Solution Overview

Problem

Existing discharge devices for liquid, pasty, or powdery media struggle with low flexibility in energy conversion due to the type of movement direction and insufficient energy yield from mechanical energy conversion to electrical energy, particularly when coupled directly to the actuating handle.

Innovation Solution

A discharge device that converts the mechanical energy from a linearly movable handle into a non-rotative oscillating movement of a pendulum member, using a gear system, which is then converted into electrical energy using various conversion devices such as electromagnetic generators or piezoelectric transducers, allowing for improved energy generation independent of user actuation speed.

Solution Approach 1:

A pendulum member is introduced as an intermediary between the actuating handle and the conversion device. The linear movement of the handle is converted into oscillating movement of the pendulum member through a gear mechanism, which then drives the conversion device. This intermediary element enables more effective energy conversion while maintaining reasonable structural complexity.
