Engineering Contradiction Analysis
1Productivity
If multiple transmission interfaces transmit electrical signals simultaneously with high power, then transmission performance is improved, but power consumption and heat generation increase excessively
Solution Approach 1:
The patent implements dynamic power management by introducing multiple transmission modes (first transmission mode for total power control, second transmission mode for maximum power control, third transmission mode for fast transmission control) that allow the system to adaptively adjust transmission power based on real-time conditions. The control chip dynamically switches between these modes to optimize transmission performance while controlling power consumption, rather than operating at fixed high power levels.
Solution Approach 2:
The patent changes the power transmission parameters by establishing different preset power levels (first preset power for total transmission power, second preset power for maximum transmission power, third preset power for fast transmission interface). These parameter changes enable the system to operate at appropriate power levels for different transmission scenarios, avoiding excessive power consumption while maintaining necessary transmission performance.
2Productivity
If multiple transmission interfaces transmit electrical signals simultaneously with high power, then transmission performance is improved, but heat generation increases excessively
Solution Approach 1:
The control chip dynamically adjusts transmission power through multiple transmission modes to prevent excessive heat generation. By switching between first transmission mode (controlling total power), second transmission mode (controlling maximum power per interface), and third transmission mode (fast transmission with controlled power), the system maintains transmission performance while keeping power dissipation and heat generation within acceptable limits.
Solution Approach 2:
The patent establishes different power parameters (first preset power, second preset power, third preset power) that are optimized to balance transmission performance and heat generation. These parameter changes allow the system to operate at lower power levels when full performance is not required, thereby reducing heat generation while maintaining necessary transmission capabilities.
3Use of energy by moving object
If total transmission power is limited across multiple interfaces, then power consumption is reduced, but transmission performance of individual interfaces may be compromised
Solution Approach 1:
The patent applies local quality control by differentiating between different transmission interfaces and applying different power management strategies. The first transmission mode controls total power across all interfaces, the second transmission mode ensures maximum power for critical interfaces, and the third transmission mode provides fast transmission capability for specific interfaces. This localized quality approach ensures that power-constrained interfaces operate efficiently while critical interfaces maintain necessary performance levels.
Solution Approach 2:
The control chip dynamically allocates power among different interfaces based on real-time transmission needs. By switching between transmission modes and adjusting power distribution dynamically, the system ensures that power consumption is optimized overall while critical transmission interfaces receive sufficient power to maintain performance when needed.

AI summary
An electrical signal transmission method applied to an electrical signal transmission system includes first transmission interfaces and second transmission interface(s). Electrical signal transmission modes of the electrical signal transmission system include: a first transmission mode used for controlling a total transmission power of the first transmission interfaces and the second transmission interface(s) to be less than or equal to a first preset power, and a second transmission mode used for controlling a maximum transmission power of a second transmission interface to be the first preset power. The electrical signal transmission method includes: determining whether the first transmission mode is turned on; if yes, making the total transmission power of the first transmission interfaces and the second transmission interface(s) less than or equal to the first preset power; and if no, making the maximum transmission power of the second transmission interface be a second preset power.
