Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the outer shell is designed as a solid wall body with light-emitting components installed inside, then the structural integrity and simplicity are improved, but the heat dissipation efficiency deteriorates because heat is retained inside the shell
Solution Approach 1:
The outer shell is segmented into multiple regions by forming several rib plates that extend from the top to the bottom of the shell. This segmentation creates multiple heat dissipation channels while maintaining the overall structural integrity of the shell. The rib plates divide the internal space into separate compartments, allowing heat to be channeled through defined paths to the external environment.
Solution Approach 2:
The heat dissipation structure transitions from a two-dimensional surface (traditional heat sinks) to a three-dimensional spatial arrangement by forming vertical rib plates that extend throughout the height of the shell. This creates volumetric heat dissipation channels that utilize the vertical dimension, significantly increasing the heat dissipation surface area and efficiency without compromising structural strength.
2Temperature
If aluminum fins are added to the light-emitting component for heat dissipation, then the local heat dissipation capability is improved, but the overall heat dissipation effectiveness deteriorates because heat remains trapped inside the shell
Solution Approach 1:
The heat dissipation function is extracted from the light-emitting component itself and transferred to the shell structure. Instead of relying solely on fins attached to the LED, the shell's rib plates serve as the primary heat dissipation pathway, conducting heat from the light-emitting components through the rib plates to the external environment. This separates the light emission function from the heat dissipation function.
Solution Approach 2:
The rib plates act as intermediary heat conduction elements between the light-emitting components and the external environment. These rib plates provide dedicated thermal pathways that mediate the heat transfer process, efficiently conducting heat away from the light-emitting components through the shell structure without requiring direct attachment of traditional heat sinks to the LEDs.
3Ease of manufacture
If the shell is designed as a solid wall body, then the manufacturing simplicity is improved, but the heat dissipation performance deteriorates due to lack of heat dissipation structures
Solution Approach 1:
The shell is segmented into multiple regions by forming several rib plates that extend from the top to the bottom of the shell. This segmentation creates multiple heat dissipation channels while maintaining the overall structural integrity of the shell. The rib plates divide the internal space into separate compartments, allowing heat to be channeled through defined paths to the external environment.
Solution Approach 2:
The shell structure undergoes parameter changes by introducing rib plates with specific geometric parameters (height, thickness, spacing) that optimize heat dissipation. The rib plates are configured with dimensions and arrangements that maximize thermal conductivity and surface area for heat dissipation, transforming the shell from a simple enclosure to an active heat dissipation system while maintaining manufacturability.
