Solution Overview

Problem

Electrically heated smoking systems provide limited and confusing feedback to users, often disturbing others and failing to convey timely information, leading to a diminished user experience due to reliance on auditory and visual signals that may be obscured or distracting.

Innovation Solution

Incorporating a plurality of haptic output elements that convey information through tactile feedback, allowing for targeted and discreet communication with the user, regardless of their interaction with the device, to enhance user experience and minimize disturbance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If auditory and visual signals are used to provide feedback to users, then information can be conveyed to the user, but the feedback may be obscured, distracting, or disturbing to others

Engineering Contradiction:
Improvefeedback informationVSAvoiddisturbance to others and user confusion
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces auditory and visual feedback systems with a haptic feedback system using vibration motors. The control circuit is configured to activate vibration motors to provide tactile feedback to the user, substituting the mechanical vibration mechanism for the acoustic and optical feedback systems that cause obscuration and disturbance.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces vibration motors as an intermediary mechanism between the control circuit and the user. These motors convert electrical signals into tactile vibrations that the user can feel, serving as a mediator that conveys information without the harmful effects of auditory and visual signals.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If multiple output elements are used to convey different functionalities, then comprehensive feedback can be provided, but the feedback becomes confusing for the user

Engineering Contradiction:
Improvefeedback informationVSAvoiduser interpretation of feedback
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent divides the feedback system into multiple independent vibration motors distributed at different locations on the device. Each vibration motor can be independently controlled to provide specific tactile feedback, allowing the system to convey different types of information through spatially distinct vibration patterns rather than using multiple confusing output elements.

Inventive Principle:
Principle #1Segmentation

3Loss of information

If visual signals are continuously displayed during waiting times, then users can be informed of device status, but the signals may be distracting for others nearby

Engineering Contradiction:
Improvedevice status informationVSAvoiddistraction to others
Core Design Contradiction:
Loss of informationVSObject-generated harmful factors

Solution Approach 1:

The patent replaces continuous visual displays during waiting times with periodic haptic feedback. The control circuit activates vibration motors at specific intervals or upon user interaction to indicate device status, substituting mechanical vibration for visual signals that distract others.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
