Solution Overview

Problem

Hearing device manufacturers face the challenge of ensuring that discounted secondary hearing devices are only used by the same user who purchased the primary device, preventing them from being sold at full price to new customers.

Innovation Solution

Implementing a personal token system that enables fitting and operation of hearing devices only if the token is present, ensuring that secondary devices are associated with the primary user and cannot be used or sold as primary devices without the token.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If discounted secondary hearing devices are provided to users, then user satisfaction and brand loyalty are improved, but the risk of unauthorized sale at full price to new customers increases

Engineering Contradiction:

Improveuser satisfactionVSAvoidauthorization control

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

A personal token is introduced as an intermediary between the user and the hearing device. The token contains authorization information that must be presented to the device for it to operate. This mediator enables the device to verify whether the user is authorized to use it, thereby preventing unauthorized sales while allowing legitimate discounted device usage.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Authorization information is embedded in the personal token before the user receives the hearing device. This preliminary action of pre-configuring the token with authorization data allows the device to later verify the user's legitimacy without requiring real-time external verification, thus preventing unauthorized use from the outset.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If a personal token system is implemented to prevent unauthorized use, then authorization control is improved, but device complexity increases

Engineering Contradiction:

Improveauthorization controlVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The authorization verification function is extracted from the hearing device itself and placed in the personal token. The token contains the authorization information and can be independently verified by the device. This extraction reduces the complexity burden on the main hearing device while maintaining strong authorization control through the separate token component.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

The present invention pertains to a method for fitting a hearing device to needs and preferences of a user and/or for operating the hearing device. The method comprises determining whether a personal token of the user is located in proximity of the hearing device (10). The method further comprises enabling fitting of the hearing device to the needs and preferences of the user and/or enabling operating of the hearing device only if the personal token has been determined to be located in proximity of the hearing device, otherwise disabling fitting and/or operating of the hearing device (20). Furthermore, a corresponding fitting system and a set of associated hearing devices as well as a use of the latter are provided.
