Boot Screen and Sound Feedback for Display Device
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
2Adaptability or versatility
If applications associated with operations are increased to enhance functionality, then product capability is improved, but booting time becomes longer
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.
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
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.
