Factory ID Object Creation Eliminates Redundant Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The factory pattern in object-oriented programming is inflexible and often results in the creation of redundant interfaces, limiting the ability to create objects without specifying the exact class, which restricts flexibility and abstraction in object creation.
Innovation Solution
A factory identification system that uses factory IDs to differentiate between objects, allowing for the creation of objects based on these IDs and additional construction parameters, thereby configuring classes or prototypes with factory IDs rather than interfaces, enabling more flexible object creation without redundant interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the traditional factory pattern uses interfaces to create objects, then abstraction is provided, but flexibility is limited and redundant interfaces are created
Solution Approach 1:
The patent changes the parameter used for object creation from interface-based to identifier-based. Instead of requiring code to specify concrete classes or implement multiple interfaces, the factory now accepts simple string identifiers (factory IDs) that map to objects. This parameter change eliminates the need for redundant interfaces while maintaining abstraction, as the factory internally handles the mapping between identifiers and object instances.
2Loss of information
If the factory pattern specifies concrete classes, then object creation is direct, but abstraction between code and implementation is lost
Solution Approach 1:
The patent introduces an intermediary mechanism - the factory ID system - that sits between the code and the concrete object implementation. The factory acts as a mediator that receives simple identifier requests from code and translates them into appropriate object instances internally. This intermediary layer preserves abstraction by hiding the concrete class details while maintaining ease of operation through simple identifier-based requests.
3Manufacturing precision
If multiple interfaces are created to handle different object types, then object differentiation is achieved, but system complexity increases
Solution Approach 1:
The patent makes the factory universal by enabling a single factory to handle multiple object types through identifier-based differentiation. Instead of creating separate interfaces for different object types, the factory uses factory IDs to distinguish between object types and return appropriate instances. This multi-functional approach maintains precise object differentiation while eliminating the need for multiple interfaces, reducing system complexity.

AI summary
The described technology is directed towards a factory identification system, in which a factory object is provided with a factory identifier (ID) that specifies information regarding a desired object that is more specific than specifying an interface. Additional construction parameters such as an object ID may be provided to further describe the desired object. Also described are object caching and reuse, and tagging the object with information that may be preserved and later used to recreate an object.
