Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods using conductive wires face limitations such as frequency constraints, moisture and debris ingress, and capacitive coupling issues, which hinder efficient data transfer, especially for high-frequency signals like millimeter waves.
Innovation Solution
The use of waveguides with a dielectric core encapsulated by a cladding containing conductive portions allows for determining the orientation of the waveguide, enabling successful data transmission regardless of the waveguide's orientation by sending electrical signals through the cladding, which can compensate for orientation offsets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conductive wires are used for data transmission, then data can be transferred through the conductive wires, but the maximum frequency is limited due to resistance of the conductive material
Solution Approach 1:
The patent replaces conductive wire-based electrical signal transmission with waveguide-based electromagnetic wave transmission. The waveguide uses a dielectric core surrounded by conductive cladding to guide millimeter waves, eliminating the resistance limitations of conductive wires and enabling significantly higher frequency data transmission at tens or hundreds of GHz.
2Productivity
If conductive wires are used for data transmission, then data can be transferred, but receptacles on the receiving side create openings where moisture and debris may enter
Solution Approach 1:
The waveguide uses a hermetic seal structure with a dielectric core and conductive cladding that completely encloses the signal transmission path. This sealed structure eliminates openings that would allow moisture and debris to enter, while still enabling high-frequency electromagnetic wave transmission through the dielectric material.
3Reliability
If shielding solutions are implemented to shield signal lines, then capacitive coupling between wires is avoided, but the shielding solutions are bulky in size
Solution Approach 1:
The patent replaces the need for external shielding solutions with an integrated waveguide structure. The conductive cladding surrounding the dielectric core inherently confines and shields the electromagnetic waves within the waveguide, eliminating capacitive coupling issues without requiring additional bulky shielding components.
4Speed
If waveguides are used for data transmission, then data can be transmitted at high frequencies, but the orientation of the waveguide must match between sending and receiving devices
Solution Approach 1:
The waveguide incorporates multi-functional conductive cladding that serves both as part of the hermetic seal structure and as an orientation detection mechanism. The conductive portions in the cladding can sense the relative orientation between mated waveguides and provide feedback signals, enabling the system to automatically compensate for misalignment and maintain proper signal transmission without requiring precise manual alignment.

AI summary
A waveguide structure to allow device to determine its orientation are disclosed. The waveguide may be formed of a dielectric core and a cladding. The dielectric core may be formed of a solid dielectric material that conducts radio waves at millimeter wave frequencies and above. The cladding may encapsulate the core, and may include at least two conductive portions. Each conductive portion may be disposed around less than the entire core. The conductive portions allow electrical signals to flow between two devices to determine an orientation of the waveguide.
