    • PROBLEM TO BE SOLVED: To provide a declarative system for designing parts or assemblies of parts based on a history-based design system. SOLUTION: A system (40) has a storage format with primitives and operations. A modeled object is defined in the history-based design system by an ordered sequence of operations and primitives. This declarative system has several functional features. Such functions may be selected (48) and instantiated by an end user. An instantiated functional feature provides contributions (50). Each contribution is an ordered sequence of operations and primitives of the history-based design system. The contributions (50) are received by a seed structure (52). An editor (56) edits the seed structure according to the grammar. COPYRIGHT: (C)2009,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a computer implemented method for designing a part modeled by using: a seed structure of a context-free grammar; a set of rules of the grammar, at least two design features; each design feature being defined by at least one rule of the set; and a priority order between the design features determined by the seed structure and the set of rules. SOLUTION: The method comprises the steps of: displaying a representation of the part in a graphical user interface according to the priority order; modifying the priority order between the two design features by modifying the set of rules; and displaying a representation of the part according to the modified priority order.

    • PROBLEM TO BE SOLVED: To provide a computer-implemented method intended for designing an assembly of a plurality of objects. SOLUTION: The assembly is modeled by a directed acyclic modeling graph having nodes and arcs. Each node represents an object of the assembly. Each arc represents the use of an end node by an origin node. At least one arc is uniquely identified by an identifier. The assembly is further modeled by at least one relation having at least one tuple containing a first chain of at least one identifier. The method includes a step of determining at least one mapping between the first chain and a second chain of at least one identifier and a step of substituting at least one occurrence of the first chain in the tuple of the relation with the second chain. The invention thus provides a means to repair broken tuples automatically and to facilitate design. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:提供旨在设计多个对象的组件的计算机实现的方法。 解决方案:组件由具有节点和弧的有向非循环建模图建模。 每个节点表示装配体的一个对象。 每个圆弧表示由起始节点使用结束节点。 至少一个弧由标识符唯一地标识。 组件进一步由具有至少一个包含至少一个标识符的第一链的元组的至少一个关系建模。 该方法包括确定至少一个标识符的第一链和第二链之间的至少一个映射的步骤,以及用与第二链的关系的元组中的至少一次出现第一链的步骤。 因此,本发明提供了一种自动修复断开的元组并方便设计的手段。 版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To improve robustness of a computer-implemented method of design of ruled surfaces. SOLUTION: The method of design of ruled surfaces includes steps (S110 and S120) of accessing data defining guiding curves P(u) and Q(v) and a cost function f(t, w), and an unknown coupling curve is a parameterized curve s¾→(t(s), w(s)). The method includes a step (S200) of defining an objective function of a type J=J(f, t, w) using both f(t, w) and coordinates t, w of the coupling curve. Then, optimizing the objective function J makes it possible to obtain a target coupling curve (S400). Finally, a ruled surface S(s, λ)=λQ(w(s))+(1-λ)P(t(s)) is provided (S500), according to guiding curves P(t(s)) and Q(w(s)), composed with the coordinates t, w of the coupling curve previously obtained.
