Innovation Solution

A secure medical device system utilizing a computer processing device with multiple wireless access points, a locally-served web site, and a cloud-based portal for secure communication and data management, allowing for concurrent operation of short-range and long-range wireless connections, and enabling secure control of diagnostic test units using mobile computing devices with web browser applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If new equipment is provided to improve security for data transmission and storage, then security is improved, but cost increases

Engineering Contradiction:

ImprovesecurityVSAvoidcost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The system uses standard wireless access points and web browser technology that can be implemented on existing devices, making the security solution universally applicable without requiring specialized expensive hardware. The locally-served web site interface works with any mobile computing device that has a web browser, eliminating the need for costly device-specific solutions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a computer processing device as an intermediary between mobile devices and diagnostic test units. This intermediary provides the secure web-based interface and data management functions, allowing existing mobile devices to access secure communication capabilities without requiring the mobile devices themselves to be expensive specialized equipment.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If custom hardware is used to meet security requirements, then security is improved, but compatibility with other devices deteriorates

Engineering Contradiction:

ImprovesecurityVSAvoidcompatibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent replaces custom hardware interfaces with a software-based web browser interface. Instead of requiring specialized hardware connectors or proprietary communication protocols, the system uses standard wireless communication and web protocols that are universally supported by different device types, thereby maintaining compatibility while ensuring security through software encryption and authentication mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The locally-served web site interface is designed to be universally accessible by any mobile computing device with a web browser, including smartphones, tablets, and laptops. This universal interface approach allows the system to maintain security without sacrificing compatibility across different device platforms and manufacturers.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple wireless access points are used to enable concurrent connections, then functionality is improved, but device complexity increases

Engineering Contradiction:

Improveconcurrent connection capabilityVSAvoidwireless access point configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments wireless communication into distinct functional components: a first wireless access point for local mobile device connections and a second wireless access point for remote network communication. This segmentation allows each access point to be independently configured and managed, simplifying the overall system complexity while enabling concurrent connections to both local and remote networks simultaneously.

Inventive Principle:

Principle #1Segmentation

AI summary

A secure medical device system (30; 30′) includes a computer processing device (42) that includes a processor, memory in communication with the processor, an interface enabling communication between the processor and a diagnostic test unit (40; 40′), a first wireless access point (48A), computer-readable instructions stored in the memory and executable by the processor providing a locally-served web site (46) that is browser accessible over the first wireless access point, and a second wireless access point (48B) operable concurrently with and independent from the first wireless access point. The locally-served web site is adapted to receive control instructions over the first wireless access point and to generate command signals transmittable over the interface to the diagnostic test unit, and the second wireless access point enables communication between the processor and an external network (36).
