Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the diameter of the antenna system is increased to improve gain and beam coverage, then the antenna performance is improved, but the wind load increases and stability deteriorates
Solution Approach 1:
The patent converts the harmful wind load into a beneficial force by enabling the blade to rotate under wind action, generating centrifugal force that actively reduces the wind load on the antenna system. The reflection plate with through-holes allows wind to pass through and drive the blade rotation, transforming the adverse wind effect into a useful mechanism for load reduction.
Solution Approach 2:
The patent introduces dynamic elements (the rotatable blade and through-holes in the reflection plate) that allow the antenna system to adapt to wind conditions. The blade rotates dynamically under wind force, changing the airflow pattern and reducing static wind load on the antenna structure.
2Productivity
If the diameter of the antenna system is increased to improve network system capacity, then the coverage is improved, but the pole support capability is exceeded and reliability decreases
Solution Approach 1:
The patent transforms the wind load that would otherwise overload the pole support into a useful rotational force. The blade captures wind energy to rotate, generating centrifugal effect that reduces the net wind load on the pole, enabling larger antenna diameters without exceeding pole support capabilities.
Solution Approach 2:
The patent changes the physical parameters of the system by introducing moving parts (blade rotation) that dynamically alter the wind load characteristics. The rotation speed and centrifugal force vary with wind conditions, creating a adaptive load reduction mechanism that maintains pole support reliability.
3Area of moving object
If the diameter of the antenna system is increased to improve gain, then the beam coverage is improved, but the wind load becomes excessively large and causes damage
Solution Approach 1:
The patent converts the harmful excessive wind load into a beneficial rotational motion. The blade, positioned to capture wind flow through the reflection plate holes, rotates under wind force and generates centrifugal effect that actively counteracts the wind load, protecting the antenna from damage while enabling larger diameter construction.
Solution Approach 2:
The rotating blade generates centrifugal force that acts as a dynamic counterweight effect, opposing the wind load on the antenna system. This centrifugal force reduces the net load on the structure, allowing larger antenna diameters without proportionally increasing the damaging wind load effect.
