Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric drive motorcycles face challenges in space optimization and cooling due to the placement of battery units and thermal engines, which limits helmet compartment capacity and affects overall vehicle dimensions and autonomy.
Innovation Solution
The power supply unit is positioned below the helmet carrying compartment, with a polyhedral-shaped battery unit and a control unit cooled by exposed fins, and a hybrid system that includes a thermal engine to optimize space and cooling, allowing effective arrangement of components within the shell body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the battery unit is enlarged to increase vehicle autonomy, then the electric charge capacity is improved, but the available space in the shell body is reduced
Solution Approach 1:
The patent transitions from a lateral arrangement of components to a vertical stacked arrangement. The battery unit, helmet compartment, and saddle are arranged in different vertical levels within the shell body, effectively utilizing the vertical dimension to accommodate a larger battery capacity without increasing the lateral footprint of the vehicle.
Solution Approach 2:
The patent implements a nested configuration where the battery unit is positioned below the helmet carrying compartment, which itself is below the saddle. This nested arrangement allows multiple functional components to occupy overlapping horizontal spaces at different vertical levels, maximizing space utilization in the confined shell body.
2Volume of moving object
If the power supply unit is arranged below the saddle, then the space for helmet compartment is improved, but the cooling effectiveness of power components is worsened
Solution Approach 1:
The patent segments the shell body into distinct vertical zones: the upper zone contains the saddle and helmet compartment, while the lower zone houses the power supply unit with battery and thermal engine. This segmentation allows each component to occupy its optimal spatial position while maintaining adequate thermal separation and cooling pathways for power components.
