Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipation fins are provided on the back surface side of the reflector plate, then heat dissipation performance is improved, but when mounted on a wall surface or pillar, the majority of the heat dissipation fins are covered and heat dissipation performance becomes limited
Solution Approach 1:
The heat dissipation fins are changed from a planar arrangement on the back surface to a three-dimensional arrangement standing on the reflective surface. This dimensional change allows the fins to extend outward in space, ensuring that even when the device is mounted on a wall or pillar, the fins remain exposed to airflow from multiple directions, thereby maintaining effective heat dissipation performance while preserving mounting flexibility.
2Temperature
If a metal reflector plate occupying a relatively large area is utilized as a heat dissipation path, then heat dissipation performance per volume is improved, but the device size increases
Solution Approach 1:
Instead of expanding the reflector plate area in two dimensions to improve heat dissipation, the invention utilizes the third dimension by standing heat dissipation fins on the reflective surface. This vertical arrangement increases the heat dissipation surface area without significantly increasing the device's footprint or volume, thereby improving heat dissipation performance per volume while maintaining a compact device size.
Solution Approach 2:
The invention concentrates heat dissipation functionality at specific locations where fins are stood on the reflective surface, rather than requiring a uniformly large reflector plate. This localized approach to heat dissipation allows effective thermal management with a smaller overall device volume.
