Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic components are integrated into a single circuit board, then the functionality and capacity of the detonator are enhanced, but the available space within the detonator housing is limited
Solution Approach 1:
The patent employs a three-dimensional stacked configuration of multiple circuit boards arranged vertically within the detonator housing. This multidimensional layout allows logic circuits, data processors, sensors, and other electronic components to be distributed across multiple layers, effectively increasing the functional capacity without expanding the horizontal footprint. The vertical stacking approach transforms a two-dimensional space constraint into a three-dimensional solution, accommodating complex electronics within the limited cylindrical housing volume.
2Adaptability or versatility
If complex electronic components are added to the detonator, then the functionality is enhanced, but the device complexity increases
Solution Approach 1:
The patent divides the electronic system into multiple separate circuit boards, each dedicated to specific functions such as logic circuits on one board, data processors on another, and sensors on a third board. This segmentation allows each component to be independently designed, tested, and replaced without affecting the entire system. The modular architecture reduces overall device complexity by organizing complex functionality into manageable, discrete units that can be maintained separately.
3Strength
If the detonating capsule is permanently connected to the housing, then the structural integrity is improved, but the ease of assembly and disassembly is reduced
Solution Approach 1:
The patent implements a dynamic retention mechanism using resilient arms with tabs that can be selectively engaged with the detonating capsule. These resilient arms provide a firm holding force during normal operation to ensure structural integrity, but can be easily disengaged by applying outward force to release tabs. This dynamic connection allows the system to transition between a securely locked state for operational reliability and an easily accessible state for assembly and maintenance, eliminating the need for permanent rigid connections.

AI summary
A detonator includes a detonating capsule, a detonator head storing an electronic circuit board, and a retaining arm configured to fix the detonating capsule to the detonator head. The electronic circuit board is a multidimensional circuit board that extends from the detonator head into engagement with the detonating capsule.
