Display Apparatus User Motion Detection for Boot Time Reduction

Solution Overview

Problem

The increasing complexity of display apparatuses results in longer booting times, necessitating a solution to shorten this duration while also reducing power consumption.

Innovation Solution

A display apparatus utilizing a user detector, sensor in a remote controller, and power button to control the screen, enabling pre-power on modes and welcome screens that detect user motion, thereby reducing boot time and power usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If display apparatus functions are made complicated and diverse, then functionality and versatility are improved, but booting time increases

Engineering Contradiction:

ImprovefunctionalityVSAvoidbooting time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by detecting user presence through the camera before the user actually powers on the device. The controller activates the display and processes user input in advance, so that when the user presses the power button or makes a gesture, the system is already prepared to respond immediately, eliminating the normal booting delay.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts its operational state based on detected user presence. Rather than maintaining a static powered-off state, the system transitions to a pre-active state where selective components are activated, creating a dynamic response that adapts to user needs and reduces perceived wait time.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility
