guides airflow patterns. This multi-functionality reduces overall device complexity by eliminating the need for separate components for each function.

AI summary
A bladeless cooling light includes an airflow assembly, a light assembly, and a housing. The airflow assembly includes an air circulation assembly positioned within the housing and an air passage structure connected to the housing, wherein the air circulation assembly draws air through the housing into the air passage structure. The air passage structure has a separation wall that delineates the air passage structure into an inflow air channel and an outflow air channel to improve the airflow through the air passage structure. A cone-tip hole grid and a wired heater within the air passage structure further improve airflow characteristics; the cone-tip hole grid constricts the flow, while the wired heater increases internal pressure by heating the air. The lighting assembly is mounted to the housing with the air passage structure being positioned around the lighting assembly, such that the light and expelled airflow are projected in the same direction.
