Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods use charge mass ratio to case mass for conversion, then the calculation is simple, but the evaluation accuracy is low due to neglecting mass distribution and material performance
Solution Approach 1:
The patent replaces conventional mechanical calculation methods with an experimental test system that uses controlled explosions, pressure sensors, and data acquisition systems to directly measure and evaluate damage effectiveness, thereby achieving high accuracy without relying on simplified mass ratio calculations
Solution Approach 2:
The patent introduces a target plate as an intermediary element between the explosive charge and the case, which serves as a measurable indicator of damage effectiveness. The target plate's response provides objective data for evaluation, bridging the gap between complex internal explosion dynamics and quantifiable results
2Measurement precision
If conventional methods evaluate damage with charge mass, then the evaluation is straightforward, but the result has large error because case absorbs energy during detonation
Solution Approach 1:
The patent extracts the energy absorption effect of the case from the overall system by using a standardized target plate that isolates and measures only the damage transmission through the case, allowing separate evaluation of case energy absorption and explosive damage effectiveness
Solution Approach 2:
The patent implements a feedback mechanism where pressure sensors mounted on the case interior surface detect pressure changes during detonation, providing real-time data on energy absorption that feeds back into the evaluation system to correct and refine damage effectiveness calculations
3Adaptability or versatility
If no specific indexes are used for inhibition effectiveness, then the evaluation system is simple, but the inhibition effectiveness of warhead cannot be evaluated effectively in varying atmospheres
Solution Approach 1:
The patent designs a universal test system with standardized components (pressure sensors, data acquisition systems, target plates) that can evaluate warhead performance across multiple atmosphere types (air, water mist, anoxic environments) using the same basic apparatus, thereby achieving high adaptability without proportionally increasing complexity
Solution Approach 2:
The patent evaluates inhibition effectiveness by changing atmospheric parameters (oxygen concentration, humidity, pressure) and measuring their effect on detonation performance through standardized metrics, allowing systematic comparison of warhead behavior across different atmosphere conditions

AI summary
A method for evaluating a damage power of confined explosion, includes: determining a size of a confined case and a thickness of a target plate according to a requirement of evaluation on damage effectiveness of a warhead to establish an explosive damage effectiveness evaluation platform; calibrating parameters of the platform with a series of confined explosion tests of trinitrotoluene (TNT) bare charges in the case to form a relational map, in which a deflection of a mid-point of the target plate changes with a charge mass; obtaining a deflection of the mid-point of the target plate by detonating different warheads, forming different detonation atmosphere and forming different venting configuration in the case, and performing interpolation through the map to obtain an equivalent bare charge as an evaluation index. The method quantitatively evaluates the damage effectiveness of the warhead, and is not limited by the damage component.
