Solution Overview

Problem

Existing electronic devices provide limited and intuitive vibration feedback, as they can only generate a single type of vibration based on a single frequency, making it difficult to distinguish between various notification situations.

Innovation Solution

An electronic device with a vibration-generating device that supports multiple frequencies, using a processor to select and set vibrations based on musical elements, generating patterns that incorporate multiple frequencies to provide a more dynamic and varied vibration feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single frequency is used for vibration, then the device structure is simple, but the vibration feedback is not intuitive and cannot represent various situations

Engineering Contradiction:
Improvevibration generation structureVSAvoidnotification information
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent segments the vibration feedback into multiple frequency components. Instead of using a single frequency, the system divides the vibration into multiple frequencies (e.g., first frequency, second frequency, third frequency) that can be independently controlled and combined to represent different notification types, thereby encoding more information without requiring complex hardware

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from one-dimensional single-frequency vibration to multi-dimensional vibration by introducing frequency as an additional dimension of variation. By combining multiple frequencies with different intensities and patterns, the system creates a richer vibration space that can distinguish between various notification situations (call, message, alarm, etc.)

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of information

If multiple frequencies are used for vibration, then the vibration feedback becomes intuitive and can represent various situations, but the device complexity increases

Engineering Contradiction:
Improvenotification informationVSAvoidvibration generation structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent makes the existing vibration motor multi-functional by enabling it to generate multiple frequencies simultaneously. The same motor structure is used, but through sophisticated control of drive signals at different frequencies, it can produce diverse vibration patterns that represent various notification types, eliminating the need for separate vibration motors for each frequency

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

Solution Approach 2:

The patent changes the operational parameters of the vibration motor by varying the drive signal frequencies and intensities. By adjusting frequency parameters (first frequency, second frequency, third frequency) and their corresponding intensities, the system creates distinguishable vibration patterns without modifying the physical structure of the motor itself

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If only intensity adjustment is used, then the control is simple, but the vibration patterns are limited and cannot provide distinct feedback for different situations

Engineering Contradiction:
Improvevibration controlVSAvoidvibration pattern variety
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent introduces dynamic control by varying not only the intensity but also the frequency of vibrations over time. The system dynamically adjusts multiple parameters (frequency, intensity, duration) to create adaptive vibration patterns that can respond to different notification situations, making the feedback both easy to control and highly versatile

Inventive Principle:
Principle #15Dynamics
