Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless signals and image signals are separately collected and processed using separate distributed units and camera modules, then signal processing quality is maintained, but installation area and installation cost increase
Solution Approach 1:
The patent combines wireless communication functionality and image processing functionality into a single distributed unit. The distributed unit includes both a wireless circuit for signal processing and a camera for image capture, allowing both functions to be performed at the same location and transmitted through a single fiber optic line to the central unit, thereby reducing installation area while maintaining processing quality
Solution Approach 2:
The distributed unit is designed as a multi-functional device that performs both wireless signal reception/transmission and image signal capture. This universal device eliminates the need for separate dedicated units for each function, reducing the overall installation area and infrastructure requirements while maintaining the reliability of both signal processing functions
2Adaptability or versatility
If wireless signals and image signals are separately collected and processed, then functional independence is maintained, but installation cost increases due to multiple fiber optic lines
Solution Approach 1:
The patent merges wireless signal transmission and image signal transmission into a single fiber optic line. The distributed unit transmits both types of signals through one connection to the central unit, which then performs separate processing for each signal type, thereby maintaining functional independence while reducing installation cost by eliminating the need for multiple separate fiber optic lines
Solution Approach 2:
The patent segments the signal processing functions at the central unit level, where wireless signal processing and image signal processing are handled by separate circuits (wireless circuit and image processing circuit respectively). This allows functional independence to be maintained in the processing stage while the transmission stage uses a shared fiber optic line, reducing installation cost
3Reliability
If separate distributed units and camera modules are installed, then dedicated processing for each signal type is achieved, but the number of required lines increases
Solution Approach 1:
The patent combines multiple transmission lines into a single fiber optic line that carries both wireless signals and image signals from the distributed unit to the central unit. The central unit then separates and processes each signal type using dedicated circuits, achieving both line reduction and dedicated processing capability
Solution Approach 2:
The distributed unit acts as an intermediary that captures both wireless signals and image signals locally and transmits them through a single fiber optic line to the central unit. The central unit then serves as another intermediary that separates the combined signal stream and routes each signal type to its dedicated processing circuit, thereby reducing the number of required lines while maintaining dedicated processing
