Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The electrification of smaller working machines with high performance requirements, such as bulldozers or crawler loaders, is hindered by the high mass of electrical energy storage systems, which affect weight distribution and installation space, leading to tilting moments that negatively impact driving and working behavior.
Innovation Solution
A mobile working machine with a detachable energy storage module mounted stably at the height of its center of gravity, using bearing elements to optimize weight distribution and minimize tilting moments, and incorporating features like thermal insulation, damping elements, and modular design for easy replacement and charging strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If an energy storage module with considerable charging capacity is installed in the working machine, then the electrification capability is improved, but the dead weight increases causing tilting moments that negatively affect driving and working behavior
Solution Approach 1:
The bearing elements are pre-positioned at a raised height on the energy storage module before installation, specifically designed to align with the module's center of gravity. This preliminary arrangement of mounting elements ensures that when the module is installed in the chassis, the weight is automatically distributed optimally, preventing tilting moments before they can affect machine operation.
2Ease of manufacture
If the energy storage module is mounted in a lower position to utilize installation space, then the installation ease is improved, but the tilting moment increases negatively impacting driving behavior
Solution Approach 1:
Instead of mounting the bearing elements at the conventional lower position on the energy storage module, the invention relocates them to a raised position in the vertical dimension. This dimensional change in mounting height allows the bearing elements to align with the center of gravity, thereby eliminating tilting moments while maintaining installation simplicity through the raised-positioned bearing elements.
3Stability of the object's composition
If the bearing elements are arranged at the height of the centre of gravity, then the tilting moment is reduced improving driving behavior, but the device complexity increases due to precise positioning requirements
Solution Approach 1:
The invention applies local quality by specifically positioning the bearing elements at a particular location (raised height corresponding to the center of gravity) on the energy storage module. This localized precision in bearing element placement achieves the beneficial effect of eliminating tilting moments, while the rest of the module structure remains conventional and simple.
