Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current input devices, such as those using eccentric rotating mass (ERM) motors for haptic feedback, are limited in providing a wide range of haptic experiences as they can only adjust intensity and not frequency, failing to fully immerse users in gaming applications.
Innovation Solution
An information handling system determines gaming context characteristics to control a linear magnetic ram module in input devices, enabling the generation of wide-band haptic feedback with variable frequency and intensity, including tachammer mode chassis impacts, to enhance user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If ERM motors are used for haptic feedback, then the device structure is simple, but the haptic feedback frequency range is limited
Solution Approach 1:
The patent replaces the traditional mechanical ERM motor system with a linear magnetic ram module that uses electromagnetic fields to drive a magnet linearly. This substitution enables precise control over both frequency and intensity of haptic feedback, resolving the contradiction by achieving wide-band frequency control without the mechanical limitations of rotating mass systems.
Solution Approach 2:
The patent changes the fundamental operating parameters of the haptic actuator by using a linear magnetic ram that can independently vary frequency and intensity parameters. Unlike ERM motors that are fixed in frequency, the linear magnetic ram module can dynamically adjust both frequency and intensity parameters to provide diverse haptic effects across a wide frequency spectrum.
2Ease of manufacture
If ERM motors are used for haptic feedback, then the manufacturing cost is low, but the haptic feedback variety is limited
Solution Approach 1:
The linear magnetic ram module serves multiple functions: it can generate various types of haptic effects (vibrations, impacts, pulses), control frequency across a wide spectrum, and adjust intensity independently. This multi-functionality allows a single device to replace what would traditionally require multiple specialized actuators, achieving haptic feedback variety while maintaining manufacturing efficiency.
3Adaptability or versatility
If linear magnetic ram module is used for wide-band haptic feedback, then the haptic feedback variety increases, but the control complexity increases
Solution Approach 1:
The patent implements control systems that monitor and adjust the linear magnetic ram module operation in real-time. By incorporating feedback mechanisms, the system can automatically optimize frequency and intensity parameters based on the desired haptic effect, reducing the manual control complexity while maintaining the ability to generate diverse haptic feedback varieties.
