Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when switching between electronic devices, such as smartphones and wireless earphones, as they need to repeatedly pair and unpair devices, leading to performance degradation due to interference between heterogeneous networks using the same frequency bands.
Innovation Solution
An electronic device system that uses a hub device to manage connections between devices, employing different frequency bands for communication, allowing seamless data transmission and pairing without direct connection between the main device and external devices, thereby reducing interference and simplifying user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices use the same frequency band for communication, then compatibility and ease of connection are improved, but interference between heterogeneous networks increases and performance degrades
Solution Approach 1:
The patent introduces a hub device as an intermediary that mediates communication between main devices and external devices. The hub device receives data from main devices via first frequency band and transmits to external devices via second frequency band, acting as a frequency conversion intermediary that eliminates direct interference between heterogeneous networks while maintaining connection compatibility.
Solution Approach 2:
The patent changes the frequency band parameter used for communication. Instead of using the same frequency band for all device-to-device communication, the system uses different frequency bands (first frequency band for main device to hub, second frequency band for hub to external device), thereby reducing interference while maintaining adaptability through the hub's frequency conversion capability.
2Ease of operation
If devices are directly paired for data transmission, then connection speed and simplicity are improved, but the need for frequent pairing and unpairing increases when switching devices
Solution Approach 1:
The patent establishes preliminary connections between the hub device and multiple main devices, and between the hub device and multiple external devices, in advance. When a user wants to switch devices, the connection is already pre-established through the hub, eliminating the need for frequent pairing and unpairing operations. The hub maintains persistent connections that can be rapidly switched without re-pairing.
Solution Approach 2:
The hub device serves as a persistent intermediary that maintains stable connections with multiple devices simultaneously. Instead of requiring direct pairing between main devices and external devices (which would need to be repeatedly established), the hub maintains ongoing connections that mediate data transmission, thereby reducing the time loss associated with frequent pairing operations.
3Reliability
If a hub device is introduced to manage connections using different frequency bands, then interference is reduced and connection stability is improved, but device complexity increases
Solution Approach 1:
The hub device is designed with multi-functionality to justify its inclusion in the system. It performs multiple functions: receiving data from main devices via first frequency band, transmitting to external devices via second frequency band, managing connection switching, and reducing interference. This universal functionality consolidates complexity into a single device while improving overall connection stability and reliability.
