Mobile Power Supply Unit With Pick-Up Coupling for Machine Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile work-performing machines face limitations in operating range and flexibility due to the need for stationary power sources, which restrict movement and require temporary connections to external power supplies, especially in emergency situations.
Innovation Solution
A mobile power supply unit with a housing, pick-up element, and changeover device that allows the unit to be gripped and moved by the work-performing machine, enabling independent operation and quick detachment from stationary power sources, with a modular power source and bracing device for secure transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stationary power source is used to supply electrical energy to the mobile work-performing machine, then the machine can be supplied with power, but the machine's freedom of movement is restricted and the operating range is limited
Solution Approach 1:
The power supply system transitions from a static configuration (stationary power source with fixed connection) to a dynamic configuration (mobile power supply unit that can be moved and repositioned). The mobile power supply unit can be transported to different locations and connected to the work-performing machine as needed, providing both reliable power supply and operational flexibility.
Solution Approach 2:
The mobile power supply unit acts as an intermediary between stationary power sources and the mobile work-performing machine. It can be charged at stationary locations and then moved to provide power in mobile applications, mediating between the fixed infrastructure and mobile operations.
2Adaptability or versatility
If the power supply unit is designed to be mobile and can be moved by the work-performing machine, then the operating radius is increased, but the device complexity increases due to additional components like pick-up elements and bracing devices
Solution Approach 1:
The pick-up element serves multiple functions: it acts as a mechanical interface for the work-performing machine to grip and move the power supply unit, and it also serves as a structural attachment point for the bracing device. This multi-functionality reduces the need for separate components and simplifies the overall structure.
Solution Approach 2:
The bracing device is integrated with the pick-up element and the power supply unit housing, combining the functions of structural support, attachment, and movement facilitation into a unified system rather than separate components.
