Solution Overview

Problem

The reduction in size of portable electronic devices has led to smaller input mechanisms and displays, making them difficult for users with poor vision or in dark environments to navigate and use effectively, necessitating improved user interface feedback solutions.

Innovation Solution

The provision of tactile feedback in electronic devices through vibration, temperature changes, or electrical discharges, which can be tailored based on device states, user inputs, or environmental conditions, to enhance usability and accessibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If the size of portable electronic devices is reduced, then portability is improved, but the size of input mechanisms and displays decreases making them difficult to navigate

Engineering Contradiction:
Improvedevice sizeVSAvoidusability
Core Design Contradiction:
Weight of moving objectVSEase of operation

Solution Approach 1:

The patent applies vibration feedback through a vibration motor that generates tactile sensations when activated. This mechanical vibration provides users with physical feedback about device states, menu selections, and navigation options without requiring visual input, thereby compensating for the reduced display size in portable devices.

Inventive Principle:
Principle #18Mechanical vibration

Solution Approach 2:

The system implements a feedback mechanism where the processor monitors user interactions and device states, then activates the vibration motor to provide tactile feedback. This closed-loop feedback system helps users understand the current state of the device and navigate interfaces more effectively despite smaller display and input mechanisms.

Inventive Principle:
Principle #23Feedback

2Volume of moving object

If the size of displays is reduced, then device portability is improved, but visibility and readability in dark environments deteriorates

Engineering Contradiction:
Improvedisplay sizeVSAvoidvisibility
Core Design Contradiction:
Volume of moving objectVSIllumination intensity

Solution Approach 1:

The patent replaces visual feedback mechanisms with tactile feedback mechanisms. Instead of relying on display illumination that is difficult to see in dark environments, the system uses vibration motors to provide feedback through touch, substituting the visual channel with a tactile channel that remains effective regardless of lighting conditions.

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

Solution Approach 2:

While not directly related to illumination, this principle illustrates the patent's approach to providing feedback through different sensory modalities. The vibration motor provides feedback that is independent of visual perception, effectively replacing the need for illuminated displays in dark environments.

Inventive Principle:
Principle #32Color changes

3Device complexity

If the size of input mechanisms is reduced, then device compactness is improved, but ease of interaction and selection deteriorates

Engineering Contradiction:
Improveinput mechanism sizeVSAvoidinteraction
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The vibration motor provides tactile feedback that helps users identify and select options on the reduced input mechanism. By activating vibration at specific moments during interaction, the system compensates for the smaller size of buttons and controls, making them easier to locate and operate without visual assistance.

Inventive Principle:
Principle #18Mechanical vibration

Solution Approach 2:

The system implements feedback that connects the reduced input mechanism to the user's tactile sense. The processor monitors input actions and triggers vibration feedback that confirms selections and guides navigation, making the smaller input mechanism easier to use by providing immediate tactile confirmation of user actions.

Inventive Principle:
Principle #23Feedback
