Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating processing or manufacturing steps in medical and industrial applications are costly, resource-intensive, and prone to errors, requiring frequent use of new artificial bones or human specimens and extensive use of computer tomography for each test run, which is time-consuming and increases susceptibility to inaccuracies.
Innovation Solution
A method involving the creation of modified model data for an object, which includes positioning processing lines and target disks within a 3D model, defining an exchange volume, and manufacturing a modified object using additive techniques, allowing for precise evaluation and testing of processing steps without the need for frequent new specimens or extensive imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If new artificial bones or human specimens are used for each test run, then evaluation accuracy is maintained, but costs and resource consumption increase significantly
Solution Approach 1:
The patent creates a copy of the relevant object portion with integrated target disks that can be reused multiple times. Instead of consuming new specimens for each test, the same modified model with target disks is replicated and used repeatedly, maintaining evaluation accuracy while eliminating the need for continuous new materials
Solution Approach 2:
The target disks are pre-integrated into the modified model during the modeling phase, before actual testing begins. This preliminary preparation creates a ready-to-use test object that eliminates the need for repeated specimen preparation and reduces resource consumption across multiple test runs
2Measurement precision
If computer tomography is used for evaluation of each test run, then detailed evaluation data is obtained, but time consumption and error susceptibility increase
Solution Approach 1:
The patent replaces physical imaging processes with a digital 3D model that already contains the target disk positions. Instead of performing time-consuming computer tomography scans to determine target positions, the model provides this information directly, dramatically reducing evaluation time while maintaining precision
Solution Approach 2:
The patent substitutes the mechanical/imaging-based computer tomography system with a computational 3D modeling approach. The target disk positions are determined through software-based 3D modeling and coordinate calculations rather than physical scanning, eliminating the time and errors associated with imaging processes
3Ease of operation
If graphical evaluation aids are used for digital evaluation, then evaluation capability is provided, but error susceptibility increases
Solution Approach 1:
The patent uses precise 3D coordinate data from the digital model as the evaluation reference, rather than visual graphical aids. The target disk positions are defined by exact numerical coordinates in the 3D model, eliminating the visual interpretation errors and subjectivity inherent in graphical evaluation methods
