Abstract

To set up the future research and development direction for Auger bit, this study analyzed publicized patent trends of Deep Cement Mixing method (DCM) in Korea, USA, Japan, and Europe. DCM method was firstly classified into wing shapes and the number of rods according to the technical scope, and secondly, classified into 8 types according to type of screw and rotation axial. A total of 2,815 patents were searched and 448 validated patents were selected through de-duplication and filtering. As a result of the analysis of the portfolio through the number of patents and growth stages, it was selected as the core technology that auger is deemed to have high growth potential and if there is a patent similar to core technology through a patent barrier analysis, the basic data is suggested to develop the design around and differentiated technologies.

본 연구에서는 오거비트에 대한 향후 연구개발 방향을 설정하기 위하여 전체 심층혼합처리공법에 대한 한국, 미국, 일본 및 유럽에서의 출원 공개/등록된 특허를 중심으로 특허 동향을 분석하였다. 심층혼합처리공법을 대상으로 기술 범위에 따라 1차적으로 날개 형태와 로드의 개수로 분류하고, 2차적으로 스크류 타입과 회전축의 타입에 따라 8가지로 분류하였다. 특허 검색 결과 총 2,815개가 검색되었으며 중복제거 및 필터링을 통하여 448건의 유효 분석대상 특허를 선별하였다. 특허건수와 성장단계를 통한 포트폴리오 분석 결과 성장가능성이 높다고 판단되는 오거를 핵심기술로 선정하였으며, 이에 대한 특허장벽 분석을 통하여 핵심기술과 유사성이 높은 특허가 있을 경우 회피설계 및 타기술과 차별화된 기술 개발을 할 수 있는 기초자료를 제시하였다.
