Wireless Display Controller On-Demand Login Logout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with wireless interfaces for switching devices often experience errors in connection due to unspecific login and logout procedures, and the wireless interface remains constantly activated, which is undesirable in certain environments.
Innovation Solution
A display device with a wireless interface that activates only upon a specific event, such as a critical operating state, and automatically deactivates after data transmission, featuring a controller that manages a multicolor display element and communication over the wireless interface, including a precise login and logout process to prevent errors and conserve energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wireless interface is constantly activated to enable communication, then data transmission capability is improved, but energy consumption increases
Solution Approach 1:
The wireless interface is activated periodically only when specific events occur (predetermined events such as critical operating states or button actuations) rather than remaining constantly active. The controller activates the wireless interface upon detecting such events, transmits data, and then deactivates it after completion, creating a periodic on-demand operation pattern that reduces energy consumption while maintaining data transmission capability when needed
2Ease of operation
If a simple wireless connection is implemented, then ease of operation is improved, but connection errors increase due to ambiguous login/logout procedures
Solution Approach 1:
The controller is configured to automatically initiate a login process before data transmission and to automatically initiate a logout process after data transmission completion. These preliminary and subsequent actions are performed automatically by the controller based on event detection and transmission status, eliminating the need for manual connection management while ensuring proper connection establishment and termination, thereby preventing connection errors
3Reliability
If the wireless interface remains active for extended periods, then communication reliability is improved, but device complexity increases due to continuous operation requirements
Solution Approach 1:
The controller automatically manages the wireless interface lifecycle by detecting predetermined events, activating the interface when needed, initiating login processes, transmitting data, detecting transmission completion, and initiating logout processes. This self-service automation eliminates the need for complex manual operation management while ensuring the wireless interface is active only when necessary for communication, thereby maintaining reliability without increasing operational complexity
