Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a lack of effective solutions for recording and accessing information on implantable devices or prostheses, such as graft stents, which are often used in vascular and cardiovascular interventions, making it difficult to track their location and store data within the body.

Innovation Solution

The use of implantable magnetizable fabric coupled to a graft segment of a prosthesis, allowing information to be written and detected using a magnetic detection device after the prosthesis is delivered into the body, enabling easy access and storage of data without the need for continuous electrical power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If implantable devices or prostheses are used in the body for extended periods, then they provide necessary medical support, but there is no effective solution to record and access information on these devices

Engineering Contradiction:

Improveinformation recording capabilityVSAvoiddevice structure

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines the data storage function with the implantable prosthesis structure by integrating magnetizable fabric into the graft stent. This merging allows the prosthesis to simultaneously provide its primary medical function and store information about patient and procedural data without requiring separate storage devices

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent uses magnetic patterns as a copy of information that can be written on and read from the magnetizable fabric. Instead of storing complex digital data directly, the system creates magnetic representations of information that can be detected and interpreted, simplifying the storage and retrieval process

Inventive Principle:

Principle #26Copying

2Loss of information

If traditional data storage methods are used in implantable devices, then information can be stored, but continuous electrical power is required

Engineering Contradiction:

Improvedata storageVSAvoidcontinuous power consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

The patent employs passive magnetic storage that functions similarly to disposable or single-use storage media. Once information is written to the magnetizable fabric, it is retained without requiring ongoing energy input, analogous to how written information on paper persists without power

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent replaces electronic/digital storage systems that require continuous power with a magnetic field-based storage system. By substituting electronic circuits with magnetizable material, the system eliminates the need for continuous electrical power while maintaining data storage capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Loss of information

If information is stored on implantable devices, then tracking and data management are improved, but detection and access of the information becomes more difficult

Engineering Contradiction:

Improveinformation accessibilityVSAvoidinformation detection

Core Design Contradiction:

Loss of informationVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces a magnetic detection device as an intermediary between the stored magnetic patterns and the information they represent. This mediator translates the magnetic field patterns on the fabric into readable information, making the detection process straightforward despite the complexity of magnetic field measurement

Inventive Principle:

Principle #24Intermediary (Mediator)
