Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing medical implants face challenges in confirming correct anatomical alignment and placement during surgical procedures, and post-procedure complications such as neurological symptoms, pain, malfunction, inflammation, and infection are difficult to predict and prevent due to the lack of real-time monitoring and reporting capabilities.

Innovation Solution

Implantable reporting processors (IRPs) with internal sensors and wireless communication capabilities are integrated into medical devices to monitor and report the state of the implant, including kinematic measurements, pressure, and temperature, transmitting data to external recipients for analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If medical implants are made implantable (not surface-mounted), then patient comfort and medical functionality are improved, but the ability to monitor and detect implant state and complications deteriorates

Engineering Contradiction:

Improvepatient comfortVSAvoidimplant state monitoring

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent introduces an intermediary monitoring system consisting of sensors, processors, and communication devices that mediate between the implant and external observers. This system allows the implant to remain hidden inside the patient while still enabling comprehensive monitoring of its state, position, and functionality through wireless communication of sensor data to external devices.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces mechanical visual inspection methods with electronic sensing and wireless communication systems. Instead of requiring physical access or visual confirmation of implant status, the system uses electronic sensors to detect implant state and transmits this information wirelessly, eliminating the need for mechanical intervention or direct observation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If real-time monitoring capabilities are added to implants, then early detection of complications is improved, but device complexity increases

Engineering Contradiction:

Improveearly complication detectionVSAvoidmonitoring system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the monitoring system into distinct functional modules: sensors for detecting specific parameters (position, temperature, pressure), processors for analyzing sensor data, and communication devices for transmitting information. This modular segmentation allows each component to be optimized independently and simplifies the overall system architecture while maintaining comprehensive monitoring capabilities.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent designs the monitoring system with multi-functional components that can detect various types of complications using the same basic architecture. The sensors and processors are configured to monitor multiple parameters (implant position, patient vitals, infection indicators) simultaneously, reducing overall system complexity compared to having separate dedicated systems for each monitoring function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Loss of information

If sensors and communication devices are integrated into implants, then data transmission capabilities are improved, but implant size increases

Engineering Contradiction:

Improvedata transmissionVSAvoidimplant size

Core Design Contradiction:

Loss of informationVSVolume of moving object

Solution Approach 1:

The patent employs thin-film technology and flexible circuit boards to integrate sensors and communication devices into the implant structure. These thin-film components can be deposited or grown directly on the implant surface, adding minimal volume while providing comprehensive sensing and communication capabilities. The flexible nature of these films allows them to conform to the implant geometry without requiring additional space.

Inventive Principle:

Principle #30Flexible shells and thin films
