Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If powerful batteries are used to meet energy requirements, then energy storage capacity is improved, but volume occupied increases significantly
Solution Approach 1:
The patent implements nesting by placing the electric detonator inside the battery housing. The detonator is positioned within the cup-shaped recess of the battery housing, allowing the detonator to be nested within the battery structure. This eliminates the need for separate housing for the detonator and optimizes space utilization, reducing the overall volume while maintaining sufficient energy storage capacity.
2Volume of stationary object
If set-back generators are used to reduce space, then volume is reduced, but energy provision becomes insufficient
Solution Approach 1:
The patent utilizes the rotational kinetic energy of the spinning projectile itself to generate electrical energy through an electromagnetic generator. The generator is driven by the rotation of the projectile, converting the kinetic energy already present in the system into electrical energy for the proximity sensor and other components. This self-service approach eliminates the need for separate power storage devices while providing sufficient energy.
3Use of energy by moving object
If magnetic proximity sensor is used, then energy requirement is reduced, but detection capability is limited
Solution Approach 1:
The patent implements a multi-functional electromagnetic generator that serves dual purposes: it generates electrical energy for the proximity sensor and other components, and it also functions as the proximity sensor itself. The generator detects changes in electromagnetic field caused by the proximity of ferromagnetic targets, combining the functions of power generation and target detection in a single component, thereby providing both energy and versatile detection capability.
