LG Chooses 3DCS Tolerance Analysis

Camera Lens Fit Analysis - Use Case

Not a Customer Model - Model used for demonstration purposes only

Issue: Variation in lens connections causing build and functional issues.

Solution: Simulation in 3DCS of assembly determined contributors and true cause of variation.

Results: Basic design change and simulation validation produced a reduction in overall assembly variation, greatly reducing the chance of assembly build failures.

Laptop Internal Component Variation Analysis - Use Case

Issue: Variation of Internal components of laptop causing assembly build issues – hard drive, mother board, ram chips, etc… - Limited space inside of Laptop case creates very little room for variation. Changes in components from manufacturing variation were causing cases where the components did not all fit inside the case, or close proximity caused thermal issues.

Solution: Simulating the assembly sequence with variation taken into account provided new insight into the source of the variation and primary trouble areas. Making minor design alterations, and rerunning the analysis validated improvements to the assembly process. 

Results: With basic design changes to the placement of the components, the current amount of variation was accounted for, requiring very little adjustment in tolerances.
