Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high DC power is delivered through long cables to radio equipment at the top of tall cell towers, then the radio equipment can operate with sufficient power, but voltage drop and power loss in the cable increase proportionally to current and square of current respectively
Solution Approach 1:
The patent changes the voltage parameter by introducing a voltage boost circuit that selectively increases the DC voltage level when battery power is detected. By boosting the voltage before transmission through the cable, the system reduces the current required to deliver the same power, thereby reducing I²R losses in the cable while maintaining adequate power delivery to the radio equipment
2Power
If high current is drawn through the cable to meet radio equipment power demands, then sufficient power reaches the equipment, but the voltage drop becomes significant and may fall below minimum operating voltage
Solution Approach 1:
The system dynamically adjusts the voltage parameter by detecting when battery power is being used and activating a voltage boost circuit. This increases the output voltage from the power source, compensating for the voltage drop across the long cable and ensuring the radio equipment receives sufficient voltage to maintain reliable operation
Solution Approach 2:
The patent implements feedback by using processing circuitry to detect the power source type (battery or non-battery) and control the voltage boost circuit accordingly. The system monitors the power source condition and adjusts the voltage output to maintain reliability, creating a closed-loop control system that responds to changing conditions
3Duration of action of moving object
If battery voltage diminishes as charge is depleted, then the battery provides backup power, but the voltage at the radio equipment input falls below the minimum required level
Solution Approach 1:
The patent applies parameter change by boosting the voltage parameter when battery power is detected. The voltage boost circuit compensates for the natural voltage decline of the battery as it discharges, maintaining the voltage at the radio equipment input above the minimum required level and thereby extending the effective duration of battery operation
Solution Approach 2:
The system takes preliminary anti-action by proactively boosting the voltage before the battery voltage drops too low. The processing circuitry detects battery operation and activates the voltage boost circuit in advance, preventing the voltage from falling below the minimum operational threshold and extending the usable battery life
4Reliability
If the voltage boost circuitry is always active, then voltage is maintained at adequate levels, but power is wasted boosting voltage when not needed from non-battery sources
Solution Approach 1:
The patent implements dynamics by making the voltage boost circuitry conditional rather than static. The processing circuitry dynamically controls the voltage boost circuit based on real-time detection of the power source type, activating it only when battery power is detected and deactivating it when non-battery power is available, thereby optimizing energy efficiency while maintaining voltage reliability when needed
