Parametric 3D Object Positioning for Complex Assembly Constraint Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The design of complex assemblies, such as airplanes, faces challenges in dynamically managing the positioning of multiple elements across various disciplines, leading to delays and a lack of overall understanding due to the sequential and static nature of traditional analysis processes.
Innovation Solution
A method utilizing parametric models to select, display, and position objects relative to each other, with dynamic management of constraints, allowing for rapid analysis of modifications and visualization of their effects, facilitated by software like Catia for 3D design and parameter editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sequential partial analyses are used for positioning elements across different disciplines, then each discipline can validate its specific criteria, but the process results in considerable delays and lacks dynamic management capability
Solution Approach 1:
The patent merges multiple discipline-specific validation processes into a single integrated computer program product that simultaneously handles positioning criteria from aerodynamics, structures, propulsion, and other disciplines. This integration allows all validations to occur in parallel rather than sequentially, eliminating the time delays caused by passing files between different specialists while maintaining the reliability of each discipline's specific criteria validation.
Solution Approach 2:
The patent implements dynamic management capability through a computer program that can实时 (real-time) update and re-evaluate positioning criteria when modifications are made. The system dynamically adjusts the positioning study based on input data from multiple disciplines, allowing the process to adapt and respond to changes immediately rather than requiring repeated sequential cycles of validation.
2Reliability
If multiple disciplines participate in the positioning study with successive partial analyses, then comprehensive validation is achieved, but it becomes impossible to manage the process dynamically
Solution Approach 1:
The patent creates a universal computer program product that serves multiple functions: it integrates positioning criteria from all disciplines, performs comprehensive validation, and provides dynamic management capability. This single multi-functional system replaces the complex multi-step process of successive partial analyses, reducing process management complexity while maintaining comprehensive validation across all disciplines through a unified interface.
3Reliability
If successive partial analyses are conducted by different specialists, then each discipline's criteria are validated, but there is a lack of overall view that would permit simple understanding of inter-disciplinary problems
Solution Approach 1:
The patent merges all discipline-specific validation results and positioning data into a single integrated computer program product that provides a comprehensive overall view. This unified system displays and manages all positioning criteria from different disciplines simultaneously, allowing users to understand the interrelationships between aerodynamic, structural, propulsion, and other considerations without losing the specific validation requirements of each discipline.
Data Source
AI summary
A method aiding in relative positioning of 3D objects, in a complex environment involving several techniques, according to a set of geometrical and/or mathematical constraints. A parametric model is selected for each of the objects, parametric models including models of the constraints are also selected. A representation of one of the objects is displayed, permitting positioning of another object and the display of a representation of the positioning. A piece of data relating to the position of one of the objects is accessed for each parametric model including a constraint modeling and a piece of data relating to the position of one of the objects is accessed to permit an evaluation of the corresponding constraint. When an object is added or displaced the relative positions of the objects and the constraints are reevaluated.
