Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a star topology with coaxial cables is used to connect multiple wireless components to a central transceiver, then signal routing is achieved, but space is consumed and noise is generated
Solution Approach 1:
The patent segments the traditional star topology into multiple daisy-chained connections. Instead of all components connecting to a central transceiver, components are connected in a sequence where each component connects to the next, forming a linear chain. This segmentation reduces the need for multiple separate cable runs from a central point, thereby reducing overall space consumption while maintaining connectivity.
Solution Approach 2:
The patent introduces an intermediary connection method using a shared communication bus that components can tap into. Rather than requiring dedicated coaxial cables from each component to the transceiver, components communicate through this shared bus structure. This intermediary approach significantly reduces cable quantity and space requirements while enabling efficient signal routing.
2Reliability
If coaxial cables and shielded conductors are used to route signals, then signal transmission is achieved, but noise is generated through coupling and reflections
Solution Approach 1:
The patent replaces the traditional electrical coaxial cable system with an optical communication system. Optical fibers transmit signals as light rather than electrical signals, eliminating electromagnetic coupling and reflections that cause noise in electrical systems. This substitution maintains reliable signal transmission while eliminating the harmful electromagnetic noise generated by coaxial cables.
3Adaptability or versatility
If multiple interface connections are implemented in a star topology, then wireless standards are supported, but routing bottlenecks occur
Solution Approach 1:
The patent implements a universal communication bus that all wireless components can access. Instead of requiring separate dedicated interfaces for each wireless standard in a star topology, multiple components share this universal bus. Each component can tap into the bus to communicate with the transceiver, providing multi-functionality and supporting multiple wireless standards without increasing routing complexity.
4Reliability
If coaxial cables are routed throughout the electronic device, then signal connectivity is achieved, but assembly becomes difficult and yield is reduced
Solution Approach 1:
The patent segments the connectivity requirement into modular components that can be independently assembled. Each component in the daisy-chain or bus-based architecture can be assembled and tested separately before being integrated into the final device. This modular segmentation significantly simplifies the assembly process compared to routing multiple coaxial cables through the entire device, improving both assembly ease and manufacturing yield.
