Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communications frequency is fixed, then device complexity is reduced, but adaptability deteriorates due to inability to change frequency in field
Solution Approach 1:
The patent replaces mechanical DIP switches with a wireless communication-based setting mechanism. The transceiver reads setting information wirelessly from a portable terminal, eliminating the need for physical switches and enabling frequency changes without mechanical intervention. This substitution resolves the contradiction by providing adaptability through wireless settings while keeping the device structure simple.
Solution Approach 2:
The transceiver automatically reads and applies setting information from the portable terminal without requiring manual switch operations. The system performs self-configuration by receiving wireless signals containing frequency settings and automatically adjusting its operation, thereby achieving adaptability without adding complex manual setting mechanisms.
2Adaptability or versatility
If many setting switches are provided, then adaptability is improved, but reliability deteriorates due to intrusion of foreign material
Solution Approach 1:
The patent eliminates mechanical DIP switches and replaces them with a wireless communication-based setting system. Setting information is transmitted wirelessly from a portable terminal to the transceiver, completely removing physical switches that could accumulate foreign materials like iron powder. This substitution maintains setting flexibility while dramatically improving reliability by eliminating the mechanical interface vulnerable to contamination.
3Device complexity
If PC is used to set wireless communications frequency, then device complexity is reduced, but productivity deteriorates due to need to connect each tool individually
Solution Approach 1:
The patent creates a universal setting mechanism where a single portable terminal can wirelessly configure multiple transceivers. The portable terminal serves as a multi-functional device that can communicate with and set various tools without physical connections. This universal approach maintains simplicity while dramatically improving productivity by enabling batch settings of multiple devices through wireless communication.
Solution Approach 2:
The patent replaces the mechanical connection required for PC-based settings with wireless communication. The portable terminal transmits setting information wirelessly to the transceiver, eliminating the need for physical cable connections. This substitution maintains the simplicity of external setting while dramatically improving productivity by allowing rapid wireless configuration of multiple tools without repeated physical connections.
4Ease of operation
If wireless communications are used, then ease of operation is improved, but reliability deteriorates due to communications errors from environmental noise
Solution Approach 1:
The patent implements dynamic frequency selection where the transceiver can change its operating frequency based on wireless communication conditions. By dynamically adjusting the frequency band, the system avoids stationary frequencies that may be subject to persistent interference, thereby maintaining communication accuracy while preserving the convenience of wireless operation.
Solution Approach 2:
The patent changes communication parameters including frequency and other settings based on environmental conditions and interference levels. By adjusting these parameters dynamically, the system maintains reliable communication in noisy factory environments while preserving the ease of wireless operation. The portable terminal and transceiver negotiate optimal parameters to ensure accurate settings transmission.
