Industrial Truck Battery Receiving Space Tilting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial trucks with electrical travel drives require easy and secure replacement of batteries, which are often heavy and cumbersome, necessitating hoists for conventional batteries but are manageable for smaller lithium-ion batteries, yet require secure holding and easy removal mechanisms.
Innovation Solution
The industrial truck design features a battery receiving space that encloses the energy module, allowing it to be tilted for secure holding and easy removal, with a pivot axis and guide elements ensuring the module is fixed in place and can only be removed after tilting, simplifying the replacement process without additional fastening or hoisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the battery is made heavy with high capacity to operate for a full shift, then the operating duration is improved, but the battery becomes too heavy for manual handling and requires a hoist
Solution Approach 1:
The battery system is segmented into modular energy modules that can be easily replaced. Instead of using one large heavy battery, the system uses interchangeable modules that combine to provide full shift operation, making individual modules lightweight and manageable.
Solution Approach 2:
The battery receiving space is designed with a tilting mechanism that changes its configuration dynamically. During normal operation, the receiving space holds the energy module securely in a horizontal position. During replacement, the receiving space can be tilted to facilitate easy insertion and removal of modules without requiring heavy lifting equipment.
2Reliability
If the battery receiving space fully encloses the energy module, then the module is securely held and cannot be displaced, but the module cannot be easily removed for replacement
Solution Approach 1:
The battery receiving space is designed as a dynamic structure that can change its enclosure state. It features a tilting mechanism with guide elements that provide full enclosure and secure holding during normal operation, but can be tilted to a removal position where the energy module can be easily extracted. The guide elements ensure proper alignment and controlled movement during the tilting process.
3Reliability
If guide elements are added to prevent displacement of the energy module, then the security of holding is improved, but the device complexity increases
Solution Approach 1:
The guide elements are merged with the tilting mechanism of the battery receiving space. The same structural components that enable the receiving space to tilt for easy module removal also serve as guide elements to prevent displacement during normal operation. This integration avoids adding separate complex guiding structures.
Solution Approach 2:
The tilting mechanism serves multiple functions: it facilitates easy removal of the energy module, provides guide elements to prevent displacement during operation, and enables the receiving space to transition between enclosed and open states. This multi-functionality reduces the need for additional specialized components.
