Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weapon platforms lack an integrated and efficient electrical power distribution system that allows for modular accessory mounting and interchangeable power sources, limiting the versatility and functionality of firearm-mounted accessories.
Innovation Solution
A modular weapon platform with a handguard assembly featuring a power supply system that includes a battery box and flexible circuitry, allowing for interchangeable batteries and accessory devices, such as flashlights and grenade launchers, to be easily attached and powered, with a flexible circuit substrate for electrical connectivity and a removable handgrip for axial positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an integrated electrical power distribution system is implemented in a weapon platform, then the versatility and functionality of firearm-mounted accessories is improved, but the device complexity increases
Solution Approach 1:
The power distribution system is segmented into modular components including a power supply module with interchangeable batteries, a handguard assembly with integrated circuitry, and separate accessory mounting interfaces. This segmentation allows independent replacement and maintenance of components while maintaining overall system functionality.
Solution Approach 2:
The handguard assembly serves multiple functions: it provides structural support, integrates electrical power distribution through conductive rails and connectors, offers accessory mounting capabilities via rail interfaces, and enables interchangeable power sources. This multi-functionality reduces the need for separate dedicated components.
2Ease of operation
If interchangeable power sources are implemented in the weapon platform, then the ease of maintenance and operation is improved, but the device complexity increases
Solution Approach 1:
The power supply system is designed with dynamic reconfigurability, allowing the operator to interchange batteries and power sources during operation. The system adapts to different power source configurations through automated detection and routing circuits that adjust electrical connections based on the installed power source type.
Solution Approach 2:
The system includes self-diagnostic and self-configuring capabilities where the circuitry automatically detects the installed power source, establishes appropriate electrical connections through the conductive rails, and routes power to connected accessories without requiring manual configuration by the operator.
3Adaptability or versatility
If modular accessory mounting is implemented on the handguard, then the adaptability of the weapon system is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The accessory mounting system is divided into standardized rail segments with defined mechanical interfaces and tolerance zones. Each rail section incorporates alignment features and mounting positions that accommodate various accessory types while maintaining functional precision within acceptable ranges.
Solution Approach 2:
The rail interfaces are designed as universal mounting systems that accommodate multiple accessory types through standardized attachment mechanisms. The conductive rails simultaneously serve as both mechanical mounting structures and electrical power distribution pathways, integrating structural and electrical functions.
