HMD Gendered Connector Assembly for USB Profile Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted devices (HMDs) face compatibility issues with external electronic devices due to varying interface connector profiles, such as the transition from B-type to C-type USB connectors, which affects electrical connections and data transfer rates.
Innovation Solution
The implementation of a compatible gendered connector assembly within the HMD that can accommodate different connection profiles, allowing for the use of either B-type or C-type USB connectors through interchangeable gendered connector assemblies, ensuring secure and efficient electrical connections with external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the HMD uses a fixed connector type (e.g., B-type USB), then the connector structure is simple and manufacturing is easy, but it cannot connect to external devices with different connector profiles (e.g., C-type USB)
Solution Approach 1:
The connector assembly is divided into separate interchangeable components: a base connector body and multiple gendered connector assemblies (male and female connectors of different types). This segmentation allows the HMD to maintain a simple base structure while enabling compatibility with various connector profiles through detachable modules.
Solution Approach 2:
The base connector body is designed as a universal interface that can accommodate multiple types of gendered connector assemblies. This multi-functional design enables the same base structure to work with different connector types (B-type, C-type, etc.), achieving broad compatibility without requiring multiple dedicated connector structures.
2Adaptability or versatility
If the HMD includes multiple connector types simultaneously, then compatibility with different devices is improved, but the device complexity and size increase
Solution Approach 1:
Instead of integrating all connector types into a single bulky assembly, the solution segments connectors into a compact base body and separate detachable gendered assemblies. This allows multiple connector types to be stored separately and attached only when needed, reducing the overall volume when not in use.
Solution Approach 2:
The connector assembly transitions from a static fixed-connector design to a dynamic interchangeable system. The detachable nature of the gendered connector assemblies allows the HMD to adapt its connector configuration based on the external device being connected, optimizing space utilization while maintaining versatility.
3Ease of operation
If the connector assembly is designed for easy interchangeability, then ease of operation is improved, but the reliability of electrical connection may be compromised
Solution Approach 1:
The guide pins and guide grooves are pre-configured in the base connector body and gendered assemblies to automatically align components during insertion. This preliminary positioning action ensures proper alignment before electrical contact is made, maintaining connection reliability while enabling easy user interchangeability.
Solution Approach 2:
The guide pins and guide grooves act as intermediary elements that facilitate the connection process. These mechanical guides mediate between the user's simple insertion action and the complex requirement for precise electrical contact alignment, ensuring reliable connections without requiring complex user manipulation.
