Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual board design is used for each host processor MIPI receiver architecture, then the interface can be customized for specific processor requirements, but manufacturing cost increases and manufacturing complexity increases
Solution Approach 1:
The patent implements a universal MIPI receiver interface design that can handle both 2-lane and 4-lane configurations through a single board architecture. The system uses a lane selection mechanism that allows the same hardware platform to interface with different camera sensor types (2-lane CSI-2 or 4-lane CSI-2) without requiring custom board designs, thereby reducing manufacturing costs while maintaining adaptability.
Solution Approach 2:
The system dynamically configures the MIPI receiver interface by selecting between 2-lane and 4-lane modes based on the connected camera sensor type. The lane selection logic allows the interface to adapt its operational characteristics (number of active lanes, data formatting) according to the specific sensor requirements, enabling a single board design to serve multiple processor architectures.

Solution Approach 2:
The patent combines multiple interface capabilities (2-lane and 4-lane support) into a single unified receiver interface. By merging the functionality of handling different lane configurations into one interface design, the system eliminates the need for separate board designs for different processor architectures, thereby reducing overall device complexity.
3Device complexity
If conventional MIPI receiver interface is used, then simple hardware design is maintained, but the system cannot support different data formats from multiple sensors
Solution Approach 1:
The system dynamically configures the MIPI receiver interface by selecting between 2-lane and 4-lane modes based on the connected camera sensor type. The lane selection logic allows the interface to adapt its operational characteristics (number of active lanes, data formatting) according to the specific sensor requirements, enabling a single board design to serve multiple processor architectures.
Solution Approach 2:
The system changes operational parameters (lane configuration, data format) of the MIPI receiver interface based on the connected sensor type. By dynamically adjusting these parameters rather than requiring hardware changes, the system supports multiple data formats and sensor configurations while maintaining relatively simple hardware design.

AI summary
A system for camera serial interface lane implementation between camera sensor and host processor is disclosed. An input data receiving unit receives first input signal from a first camera sensor in at least one of a two-lane camera serial interface configuration (CSI) or a four-lane CSI configuration; receives second input signal from a second camera sensor in the two-lane CSI. A data selector device selecting a first port for forwarding input signal when the first input signal is received in the two-lane CSI, selecting a second port for forwarding the input signal when the first input signal is obtained in the four-lane CSI configuration. A host processor block including a first receiver block to generate a first output signal when the first input signal is received from the first port, a second receiver block generates a second output signal when the first input signal is obtained from the second port.
