CAD Manipulating Tool for Dynamic Simulation Initial Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CAD systems require tedious and error-prone numerical input for setting initial conditions in dynamic simulations, such as initial speed and rotation, which can be complex and time-consuming.
Innovation Solution
A computer-implemented method for dynamic simulation in CAD systems that allows users to easily define initial conditions by using a manipulating tool with a three-axis referential, enabling users to input conditions through intuitive actions like mouse movements or direct typing, simplifying the process of setting initial positions, speeds, and accelerations.

Engineering Contradiction Analysis
1Reliability
If users input initial conditions through numerical panels, then initial conditions can be set, but the operation becomes tedious and error-prone
Solution Approach 1:
The patent replaces the mechanical interaction of manually typing numerical values into panels with a graphical user interface that uses visual icons and interactive elements. Users click on graphical representations of objects and parameters rather than manually entering numbers, substituting the mechanical typing action with graphical selection and interaction.
Solution Approach 2:
The patent introduces an intermediary layer between the user and the numerical data. Instead of directly inputting numbers into panels, users interact with graphical icons that mediate the input process. This intermediary graphical interface translates user actions into the appropriate numerical initial conditions, reducing errors and improving ease of use.
2Reliability
If users enter multiple numerical parameters for initial conditions, then complete simulation setup is achieved, but time consumption increases
Solution Approach 1:
The patent performs preliminary actions by pre-configuring the graphical interface with all necessary initial condition parameters displayed as interactive icons. Rather than requiring users to sequentially find and fill multiple panels, all parameters are prepared in advance and presented in a single accessible view, allowing users to quickly set complete initial conditions.
Solution Approach 2:
The patent creates a universal graphical interface that handles multiple types of initial conditions (position, velocity, acceleration, rotational parameters) through a single unified panel. This multi-functional interface consolidates what would otherwise require multiple separate input locations into one comprehensive interaction point, reducing the time needed to set up complete simulation parameters.

AI summary
A computer-aided design system and computer-implemented method define initial conditions for dynamic simulation of an assembly of objects in a three-dimensional scene of a computer-aided design. The system and method provide (S1) the assembly of objects with information relative to kinematic joints linking objects of the assembly. The system/method provide (S2) a manipulating tool (M) embedded in the scene; attach (S3) said manipulating tool (M) to one object of the assembly; select (S4) a degree of freedom of the manipulating tool (M) attached to the object of the assembly; and input (S5) at least one initial condition (IC) according to said selected degree of freedom, an initial condition comprising an initial position and/or an initial speed and/or an initial acceleration. The tool has a referential (reference) with three-axes allowing for each axis a degree of freedom in translation and a degree of freedom in rotation. Next the system and method calculate (S6) and display in real time the dynamic simulation taking into account the initial conditions (IC) previously defined.
