Electronic Authorization Device for Hand-Held Power Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for authorizing the use of hand-held power tools lack flexibility and reliability, leading to potential unauthorized use and compromised work safety, as they do not adequately account for user-specific information, environmental conditions, and real-time adaptations in access permissions.
Innovation Solution
An electronic authorization device with an evaluation unit that provides authorization information based on use-related information, including user identity, training level, environmental conditions, and equipment status, using sensors and data exchange with infrastructure units to ensure secure and adaptive access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authorization methods are used for hand-held power tools, then the system is simple to implement, but the authorization lacks flexibility and reliability
Solution Approach 1:
The authorization system is segmented into multiple independent evaluation units, each responsible for assessing specific aspects (user identity, training level, environmental conditions, equipment status). This modular approach enhances reliability through comprehensive evaluation while managing complexity by dividing the system into manageable components.
Solution Approach 2:
The authorization system transitions from static permission settings to dynamic real-time evaluation. The evaluation units continuously assess current conditions and adapt authorization decisions accordingly, improving reliability by responding to actual system state rather than predetermined rules.
2Reliability
If comprehensive use-related information is evaluated for authorization, then work safety is improved, but the processing time and system complexity increase
Solution Approach 1:
User-specific information such as identity, training level, and authorization credentials are pre-registered and stored in the system before actual use. This preliminary preparation enables rapid real-time evaluation during operation, ensuring comprehensive safety checks without delaying the authorization process.
Solution Approach 2:
The system replaces manual authorization processes with automated electronic evaluation units that rapidly process multiple parameters simultaneously. This substitution of mechanical/manual procedures with electronic automation reduces processing time while maintaining comprehensive safety evaluation.
