Thin USB Socket Piercing Structure for Space Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional USB sockets are bulky due to their design, which does not conform to the trend of thin electronic devices, as the casing dimensions are larger than the covering component, resulting in increased size and inefficiency in space utilization.
Innovation Solution
A thin-type USB socket design featuring a piercing structure with internal walls that buckle the USB plug, a substrate with integrated circuit and terminals, and additional components like resilient pads, constraining structures, and skidproof components to securely fasten the plug without extra covering components, reducing the socket's thickness and height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional USB socket design with covering component is used, then the USB plug is securely buckled, but the casing dimensions become larger than necessary
Solution Approach 1:
The patent removes the separate covering component from the USB socket design. Instead, the casing itself forms the buckling structure that directly engages with the USB plug, eliminating the need for an additional covering layer and reducing overall casing dimension.
Solution Approach 2:
The patent integrates the buckling function into the casing structure itself. The casing wall includes a buckling portion that directly engages the USB plug, merging the support and buckling functions into a single integrated structure rather than separate components.
2Ease of operation
If a conventional USB socket with separate covering component is used, then the USB plug is constrained, but the socket thickness increases
Solution Approach 1:
The patent eliminates the separate covering component that added to socket thickness. The constraint function is transferred to the casing structure itself, which provides the necessary constraint without the additional thickness of a separate covering layer.
Solution Approach 2:
The patent uses the lateral dimension of the casing wall to provide constraint, rather than adding thickness in the vertical dimension. The buckling portion extends laterally from the casing wall to engage the USB plug, converting a thickness problem into a lateral engagement solution.
3Reliability
If a conventional USB socket design is used, then the USB plug is buckled by covering component, but space utilization in the electronic device becomes inefficient
Solution Approach 1:
The patent removes the covering component that occupied unnecessary space. The buckling function is performed by the casing structure itself, eliminating wasted space between the connecting plank and the buckling structure.
Solution Approach 2:
The patent uses a thin buckling portion formed directly on the casing wall instead of a bulky covering component. This thin-film approach provides the necessary buckling function while minimizing space occupation and improving overall space utilization.

AI summary
A USB socket is disposed on a casing for connecting to a USB plug. The USB socket includes a piercing structure, a substrate and a plurality of terminals. The piercing structure is formed on a surface of the casing, and a main board is disposed inside the casing. An internal wall of the piercing structure can buckle the USB plug when the USB plug inserts into the piercing structure. The substrate is disposed on the main board and located inside the piercing structure. An integrated circuit is disposed on the substrate. The plurality of terminals is disposed on the substrate and coupled to the integrated circuit. The USB plug is electrically connected to the substrate and the terminals when the USB plug inserts into the piercing structure.
