Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a large number of heat dissipation fins are used to improve heat dissipation performance, then heat dissipation performance is improved, but manufacturing cost greatly increases
Solution Approach 1:
The patent applies multi-functionality by designing fins that serve dual purposes: structure supporting fins provide both structural support and heat dissipation, while assistant fins provide both structural support and heat dissipation. This eliminates the need for numerous dedicated heat dissipation fins, reducing manufacturing cost while maintaining effective heat dissipation performance.
2Length of moving object
If the length of the plant growth lighting device is increased, then the lighting coverage is improved, but structural strength becomes insufficient
Solution Approach 1:
The patent applies segmentation by dividing the long device into multiple sections with structure supporting fins positioned at intervals along the length. These fins act as structural reinforcements that segment the long body, providing structural strength to support greater device lengths while enabling extended lighting coverage.
Solution Approach 2:
The patent adds structural support in the vertical dimension by incorporating structure supporting fins that extend perpendicular to the main device body. This dimensional addition provides structural reinforcement without increasing the device length, enabling longer devices to maintain adequate structural strength.
3Area of stationary object
If the number of heat dissipation fins is increased to improve heat dissipation, then heat dissipation area is increased, but device complexity increases
Solution Approach 1:
The patent reduces device complexity by making fins multi-functional. Structure supporting fins and assistant fins both contribute to heat dissipation while providing structural support, eliminating the need for separate dedicated heat dissipation fins and simplifying the overall device structure.
Solution Approach 2:
The patent merges the functions of structural support and heat dissipation into single components. The structure supporting fins and assistant fins combine both functions, reducing the total number of components needed and simplifying device complexity while maintaining adequate heat dissipation area.
