Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current methods for reinforcing the femoral neck to prevent fractures, such as pharmaceuticals and existing medical devices, are inadequate in effectively anchoring in cancellous bone and transferring load to a support structure, leading to insufficient support and potential serious side effects.

Innovation Solution

A femoral neck bone reinforcement device with a support structure that deploys from a collapsed to an expanded position, interacting with both cortical and cancellous bone regions, allowing filler material to be inserted into the cancellous bone to distribute load and provide structural support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If pharmaceuticals are used to increase bone density, then bone mass density increases slightly, but serious side effects occur

Engineering Contradiction:

Improvebone mass densityVSAvoidside effects

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent replaces pharmaceutical chemical treatment with a mechanical support structure device that provides physical reinforcement to the femoral neck, thereby achieving bone strengthening without the harmful side effects of drugs

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The support structure acts as an intermediary mechanical element between the bone and external loads, transferring and distributing forces to reduce stress on the femoral neck without requiring chemical intervention

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a balloon embodiment is used to support the upper femoral area, then general hip fracture suppression is achieved, but adequate support and reinforcement for the femoral neck is not provided

Engineering Contradiction:

Improvehip fracture suppressionVSAvoidfemoral neck support

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The support structure is specifically designed and positioned to provide localized reinforcement to the femoral neck region, concentrating structural support where it is most needed rather than providing general diffuse support

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The device is divided into multiple segments including a proximal portion, distal portion, and intermediate portion with specific geometric features that can be independently optimized for different functional requirements of femoral neck support

Inventive Principle:

Principle #1Segmentation

3Reliability

If filler material is released through bores into cancellous bone, then direct anchoring is achieved, but device complexity increases

Engineering Contradiction:

Improveanchoring effectivenessVSAvoiddevice structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The support structure incorporates bores and porous regions that allow filler material to be released and penetrate into the cancellous bone, creating mechanical interlocking and enhancing anchoring effectiveness

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The device combines the support structure material with filler material that is released through the bores, creating a composite system where the filler material bonds to both the support structure and the surrounding cancellous bone

Inventive Principle:

Principle #40Composite materials

AI summary

A device for reinforcing a femoral neck bone, the femoral neck bone including a cortical bone region and a cancellous bone region, the device including a support structure having an outer surface and including a portion having one or more bores, the one or more bores adapted to allow filler material to be released therefrom to enter directly into the cancellous bone.
