Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a programmer uses a specific wireless telemetry technology (e.g., RF or inductive), then it can communicate with medical devices using that same technology, but it cannot communicate with medical devices using different telemetry technologies

Engineering Contradiction:
Improvecompatibility with different medical devicesVSAvoidcomplexity of communication system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a converter device as an intermediary between the programmer and medical devices with different telemetry technologies. The converter has a first interface for communicating with the programmer using the programmer's native telemetry technology, and a second interface for communicating with the medical device using the medical device's native telemetry technology. This mediator translates and bridges the communication protocols, allowing the programmer to communicate with any medical device regardless of its specific telemetry technology without requiring the programmer itself to be complex enough to support all technologies directly.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple antenna designs are integrated into a single converter device to support both RF and inductive telemetry, then compatibility with various medical devices is improved, but the device size and complexity increase

Engineering Contradiction:
Improvesupport for multiple telemetry technologiesVSAvoidsize of converter device
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent combines multiple antenna designs (RF antenna and inductive telemetry antenna) within a single converter device housing. By merging these different antenna types and their associated circuitry into one integrated device, the system achieves support for multiple telemetry technologies (both RF and inductive) while consolidating what would otherwise be separate devices. This merging approach improves versatility without requiring multiple separate converter devices, though it does increase the volume of the single converter device.

Inventive Principle:
Principle #5Merging (Combining)
