Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connection is used for setting transfer, then connection stability is improved, but work efficiency and ease of operation deteriorate due to cable insertion complexity and exposure to harsh environments
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The setting transfer device establishes wireless communication with the wireless device to transfer setting information, eliminating the need for physical cable connections while maintaining reliable data transmission.
Solution Approach 2:
The setting transfer device acts as an intermediary between the operator and the wireless device. It receives setting information from the operator and transfers it wirelessly to the target wireless device, simplifying the operation process without requiring direct wired connection at the installation location.
2Use of energy by moving object
If hardware switch is used for power management, then power consumption control is improved, but ease of operation deteriorates in harsh environments requiring protection against water, dust, and explosion
Solution Approach 1:
The patent replaces the mechanical hardware switch with wireless communication for power management. The setting transfer device wirelessly transmits wake-up signals to activate the wireless device from sleep mode, and can also wirelessly receive power transmission to operate the device without physical contact, eliminating the need for exposed mechanical switches.
Solution Approach 2:
The setting transfer device serves as an intermediary for power management operations. It transmits wake-up signals wirelessly to activate the wireless device and can receive power wirelessly through NFC, providing a protected interface that doesn't require physical exposure to harsh environments.
3Ease of operation
If wireless communication is used for setting transfer, then work efficiency and ease of operation are improved, but connection stability and reliability may deteriorate in harsh industrial environments
Solution Approach 1:
The setting transfer device acts as a reliable intermediary that manages the wireless communication process. It establishes stable wireless connections, transfers setting information reliably, and can also provide wired connection capabilities as a backup or alternative method to ensure connection stability in harsh industrial environments.
Solution Approach 2:
The setting transfer device provides multiple communication modes including wireless communication for efficient setting transfer and wired connection capabilities for enhanced reliability. This multi-functional approach ensures both work efficiency and connection stability can be achieved depending on environmental conditions.
