Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an investigator physically visits the site to investigate radio wave interference, then the investigation can be performed, but time and effort are consumed
Solution Approach 1:
The wireless communication device autonomously performs radio wave interference investigation by itself without requiring external investigator intervention. The device uses its own radio wave reception unit to collect interference data, the control unit to analyze the data and determine interference sources, and the display unit to present results, thereby eliminating the need for physical site visits by investigators.
Solution Approach 2:
The patent replaces the mechanical process of physical site investigation with an automated electronic system. The control unit substitutes for the human investigator's analytical work by automatically processing radio wave data, calculating interference sources based on signal strength and direction, and generating investigation results without requiring physical presence at the location.
2Reliability
If radio wave interference is occurring, then service quality decreases, but it is difficult to determine what action to take to avoid interference influence
Solution Approach 1:
The system provides feedback to the user by displaying the determined radio wave interference source information on the display unit. This feedback includes the location and characteristics of the interference source, enabling users to understand what is causing the service quality degradation and what actions can be taken to mitigate it, such as changing position or adjusting antenna orientation.
Solution Approach 2:
The control unit acts as an intermediary between the complex radio wave interference phenomenon and the user. It processes the raw radio wave data, identifies the interference source, and presents the information in a user-friendly format, making the invisible interference visible and actionable without requiring the user to have technical expertise in radio wave analysis.
3Productivity
If general throughput decrease detection is used, then interference investigation can be triggered, but the specific cause cannot be identified without site investigation
Solution Approach 1:
The system performs preliminary action by continuously monitoring radio wave conditions and automatically investigating interference sources as soon as throughput decrease is detected, rather than waiting for site investigation. The control unit immediately analyzes the radio wave data to identify the interference source, preserving information about what caused the throughput decrease before any physical investigation occurs.
Solution Approach 2:
The wireless communication device performs self-diagnosis by using its own reception unit and control unit to identify the interference source that is causing throughput degradation. This self-service capability eliminates the information loss that would occur if the device had to wait for external investigators to arrive and perform analysis.
