Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual comparison of applications and products is performed, then retrieval accuracy can be improved, but retrieval time and labor requirements increase significantly
Solution Approach 1:
The patent replaces manual mechanical comparison processes with automated computer-based similarity calculation systems. The processing unit automatically calculates similarity degrees between application specifications and product information, eliminating the need for manual review while maintaining high accuracy in identifying related applications and products.
Solution Approach 2:
The patent introduces an intermediary information retrieval system that mediates between the user's query and the database of applications and products. This intermediary system processes queries automatically, calculates similarities, and presents relevant results, thereby reducing the time and effort required for direct manual comparison.
2Loss of information
If comprehensive search of all applications is performed, then retrieval completeness is improved, but system complexity and processing load increase
Solution Approach 1:
The patent extracts and processes only the essential information needed for similarity calculation from the comprehensive database. By focusing on key attributes such as application specifications, claims, and product information, the system achieves complete retrieval of relevant data while avoiding the complexity of processing all unnecessary details from the entire database.
Solution Approach 2:
The patent segments the complex retrieval task into manageable stages: first calculating similarity between application specifications, then filtering based on claim overlap, and finally verifying product relationships. This segmentation allows the system to handle comprehensive searches systematically without overwhelming complexity.
3Measurement precision
If detailed analysis of each application-specification pair is performed, then retrieval precision is improved, but processing time increases
Solution Approach 1:
The patent replaces detailed manual analysis with automated computational similarity calculations. The processing unit uses algorithmic approaches to quickly determine similarity degrees between application specifications and product information, achieving both high precision in matching and fast processing speeds simultaneously.

AI summary
An information retrieval system that is capable of retrieving a similar application and value information of the similar application for a designated application is provided. An information retrieval system is provided that receives a designated application, calculates a first degree of similarity between a specification of the designated application and each of specifications of a plurality of applications, extracts a plurality of first similar applications from the plurality of applications on the basis of the first degree of similarity, calculates a second degree of similarity between a support drawing corresponding to the scope of claims of at least one of the plurality of first similar applications and at least one drawing of the designated application, extracts at least one drawing similar to the support drawing of at least one of the plurality of first similar applications from the drawings of designated application on the basis of the second degree of similarity, and outputs value information, the support drawing, and the similar drawing for at least one of the plurality of first similar applications. Related product information or the like can be given as the value information.
