Solution Overview

Problem

Conventional button mechanisms on video game console and computer controllers provide only a single stroke of press, limiting the ability to create different tactile sensations in various operational scenarios.

Innovation Solution

A button mechanism incorporating a magnet, coils, and a vibrator, where magnetic fields and vibrations are used to position the button element in multiple positions, providing distinct tactile feedback through a series of strokes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional button mechanism with a single stroke of press is used, then the structure is simple, but the tactile sensation variety is limited

Engineering Contradiction:
Improvetactile sensation varietyVSAvoidbutton mechanism structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The button mechanism is segmented into multiple functional components: a button element, a magnet, multiple coils (first coil, second coil, third coil), and a vibrator. Each component serves a specific function in achieving multi-position positioning and tactile feedback, transforming a simple single-stroke button into a complex multi-functional system that provides varied tactile sensations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The button mechanism achieves multi-functionality by integrating multiple coils that can independently generate magnetic fields to position the button element at different positions (first, second, and third positions). The vibrator adds another function by providing haptic feedback. This universal design allows a single button to serve multiple purposes: positioning at different depths and providing tactile feedback, thereby increasing tactile sensation variety without requiring multiple separate buttons.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple coils and a vibrator are added to enable multiple strokes and vibrations, then the tactile sensation variety is improved, but the device complexity increases

Engineering Contradiction:
Improveoperational feedback experienceVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple functional elements into a compact integrated structure. The first, second, and third coils are arranged around the hollow tube at different positions, working together to control the magnet and button element. The vibrator is integrated into the assembly, connected through the hollow tube. This merging of components into a unified multi-stroke button mechanism reduces the need for separate buttons for different functions, thereby improving operational feedback experience while managing device complexity through intelligent integration.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A button mechanism is provided, including a button element, a magnet connected to the button, a hollow tube, a first coil, and a second coil. The first and second coils are disposed on the tube. When the first coil generates a first magnetic field, the magnet is magnetically attracted by the first coil, and the button element is positioned in the first position. When the second coil generates a second magnetic field, the magnet is attracted by the second coil, and the button element is positioned in the second position.
