Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hearing device logistics face challenges in efficiently managing the activation and deactivation of hearing devices, leading to administrative complexities and delays in shipping, billing, warranty handling, and sales processes.
Innovation Solution
A hearing system with an operability control unit and storage unit that securely enables or disables the device based on stored data, preventing modification of this data within the system, and utilizing a signal generating unit to indicate the device's status, allowing for robust and secure control of device functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If hearing devices are delivered in a basic version with limited functionalities, then device complexity and cost are reduced, but additional functionalities require separate upgrading processes that increase administrative efforts and time
Solution Approach 1:
The hearing device is pre-configured with an integrated circuit capable of performing multiple functions, but only basic functionalities are activated initially. The device includes pre-installed software and hardware components that can be remotely activated later, eliminating the need for physical device returns or complex upgrading processes.
Solution Approach 2:
The hearing device features dynamically adjustable functionalities through remote software updates. The integrated circuit can switch between different operational modes and activate additional features based on received commands, allowing the device to evolve from a basic version to a fully functional hearing aid without physical intervention.
2Reliability
If hearing devices require online connection for upgrading, then security and control are improved, but accessibility and ease of operation are reduced
Solution Approach 1:
A remote server acts as an intermediary between the hearing device manufacturer and the user's hearing device. The server securely manages software updates and functionality activation, transmitting encrypted commands to the device's integrated circuit while maintaining centralized control over device capabilities and security protocols.
3Reliability
If hearing devices are deactivated for logistics purposes, then control and security are improved, but activation processes become complex and time-consuming
Solution Approach 1:
The activation functionality is extracted as a separate remote operation from the physical device. The hearing device contains an integrated circuit with embedded authentication mechanisms that can verify and process activation commands received remotely, separating the control logic from the physical device assembly and enabling simplified activation procedures.
