Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If additional wires are connected to light sources to transmit electricity, then light sources can be powered, but flow resistance increases and heat dissipation efficiency decreases
Solution Approach 1:
The patent merges the light source mounting function with the heat sink structure itself. The light sources are directly mounted on the heat sink's surface, eliminating the need for separate wire connections through the airflow path. This integration allows electrical power to reach light sources without introducing additional flow resistance elements.
Solution Approach 2:
The patent extracts the wires from the airflow path by mounting light sources directly on the heat sink. This removal of wires from the critical airflow region eliminates the flow resistance and turbulence that wires would create, while still maintaining electrical connectivity to the light sources.
2Illumination intensity
If light sources are projected from the inner wall of the fan to face the heat sink, then lighting efficiency is improved, but flow resistance increases and flow field changes
Solution Approach 1:
Instead of projecting light from the fan's inner wall toward the heat sink, the patent inverts the approach by mounting light sources directly on the heat sink's surface. This reversal positions the light sources at the optimal location for both illumination and minimal airflow interference, eliminating the need for long light paths through the fan structure.
Solution Approach 2:
The patent applies local quality by positioning light sources specifically on the heat sink surface where they are most needed for illumination, rather than distributing them throughout the fan structure. This localized placement optimizes both lighting efficiency and heat dissipation by concentrating light emission at the target area without disrupting overall airflow.
3Illumination intensity
If light sources are disposed in the fan, then light can be emitted, but flow resistance increases due to obstruction of airflow path
Solution Approach 1:
The patent extracts light sources from the fan's airflow path and relocates them to the heat sink's surface. This extraction removes the obstruction caused by light sources within the fan, eliminating flow resistance and turbulence while maintaining light emission functionality for illumination purposes.
