Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of operational transmission antennas is increased to improve signal strength, then signal quality is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the number of operational transmission antennas based on real-time wireless quality state and installation direction. The processor controls the RF transmission interface to activate only the necessary number of antennas required to maintain acceptable signal strength, rather than keeping all antennas continuously operational. This dynamic adjustment resolves the contradiction by optimizing signal quality while minimizing power consumption.
Solution Approach 2:
The system changes the operational parameters of the transmission antennas based on detected installation direction and wireless quality state. By adjusting which antennas are active and how many are operational, the system optimizes the balance between signal strength and power consumption. The processor modifies antenna operation parameters in response to environmental conditions, resolving the trade-off between reliability and energy use.
2Reliability
If manual evaluation and adjustment of installation environment is performed by service center, then wireless setting condition can be improved, but user convenience deteriorates
Solution Approach 1:
The system enables self-service by automatically detecting the installation direction of the A/V transmitting device and generating appropriate guidance information without requiring service center intervention. The processor analyzes the wireless quality state and installation direction to provide autonomous optimization, eliminating the need for users to contact service centers for installation environment evaluation while maintaining improved wireless settings.
Solution Approach 2:
The system implements feedback by detecting the wireless quality state and installation direction, then generating and transmitting guidance information back to the user. This closed-loop approach allows the system to automatically evaluate and improve the installation environment based on real-time conditions, resolving the contradiction between achieving optimal wireless settings and maintaining user convenience by eliminating manual service center visits.
3Reliability
If comprehensive user log analysis and service center visit is conducted to evaluate installation environment, then wireless optimization can be achieved, but time consumption and cost increase
Solution Approach 1:
The system performs preliminary action by automatically detecting installation direction and generating optimization guidance at the time of initial setup, eliminating the need for subsequent service center visits and lengthy log analysis processes. The processor immediately analyzes the wireless quality state and provides guidance information, achieving wireless optimization during the initial installation phase without consuming additional time or resources.
Solution Approach 2:
The system replaces the mechanical process of service center visits and manual log analysis with an automated electronic detection and processing system. The processor electronically detects installation direction and wireless quality state, then generates optimization guidance automatically, substituting the time-consuming manual evaluation process with rapid electronic analysis that achieves the same optimization goal instantaneously.
