Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power distribution systems for weapon accessories lack a unified, efficient, and adaptable method to provide electrical power to multiple devices mounted on a weapon, often requiring multiple connectors and power sources, which can be cumbersome and prone to moisture ingress.
Innovation Solution
A powered accessory platform with a handguard assembly featuring a flexible circuit and accessory mounting rail, integrated with a power supply connector, allowing for centralized power distribution and remote power supply options, including a flexible circuit substrate and heat shield for protection, enabling seamless attachment and operation of various electrical devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate connectors and power sources are used for each accessory, then each accessory can be independently powered, but the system becomes cumbersome and complex
Solution Approach 1:
The handguard assembly is designed as a universal power distribution platform that can power multiple different accessory devices simultaneously through a single integrated system. The flexible circuit board with multiple electrical contacts provides multi-functionality by accommodating various accessory types (lights, lasers, sensors) through a unified interface, eliminating the need for separate connectors and power sources for each device.
Solution Approach 2:
Multiple power distribution functions are merged into a single handguard assembly. The flexible circuit board integrates multiple electrical pathways and contacts that can simultaneously power different accessories, combining what would traditionally require separate connectors and power sources into one unified structure.
2Reliability
If traditional rigid circuit boards and multiple connectors are used, then electrical connections can be established, but moisture ingress becomes a problem
Solution Approach 1:
A flexible circuit board is used instead of traditional rigid circuit boards and multiple separate connectors. The flexible nature of this thin film circuit allows it to conform to the handguard assembly structure while providing multiple electrical contacts in a sealed, integrated configuration that prevents moisture ingress at connection points.
Solution Approach 2:
Multiple electrical connections that would traditionally require separate rigid connectors are merged into a single flexible circuit board assembly. This integration reduces the number of potential moisture ingress points while maintaining reliable electrical connections to multiple accessories simultaneously.
3Ease of operation
If accessories are mounted without integrated power distribution, then mounting flexibility is achieved, but power supply becomes cumbersome
Solution Approach 1:
The handguard assembly serves multiple functions: it provides mechanical mounting for accessories via the Picatinny rail and simultaneously provides electrical power distribution through the flexible circuit board. This universal platform allows accessories to be mounted and powered through a single integrated system, eliminating cumbersome separate power supply configurations.
Solution Approach 2:
The system enables accessories to draw power automatically through the integrated handguard platform without requiring separate power source configuration. The flexible circuit board provides self-service power distribution to mounted accessories, reducing operational complexity.

AI summary
A powered accessory platform for a weapon includes a handguard assembly having an upper handguard portion and an opposed lower handguard portion. The upper handguard portion and the lower handguard portion cooperate to define a sleeve. The sleeve has a proximal end configured to attach to the weapon and a distal end opposite the proximal end. The sleeve is configured to surround at least a portion of the weapon when the proximal end is attached to the weapon. A flexible circuit within the sleeve includes one or more circuit elements disposed on a flexible circuit substrate. An accessory mounting rail is located on a top portion of the upper handguard portion, the mounting rail having at least one electrical connector thereon. A first accessory mounting pad is mechanically and electrically coupled to the accessory mounting rail. A power supply connector on the sleeve is configured to attach a power supply.
