Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If signals are injected inductive style on multiple conductors to enhance transmission capacity, then communication performance is improved, but the complexity of the injection device increases
Solution Approach 1:
The injection device is divided into multiple independent inductive couplers, each responsible for injecting signals on specific conductors. Each coupler can be configured separately to handle different injection modes (differential, common, pseudo-differential) on different conductor pairs, allowing modular scaling without requiring a completely complex monolithic device
Solution Approach 2:
Each inductive coupler is designed to perform multiple functions: it can inject signals in differential mode, common mode, or pseudo-differential mode depending on the configuration. The same coupler structure can serve multiple injection purposes by adjusting the winding connections and orientations, reducing the need for separate dedicated injection devices for each mode
2Reliability
If orthogonal multi-injection modes are implemented on multiple conductors, then signal interference is reduced, but the device structure becomes more complex
Solution Approach 1:
Each inductive coupler is locally optimized for specific injection modes on specific conductor pairs. The winding configurations, orientations, and connection patterns are tailored to achieve orthogonal injection for the local conductor pair, ensuring minimal interference. This localized optimization allows the overall system to achieve high reliability without requiring uniform complexity throughout the entire device
Solution Approach 2:
Instead of trying to achieve orthogonal injection through complex signal processing or multiple separate injection devices, the invention inverts the approach by using simple inductive couplers with carefully configured windings that naturally produce orthogonal modes. The complexity is inverted from the signal processing domain to the physical configuration domain, where geometric arrangements of windings create the desired orthogonal properties
3Productivity
If multiple inductive couplers are used for orthogonal injection, then transmission capacity increases, but the number of components and assembly complexity increases
Solution Approach 1:
Multiple inductive couplers are merged into a single integrated assembly where the conductors pass through multiple couplers in sequence. The couplers are positioned close together and share common conductor paths, allowing them to be manufactured and assembled as one unit rather than separate components. This merging reduces the overall number of discrete parts and simplifies assembly while maintaining the functionality of multiple independent injection points
