Solution Overview

Problem

Wearable devices such as smart watches and activity trackers face excessive battery consumption due to unnecessary activation of displays, which can be wasteful and reduce device functionality.

Innovation Solution

An apparatus and method that utilize a processor and memory to receive activity type data and sensor information, detect specific changes in measurement values, and activate or deactivate the display based on pre-learned rules and user-specific settings, optimizing display usage according to the user's activity, such as sport, daily use, or sleeping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display is kept activated to ensure user can view information, then user convenience is improved, but battery consumption increases

Engineering Contradiction:
Improveuser convenienceVSAvoidbattery consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The display activation state is made dynamic rather than static. The system continuously monitors sensor data and automatically transitions the display between activated and deactivated states based on detected user actions, optimizing the balance between user convenience and energy consumption.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses sensor feedback (acceleration, gyroscope, ambient light) to detect user interactions and automatically control display activation. This closed-loop feedback mechanism ensures the display is activated only when users actually need it, reducing unnecessary energy consumption while maintaining convenience.

Inventive Principle:
Principle #23Feedback

2Loss of information

If the display is activated continuously to provide information access, then information accessibility is improved, but energy waste increases

Engineering Contradiction:
Improveinformation accessibilityVSAvoidenergy waste
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The system performs preliminary detection of user actions through sensors before activating the display. By detecting user interactions in advance through acceleration and gyroscope data, the system prepares for display activation only when necessary, preventing energy waste from unnecessary activations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The display control system serves itself by automatically detecting user needs through sensor data and making activation decisions without manual intervention. This self-service mechanism ensures information accessibility is maintained while eliminating energy waste from unnecessary display operation.

Inventive Principle:
Principle #25Self-service

3Device complexity

If the display activation is based on general rules, then system simplicity is maintained, but user-specific needs are not met

Engineering Contradiction:
Improvesystem simplicityVSAvoiduser-specific adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The display activation system is segmented into multiple independent components: sensor data acquisition, action detection algorithms, ambient light sensing, and display control. This modular segmentation allows the system to remain simple while incorporating multiple sensing modalities and customizable activation rules for different user scenarios.

Inventive Principle:
Principle #1Segmentation
