Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If dielectric waveguides are used to guide electromagnetic rays over transmission lengths of 10 to 15 meters, then the data transmission capability is enabled, but the signal strength deteriorates due to attenuation in the waveguides and plug connections
Solution Approach 1:
The patent changes the physical parameters of the plug connection by using a radiation source positioned at the end of the dielectric waveguide rather than a traditional connector. This parameter change in the coupling mechanism reduces electromagnetic losses at the connection point, thereby maintaining signal strength over the required transmission length of 10 to 15 meters
Solution Approach 2:
The patent introduces a receiving unit as an intermediary component that optimizes the coupling between the radiation source and the dielectric waveguide. This intermediary element enables efficient energy transfer and reduces transmission losses, allowing the system to maintain minimum signal strength requirements over extended transmission distances
2Loss of energy
If the number of electromagnetic couplings is reduced by using receiving units to align and fix dielectric waveguides, then transmission losses are reduced, but the device complexity increases due to the need for precise alignment and fixation mechanisms
Solution Approach 1:
The patent merges the alignment and fixation functions into the receiving unit itself, which is designed to automatically position and secure the dielectric waveguide in the optimal orientation relative to the radiation source. This integration reduces the need for separate alignment mechanisms and simplifies the overall device structure while minimizing transmission losses
