Solution Overview

Problem

Digital display devices, such as digital TVs, experience prolonged booting times due to the need to load various applications, leading to user frustration as they cannot determine if the power is on or off during the booting process, and reducing stored programs in flash memory to speed up booting is limited by increasing application complexity.

Innovation Solution

A display device that provides visual and auditory information through a screen or speaker during booting, allowing users to recognize the device's operation and enabling customizable boot screen and sound outputs using a processor, memory, and communication interfaces, such as external memory devices or wireless communication, to update and change boot data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If the amount of programs stored in flash memory is reduced to speed up booting, then booting time is shortened, but application functionality is limited

Engineering Contradiction:
Improvebooting timeVSAvoidapplication functionality
Core Design Contradiction:
Loss of timeVSAdaptability or versatility

Solution Approach 1:

The patent applies preliminary action by displaying boot screens and playing boot sounds during the booting process to provide user feedback in advance. This allows users to understand device status during the time when the screen is otherwise black, effectively addressing the booting time perception issue without reducing application functionality.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If applications associated with operations are increased to enhance functionality, then product capability is improved, but booting time becomes longer

Engineering Contradiction:
Improveproduct capabilityVSAvoidbooting time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent introduces boot screens and boot sounds as intermediary elements between the power button press and the final display output. These intermediaries provide visual and auditory feedback during the booting process, mediating the user's perception of time and reducing frustration without limiting the applications that can be loaded.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of time

If booting sequence is performed quickly to reduce waiting time, then user frustration is reduced, but information provision during booting is limited

Engineering Contradiction:
Improvebooting timeVSAvoiduser information provision
Core Design Contradiction:
Loss of timeVSLoss of information

Solution Approach 1:

The patent applies continuity of useful action by maintaining informative display and audio output throughout the booting process. Instead of having a black screen, the system continuously provides boot screens with information and plays boot sounds, ensuring that useful information is conveyed continuously during the entire booting sequence.

Inventive Principle:
Principle #20Continuity of useful action
