Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional heatsinks and fans are used for cooling antenna arrays, then cooling effectiveness is improved, but device size and weight increase significantly
Solution Approach 1:
The patent divides the antenna array into multiple antenna elements and assigns individual thermoelectric cooling devices to specific subsets of antenna elements. This segmentation allows the cooling system to be distributed and miniaturized rather than requiring a single large heatsink and fan assembly, thereby reducing overall device weight while maintaining effective cooling.
Solution Approach 2:
The patent replaces the mechanical cooling system (fans and heatsinks) with solid-state thermoelectric cooling devices. This substitution eliminates the need for moving parts, large heat dissipation structures, and associated mounting hardware, significantly reducing the weight of the cooling system while maintaining effective temperature control.
2Temperature
If conventional heatsinks and fans are used for cooling antenna arrays, then cooling effectiveness is improved, but device complexity and maintenance requirements increase
Solution Approach 1:
The patent replaces mechanical cooling components (fans, motors, large heatsinks) with solid-state thermoelectric devices that have no moving parts. This eliminates mechanical failures, reduces maintenance requirements, and simplifies the overall cooling system architecture while maintaining effective temperature control of antenna elements.
Solution Approach 2:
The patent employs thermoelectric devices that convert electrical parameters directly into thermal gradients through the Peltier effect. By changing the electrical current parameters supplied to each thermoelectric device, the system can dynamically adjust cooling levels for different antenna elements without requiring complex mechanical adjustments or multiple cooling components.
3Use of energy by moving object
If adaptive cooling is applied to different subsets of antenna elements, then power consumption efficiency is improved, but control system complexity increases
Solution Approach 1:
The patent applies different cooling levels to different subsets of antenna elements based on their specific operational requirements. Each thermoelectric cooling device can be independently controlled to provide localized cooling where needed, rather than uniformly cooling the entire antenna array. This local quality approach optimizes power consumption by avoiding unnecessary cooling of antenna elements that are not generating excessive heat.
Solution Approach 2:
The patent implements dynamic control of thermoelectric cooling devices based on real-time operational conditions of antenna elements. The control system adjusts cooling levels dynamically according to traffic load, environmental conditions, and thermal states of different antenna subsets, enabling energy-efficient operation while adapting to changing conditions without requiring overly complex predetermined control logic.
