Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The establishment of Bluetooth connections between devices is complex and costly due to the need for Near Field Communication (NFC) chips, which increases hardware costs and complicates the connection process, affecting user experience and efficiency.
Innovation Solution
A method where a Bluetooth connection is automatically established between devices when the signal strength reaches a preset threshold, eliminating the need for NFC chips and simplifying the connection process by allowing devices to connect seamlessly as they approach each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If NFC chips are added to enable automatic Bluetooth connection, then connection intelligence is improved, but hardware cost increases
Solution Approach 1:
The patent extracts and removes the NFC chip component from the connection establishment system, replacing it with a solution that uses only Bluetooth signal strength detection. This eliminates the need for additional hardware while maintaining automatic connection capability, directly resolving the contradiction between connection intelligence and hardware cost.
Solution Approach 2:
The patent makes the Bluetooth module perform multiple functions: not only traditional Bluetooth communication but also proximity detection and automatic connection triggering. By using the existing Bluetooth signal strength for connection decision-making, the system achieves NFC-like automatic connection functionality without requiring separate NFC hardware, thus reducing cost while maintaining intelligence.
2Reliability
If manual connection confirmation is required, then connection reliability is improved, but connection time increases
Solution Approach 1:
The patent performs preliminary actions by continuously monitoring Bluetooth signal strength in advance and preparing connection parameters before actual connection is needed. When signal strength reaches the threshold, the connection is automatically initiated without requiring user intervention, thus reducing connection time while maintaining reliability through pre-validated connection parameters.
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously monitors Bluetooth signal strength and uses this information to automatically trigger connection when conditions are favorable. This closed-loop approach ensures reliable connections are made at the optimal moment without manual confirmation, balancing reliability and speed.
3Reliability
If additional operations are required for connection, then connection reliability is improved, but ease of operation worsens
Solution Approach 1:
The patent enables the system to serve itself by automatically monitoring Bluetooth signal strength and initiating connections without user intervention. The device autonomously determines when connection conditions are met and executes the connection process, eliminating the need for manual operations while ensuring reliable connections through algorithmic decision-making based on signal quality.

AI summary
A communication method is provided, which includes that: in response to detecting a first signal of a second device, a first device determines a signal strength between the first device and the second device; and in response to that the signal strength reaches a preset signal strength threshold, the first device establishes a connection with the second device. Another communication method is also provided, which includes that: a second device broadcasts a first signal, and the second device establishes a connection with a first device in response to a connection request triggered by that a signal strength between the first device and the second device reaches a preset signal strength threshold.
