Segmented Dental Implant Drilling Driver for Visual Field and Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dental implant placement, the limited visual field due to the drilling driver poses challenges in accurately determining the direction and depth of drilling in the alveolar bone, making it difficult to ensure proper implant placement.
Innovation Solution
A drilling driver with a specific diameter configuration, including a tip portion, a small-diameter portion, a large-diameter portion, and a diameter expanding portion, where the differences in diameters satisfy a particular ratio, and an induction portion to prevent debris from getting stuck, allowing for improved visibility and strength during the drilling process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional drilling driver with uniform diameter is used, then the structural strength is maintained, but the visual field is limited during drilling procedure
Solution Approach 1:
The drilling driver is divided into multiple sections with different diameters: a tip portion with first outer diameter, a small-diameter portion with second outer diameter smaller than the first, and a large-diameter portion with third outer diameter larger than the first. This segmentation creates a tapered profile that reduces visual obstruction while maintaining structural integrity through strategic diameter variations.
Solution Approach 2:
Different portions of the drilling driver are given different local qualities in terms of diameter. The tip portion maintains sufficient diameter for structural strength, the small-diameter portion minimizes visual obstruction in the critical viewing area, and the large-diameter portion provides overall stability. This local differentiation resolves the contradiction between strength and visibility.
2Illumination intensity
If the small-diameter portion is made thinner to improve visibility, then the visual field limitation is reduced, but the risk of driver breakage increases
Solution Approach 1:
An induction portion including an induction groove is provided in the small-diameter portion at a position biased toward the large-diameter portion. This groove creates a predetermined weak point that will break first under excessive force, serving as a safety mechanism that protects the critical tip portion and cutting edge from damage while still allowing the small-diameter portion to be thin enough for improved visibility.
Solution Approach 2:
The induction groove acts as a beforehand cushioning measure by creating a controlled failure point that absorbs excessive stress before it can propagate to the tip portion. This preliminary protective feature allows the design to use a thinner small-diameter portion for better visibility without compromising overall reliability.
3Illumination intensity
If the drilling driver is designed with optimal diameter ratios for visibility, then the visual field is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent specifies that the diameter ratio (D3-D1)/(D1-D2) should be between 1.5 and 3.0, where D1 is the first outer diameter, D2 is the second outer diameter, and D3 is the third outer diameter. This parameter specification provides clear manufacturing guidelines that balance visual field improvement with manufacturability, avoiding overly stringent precision requirements while achieving the desired tapered profile for optimal visibility.
