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

VSEngineering Contradiction Analysis

1Reliability

If manual verification of connections is performed, then connection integrity can be confirmed, but operator time and operational efficiency are reduced

Engineering Contradiction:
Improveconnection integrityVSAvoidoperator time
Core Design Contradiction:
ReliabilityVSLoss of time

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

Inventive Principle:
Principle #25Self-service

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

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If different antenna configurations are used, then system versatility is improved, but manual adjustment of capacitor values is required

Engineering Contradiction:
Improveantenna compatibilityVSAvoidcapacitor adjustment
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

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

Inventive Principle:
Principle #15Dynamics

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

Inventive Principle:
Principle #35Parameter changes

3Productivity

If automatic measurement and adjustment features are added, then operational efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvesetup efficiencyVSAvoidcircuit complexity
Core Design Contradiction:
ProductivityVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #6Universality (Multi-functionality)
