Solution Overview

Problem

Existing game controller button structures suffer from gaps that affect operating hand feeling and are costly due to the use of metal buttons with poor rebound effects.

Innovation Solution

A button structure comprising a push button with elastic arms, a housing, and a supporting unit, where the elastic arms have arc portions to enhance tactile feedback and stability, and a housing with stopping blocks to prevent deformation, while using a cost-effective design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a metal button is used on the circuit board to provide feedback force, then the operating hand feeling is improved, but the manufacturing cost increases and the rebound effect deteriorates

Engineering Contradiction:
Improveoperating hand feelingVSAvoidmanufacturing cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent creates a copy of the metal button's feedback function using plastic material with integrated elastic arms. Instead of using an actual metal button, the invention fabricates a plastic push button with elastic arms that replicate the tactile feedback mechanism, thereby achieving similar operating hand feeling while reducing manufacturing cost and improving rebound effect.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent uses composite construction by integrating multiple functional elements into a single plastic push button structure. The elastic arms are formed as integral parts of the plastic button body, combining the functions of button head, spring mechanism, and contact element into one composite component made from plastic material with embedded elastic elements.

Inventive Principle:
Principle #40Composite materials

2Force

If a metal button is used on the circuit board, then the feedback force is provided, but the rebound effect deteriorates

Engineering Contradiction:
Improvefeedback forceVSAvoidrebound effect
Core Design Contradiction:
ForceVSReliability

Solution Approach 1:

The patent changes the material parameter from metal to plastic with elastic arms, and modifies the structural parameter by designing arched elastic arms with specific geometry. The elastic arms are configured with arches that have optimized curvature and thickness to provide both the necessary feedback force and superior rebound effect compared to traditional metal buttons.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If a D-pad with metal button is used, then the operating feedback is improved, but gaps are caused affecting the hand feeling

Engineering Contradiction:
Improveoperating feedbackVSAvoidgap between D-pad and button
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent merges the button head and elastic arms into a single integrated plastic component. The elastic arms are formed as integral extensions from the button head body, eliminating the need for separate metal button assembly. This integration ensures precise fit between the D-pad and button structure, eliminating gaps while maintaining operating feedback.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A button structure includes a push button, a housing enclosing the push button, a supporting unit and a circuit board. The push button has an outer wall. Several portions of a bottom of the outer wall extend outward to form a plurality of projection parts evenly distributed around the outer wall. Each projection part extends along a radial direction of the outer wall. One side of each projection part extends outward and along a circumferential direction of the push button to form an elastic arm. A middle of the elastic arm is arched outward and opposite to the outer wall. The supporting unit is mounted inside the push button. The push button is disposed on an upper surface of the circuit board. The housing is disposed on the upper surface of the circuit board. The supporting unit is fastened between the circuit board and the push button.
