Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current three-dimensional scanning systems face challenges in achieving precise scanning of objects, particularly for applications like hearing aids and dental implants, due to systematic or random errors in calibration and performance, which limits their use in modeling such implants and shells.
Innovation Solution
An object feeder system with a scanning plate assembly featuring tracks and object holders that can be moved between a parking area and a scanning area, allowing for automated and efficient positioning of objects within the scanner for optimal scanning results, reducing human error and improving precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If objects are manually positioned on the scanning plate, then the operator has flexibility in placement, but positioning precision and consistency deteriorate due to human error
Solution Approach 1:
The system uses automatic object detection and self-positioning algorithms that enable the scanning plate to autonomously identify objects and adjust their positions without manual intervention, thereby achieving high positioning precision while eliminating manual placement operations
Solution Approach 2:
The patent replaces manual mechanical positioning with an automated control system that uses sensors, algorithms, and motorized actuators to achieve precise object placement, substituting human operation with an automated mechanical-electrical system
2Productivity
If multiple objects are scanned sequentially without automated positioning, then the scanning process is simple, but scanning efficiency and productivity deteriorate
Solution Approach 1:
The system performs preliminary object detection and positioning before the actual scanning process, pre-arranging multiple objects on the scanning plate in optimal positions, which enables efficient sequential scanning without requiring complex real-time adjustments during scanning
Solution Approach 2:
The scanning plate is designed with multi-functionality, serving both as a positioning platform and a scanning surface, while integrating object detection and positioning capabilities into a single device, thereby improving productivity without proportionally increasing system complexity
3Reliability
If the scanning plate lacks automated positioning, then the device structure remains simple, but scanning precision and reliability worsen due to inconsistent object placement
Solution Approach 1:
The system incorporates feedback mechanisms where sensors detect object positions and the control system continuously adjusts positioning based on detected deviations, ensuring consistent scanning reliability while managing system complexity through closed-loop control
Solution Approach 2:
The patent employs parameter changes in the positioning system, such as adjustable motor speeds, variable positioning forces, and dynamic scanning parameters, to optimize scanning reliability across different object types without requiring overly complex hardware
