Digital Dental Impression Stroke Completion Trigger Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental procedure planning systems face challenges in efficiently processing and adjusting digital dental impressions, particularly with touch-based interfaces, where real-time computation of 3D shapes is resource-intensive and less precise compared to traditional input devices, leading to delays and reduced user interaction.
Innovation Solution
A computer-implemented method using trigger logic to detect stroke completion in digital dental impression systems, allowing for faster processing by executing algorithms only when necessary, enabling faster frame rates and reducing processing requirements by automatically altering shaded and unshaded regions upon stroke completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If real-time computation of 3D shapes is performed continuously, then the system provides responsive user interaction, but the processing requirements become excessively resource-intensive
Solution Approach 1:
The system performs computation only at specific trigger events (stroke completion) rather than continuously. The trigger logic detects when a user has finished drawing a stroke and initiates processing at that discrete moment, creating a periodic rather than continuous computation pattern that reduces overall resource consumption while maintaining perceived responsiveness.
Solution Approach 2:
The system uses the user's own input actions as triggers for processing. When the user completes a stroke, this action automatically triggers the computation without requiring additional system resources for continuous monitoring. The user's interaction itself serves as the trigger mechanism.
2Ease of operation
If touch-based interfaces are used for adjusting digital dental impressions, then portability and convenience are improved, but precision and control are reduced compared to traditional input devices
Solution Approach 1:
The system allows users to perform preliminary actions (drawing strokes) without immediate processing. Users can sketch out their intended adjustments freely, and the system processes these actions only when the user indicates completion. This preliminary phase allows for easy, portable interaction while the subsequent processing ensures precision.
Solution Approach 2:
The trigger logic acts as an intermediary between the user's touch input and the processing system. It captures the user's intent to complete an action and translates it into a precise processing trigger, bridging the gap between the imprecise nature of touch input and the precision required for dental adjustments.
3Loss of time
If algorithms are executed continuously to maintain real-time visualization, then user interaction responsiveness is improved, but processing time is wasted on unnecessary computations
Solution Approach 1:
The system executes algorithms periodically at trigger events rather than continuously. The trigger logic identifies specific moments (stroke completion) when processing is actually needed, eliminating wasted computation time while maintaining responsiveness at critical interaction points.
Solution Approach 2:
The system extracts and isolates the essential trigger condition (stroke completion) from the continuous stream of user input. By separating the trigger detection from continuous processing, the system eliminates unnecessary computations while preserving the essential responsiveness needed for user interaction.
