MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641041509 A) filed by Anin Technologies Private Limited, Bangalore, Karnataka, on April 1, for 'topology-aware hybrid constraint management and solving system for computer-aided design (cad).'
Inventor(s) include Dibyalochana Sahoo.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "A computer-implemented system and method for managing and solving geometric constraints in a computer-aided design (CAD) environment is disclosed. The system integrates topology-aware constraint detection with hybrid constraint management by combining explicitly defined user constraints and implicitly inferred geometric constraints. Geometric entities are translated into a unified solver representation via a variable abstraction layer capable of handling heterogeneous entity types. The system automatically detects coincident and relational geometric features and dynamically generates constraints that are integrated into a unified nonlinear optimization framework. The solver employs adaptive stabilization techniques including damping, scaling, step control, and rollback recovery. A best-state preservation mechanism ensures solution robustness under ill-conditioned scenarios. The computed solution is mapped back to geometry in real time, enabling stable, scalable, and user-friendly parametric modeling. The invention significantly improves robustness, automation, and computational reliability in CAD systems."
