Solution Overview

Problem

Conventional vibration devices struggle to simultaneously present both tactile and pseudo force sensations to users, lacking a comprehensive method to effectively combine these sensations.

Innovation Solution

A vibration control apparatus and method that acquires and combines pseudo force sensory vibration data and tactile sensory vibration data to generate synchronized vibrations, using a vibration mechanism like a linear resonance actuator or voice coil motor, allowing the device to present both sensations to the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a vibration device vibrates according to a particular vibration waveform to present pseudo force sensation, then the user feels a pseudo force sensation, but the device cannot simultaneously present tactile sensation

Engineering Contradiction:
Improveability to present both tactile and pseudo force sensationsVSAvoidcomplexity of vibration control system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the vibration control into two distinct data acquisition sections: one for pseudo force sensory vibration data and another for tactile sensory vibration data. This segmentation allows the system to independently acquire and process different types of vibration data, which are then combined by the vibration control section to achieve both tactile and pseudo force sensations simultaneously without excessive complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The vibration device is designed with multi-functionality to present both tactile sensations and pseudo force sensations through a single device. The vibration mechanism can operate in multiple modes by receiving different vibration waveforms, allowing it to serve dual purposes without requiring separate dedicated devices for each sensation type

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

2Adaptability or versatility

If the vibration mechanism generates vibration based on both pseudo force sensory vibration data and tactile sensory vibration data, then both sensations are presented to the user, but the control system becomes more complex

Engineering Contradiction:
Improvecapability to generate combined vibration sensationsVSAvoidcomplexity of data acquisition and control system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the pseudo force sensory vibration data and tactile sensory vibration data in the vibration control section. Both types of vibration data are acquired separately and then combined into a unified vibration waveform that the vibration mechanism can execute, allowing simultaneous presentation of both sensations through a coordinated approach rather than separate systems

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The vibration control section acts as an intermediary that receives and processes both pseudo force sensory vibration data and tactile sensory vibration data. It mediates between the two data sources, combining them appropriately and generating the final control signals for the vibration mechanism, thereby simplifying the overall system architecture

Inventive Principle:
Principle #24Intermediary (Mediator)
