Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current detonator supports are used with multiple components for secure attachment, then attachment reliability is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent combines multiple functional components into a single integrated detonator support device. The housing unifies the detonator unit, latching mechanism, and cord engagement features into one compact structure, eliminating the need for separate components and simplifying operation while maintaining secure attachment through the integrated latching system
Solution Approach 2:
The detonator support device is designed with universal features that allow it to function in various borehole orientations and configurations. The latching mechanism and cord clamping surfaces are positioned to engage with detonation cords regardless of borehole direction, making the device adaptable to different blasting applications without requiring orientation-specific configurations
2Reliability
If current detonator supports are designed with multiple components for secure attachment, then attachment reliability is improved, but ease of operation deteriorates
Solution Approach 1:
By merging the latching mechanism, cord engagement features, and housing into a single integrated unit, the device reduces the number of steps required for operation. The operator simply needs to insert the detonation cord and activate the latching mechanism, eliminating the complexity of assembling and coordinating multiple separate components
3Ease of operation
If detonator support is made compact and lightweight, then ease of operation is improved, but attachment security may deteriorate
Solution Approach 1:
The device applies local quality by concentrating structural strength and security features at specific critical locations rather than uniformly throughout the entire structure. The latching mechanism and cord clamping surfaces are reinforced at precise positions where engagement occurs, while other portions of the housing remain lightweight and compact, maintaining both ease of operation and attachment security
4Productivity
If detonator support is designed for quick assembly, then productivity is improved, but manufacturing precision may deteriorate
Solution Approach 1:
The detonator support device is designed with preliminary action features where critical alignment and engagement surfaces are pre-configured during manufacturing. The latching mechanism and cord clamping surfaces are positioned with precision during assembly, allowing the device to be quickly assembled in the field without requiring complex alignment procedures, thus achieving both high productivity and manufacturing precision
