Solution Overview

Problem

Current electronic devices face challenges in providing an efficient and user-friendly method for text input on interactive displays, particularly in wearable devices where the input and display screens are integrated, leading to difficulties in inputting text while maintaining visibility of content.

Innovation Solution

A wearable electronic device design featuring a circular display with a touch-sensitive layer and an outer rotatable ring that allows for text input through gestures and character selection, incorporating sensors and haptic feedback for intuitive interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the input screen and display screen are integrated on the same surface, then the device can display content while receiving input simultaneously, but the user cannot view content clearly while inputting text

Engineering Contradiction:

Improveintegrated display and input functionalityVSAvoidvisibility during text input

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The display surface is segmented into distinct functional zones: a first region for displaying content and a second region for text input. This spatial segmentation allows the content display and input operations to occur simultaneously without interfering with each other, resolving the contradiction between integrated functionality and visibility during input.

Inventive Principle:

Principle #1Segmentation

2Productivity

If a separate physical keyboard is added for text input, then text input efficiency is improved, but the device size and complexity increase

Engineering Contradiction:

Improvetext input efficiencyVSAvoiddevice structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The input functionality is merged with the display surface by making the display screen itself touch-sensitive. This integration eliminates the need for separate physical keyboards while maintaining text input capability, thus improving productivity without increasing device complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The display screen serves multiple functions: it displays content in the first region and receives text input in the second region. This multi-functionality allows the same surface to fulfill both display and input roles, avoiding the need for additional components and reducing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If the display screen is made touch-sensitive for direct input, then ease of input is improved, but precision of text input decreases

Engineering Contradiction:

Improvedirect input capabilityVSAvoidtext input precision

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

A virtual keyboard is introduced as an intermediary layer on the touch-sensitive display. This virtual keyboard provides precise input targets while maintaining the ease of direct touch interaction, resolving the contradiction between ease of operation and input precision.

Inventive Principle:

Principle #24Intermediary (Mediator)
