Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If voltage is divided into multiple levels for high-speed data transmission, then data transmission speed is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic voltage control by detecting the operational state of data input/output circuits and adjusting the voltage supplied to them accordingly. When circuits are in a low-speed or idle state, the voltage is reduced to minimize power consumption. When high-speed operation is required, the voltage is increased to maintain performance. This dynamic adjustment resolves the contradiction by making power consumption adaptive to actual transmission needs rather than maintaining high voltage continuously.
Solution Approach 2:
The patent changes the voltage parameter based on the operational state of the data input/output circuits. By detecting whether circuits are operating at high speed or low speed, the system adjusts the voltage level accordingly - using higher voltage for high-speed transmission and lower voltage for low-speed or idle states. This parameter change strategy allows the system to maintain high-speed capability when needed while reducing power consumption during normal or idle operation.
2Productivity
If data input/output circuits are always activated for high-speed transmission, then data transmission capability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic activation of data input/output circuits based on actual transmission needs. Instead of keeping all circuits continuously active, the system selectively activates circuits only when data transmission is required and deactivates them during idle periods. This periodic action maintains high data transmission capability when needed while significantly reducing power consumption during non-transmission periods.
Solution Approach 2:
The patent detects the operational state of data input/output circuits in advance and prepares the appropriate voltage level before transmission begins. By detecting whether circuits need to operate at high speed or can operate at low speed, the system preliminarily determines the voltage requirement and activates circuits only when necessary, avoiding continuous operation and reducing overall power consumption.
3Use of energy by moving object
If voltage levels are reduced to save power, then power consumption is reduced, but data transmission speed decreases
Solution Approach 1:
The patent dynamically adjusts voltage levels based on the actual transmission requirements detected by the control circuit. When high-speed data transmission is required, the system supplies higher voltage to maintain performance. When transmission speed requirements are low or circuits are idle, the system reduces voltage to minimize power consumption. This dynamic adjustment ensures that speed is maintained only when necessary, resolving the contradiction between power consumption and transmission speed.
Solution Approach 2:
The patent changes the voltage parameter adaptively based on the operational state of data input/output circuits. The control circuit detects whether circuits are operating at high speed or low speed and adjusts the voltage level accordingly - increasing voltage when high speed is required and decreasing voltage when power saving is prioritized. This parameter change strategy allows the system to optimize the trade-off between power consumption and transmission speed based on actual needs.
