Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric motorcycles face inefficiencies in heat dissipation during operation and charging, as conventional methods often rely on air-guided cooling systems that do not effectively manage thermal energy transfer.
Innovation Solution
The implementation of two lateral cooling elements with external cooling fins that directly contact the surrounding air, allowing for enhanced thermal energy dissipation and additional installation space for components like a larger battery, while using a liquid cooler for improved heat management and protection from external influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional air-guided cooling systems are used, then the structure is simple, but heat dissipation efficiency is insufficient
Solution Approach 1:
The cooling elements extend laterally outward from the housing in addition to the longitudinal direction, creating a three-dimensional cooling structure that increases surface area contact with surrounding air. This dimensional expansion allows more effective heat dissipation without requiring complex ducting systems.
Solution Approach 2:
The cooling system is divided into multiple discrete cooling elements (first and second cooling elements) positioned at different locations along the housing. Each cooling element functions independently to dissipate heat from different components, improving overall heat dissipation efficiency while maintaining structural simplicity.
2Area of stationary object
If cooling elements extend laterally outward, then heat dissipation area increases, but device width increases
Solution Approach 1:
The cooling elements are positioned specifically at the front and rear portions of the housing, concentrating the heat dissipation function in localized areas. This allows the cooling surface area to be increased without proportionally increasing the overall width of the motorcycle, as the lateral extensions are confined to specific zones rather than uniformly distributed.
3Strength
If cooling elements are integrated with housing, then structural strength is improved, but thermal conduction efficiency decreases
Solution Approach 1:
The cooling elements are formed as separate components from the housing material, allowing selection of materials optimized for thermal conduction properties. This separation enables the use of high thermal conductivity materials for the cooling elements while the housing can use materials optimized for structural strength and other requirements.
Solution Approach 2:
The cooling elements act as intermediary components between the internal components that generate heat and the surrounding air. They provide a dedicated thermal pathway with optimized thermal conduction properties, mediating the heat transfer process more efficiently than if the housing material directly conducted heat to the air.

AI summary
An electric motorcycle includes a housing for housing an electric motor and/or a transmission. The housing is positioned at the center of the electric motorcycle in a front view. An internal cooling device and/or an electronic component and two cooling elements extend outward from opposite sides of the housing. Exterior cooling ribs are arranged on the cooling elements. The cooling ribs extend in the longitudinal direction of the electric motorcycle, such that the cooling elements and the cooling ribs are directly in contact with the air surrounding the electric motorcycle. The cooling device and/or the electronic component is, at least in portions, housed in and thermally connected to at least one of the cooling elements.
