Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a transmission interface module is disposed between the camera module and the processor for pre-processing image signals, then image processing capability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic power management by allowing the transmission interface module to switch between different operation modes (first operation mode with full processing capability and second operation mode with reduced processing capability). This enables the system to adapt power consumption to actual processing needs, improving image processing capability when required while reducing power consumption during normal operation.
Solution Approach 2:
The patent changes the operational parameters of the transmission interface module by defining multiple operation modes with different processing capabilities. The module can transition between these modes based on system requirements, effectively changing its power consumption and processing performance parameters to resolve the contradiction between capability and energy usage.
2Productivity
If a transmission interface module is disposed between the camera module and the processor, then image signal pre-processing is improved, but heat dissipation increases
Solution Approach 1:
The dynamic switching between operation modes allows the module to adjust its processing intensity and corresponding heat generation. During normal operation, the module operates in the lower-power second mode with reduced heat dissipation. When high-performance pre-processing is needed, it temporarily switches to the first mode, thus improving signal processing capability while controlling overall heat dissipation.
3Adaptability or versatility
If multiple operation modes are implemented in the transmission interface module, then power consumption flexibility is improved, but device complexity increases
Solution Approach 1:
The transmission interface module is designed with multi-functionality by incorporating multiple operation modes within a single device. This allows the module to perform both high-performance processing and low-power operation without requiring separate hardware components, thereby improving power consumption flexibility while avoiding excessive device complexity through integrated design.
