Innovative Design of Pin Tumbler Lock Based on TRIZ

Article Preview

Pin tumbler lock is widely used due to its important role in security. However, the existing pin tumbler locks are not safe enough as they can be easily opened by many specific tools. Although many pin tumbler lock patents have been proposed to enhance the security level, these revealed designs still exhibit different deficiencies. In addition, the traditional method for lock designing is of low efficiency as it is based on inspiration and experience. Therefore, the TRIZ tool, which is the inventive problem solving method, is applied to lock designing in this paper. An innovative design of magnetic pin tumbler lock has been proposed through analyzing the traditional pin tumbler lock system, finding contradictions and solving them by using TRIZ tools such as separation principle, inventive principle, contradiction matrix and substances - field analysis. The proposed magnetic pin tumbler lock is double encoded and can effectively prevent specific tools from opening.
