Solution Overview
Problem
Existing game controllers suffer from mechanical instability due to mechanical instability and mechanical instability, and mechanical instability, and mechanical instability, and mechanical failure, resulting in poor performance and reliability.
Innovation Solution
A button structure with a push button, a supporting unit, and a circuit board, where the supporting unit includes a main body, fixing rods, side arms, and buckling hooks, which are designed to securely attach to the circuit board, preventing shaking and facilitating stable assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a supporting column is used to fix the D-pad to the circuit board, then the location and fixation between the D-pad and circuit board are realized, but the D-pad still wobbles due to tolerances between the supporting column and circuit board
Solution Approach 1:
The supporting column is divided into multiple segments: a first supporting column portion that contacts the circuit board, a second supporting column portion that extends upward, and a cap portion that covers the top. This segmentation allows each part to perform its specific function - the first portion provides stable base contact, the second portion provides fixation, and the cap portion provides protection and additional support surface.
Solution Approach 2:
The supporting column structure is pre-designed with specific geometric features including tapered portions, rounded corners, and precise dimensional relationships between components. These preliminary design actions ensure that when assembled, the D-pad achieves stable fixation without wobbling, eliminating the need for post-assembly adjustments.
2Device complexity
If a simple supporting column structure is used, then the device complexity is reduced, but the fixation stability and anti-wobble performance deteriorate
Solution Approach 1:
The supporting column is segmented into distinct functional portions (first supporting column portion, second supporting column portion, cap portion) that work together to provide stable fixation. This segmentation achieves high reliability without requiring complex external components or assembly procedures.
Solution Approach 2:
The supporting column integrates multiple functions into a single unified structure: mechanical support, electrical isolation, positional alignment, and wobble prevention. By merging these functions into one component rather than using separate elements, the design achieves high fixation stability while maintaining relatively simple device complexity.

AI summary
A button structure includes a push button, a supporting unit mounted inside the push button, and a circuit board. The supporting unit has a main body. Two opposite sides of the main body extend outward to form two side arms. The main body extends downward to form a fixing rod. A front and a rear of a lower portion of an outer surface of the fixing rod protrude outward to form two buckling hooks. The push button is disposed on an upper surface of the circuit board. The circuit board has a through hole penetrating through the upper surface and a lower surface of the circuit board. The fixing rod passes through the through hole. The two buckling hooks are buckled to the lower surface of the circuit board. The circuit board is fastened among the main body, the two side arms and the two buckling hooks.
