Perpendicular-Axis Socket Fixing for Electronic Device Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power sockets on electronic devices tend to detach from the circuit board after repeated plugging and unplugging, leading to potential short circuits or fires.
Innovation Solution
A socket design featuring a first and second connecting structure along perpendicular connecting axes, which are integrated into a casing, providing enhanced fixing strength and preventing detachment, thereby avoiding contact with the circuit board and minimizing the risk of short circuits or fires.

Engineering Contradiction Analysis
1Ease of manufacture
If the power socket is fixed on a circuit board, then the socket can be easily connected to the device, but the pins may come off the circuit board after repeated plugging and unplugging
Solution Approach 1:
The patent transitions from a single-plane mounting approach to a three-dimensional structure by adding a support block that extends perpendicular to the circuit board. The socket is mounted on this support block rather than directly on the circuit board, creating a spatial separation that prevents stress transmission during plugging and unplugging operations.
Solution Approach 2:
The support block serves as an intermediary component between the circuit board and the power socket. It absorbs the mechanical stress and force generated during plug insertion and removal, preventing these forces from being transmitted to the circuit board and causing pin detachment.
2Strength
If the socket is fixed on the casing with two perpendicular connecting axes, then the fixing strength is enhanced, but the device complexity increases
Solution Approach 1:
The mounting structure is segmented into distinct functional components: the first connecting structure for electrical connection to the circuit board, the support block for structural support, and the second connecting structure for mechanical fixation to the casing. This segmentation allows each component to perform its specific function optimally.
Solution Approach 2:
The patent combines multiple functions into integrated structures. The support block simultaneously provides mechanical support, serves as a mounting platform for the socket, and acts as a stress-absorbing element. The first and second connecting structures are merged with the socket body to form a unified assembly.

AI summary
An electronic device includes a socket and a casing. The socket includes a first connecting structure and a second connecting structure. The casing includes a first side wall and a second side wall, wherein the first side wall is essentially perpendicular to the second side wall. The first side wall includes a third connecting structure and the second side wall includes a fourth connecting structure. The first connecting structure is connected to the third connecting structure along a first connecting axis and the second connecting structure is connected to the fourth connecting structure along a second connecting axis, such that the socket is fixed on the casing, wherein the first connecting axis is essentially perpendicular to the second connecting axis.
