Personal Digital Module With Interchangeable Biometric Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal digital modules lack flexibility and security in device compatibility and user authentication, as they are often device-specific and lack efficient biometric authentication methods.
Innovation Solution
A personal digital module with a detachable and interchangeable design that uses a processor with executable instructions to adapt to different devices, incorporating biometric sensors for authentication and a wireless interface for data transmission, allowing secure and customizable operation across various devices such as watch bases, fire control systems, parachutist navigation systems, and helmet mounting systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a personal digital module is designed to be device-specific, then it can ensure stable operation and simplified configuration, but it lacks flexibility and cannot be used across multiple devices
Solution Approach 1:
The personal digital module is designed with a standardized connection interface that enables it to be attached to and operate with multiple different devices (watch base module, fire control system, parachutist navigation system, helmet mounting system). The module universally adapts to various devices through this common interface while maintaining device-specific functionality through automatic preference application.
2Reliability
If a personal digital module uses simple authentication, then it ensures ease of operation, but it compromises security
Solution Approach 1:
The patent replaces traditional mechanical or manual authentication methods (such as physical keys or password entry) with biometric authentication using fingerprint sensors. This substitution maintains high security through unique biometric identification while improving ease of operation since users only need to place their finger on the sensor for rapid authentication.
3Adaptability or versatility
If a personal digital module is detachable and interchangeable, then it improves adaptability and reusability, but it may compromise connection stability and reliability
Solution Approach 1:
The system is divided into separate modular components: a detachable personal digital module and a host device with a corresponding receptacle. This segmentation allows the personal digital module to be independently attached to or removed from different host devices while maintaining reliable connections through the standardized interface design with locking mechanisms.
4Reliability
If biometric sensors are integrated into the watch base module, then user authentication is enhanced, but the device complexity and manufacturing cost increase
Solution Approach 1:
The biometric authentication capability is integrated into the personal digital module which serves multiple functions: it provides authentication, displays information, and interfaces with various host devices. By consolidating these functions in a single multi-functional module rather than distributing them across multiple components, the manufacturing process is simplified while maintaining authentication security.

AI summary
A personal digital module comprises a housing and a processor with an associated computer-readable memory disposed within the housing. The memory is operably coupled to the processor and encoded with executable instructions. A human-viewable display operably is coupled to the processor and disposed within the housing. A connection interface is disposed on the housing and is configured for detachable and interchangeable attachment of first device and a second device. The processor is configured, upon execution of the executable instructions, to perform a first function associated with the first device when the personal digital module is attached to the first device and to perform a second function associated with the second device when the personal digital module is attached to the second device.
