Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If low-power transmission is used to maximize battery life and avoid FCC licensing, then energy consumption is reduced and licensing requirements are avoided, but communication range becomes limited and more infrastructure is required
Solution Approach 1:
The transceiver dynamically switches between low-power mode and high-power mode based on communication requirements. The system can adaptively select transmission power levels, transitioning from low-power operation for routine communications to high-power operation when extended range is needed, thereby resolving the contradiction between energy conservation and communication range.
Solution Approach 2:
The invention changes the power transmission parameter from fixed low-power to variable power levels. By adjusting the transmission power parameter, the system can operate in low-power mode for battery conservation or switch to high-power mode to extend communication range, directly addressing the contradiction between power consumption and range.
2Device complexity
If single-channel communication is used to simplify the protocol, then device complexity is reduced, but communication reliability deteriorates due to susceptibility to electromagnetic interference and noise
Solution Approach 1:
The transceiver is designed with multi-functionality to operate in both low-power single-channel mode and high-power multi-channel mode. This universal capability allows the system to use simple single-channel communication when conditions permit, but switch to more robust multi-channel operation when interference is detected, thereby improving reliability without permanently increasing protocol complexity.
Solution Approach 2:
The communication protocol dynamically adapts between single-channel and multi-channel operation based on environmental conditions. When electromagnetic interference is detected, the system transitions from simple single-channel protocol to more complex multi-channel protocol, ensuring reliable communication while maintaining simplicity under favorable conditions.
3Duration of action of moving object
If low-power transmission mode is used to extend battery life, then operational duration is extended, but communication range is reduced requiring more infrastructure
Solution Approach 1:
The system dynamically adjusts transmission power based on range requirements. For routine communications over short distances, low-power mode extends battery life. When longer range communication is needed, the system switches to high-power mode to extend the communication horizon, thereby resolving the contradiction between battery life and communication range.
Solution Approach 2:
The transmission power parameter is changed from fixed low-power to variable power levels. The system can operate at low power levels to maximize battery duration or increase power levels when extended range is required, directly addressing the contradiction between operational duration and communication range.
4Device complexity
If fixed-frequency channels are used to simplify communication, then device complexity is reduced, but susceptibility to interference from other electromagnetic radiation increases
Solution Approach 1:
The transceiver incorporates multi-functionality to operate on both fixed-frequency channels and spread-spectrum channels. This universal capability allows the system to use simple fixed-frequency communication when the spectrum is clear, but switch to interference-resistant spread-spectrum mode when electromagnetic interference is detected, thereby reducing interference susceptibility without permanently increasing system complexity.
Solution Approach 2:
The communication system dynamically selects between fixed-frequency and spread-spectrum modes based on interference conditions. When the electromagnetic environment is favorable, simple fixed-frequency communication is used. When interference from other devices is detected, the system transitions to spread-spectrum communication which is inherently more resistant to interference, thus resolving the contradiction between complexity and interference susceptibility.
