Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wearable devices often present private data, such as a correspondent's identity, in a manner that makes it easily viewable by nearby observers, compromising user privacy.

Innovation Solution

A wearable device design featuring a public display on the dorsal side and a private display on the ventral side, with the private display being less visible to observers, and only viewable by the wearer when in a specific orientation, using a combination of hardware and software to manage data presentation based on privacy thresholds and user authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If private data is displayed on a wearable device, then the wearer can easily access and view the data, but nearby observers can also see the data, compromising user privacy

Engineering Contradiction:

Improveaccess to private dataVSAvoidprivacy exposure to observers

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The display is segmented into two distinct regions: a public display area visible to observers and a private display area that is not easily visible to others. This segmentation allows the device to simultaneously provide easy access to private data for the wearer while preventing privacy exposure to nearby observers.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the display are assigned different visibility qualities. The public display area is positioned and designed to be easily visible to observers, while the private display area is positioned and designed to be easily visible only to the wearer, creating local quality differences in visibility.

Inventive Principle:

Principle #3Local quality

2Device complexity

If a single display is used for both public and private data, then device complexity is reduced, but privacy protection is compromised

Engineering Contradiction:

Improvedisplay structureVSAvoidprivacy exposure

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

Instead of using a single undivided display, the display is segmented into distinct public and private display areas. This segmentation enables privacy protection by ensuring that private data displayed in the private area cannot be easily seen by observers, while maintaining relatively simple device architecture.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If private data is displayed in a location visible to observers, then ease of viewing for the wearer is improved, but privacy is compromised

Engineering Contradiction:

Improveviewing of private dataVSAvoidprivacy information leakage

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The private display area is positioned and oriented with specific local quality characteristics that make it easily viewable by the wearer (through body orientation or direct line of sight) while simultaneously making it invisible or difficult to view by nearby observers, thus preventing privacy information leakage.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The display solution moves from a two-dimensional flat display to a three-dimensional spatial arrangement where the private display area is positioned in a location and orientation that is easily accessible to the wearer's line of sight but obscured from observers, utilizing the third dimension (depth/space) to resolve the contradiction.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

For displaying data on a wearable device, a public display wearable on a wrist presents public data. A private display wearable on the wrist presents private data. The private data may include a correspondent identity.
