Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional CAD practices for housing component design are inflexible and inefficient due to disconnected model data across design stages, making it challenging to adapt and reuse designs with varying parameters, especially for multi-compartment housing components.
Innovation Solution
A method for creating a parametrized multi-compartment housing model using Boolean operations to define bounding volumes, bridging volumes, and topological volumes, allowing for adaptive and reliable interfacing with housed and external components, enabling automatic adjustments based on parameter changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional CAD practices are used for housing component design, then design flexibility is maintained through manual adjustments, but design efficiency deteriorates due to disconnected model data and repeated manual work across design stages
Solution Approach 1:
The housing model is segmented into multiple compartments with independent bounding volumes, each capable of being parameterized and modified independently. This segmentation allows the model to adapt to different design requirements without requiring complete redesign, thereby improving productivity while managing complexity through modular structure
Solution Approach 2:
The parametric housing model serves multiple functions across different design stages (concept design, detailed design, manufacturing) through a unified parameterized structure. The same model framework can accommodate various housed components and external component configurations, eliminating the need for separate manual adjustments at each stage and significantly improving design efficiency
2Adaptability or versatility
If feature parametrization is attempted across multiple design stages, then design adaptability improves, but model reliability deteriorates due to feature failures when relative positions or shell thicknesses are modified
Solution Approach 1:
The housing model employs dynamic parametric relationships where geometric features are defined by parameters that can be modified without causing model failures. The topological volume calculation and Boolean operations create a flexible structure that automatically adapts to changes in relative positions and shell thicknesses, maintaining model reliability while achieving design adaptability
Solution Approach 2:
The invention utilizes parameter changes as the core mechanism for adapting the housing model. By defining the housing through parameters (bounding volumes, shell thicknesses, relative positions) rather than fixed geometry, the model can reliably accommodate design variations. The parametric structure ensures that feature dependencies are maintained through parameter relationships rather than rigid geometric constraints
3Productivity
If disconnected model data is used across design stages, then ease of manufacture is maintained through independent tool usage, but design iteration efficiency deteriorates due to inability to perform automatic adjustments
Solution Approach 1:
The housing model is prepared in advance with a parametric structure that anticipates future design variations. By pre-defining the model with parameterized bounding volumes and topological relationships, the system enables automatic adjustments during design iterations without requiring data reconnection or manual intervention, thus improving iteration efficiency while preserving essential model information

AI summary
A method (700) configures a housing for an assembly via a simulation of the assembly and housing in a computer assisted drafting environment. The assembly includes compartments for components and at least one opening between two neighboring compartments. Based on received parameters (710), aspects of the assembly and the housing are defined, bounding volumes are created (720) for each housing compartment, and bridgings between compartments (730) are defined. A base shell volume of the housing is calculated (740) using Boolean operations on the bounding volumes, and a topological volume is calculated (750) from the base shell volume. A housing assembly model is determined (760) based on the topological volume.
