Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional object creation in programming languages is tedious and inefficient, requiring statement-based approaches and leading to compiler execution bottlenecks due to the need for explicit imperative statements and excessive overloading, which limits the ability to define complex object instances and reduces programming efficiency.

Innovation Solution

The introduction of a syntax component and initializer component that facilitate expression-based object creation, allowing for the use of object and collection initializers to initialize newly-created entities, reducing overloading and enabling code inferencing to generate efficient constructor calls and projections, thus simplifying the creation of complex object instances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If statement-based object creation is used, then object instances can be created with explicit control, but programming becomes tedious and compiler execution is severely impacted

Engineering Contradiction:

Improveease of object creationVSAvoidcompiler execution efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent replaces the mechanical statement-based object creation system with an expression-based system. Instead of requiring sequential imperative statements to create and initialize objects, the invention allows object creation to be expressed as concise expressions that can be evaluated and executed more efficiently by the compiler, thereby improving both ease of operation and compiler execution efficiency

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the fundamental parameter of object creation from statement-based to expression-based. This parameter change transforms the nature of the operation from a multi-step procedural sequence to a single evaluatable expression, reducing the computational overhead and improving compiler performance while maintaining full functionality

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If traditional object constructors with overloading are used, then objects can be created with parameters, but the number of overloads becomes excessive (2n combinations) and definition becomes inconvenient

Engineering Contradiction:

Improveobject construction flexibilityVSAvoidconstructor overload complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by creating a single expression-based object creation mechanism that can handle all parameter combinations. Instead of requiring multiple overloaded constructors to cover different parameter scenarios, the invention provides a universal expression syntax that adapts to any number and type of parameters, eliminating the need for 2n overload combinations while maintaining full construction flexibility

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent inverts the traditional approach by allowing the object creation expression to specify only the parameters that need to be set, rather than requiring the constructor to define all possible parameter combinations. This inversion shifts the complexity from the constructor definitions to the expression syntax, reducing the number of constructors needed while maintaining adaptability

Inventive Principle:

Principle #13The other way round (Inversion)

3Productivity

If expression-based syntax is used, then programming efficiency is enhanced and compiler performance improves, but syntax extension is required

Engineering Contradiction:

Improveprogramming efficiencyVSAvoidsyntax component complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the object creation process into distinct expression components that can be independently parsed and evaluated. By dividing the creation expression into separable elements (object instantiation, property assignment, initialization), the syntax extension becomes more manageable and less complex, while still achieving improved programming efficiency and compiler performance

Inventive Principle:

Principle #1Segmentation

AI summary

Syntax for creating object instances utilizing expressions instead of statements. A syntax component facilitates extension of conventional object-creation-expression syntax. An initializer component provides for initialization of a newly-created entity via object and collection initializers. The initializer component provides initialization of the newly-created entity utilizing an object initializer where the object initializer specifies values for one or more fields or properties of the newly-created entity which is an object, and consists of a sequence of member initializers enclosed by tokens and separated by commas. The initializer component can also provides initialization of the newly-created entity utilizing a collection initializer when the underlying object implements a certain interface or implements a certain pattern. An overloading constructor can be called as part of the initialization process. In another aspect, code inferencing is disclosed whereby given a type, the corresponding code can be inferred by the compiler and inserted for compiling by a compiler.
