Solution Overview

Problem

Existing implant drills face challenges in securing stability and accuracy during maxillary sinus surgery while minimizing patient discomfort and side effects by damaging the membrane and requiring artificial bone graft materials.

Innovation Solution

An implant drill design featuring a threaded cutting edge and reverse flutes that collect and push bone chips towards the drill end, lifting the maxillary sinus membrane naturally and accommodating bone chips to secure the drilling space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a conventional drill is used to drill maxillary bone and lift membrane, then drilling function is achieved, but membrane damage occurs and artificial bone graft material is required

Engineering Contradiction:

Improvemembrane damageVSAvoiddrilling function

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The drill bit is divided into functionally distinct segments: a cutting edge for drilling, a reverse flute for collecting and pushing bone chips, and a membrane lifting structure. This segmentation allows each component to perform its specific function optimally without interfering with others, thereby achieving drilling while minimizing membrane damage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Bone chips collected in the reverse flute act as an intermediary substance that naturally lifts the membrane when pushed toward the end portion. This natural lifting mechanism eliminates the need for artificial bone graft materials and reduces membrane damage compared to conventional lifting tools.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If artificial bone graft material is filled in the space generated by lifting membrane, then bone grafting is achieved, but patient discomfort and side effects increase

Engineering Contradiction:

Improvepatient discomfort and side effectsVSAvoidartificial bone graft material

Core Design Contradiction:

Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The drill bit structure enables the collected bone chips to naturally lift the membrane and fill the space without requiring external artificial bone graft materials. The system uses its own generated bone chips to achieve the bone grafting function, eliminating patient discomfort and side effects associated with artificial materials.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The bone chips that would normally be considered waste products are converted into a beneficial substance that naturally lifts the membrane and provides bone grafting material. This transforms a harmful byproduct into a useful resource, eliminating the need for artificial bone graft materials.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Manufacturing precision

If a separate cutting means is formed to penetrate alveolar bone, then drilling precision is improved, but device complexity increases

Engineering Contradiction:

Improvedrilling precisionVSAvoiddrill structure

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The cutting edge, reverse flute, and membrane lifting structures are merged into a single integrated drill bit component. This consolidation achieves drilling precision while avoiding the complexity of separate tools, as all functions are combined in one device that can be operated simultaneously.

Inventive Principle:

Principle #5Merging (Combining)
