Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If infrared LEDs are assembled in the housing, then the camera can capture clear images at night or in low illuminance, but the heat generated by high power infrared LEDs can cause thermal damage
Solution Approach 1:
The patent introduces a heat dissipation bracket as an intermediary component between the infrared LEDs and the housing. This bracket serves as a thermal mediator that conducts heat away from the LEDs through dedicated heat dissipation pathways, preventing direct thermal damage to surrounding components while maintaining effective infrared illumination.
Solution Approach 2:
The patent extracts the heat dissipation function from the main housing structure by implementing a separate, dedicated heat dissipation bracket. This separation allows the housing to focus on structural and optical functions while the specialized bracket handles thermal management, reducing overall thermal risk to the camera system.
2Reliability
If a complex assembly structure is used to support LED substrates and dissipate heat, then thermal damage is prevented, but the assembly process becomes complicated
Solution Approach 1:
The patent merges multiple functions into the heat dissipation bracket: mechanical support for LED substrates, heat conduction pathways, and structural attachment to the housing. This consolidation reduces the number of separate components and assembly steps while maintaining effective thermal management and structural integrity.
Solution Approach 2:
The heat dissipation bracket serves multiple purposes simultaneously: it provides mechanical support for the LED substrates, conducts heat away from the high power infrared LEDs, and attaches the entire LED assembly to the housing. This multi-functionality simplifies the overall assembly process while ensuring reliable thermal damage prevention.
