Portable Device Vibration Pattern Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In noisy or distracting environments, or for individuals with hearing impairments, existing mobile communication devices lack effective methods to discreetly notify users of important messages or calls without relying on audible ringtones, which can be irritating and not easily recognizable through vibration alone.
Innovation Solution
A method and apparatus that assign a unique vibration pattern to incoming communications based on group identification, using a processor and vibration unit to provide tactile alerts, allowing users to configure different vibration patterns for various groups of contacts and events, enabling discreet notification of urgent calls or messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audible ringtones are used to notify users of incoming communications, then notification effectiveness is improved, but noise-related irritation and disturbance increase
Solution Approach 1:
The patent replaces the acoustic notification system (ringtones) with a mechanical vibration system. The vibration unit generates tactile alerts through controlled vibration patterns, substituting sound-based notification with mechanical motion-based notification, thereby eliminating noise-related irritation while maintaining effective user alerting.
Solution Approach 2:
The patent changes the notification parameter from acoustic frequency and intensity to mechanical vibration characteristics. By varying vibration patterns (amplitude, frequency, duration, sequence), the system provides distinguishable notifications without producing audible sound, thus resolving the contradiction between effective notification and noise avoidance.
2Object-affected harmful factors
If vibration alerts are used to notify users discreetly, then noise-related irritation is reduced, but notification recognizability deteriorates
Solution Approach 1:
The patent segments the vibration notification into distinct temporal and rhythmic patterns. Different communication types (calls, messages, alerts) are represented by unique vibration sequences, durations, and intensities, enabling users to recognize and differentiate between various notification types through tactile perception alone, without audible sound.
Solution Approach 2:
The patent employs dynamic vibration patterns that vary in amplitude, frequency, and temporal structure. The vibration unit can produce diverse tactile signatures through controlled variation of motion parameters, making each notification type uniquely recognizable while maintaining discreet, non-audible operation.
3Loss of information
If multiple vibration patterns are assigned to different communication groups, then notification specificity is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal vibration control system that manages multiple vibration patterns through a single integrated controller. The processor coordinates the vibration unit to execute different pre-programmed patterns based on communication type, providing high notification specificity while centralizing control logic to minimize overall device complexity.
Solution Approach 2:
The patent pre-defines and stores multiple vibration patterns in the device memory before runtime. When a communication is received, the system automatically selects and executes the appropriate pre-configured pattern based on the communication type, eliminating the need for real-time pattern generation and reducing processing complexity while maintaining high notification specificity.

AI summary
In a meeting or group event, people having a portable device, such as a cell phone or pager, may wish to be discretely notified when an important message is received, an urgent call comes in from a selected person or a selected group of people, or to be alerted to an upcoming important event without any audible alert to disturb the meeting or group event. To convey such a notification, a tactile alert is provided by vibrating the portable device according to a unique vibration pattern associated with the received communication. When a communication is received, a group identification (ID) is assigned based on the communication being a member of a classified group of source addresses. The portable device associates the group ID with a unique vibration pattern. To provide the alert, the portable device is vibrated according to the unique vibration pattern.
