USB Socket Connector Adaptability via Shielding Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional USB socket connectors are limited in their range of application due to the metallic shielding cover, which requires specific mating device structures, restricting their development and usage.
Innovation Solution
A touch-controlling device with a USB plug connector and a functional expansion member featuring a columnar housing, circuit board, and expansion board, replacing the metallic shielding cover, allowing for a wider range of applications and incorporating a color capturing function through a processor, color extractor, and light-emitting unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a metallic shielding cover is used in conventional USB socket connectors, then shielding and structural support are provided, but the range of application and development are restricted due to the requirement for specific mating device structures
Solution Approach 1:
The patent removes the metallic shielding cover from the USB socket connector structure, extracting the component that was limiting adaptability. The columnar housing without a metallic shielding cover allows the connector to be applied to various devices including touch-controlling pens, thereby resolving the contradiction between versatility and structural complexity requirements.
2Adaptability or versatility
If a columnar housing replaces the metallic shielding cover, then adaptability to different devices is improved, but shielding effectiveness may be reduced
Solution Approach 1:
The patent introduces an intermediary solution by using a columnar housing with specific internal结构设计 to provide electromagnetic shielding functionality without requiring a traditional metallic shielding cover. The housing works in conjunction with the circuit board and expansion board to achieve both adaptability and shielding effectiveness.
3Adaptability or versatility
If functional modules are added to expand capabilities, then functionality is enhanced, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent divides the USB socket connector into separate functional modules: a columnar housing, a circuit board with USB interface, and an expansion board with additional functionalities. This segmentation allows for independent manufacturing and assembly of each module, reducing overall manufacturing complexity while enhancing functional capabilities through the expansion board.
Solution Approach 2:
The expansion board serves as a universal platform that can accommodate various functional modules (such as color extraction, light emission, touch control) without requiring changes to the basic USB socket connector structure. This multi-functionality approach enables enhanced capabilities while maintaining ease of manufacture through standardized interfaces.

AI summary
A USB socket connector includes a columnar housing, a circuit board, and an expansion board. The columnar housing has a front portion and an opposite rear portion. The columnar housing includes an accommodating slot recessed from the front portion toward the rear portion and a receiving slot recessed on the rear portion and in air communication with the accommodating slot. A cross section of the receiving slot is larger than that of the accommodating slot. The circuit board includes a tongue plate portion arranged on one side thereof and having a USB3.1 Type-C interface. The circuit board is inserted into the accommodating slot, and the tongue plate portion is arranged in the front portion. The expansion board is substantially and perpendicularly connected to an end of the circuit board away from the tongue plate portion, and the expansion board is arranged in the receiving slot.
