Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If general-purpose input/output (GPIO) ports are used for data communication between modules, then the apparatus can perform basic data transmission, but the efficiency of data communication is lowered and various communication modes cannot be performed
Solution Approach 1:
The patent applies dynamics by making the communication mode configurable and switchable between different modes (GPIO mode and I2C mode) based on communication requirements. The signal processing device can dynamically select the appropriate communication mode for different data transmission scenarios, allowing the system to adapt between basic and efficient communication needs.
Solution Approach 2:
The patent changes the communication parameter by introducing multiple communication modes (GPIO and I2C) that can be selected based on the specific communication requirements. By changing the communication mode parameter, the system can optimize for either versatility (GPIO) or efficiency (I2C) depending on the situation.
2Productivity
If communication mode switching is implemented between GPIO and I2C modes, then data transmission efficiency is enhanced, but the system complexity increases due to mode management requirements
Solution Approach 1:
The patent applies self-service by implementing automatic communication mode selection and switching within the signal processing device. The device autonomously manages the transition between GPIO and I2C modes based on communication requirements, reducing the burden on external controllers and simplifying the overall system operation despite the multiple modes available.
Solution Approach 2:
The patent makes the signal processing device universal by enabling it to perform multiple communication functions through different modes (GPIO and I2C). This multi-functionality allows the same hardware interface to serve different communication purposes, reducing the need for separate dedicated interfaces for each communication mode.
3Reliability
If multiple communication modes are supported simultaneously, then communication defects are reduced, but the device complexity increases due to additional protocol handling requirements
Solution Approach 1:
The patent uses the signal processing device as an intermediary that handles protocol conversion and management between different communication modes. By centralizing the protocol handling in this intermediate component, the patent isolates the complexity of multiple protocols from the rest of the system while maintaining reliable communication through appropriate mode selection.
