Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations or appliances are replaced to ensure correct voltage supply, then voltage compatibility is improved, but cost and time consumption increase significantly
Solution Approach 1:
The patent introduces a voltage adaption unit as an intermediary device installed between the base station and the TMA. This unit contains voltage regulating means that can adjust the voltage level to match the TMA's requirements, eliminating the need to replace either the base station or the TMA. The unit acts as a mediator that resolves the voltage incompatibility issue in place.
Solution Approach 2:
The voltage adaption unit changes the voltage parameter of the power supply by incorporating voltage regulating means capable of adjusting voltage to different levels (e.g., 12V, 24V, 48V). This allows the system to adapt to different TMA voltage requirements without physical replacement of equipment.
2Reliability
If base stations or appliances are replaced to ensure correct voltage supply, then voltage compatibility is improved, but expense increases significantly
Solution Approach 1:
The voltage adaption unit serves as a cost-effective intermediary solution rather than replacing expensive base stations or TMAs. The unit contains voltage regulating means and can be installed as an add-on device, significantly reducing implementation costs compared to full equipment replacement.
Solution Approach 2:
The voltage adaption unit is designed to be universal and compatible with multiple TMA models and voltage requirements. It can regulate voltage to different levels (12V, 24V, 48V) and works with various appliance types (amplifiers, antennas, motors), providing multi-functional capability that reduces the need for multiple specialized devices.
3Device complexity
If DC voltage regulation is implemented in a single pathway, then voltage control is simplified, but signal transmission and power transmission interfere with each other
Solution Approach 1:
The patent divides the transmission pathway into two separate pathways: a first pathway for transmitting RF signals and AC voltage, and a second pathway for transmitting DC voltage. This segmentation prevents interference between RF signals and DC voltage regulation, allowing each pathway to be optimized for its specific function without compromising signal integrity.
Solution Approach 2:
The patent introduces blocking means as intermediary elements at the boundaries between pathways. DC voltage blocking means prevent DC from entering the RF pathway, while RF blocking means prevent RF signals from entering the DC pathway. These intermediaries ensure clean separation and prevent interference between the two pathways.
