Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an electronic fuse is used to modify the function of an integrated circuit, then the adaptability of the circuit can be improved, but the power consumption increases significantly
Solution Approach 1:
The patent combines an electronic fuse and an interface fuse into a single integrated chip. The electronic fuse operates in a first working mode with higher power consumption for function modification, while the interface fuse operates in a second working mode with lower power consumption for interface configuration. This merging allows the system to switch between modes based on power availability, resolving the contradiction between adaptability and power consumption.
Solution Approach 2:
The patent introduces dynamic operation modes that allow the chip to switch between electronic fuse mode and interface fuse mode based on power conditions. The controller can selectively activate either the electronic fuse or interface fuse depending on whether sufficient power is available, making the system adaptable to varying power constraints while maintaining the ability to modify functions when needed.
2Adaptability or versatility
If only an electronic fuse is provided on the chip, then function modification capability is achieved, but the operable range is limited by power constraints
Solution Approach 1:
The integrated chip provides multiple functions through a single device: it can operate as an electronic fuse for function modification, as an interface fuse for interface configuration, or in combination modes. This multi-functionality expands the operable range beyond what a single fuse type could provide, allowing the chip to adapt to different application scenarios including low-power and high-power environments.
Solution Approach 2:
The patent changes operational parameters by introducing two distinct working modes with different power characteristics. The controller monitors power conditions and adjusts which fuse mechanism is active, thereby changing the operational parameters of the chip to match available power levels and expand the range of operable conditions.
3Device complexity
If the electronic fuse is integrated within a single chip, then device integration is improved, but the complexity of managing multiple fuse modes increases
Solution Approach 1:
The controller automatically monitors power conditions and selectively activates the appropriate fuse mode without requiring manual intervention. The system self-manages the complexity of coordinating between electronic fuse and interface fuse operations, making the integrated chip easy to operate while maintaining high integration. The controller handles the decision-making process, freeing users from managing the complexity of multiple fuse modes.

AI summary
An integral multifunction chip is provided. The integral multifunction chip includes an electronic fuse and an interface fuse. The interface fuse and the electronic fuse are disposed in parallel and integrated in a single chip. In a case where only a single chip is provided, the integral multifunction chip of the present disclosure can be selectively operated in a working mode of the electronic fuse or the interface fuse, so that convenience of use of the integral multifunction chip can be improved.
