Problem
Conventional pyrotechnic and explosive control systems require extensive cabling and large connection devices, leading to logistical challenges, errors, and increased costs due to their size and weight, necessitating more efficient and cost-effective electrical interconnection solutions.
Innovation Solution
A compact electrical interconnection device with a circuit board, input and output connectors, and fasteners that directly connects to a firing module without cabling, achieving a weight of less than 200 grams and dimensions of less than 100 mm in length, width, and height, providing a lightweight and efficient connection system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional cabling and large connection devices are used, then electrical interconnection is achieved, but the system size and weight increase significantly
Solution Approach 1:
The patent merges the circuit board, input connector, and output connector into a single integrated interconnection device. This consolidation eliminates the need for separate cabling and multiple discrete connection components, directly reducing overall system weight and complexity while maintaining full electrical interconnection functionality.
Solution Approach 2:
The interconnection device is designed as a multi-functional unit that simultaneously provides structural support, electrical connection interfaces (both input and output), and circuit board integration. This universal design replaces multiple specialized components (cables, connectors, mounting hardware) with a single device that performs all these functions.
2Ease of operation
If extensive cabling and large rails are used, then electrical communication is established, but handling and servicing become difficult and error-prone
Solution Approach 1:
The patent segments the interconnection system into a compact, self-contained device with integrated components rather than a distributed system of multiple cables and connectors. This segmentation into a single manageable unit dramatically improves handling ease and reduces servicing complexity.
Solution Approach 2:
By combining all connection elements (circuit board, input connector, output connector) into one integrated device, the patent eliminates the need to handle and service multiple separate components. This merging directly addresses the handling and servicing difficulties associated with extensive cabling systems.
3Volume of moving object
If conventional connection devices are used, then electrical interconnection is achieved, but the system occupies excessive space
Solution Approach 1:
The patent implements a nested structure where the input connector and output connector are integrated onto the circuit board within a compact footprint. This nesting of components within the circuit board structure minimizes the overall volume of the interconnection device while maintaining all necessary connection functionalities.
Solution Approach 2:
The integration of multiple connection components into a single compact device significantly reduces the volume occupied by the interconnection system compared to conventional distributed cabling and large rails, directly addressing the space occupation issue.
