Double-Ended Slide Rail for Universal Left-Right Gamepad Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gamepads require separate mold making for left and right slide rails, leading to high manufacturing costs, and unilateral slide rails are prone to loosening and require replacement of integrated PCBs, increasing maintenance costs and affecting service life.
Innovation Solution
A double-ended slide rail design with symmetrically arranged slide rails on both sides of a base, allowing universal assembly for left and right gamepads, eliminating the need for separate molds and integrated circuitry, and featuring a robust structure to prevent loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate mold making is required for left and right slide rails, then the slide rails can be customized for specific sides, but the manufacturing cost increases
Solution Approach 1:
The slide rail is designed with symmetric structure allowing the same component to be used on both left and right sides of the gamepad. The mounting groove and guide pin configuration enables universal installation orientation, eliminating the need for separate left and right mold versions while maintaining side-specific functionality
2Reliability
If the slide rail is integrated with the PCB circuit board, then signal transmission is ensured, but the maintenance cost increases when the slide rail is damaged
Solution Approach 1:
The slide rail is designed as a separate mechanical component independent from the PCB circuit board. The mounting groove structure allows the slide rail to be installed and removed separately from the PCB, enabling replacement of only the damaged slide rail component while preserving the PCB and other functional elements
3Device complexity
If a unilateral slide rail with thin structure is used, then the device complexity is reduced, but the slide rail loosens after long-term use affecting service life
Solution Approach 1:
The design merges two slide rail structures into a single integrated base component with dual symmetric mounting grooves. This combined structure distributes mechanical stress across both sides simultaneously, preventing the loosening issues experienced by unilateral thin structures while maintaining overall structural simplicity

AI summary
The present application discloses a double-ended slide rail and a gamepad, which comprises a base, wherein two sides of the base are respectively provided with slide rails, the two slide rails are symmetrically arranged along the axial direction of the base and have the same structure, and wherein the slide rail on either side is used for connecting with the gamepad, and the slide rail on the other side is used for sleeve-connecting with an equipment host or the slide rail; a mounting groove, which is arranged at one end of the slide rail, wherein the surface of the mounting groove is provided with a guide mark, the back of the mounting groove is provided with a guide pin, and the guide pins of the two slide rails are in contact connection; a limit key, which is arranged at one end of the base. According to the double-ended slide rail and the gamepad, the slide rails on both sides of the base have the same structure and can be connected with the left and right ends of the gamepad, so that two sets of molds need not be produced corresponding to the left and right sides, and the manufacturing cost is saved. Furthermore, the double-ended slide rail does not contain a circuit part, so the circuit does not need to be replaced in the maintenance process, thus reducing the maintenance cost. Because the base adopts a double-sided slide rail structure, it has higher structural strength and is not easy to loosen after long-term use compared with a single slide rail structure.
