Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If sensitive detonable booster formulations classified as explosives are used, then sufficient detonation pressure is achieved, but supply chain and transport challenges arise
Solution Approach 1:
The booster is divided into two separate components: a non-explosive detonable formulation contained in a hollow body, and a separate explosive initiator (detonator). This segmentation allows the main booster material to be transported and stored without explosive classification restrictions, while the explosive initiator is contained in a separate, controlled component.
Solution Approach 2:
The non-explosive detonable formulation acts as an intermediary between the explosive initiator and the bulk explosive. It is initiated by the explosive initiator to generate sufficient detonation pressure, thereby mediating the energy transfer while avoiding the need to transport classified explosives in the main booster body.
2Ease of manufacture
If non-explosive detonable booster formulations are used, then supply chain and transport challenges are overcome, but achieving sufficient detonation pressure becomes difficult
Solution Approach 1:
The invention combines a non-explosive detonable formulation with a separate explosive initiator to achieve the benefits of both: the ease of handling and transport of non-explosive materials, and the sufficient detonation pressure generation capability of explosive initiators.
Solution Approach 2:
The non-explosive detonable formulation is prepared and positioned in advance in the hollow body, ready to be initiated. This preliminary preparation allows the system to be assembled and transported without classified explosives, while maintaining the capability to generate sufficient detonation pressure when initiated by the explosive initiator.
3Shape
If the initiator channel is centrally located, then structural symmetry is maintained, but the initiator may not be in optimal initiating proximity to the booster formulation
Solution Approach 1:
The initiator channel is deliberately positioned asymmetrically, radially offset from the central longitudinal axis of the hollow body. This asymmetric positioning ensures that the explosive initiator is located in optimal proximity to the non-explosive detonable formulation for reliable initiation, prioritizing functional effectiveness over structural symmetry.

Function Achieved in This Case

Implementation Method 1
BOOSTERS IN THE CONTEXT OF THE EXPLOSIVES INDUSTRY (i.e. 'explosive boosters') are used to generate, through detonation of a sensitive detonable booster formulation, sufficient detonation pressure to initiate and thus cause detonation of a less sensitive bulk explosive

AI summary
An explosive booster for initiating, and thus causing detonation of, a bulk explosive, includes a hollow body comprising a base member and a sidewall projecting from the base member. The body defines an interior space between the base member and the sidewall for containing a detonable booster formulation in use. A hollow elongate initiator locating formation projects longitudinally into the interior space at least from the base member and defines an initiator channel that is open through the base member, for locating an explosive initiator in initiating proximity relative to a detonable booster formulation contained in the interior space in use. The initiator channel extends longitudinally along a central longitudinal axis thereof that is radially spaced from, and parallel to, a central longitudinal axis along which the interior space longitudinally extends.
