Hearing Device Master Selection by Operational Capability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The networking of hearing devices in a common network is unorganized, leading to data collisions and error-prone transmissions due to dynamic changes in network composition, as hearing devices join or leave, and there is a need for a reliable method to assign roles and ensure secure data exchange.
Innovation Solution
A method where one hearing device is selected as the master based on its operational capability, determined by parameters such as energy charge state, transmission quality, and error rate, to control and coordinate data exchange, ensuring optimal network operation even with dynamic changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hearing devices are connected in a common network to enable data exchange, then networking capability and data exchange functionality are improved, but network organization becomes complicated and reliability deteriorates due to dynamic changes in network composition
Solution Approach 1:
The patent implements dynamic master selection where any hearing device can become the master based on current operational conditions rather than having a fixed master. The master role can transfer between devices as network conditions change, allowing the system to adapt to dynamic network composition while maintaining reliable data exchange through consistent master-based coordination
Solution Approach 2:
The patent uses operational parameters (such as energy charge state, transmission quality, and error rate) to determine master selection. By monitoring and comparing these parameters across devices, the network dynamically identifies the most suitable master based on current conditions, resolving the contradiction between adaptability and reliability
2Device complexity
If hearing devices are selected as master or slave arbitrarily, then device complexity is reduced, but data exchange coordination becomes inefficient and productivity decreases
Solution Approach 1:
The patent determines master selection based on operational parameters such as energy charge state, transmission quality, and error rate. This parameter-based approach provides clear, objective criteria for role assignment that improves data exchange efficiency while maintaining manageable device complexity through automated comparison and selection
Solution Approach 2:
Each hearing device independently evaluates its own operational parameters and compares them with other devices to determine its role. This self-service mechanism eliminates the need for external coordination in role assignment, improving efficiency while keeping individual device complexity low
3Reliability
If the master hearing device is selected based on operational capability, then data exchange coordination and reliability are improved, but device complexity increases due to operational capability determination and comparison
Solution Approach 1:
The patent implements feedback mechanisms where hearing devices monitor their operational parameters (energy charge state, transmission quality, error rate) and use this feedback to determine master suitability. This feedback-based approach improves coordination reliability by ensuring the most capable device becomes master, while the automated nature of the feedback loop keeps implementation complexity manageable
Solution Approach 2:
The patent uses operational parameters as intermediaries to mediate master selection. Rather than direct complex evaluations, the system compares standardized parameter values (such as charge state percentages or error rate metrics) to determine role assignment, simplifying the complexity while maintaining reliable coordination
Data Source
AI summary
A method for operating a hearing device is specified. The hearing device is assigned to a user and connected to other hearing devices, which are each assigned to another user, for data exchange in a common network. The hearing device or one of the other hearing devices controls the data exchange by subscribing to the network as a master, and wherein all other hearing devices subscribe to the network as a slave. It is decided whether the hearing device subscribes to the network as a master or as a slave by determining the operational capability of the hearing device and comparing it with the operational capability of the other hearing devices and by the hearing device acting as a master if the hearing device has the highest operational capability, and otherwise as a slave.
