Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Bluetooth protocol defaults to remembering the last connected apparatus, leading to automatic reconnection issues, security vulnerabilities, and unnecessary manual disconnection steps, especially when multiple devices are involved.
Innovation Solution
A communication method and system that allows electronic apparatuses to obtain and manage configuration information to determine the uniqueness of connected devices, enabling selective saving or deletion of description information to control automatic reconnection based on user preferences and security settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the Bluetooth protocol remembers the last connected apparatus by default, then automatic reconnection is enabled, but security vulnerabilities and unnecessary manual disconnection steps occur
Solution Approach 1:
The patent applies dynamics by making the connection memory behavior adjustable rather than fixed. The electronic apparatus dynamically changes its connection behavior based on user-selected modes: in first mode, it remembers and automatically reconnects to the last connected apparatus; in second mode, it does not remember and requires manual reconnection. This dynamic adaptability resolves the contradiction between automation and security by allowing users to switch between automatic reconnection (high automation) and manual reconnection (high security) based on their needs.
2Extent of automation
If the Bluetooth protocol remembers the last connected apparatus by default, then automatic reconnection is enabled, but unnecessary manual disconnection steps occur
Solution Approach 1:
The patent makes the connection memory behavior dynamic through user-selected modes. In the first mode, the apparatus automatically remembers and reconnects to the last connected apparatus, eliminating manual disconnection steps. In the second mode, it does not remember connections, requiring manual reconnection but also eliminating the need for manual disconnection. This dynamic approach resolves the contradiction by allowing users to choose the behavior that best fits their operational needs.
3Adaptability or versatility
If configuration information is obtained and description information is selectively saved or deleted, then user control over connections is enhanced, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the connection management functionality into distinct operational modes (first mode for remembering connections, second mode for not remembering). This segmentation simplifies the overall system logic by creating clear, discrete states rather than requiring complex continuous decision-making. Each mode has straightforward save/delete behavior, reducing the complexity burden while maintaining high adaptability through mode switching.
4Adaptability or versatility
If the Bluetooth protocol is modified to support selective remembering, then connection flexibility is improved, but protocol compatibility issues may arise
Solution Approach 1:
The patent applies universality by implementing the selective remembering feature within the electronic apparatus itself, making it compatible with existing Bluetooth protocols without requiring protocol modifications. The apparatus universally supports both connection modes (remembering and not remembering) while working with standard Bluetooth protocols, thus maintaining protocol compatibility while achieving connection flexibility through device-level functionality rather than protocol-level changes.

AI summary
A communication method applied to a first electronic apparatus includes, after establishing a communication connection with a second electronic apparatus, obtaining configuration information from the second electronic apparatus, monitoring a communication state between the first electronic apparatus and the second electronic apparatus, and saving or deleting second description information corresponding to the second electronic apparatus based on the configuration information after the first electronic apparatus is disconnected from the second electronic apparatus. The second description information includes information that represents uniqueness of the second electronic apparatus.
