Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soldiers face significant logistical challenges with battery management and reconfiguration of electronic devices during missions, including weight burden, inefficient battery usage, and difficulty in connecting and reconfiguring equipment in tactical situations due to the use of multiple battery types and cable-based power and data transmission systems.
Innovation Solution
A modular pocket system that enables contactless inductive power and data transfer between a tactical garment and electronic devices, allowing for wireless charging, power management, and communication, with the ability to be repositioned on the garment and featuring a primary inductive charging circuit in the pocket and a secondary circuit in the device, using a conductive textile backplane for connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable-based power and data transmission systems are used, then reliable power delivery is achieved, but connector damage and snagging occur in harsh environments
Solution Approach 1:
The patent replaces mechanical cable and connector-based power transmission with an inductive coupling system. The garment contains an inductive power transmitter that wirelessly transfers power to devices through electromagnetic induction, eliminating exposed connectors and cables that are susceptible to environmental damage, snagging, and connection failures during tactical operations.
2Adaptability or versatility
If multiple battery types are carried for different devices, then all devices can be powered, but weight burden increases to 4 kg
Solution Approach 1:
The patent implements a universal inductive power system where the garment contains a central inductive power transmitter that can simultaneously or sequentially power multiple different electronic devices without requiring device-specific batteries or connectors. The system adaptively manages power distribution to various devices (radios, GPS, flashlights, etc.) through wireless inductive coupling, eliminating the need to carry multiple battery types and reducing total weight.
3Reliability
If soldiers replace batteries manually, then fresh power is ensured, but 70% of carried energy is wasted
Solution Approach 1:
The patent incorporates a central power management system that continuously monitors the charge status of multiple devices through inductive communication. The system receives feedback on battery levels and automatically manages power distribution, charging devices when power is available and prioritizing critical devices when power is limited. This eliminates the need for manual battery replacement and ensures that carried energy is fully utilized according to actual device needs rather than being discarded prematurely.
4Productivity
If cable connections are used for quick setup, then devices can be connected rapidly, but connection difficulty increases with gloved hands
Solution Approach 1:
The patent replaces manual cable connection operations with automatic inductive coupling. Devices are simply placed in proximity to the garment's inductive transmitter, and power transfer begins automatically without requiring soldiers to manipulate connectors or cables with gloved hands. The system detects device presence and initiates charging autonomously, dramatically simplifying operation during tactical situations.
5Ease of manufacture
If fixed pocket configurations are used, then manufacturing is simplified, but reconfiguration capability is lost when roles change
Solution Approach 1:
The patent implements a dynamic pocket system where individual pockets can be independently repositioned, removed, or reconfigured on the garment based on changing tactical requirements or soldier roles. The inductive power system is distributed across multiple locations on the garment, allowing pockets to be moved to different positions while maintaining access to power and data connections, enabling rapid adaptation to different mission scenarios without complicating manufacturing.

AI summary
A modular pocket system includes a modularly mountable pocket modularly mountable to a tactical garment. An insert is mounted in the pocket to align and closely inductively couple a primary inductive coil and related primary drive circuits in the insert to a secondary inductive coil and related secondary charging circuits in a portable electronic device mountable into the insert for the inductively coupled transmission of power between the coils so to transmit power to the portable device, where the device has a rechargeable energy storage component electrically connected to the secondary inductive coil and secondary charging circuits.
