Multimedia Player Connection via Main Device Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection methods between a control terminal and a multimedia playing system are cumbersome and inconvenient for users, particularly due to the need for manual selection of Bluetooth devices and potential confusion among numerous device names, leading to incorrect connections and user frustration.
Innovation Solution
A connection method where the control terminal transmits selection information based on a playing device information list to the main device, which determines and acquires the necessary wireless connection information to establish a wireless communication connection automatically, eliminating the need for users to know specific connection details such as device names and passwords.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the Bluetooth unit is kept in normally open state to avoid frequent manual switching, then the ease of operation is improved, but the device complexity increases due to numerous Bluetooth unit names displayed causing user confusion
Solution Approach 1:
The patent segments the Bluetooth connection interface into two distinct modes: discovery mode (displaying all available devices) and connection mode (displaying only connected devices). This segmentation allows the system to present simplified information based on the current operational state, reducing interface complexity while maintaining ease of operation.
Solution Approach 2:
The patent implements dynamic interface adaptation where the Bluetooth unit list dynamically changes its content based on the connection state. When a device is connected, the interface automatically transitions to showing only relevant connected devices, making the interface behavior adaptive and responsive to user needs without requiring manual reconfiguration.
2Measurement precision
If the user manually selects Bluetooth devices from a list, then the connection accuracy is improved, but the loss of time increases due to the need to search and select among numerous device names
Solution Approach 1:
The patent performs preliminary action by automatically acquiring and storing connection information (device names, addresses, passwords) when devices are first connected. This pre-stored information enables rapid reconnection without requiring users to search or verify connection details again, significantly reducing connection time while maintaining accuracy through automated information retrieval.
Solution Approach 2:
The system performs self-service by automatically managing the Bluetooth connection process. When a user initiates a connection, the system automatically retrieves stored connection information, verifies credentials, and establishes the connection without requiring manual intervention for each step, thereby reducing both time loss and operational complexity.
3Adaptability or versatility
If the system displays all Bluetooth unit names including nearby devices, then the adaptability is improved, but the ease of operation deteriorates due to user confusion and wrong choices
Solution Approach 1:
The patent applies local quality by customizing the interface content based on the user's current context and needs. Instead of uniformly displaying all possible Bluetooth devices, the system adapts the display to show only relevant devices (e.g., previously connected devices or devices in the same network), making the interface more user-friendly while maintaining the ability to connect to various devices.
Solution Approach 2:
The patent introduces an intermediary layer (the adaptive interface) between the user and the raw list of all Bluetooth devices. This intermediary filters and organizes the device list based on connection history, network membership, and user preferences, presenting a simplified and more intuitive interface that reduces user confusion while preserving access to all compatible devices.

AI summary
The present disclosure provides a connection method for a multimedia playing device, a main device, a control terminal, and a system. The connection method includes: receiving selection information based on a playing device information list from a control terminal, determining a playing device to be connected in accordance with the selection information, and acquiring wireless connection information of the playing device to be connected by a main device; and transmitting the wireless connection information acquired to the control terminal by the main device, whereby the control terminal will establish a wireless communication connection with the playing device to be connected in accordance with the wireless connection information. Through the technical schemes described above, it is not necessary for the user to know connection information (such as the name of a wireless unit and password) required for establishing a wireless communication connection of the playing device to be connected. Automatic connection between the control terminal and the playing device to be connected can be achieved via selecting the name of the playing device to be connected from the playing device information list of the control terminal. It can be seen that the process can be implemented easily and quickly as well as effectively enhance the user experience.
