Solution Overview

Problem

In developing countries or remote areas, there is a need for an affordable and easy-to-use method to access electrical energy, as existing solutions often rely on costly and environmentally unsound fossil fuel-based gensets or direct fuel combustion for illumination and other functionalities.

Innovation Solution

A modular functional electrical device comprising an energy storage module and a function-providing module, where the modules are connected through a twist-lock mechanism with spring-loaded connectors and protrusions, allowing easy attachment and detachment, and rotational movement to switch between functional states without dedicated switches, facilitating the use of electrical energy for various functions like lighting, sound, or mechanical energy conversion.

Solution Approach 1:

The patent combines mechanical connection (twist-lock mechanism with protrusion and recess) and electrical connection (spring-loaded connector pins) into a single integrated connection interface. This merging allows both mechanical locking and electrical contact to be achieved through one attachment action, improving ease of operation while managing complexity through functional integration.

Inventive Principle:

Solution Approach 2:

The connection interface serves multiple functions simultaneously: mechanical locking through the twist-lock mechanism, electrical connection through spring-loaded pins, and rotational switching between functional states. This multi-functionality reduces the need for separate components for each function, addressing the complexity concern while maintaining operational simplicity.

Inventive Principle:
