Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a high-power generator is used to meet peak power demand, then the power supply capability is sufficient, but the weight increases significantly
Solution Approach 1:
The patent applies dynamic power supply by switching between generator and battery based on real-time power demand. The controller adjusts the power supply configuration dynamically: using generator during high-power scanning operations and battery during low-power standby periods, thereby avoiding the need for a continuously running high-power generator and reducing overall system weight requirements
Solution Approach 2:
The patent combines generator and battery into a hybrid power supply system. The generator and battery work cooperatively under controller management, with the battery serving as a buffer that supplements the generator output during peak demand and stores excess energy during low-demand periods, achieving both sufficient power capability and reduced weight
2Power
If a high-power generator is used to meet peak power demand, then the power supply capability is sufficient, but energy waste increases due to low utilization rate
Solution Approach 1:
The patent implements periodic switching between power supply modes. The controller periodically assesses power demand and switches between generator-driven mode during scanning operations and battery-driven mode during standby periods. This periodic action ensures the generator operates only when necessary, eliminating continuous operation waste while maintaining power supply capability
Solution Approach 2:
The patent ensures continuous useful action through the battery buffer. During generator operation, the battery charges simultaneously, storing energy for future use. During battery operation, it maintains power supply without generator intervention. This continuous coordination eliminates idle generator operation and ensures energy is always productively utilized
3Power
If a high-power generator is used to meet peak power demand, then the power supply capability is sufficient, but vibrations increase affecting imaging quality
Solution Approach 1:
The patent extracts the harmful vibration source by separating high-power generation from the mobile detection system. The battery takes over during standby periods when no power is needed, eliminating generator vibrations entirely during these periods. The generator operates only during brief scanning moments when vibrations have minimal impact on imaging quality
Solution Approach 2:
The patent dynamically controls generator operation to minimize vibration impact. The controller activates the generator only during actual scanning operations when the system is in motion, rather than keeping it running continuously. This dynamic switching reduces cumulative vibration exposure and protects imaging quality during critical stationary periods
4Power
If a high-power generator is used to meet peak power demand, then the power supply capability is sufficient, but noise increases affecting operator experience
Solution Approach 1:
The patent removes the noise source from the operational environment by using the battery during standby periods when the system is stationary. The generator, which produces loud noise during operation, is activated only during brief scanning moments when operators are not in immediate proximity, effectively extracting noise from the operator experience
Solution Approach 2:
The patent implements periodic generator operation synchronized with scanning cycles. The generator runs only during active scanning when noise impact is minimized, and remains off during extended standby periods when operators work in quiet conditions. This periodic action pattern separates power generation noise from operator working hours
