Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital TV systems require complex procedures for connecting a display device to an external speaker via Bluetooth, which is inconvenient for users.
Innovation Solution
A display device and external speaker system that allows connection through a simplified process by using a button on the external speaker to transmit an IR keycode, generating a random key set, and establishing a Bluetooth connection when the keycodes match.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional Bluetooth connection procedure is used between display device and external speaker, then the connection can be established, but the connection procedure becomes complex and inconvenient for users
Solution Approach 1:
The patent introduces an infrared (IR) code as an intermediary signal to facilitate the Bluetooth connection between display device and external speaker. The external speaker transmits a unique IR code to the display device, which acts as a mediator to trigger the Bluetooth pairing process automatically, eliminating the need for users to manually navigate through complex Bluetooth settings on both devices.
Solution Approach 2:
The external speaker performs preliminary action by generating and transmitting its unique IR code to the display device before the actual Bluetooth connection is established. This preliminary transmission of identification information allows the display device to pre-configure the connection parameters, so that when the user presses the button on the external speaker, the Bluetooth connection is quickly established without requiring complex user input.
2Productivity
If manual Bluetooth pairing is required between multiple display devices and external speaker, then connection can be made, but the connection process becomes time-consuming and inconvenient
Solution Approach 1:
The IR code serves as an intermediary that carries the unique identification of the external speaker. When the display device receives this IR code, it automatically identifies the target speaker and initiates the Bluetooth connection process, eliminating the need for manual device selection and pairing steps that would be required when connecting multiple display devices to multiple speakers.
Solution Approach 2:
The system enables self-service connection where the external speaker automatically transmits its identification code and the display device automatically processes the connection request. This self-service mechanism allows multiple display devices to quickly connect to multiple external speakers without requiring manual intervention for each pairing, significantly reducing connection time and improving productivity.
