Multi-Camera Dental Handpiece for Blind Spot Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental handpieces with mounted camera modules often experience a blind spot for the drilled face due to the positional relationship of the drilling tool, light entry, and teeth, making it impossible to observe the drilled area effectively.
Innovation Solution
A dental handpiece device equipped with multiple camera modules that convert images to electric signals, a processing means to determine visibility of the drilled area, and the ability to switch between camera modules to ensure the area is always visible, using a priority system and a predetermined time suspension before switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single camera module is mounted on the dental handpiece, then the device structure remains simple, but the drilled face may be in a blind spot and cannot be captured
Solution Approach 1:
The patent divides the imaging function into multiple camera modules, each positioned at different locations around the tool mounted part. This segmentation allows the system to capture the drilled face from multiple angles, ensuring no blind spots exist while maintaining manageable complexity through modular design.
Solution Approach 2:
The patent transitions from a single-point imaging approach to a multi-point imaging approach by positioning camera modules at different spatial dimensions around the tool. This dimensional expansion ensures comprehensive coverage of the drilled face from various angles, eliminating blind spots.
2Reliability
If multiple camera modules are mounted to eliminate blind spots, then the visibility of the drilled face improves, but the device complexity increases
Solution Approach 1:
The patent makes the imaging system universal by enabling multiple camera modules to serve the same imaging function. The processing means automatically selects and switches between modules based on the drilling state, allowing any module to serve as the active imaging device while maintaining comprehensive coverage.
Solution Approach 2:
The processing means automatically determines which camera module should be active based on the drilling state and switches between modules without manual intervention. This self-service mechanism reduces operational complexity while ensuring optimal visibility of the drilled face at all times.
3Reliability
If the camera module position is fixed, then the device structure is simple, but the drilled face cannot be captured when in certain positional relationships with the tool and teeth
Solution Approach 1:
The patent introduces dynamic positioning by enabling the system to switch between multiple camera modules based on the drilling state. This dynamic adaptation allows the imaging system to maintain optimal capture capability regardless of the relative positions of the tool, teeth, and drilled face, eliminating fixed-position limitations.
Solution Approach 2:
The patent changes the parameter of camera module selection based on the drilling state. The processing means adjusts which camera module is active according to the positional relationship between the tool, teeth, and drilled face, ensuring optimal capture capability by selecting the appropriate module for each drilling condition.
