Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for designing support structures for sheet metal parts during assembly and gaging are often deficient, leading to instability issues that can result in improper support and potential damage during manufacturing and quality control processes.
Innovation Solution
A computer-implemented method for simulating and designing support structures that includes displaying a visual representation of sheet metal parts and support elements, allowing users to interactively place elements, automatically determining stability status, and iteratively adjusting placements until the part is stably held, ensuring the arrangement is satisfactory for real-world implementation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If support elements are placed manually in a computer aided design system, then the design process is simple and interactive, but the resulting arrangement may be deficient and unstable
Solution Approach 1:
The system automatically calculates and provides feedback on the stability status of the support structure arrangement to the user. This feedback mechanism allows users to iteratively adjust their manually placed support elements until the arrangement achieves satisfactory stability, thereby resolving the contradiction between simple interactive design and reliable stable support.
2Productivity
If support elements are placed without stability analysis, then the design process is faster, but the implementation may not properly support the part
Solution Approach 1:
The system performs preliminary stability analysis during the design phase by automatically calculating stability status based on support element positions and orientations. This preliminary action identifies potential stability issues before real-world implementation, allowing designers to correct problems in the virtual model rather than discovering them during physical assembly or operation.
3Ease of operation
If manual design of support structures is used, then user control is high, but detection of stability issues is difficult
Solution Approach 1:
The system replaces manual mechanical assessment of support structure stability with an automated computational analysis. The computer automatically calculates stability status by evaluating the geometric relationships between support elements and the sheet metal part, substituting complex manual stability analysis with algorithmic computation that is both accurate and efficient.

AI summary
A computer-implemented method for simulating and designing a support structure (2) for assembling or gaging a sheet metal part (1) comprises, in a simulation of the sheet metal part (1) and support structure (2), designing a selection of support elements (3) and a position and orientation of the support elements (3) by displaying a computer based visual representation (5) of the sheet metal part (1) to a user. According to a user input, support elements (3) are placed relative to the sheet metal part (1). The method further comprises automatically determining a stability status indicating whether the sheet metal part (1) is stably held by the support elements (3), and displaying the stability status to the user.
