Wireless Display Local OS Fallback for Connection Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless detachable display apparatuses are limited in functionality as they cannot be used when the wireless connection with the host apparatus is disconnected or weak, restricting their portability and usability beyond a certain range.
Innovation Solution
A display apparatus equipped with a communication interface to detect the wireless connection state with the host apparatus and a controller to generate and display local image data when the connection is weak or lost, allowing the user to choose between displaying received data or local data, and enabling connectivity with an internet network for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication method is used to connect host apparatus and display apparatus, then portability and ease of operation are improved, but reliability deteriorates when connection is lost or weak
Solution Approach 1:
The display apparatus is equipped with an operating system and local application programs that enable it to function independently without continuous reliance on the host apparatus. When wireless connection is lost, the display apparatus can still execute local applications and display content, effectively serving itself and maintaining functionality autonomously.
Solution Approach 2:
The display apparatus预先 stores local application programs and operates in a standby state, ready to take over functionality when wireless connection fails. This preparatory measure ensures that when connection is lost, the system can immediately switch to local operation without complete functional breakdown, cushioning the impact of connection failure.
2Ease of operation
If wireless communication method is used, then ease of operation is improved, but reliability deteriorates when display apparatus moves outside wireless range
Solution Approach 1:
By equipping the display apparatus with its own operating system and local applications, it can function as an independent device when moved outside wireless range. The apparatus serves itself by executing local programs and displaying content without needing continuous communication with the host apparatus, maintaining usability regardless of position.
Solution Approach 2:
The display apparatus is designed to perform multiple functions: it can display content from the host apparatus when connected, and independently execute local applications when disconnected. This multi-functionality ensures the device remains versatile and useful in both connected and disconnected states, across different locations.
3Adaptability or versatility
If display apparatus operates independently with operating system, then adaptability is improved, but device complexity increases
Solution Approach 1:
Instead of implementing a full-featured operating system with all possible functions, the display apparatus runs a simplified version that provides essential independent operation capabilities. This partial implementation achieves the necessary adaptability for basic standalone functionality while avoiding the excessive complexity of a complete OS, balancing capability and complexity.

AI summary
A display apparatus includes a communication interface configured to wirelessly receive first image data from a host apparatus, a user interface configured to display the received first image data, and a controller configured to control the user interface to generate second image data by operations of an operating system of the display apparatus, and display at least one of the generated second image data and the received first image data.
