Solution Overview

Problem

The small display size of smartwatches makes it difficult to accurately select a location on densely distributed location points, leading to accidental touches and poor user experience.

Innovation Solution

A location selection method using a rotatable component to switch between location points on a track line displayed on the smartwatch, allowing users to select locations without touching the display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If location points are densely distributed on the display to show more locations, then the quantity of displayed location points increases, but the accuracy of location selection deteriorates due to accidental touches

Engineering Contradiction:

Improvequantity of location pointsVSAvoidlocation selection accuracy

Core Design Contradiction:

Quantity of substanceVSMeasurement precision

Solution Approach 1:

The patent introduces a rotatable component as an intermediary device between the user and the location points on the display. This component allows users to select locations by rotation rather than direct touch, thereby maintaining high density of location points on the display while eliminating accidental touches and improving selection accuracy.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Area of stationary object

If the display size is kept small for wearable device design, then the device compactness is improved, but the ease of location selection deteriorates due to densely distributed location points

Engineering Contradiction:

Improvedisplay sizeVSAvoidlocation selection ease

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The rotatable component serves as a mechanical intermediary that decouples the selection operation from the display surface. Users can rotate the component to navigate through location points without needing to touch the small display area, thereby maintaining compact display size while significantly improving location selection ease.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of information

If more location points are displayed on the track line, then the completeness of location information is improved, but the difficulty of accurate location selection increases due to dense distribution

Engineering Contradiction:

Improvelocation information completenessVSAvoidlocation selection difficulty

Core Design Contradiction:

Loss of informationVSDifficulty of detecting and measuring

Solution Approach 1:

The rotatable component acts as a mediator that provides a tactile interface for navigating through the complete set of location points. Users can rotate the component to cycle through all location points in order, making it easy to identify and select the desired location without the difficulty of touching among densely distributed points on the display.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

This application relates to a location selection method, an electronic device. The electronic device may display a preset track line on a display, and display a first location point on the preset track line in a first display area of the display. When a user wants to select a second location point, the user may perform a first operation on a rotatable component, where the second location point is a location point on the preset track line, and the second location point and the first location point are different location points. The electronic device may display the second location point in the first display area in response to the first operation. The user may select a location by performing the first operation on the rotatable component, and does not need to select the location by touching a location point on the display.
