Wireless Detonator Capacitor Bank for Automated Connection Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless detonator systems require manual verification of connections between a capacitor bank and an antenna, which is inefficient and time-consuming, especially when dealing with different antenna configurations with varying inductance values.
Innovation Solution
A portable apparatus with a housing containing a capacitor bank, measurement circuit, and a processor that automatically measures connection integrity and adjusts capacitor values for optimal performance, using a switching circuit to ensure reliable connections and tuning, with visual feedback and optional automation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification of connections is performed, then connection integrity can be confirmed, but operator time and operational efficiency are reduced
Solution Approach 1:
The capacitor bank apparatus performs self-verification of connection integrity through integrated measurement circuits that automatically test connections between the capacitor bank and antenna, and between the capacitor bank and transmitter, eliminating the need for manual operator verification
Solution Approach 2:
Manual mechanical connection verification by operators is replaced with automated electrical measurement circuits that electronically assess connection integrity, providing objective and consistent verification without human intervention
2Adaptability or versatility
If different antenna configurations are used, then system versatility is improved, but manual adjustment of capacitor values is required
Solution Approach 1:
The capacitor bank system transitions from static fixed capacitor values to dynamic adjustable capacitor values that can be automatically modified based on the specific antenna configuration being used, enabling adaptive optimization without manual intervention
Solution Approach 2:
The capacitance values are automatically adjusted based on measurements of the connected antenna's inductance, allowing the system to optimize its electrical parameters for different antenna configurations without requiring manual operator intervention
3Productivity
If automatic measurement and adjustment features are added, then operational efficiency is improved, but device complexity increases
Solution Approach 1:
The measurement circuits and capacitor adjustment mechanisms are integrated directly into the capacitor bank apparatus itself, combining multiple functions (measurement, analysis, and adjustment) into a single unified device rather than requiring separate external equipment
Solution Approach 2:
The capacitor bank apparatus is designed to perform multiple functions: storing electrical energy, measuring connection integrity, measuring antenna inductance, calculating optimal capacitance values, and automatically adjusting capacitor configurations, making it a multi-functional integrated system
