Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a relay device is installed using dedicated measurement devices or specialized knowledge, then the reception situation can be properly checked and a proper location can be selected, but the ease of installation deteriorates because specialized knowledge and equipment are required
Solution Approach 1:
The relay device performs self-measurement of reception situations by automatically transmitting test signals and measuring signal strength without requiring external measurement devices. The device uses its own transmitters and receivers to assess communication quality and determine optimal installation locations autonomously
Solution Approach 2:
The relay device integrates multiple functions including data relay, self-testing, reception measurement, and location determination into a single device. By combining the relay function with measurement and testing capabilities, the device eliminates the need for separate specialized equipment
2Length of stationary object
If only long-distance communication scheme is used, then the communication distance is extended, but the ease of determining installation location deteriorates because short-distance communication for testing is not available
Solution Approach 1:
The communication system is segmented into two distinct communication schemes: a long-distance scheme for actual data relay operations and a short-distance scheme for installation testing and location determination. This segmentation allows each scheme to be optimized for its specific purpose without compromising the other
3Ease of operation
If multiple communication schemes are used simultaneously, then the ease of installation is improved by enabling self-testing, but the device complexity increases
Solution Approach 1:
The relay device dynamically switches between different communication schemes based on the operational context. During installation, the short-distance scheme is activated for testing, while the long-distance scheme is used during normal operation. This dynamic adaptation allows a single device to handle multiple scenarios without requiring permanent configuration of all modes
