Vehicle Design Generation Through Geometric and Physical Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual design process for vehicles, such as aircraft, is time-consuming and inefficient, as it often requires significant processing power for analysis, limiting the consideration of potentially viable designs.
Innovation Solution
A computer-implemented method using geometric and physical constraints to generate and filter vehicle designs, reducing the number of designs through automated filtering based on geometric and physical constraints, allowing for efficient processing and user interaction.

Engineering Contradiction Analysis
1Productivity
If manual design process is used with user judgement, then design quality may be maintained, but design time becomes very long and processing power requirements limit the number of designs that can be considered
Solution Approach 1:
The system performs preliminary filtering of designs based on geometric constraints before detailed analysis. By pre-generating multiple designs with varying geometric properties and filtering them according to specified constraints, the system reduces the number of designs requiring full analysis, thereby reducing overall processing time while maintaining design quality
Solution Approach 2:
The system creates multiple copies of base vehicle designs with modified geometric properties. Instead of manually creating each design variant, the system automatically generates numerous copies with different geometric parameters, filters them using constraints, and identifies viable options, dramatically increasing productivity
2Measurement precision
If comprehensive analysis tools are used on vehicle designs, then design accuracy and constraint satisfaction improve, but processing power requirements become prohibitive for large numbers of designs
Solution Approach 1:
The analysis process is segmented into two stages: first, rapid filtering based on geometric constraints; second, detailed analysis using comprehensive tools only on filtered designs. This segmentation allows the system to maintain measurement precision for constraint satisfaction while reducing processing power consumption by applying intensive analysis only to a subset of designs
Solution Approach 2:
The system applies partial analysis (geometric constraint checking) to all generated designs, and excessive/detailed analysis (comprehensive analysis tools) only to designs that pass the initial filter. This approach ensures adequate constraint satisfaction through the partial action of geometric filtering while avoiding the excessive processing power consumption that would result from applying comprehensive analysis to all designs

AI summary
A computer-implemented method of generating one or more designs for a vehicle, using a vehicle modelling application arranged to generate a three-dimensional model of a vehicle from a vehicle model definition, the vehicle model definition defining a set of values for geometric properties of the vehicle. A set of vehicle model definitions is generated, each vehicle model definition satisfying a set of geometric constraints. The set of vehicle model definitions is then filtered by generating the three-dimensional model of a vehicle from a vehicle model definition using the vehicle modelling application, determining whether the three-dimensional model satisfies a first set of physical constraints, and if the three-dimensional model does not satisfy the set of physical constraints, removing the vehicle model definition from the set of vehicle model definitions.
