Apparatus Pairing via Distance Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for networking apparatuses in operation environments lack simplicity and safety, often leading to unintended connections with neighboring environments due to the limitations of Bluetooth and other short-range communication technologies.
Innovation Solution
The method employs communication devices with short and long ranges to establish secure connections within an operation environment, using distance and direction measurements to limit networking to specific thresholds, ensuring only apparatuses within a defined proximity can exchange data and form a subnetwork, while maintaining compatibility with standards like SDC for secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Bluetooth technology is used for apparatus networking in operation environments, then apparatuses can be connected and exchange data, but unintended connections with neighboring environments may occur due to insufficient connection control
Solution Approach 1:
The patent applies local quality by making the communication connection establishment location-dependent. The system determines the location of the second apparatus relative to the first apparatus and only establishes connections when the second apparatus is in an appropriate location (e.g., same operation environment). This resolves the contradiction by enabling connectivity within the local environment while preventing unintended connections in neighboring environments.
Solution Approach 2:
The patent implements feedback by continuously monitoring the location of apparatuses and using this information to control connection establishment. The system receives location information, evaluates whether the second apparatus is in an appropriate location, and based on this feedback, either permits or blocks the formation of communication connections. This feedback mechanism ensures reliable and safe networking.
2Reliability
If short-range communication devices are used to limit networking range, then connections can be limited to operation environment, but additional location determination requirements increase system complexity
Solution Approach 1:
The patent applies universality by making the first apparatus perform multiple functions: it serves as both a communication device for data exchange and as a location determination device for establishing networking boundaries. By integrating these functions into a single apparatus, the system achieves reliable boundary control without significantly increasing overall system complexity.
Solution Approach 2:
The patent uses an intermediary approach by introducing location information as a mediating factor between the communication devices. Rather than modifying the communication protocol itself, the system uses location information from separate determination devices to control connection establishment. This intermediary mechanism adds boundary control capability while keeping the communication subsystem relatively simple.
3Reliability
If distance determination is used to control connection establishment, then unintended connections can be prevented, but the networking process becomes more complex with additional measurement requirements
Solution Approach 1:
The patent applies self-service by enabling apparatuses to automatically determine their own locations and use this information to control their own connection establishment. The first apparatus determines the location of the second apparatus and autonomously decides whether to establish a connection based on whether the location is appropriate. This automation reduces the need for manual intervention and maintains ease of operation while improving control accuracy.
Solution Approach 2:
The patent implements preliminary action by determining the location of apparatuses before establishing communication connections. The system performs location determination as a preliminary step, evaluates whether the location is appropriate, and only then proceeds with connection establishment if conditions are met. This preliminary check ensures reliable connection control while streamlining the overall process by preventing failed connection attempts.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for automatic or semi-automatic pairing and decoupling of apparatuses based on distance, preventing unintended connections with neighboring environments, ensuring secure and efficient data exchange within the operation environment.
Implementation Method 1
For a distance determination the field strength of a wirelessly transmitted signal at the receiving apparatus can be used, for example
Data Source
AI summary
A system allowing automatic pairing of different apparatuses within different operation environments. The pairing is carried out based on signal strength or indoor navigation (e.g. Bluetooth). It is detected whether a communication partner, i.e. another apparatus, is present in a distance within a predefined radius (S1) from any other apparatus or from a central apparatus. During the detection the pairing is initiated automatically by (UUID) or certificate exchange without additional interaction by the user or with simple confirmation by the user.
