Problem
Existing plug adapters fail to provide a simple and functionally reliable transition between electrical interfaces of different geometric designs, limiting their versatility and efficiency in signal transmission.
Innovation Solution
A plug adapter design featuring a first electrical interface with a circular or elliptical outer conductor and inner conductor parts arranged in a circular line, and a second interface with a rectangular or polygonal outer conductor and inner conductor parts arranged in a straight line, allowing for improved signal transmission through continuous shielding and direct electrical connections without a circuit board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a circuit board is used to connect HSD and USB board connectors, then electrical connection is achieved, but device complexity increases
Solution Approach 1:
The patent merges the HSD and USB connector interfaces into a single integrated adapter body. The first inner conductor parts (HSD contacts) and second inner conductor parts (USB contacts) are directly connected through the adapter housing without requiring a separate circuit board, thereby eliminating an entire component and reducing overall device complexity while maintaining reliable electrical connection.
Solution Approach 2:
The patent extracts and eliminates the circuit board from the adapter assembly. By directly integrating the conductor parts into the adapter housing and establishing direct electrical pathways between HSD and USB contacts, the design removes the intermediary circuit board component, simplifying the overall structure while preserving electrical connectivity.
2Reliability
If inner conductor parts are connected via circuit board, then electrical connection is established, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple functions into the adapter housing itself: mechanical support, electrical connection pathway, and signal transmission medium. By integrating the conductor parts directly into the housing and eliminating the circuit board, the design reduces the number of components that need to be manufactured, sourced, and assembled, thereby lowering overall production costs while maintaining reliable electrical connection.
Solution Approach 2:
The patent removes the circuit board from the bill of materials and assembly process. This extraction eliminates the costs associated with PCB manufacturing, component mounting, and board assembly, while the direct integration of conductor parts into the housing provides a more cost-effective manufacturing approach through reduced part count and simplified assembly.
3Ease of manufacture
If outer conductor parts are formed separately, then assembly is possible, but signal transmission quality decreases
Solution Approach 1:
The patent merges the first outer conductor part and second outer conductor part into a single continuous outer conductor structure formed as one piece with the adapter housing. This continuous shielding structure provides uninterrupted electromagnetic shielding along the signal path between HSD and USB contacts, significantly improving signal transmission quality by preventing electromagnetic interference while maintaining ease of manufacture through integrated forming.
4Reliability
If inner conductor parts are formed integrally, then signal transmission improves, but adaptability decreases
Solution Approach 1:
The patent applies local quality by forming different inner conductor part configurations in different regions of the adapter. The first inner conductor parts are arranged in a circular pattern for HSD interface compatibility, while the second inner conductor parts are arranged in a rectangular pattern for USB interface compatibility. This region-specific conductor arrangement allows integral formation for signal integrity while maintaining adaptability to different interface standards through localized geometric variations.
Solution Approach 2:
The patent employs asymmetry in the conductor part arrangements to accommodate different interface standards. The HSD side features a circular conductor pattern while the USB side features a rectangular conductor pattern. This asymmetric design within the integral structure enables compatibility with both circular and rectangular interface geometries simultaneously, maintaining versatility while achieving improved signal transmission through continuous conductor paths.
