Solution Overview

Problem

Mobile computing devices face limitations in providing a hands-free, high-quality, portable display solution due to their small size and hands-dependent user interfaces, which restricts their ability to replicate the visual experience of large-format, high-resolution displays and efficient data input.

Innovation Solution

A wireless headset computer system that integrates high-resolution micro-displays and optics, enabling hands-free operation by translating voice commands and head motions into equivalent smartphone or PC commands, allowing simultaneous display output on both the headset and the primary device using a speech recognition and head tracking user interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If mobile computing devices use small display screens to maintain portability, then mobility is improved, but visual display quality and resolution are worsened

Engineering Contradiction:
Improvedevice sizeVSAvoiddisplay resolution
Core Design Contradiction:
Length of moving objectVSMeasurement precision

Solution Approach 1:

The system divides the display function into two separate devices: the mobile computing device maintains its small portable form factor, while the headset computer provides the large high-resolution display. The display output is segmented and transmitted to both devices simultaneously, allowing each to optimize for its specific function.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The headset computer acts as an intermediary device that receives display output from the mobile computing device and presents it on a larger high-resolution screen. This mediator enables the small mobile device to access large-format display capabilities without compromising its portability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If mobile devices use hands-dependent interfaces (keyboard or touch-screen), then input precision is improved, but ease of operation is worsened when hands are occupied

Engineering Contradiction:
Improveinput accuracyVSAvoidhands-free operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system replaces hands-dependent mechanical input methods (keyboard typing or touch-screen interaction) with voice-based acoustic input and head motion tracking. The headset computer captures voice commands and head movements, translating them into equivalent control commands for the mobile computing device, enabling hands-free operation.

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

Solution Approach 2:

The headset computer serves multiple functions: it provides high-resolution display output, captures voice commands, tracks head motions, and translates these inputs into control signals for the mobile device. This multi-functional device simultaneously addresses both display quality and hands-free operation needs.

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

3Volume of moving object

If mobile devices are made compact for portability, then mobility is improved, but display area is worsened

Engineering Contradiction:
Improvedevice volumeVSAvoiddisplay area
Core Design Contradiction:
Volume of moving objectVSArea of stationary object

Solution Approach 1:

The system separates the display function into a different spatial dimension by using the headset computer's display positioned in front of the user's eyes. This allows the mobile device to remain compact while the display area effectively extends to the headset's larger screen, creating a distributed display system across different spatial locations.

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