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.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a direct coupling between the actuating handle and the conversion device is used, then the device structure is simple, but the energy yield is insufficient and flexibility in energy conversion is limited
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.
Solution Approach 2:
The system transitions from a static direct coupling to a dynamic oscillating coupling through the pendulum member. The pendulum's oscillating movement allows for multiple conversion cycles during a single handle actuation, increasing the total energy yield without proportionally increasing device complexity.
2Device complexity
If the conversion device is directly coupled to the actuating handle, then the coupling is simple, but the flexibility in selecting the conversion device is limited
Solution Approach 1:
The gear mechanism and pendulum member serve as a flexible intermediary stage that can accommodate different conversion device types (electromagnetic generators, piezoelectric transducers, etc.). This intermediary coupling allows the system to adapt to various conversion technologies without requiring a complete redesign of the actuation mechanism.
Solution Approach 2:
The pendulum member and gear mechanism form a universal coupling interface that can work with multiple types of conversion devices. The oscillating movement generated by the handle can drive different conversion technologies, making the system versatile and adaptable to various energy conversion requirements.
3Reliability
If a pre-charged battery is used to supply the electrical load, then the energy supply is reliable, but the device requires additional components and pre-charging
Solution Approach 1:
The system is designed to generate its own electrical energy through the conversion device driven by the user's actuation of the handle. This self-service approach eliminates the need for separate battery components and pre-charging infrastructure, reducing device complexity while maintaining energy supply reliability for the electrical load.
