Electric Motorcycle Conversion Kit That Preserves Engine Appearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric conversion kits for motorcycles alter the aesthetic characteristics and mechanical transmission of combustion motorcycles, are difficult to manufacture, and are expensive, failing to meet the needs of enthusiast consumers.
Innovation Solution
A kit that allows for electric conversion by integrating an electric motor and drive shaft within the internal combustion engine, maintaining the motorcycle's aesthetic appearance and preserving the mechanical transmission, using a transmission system to convert rotary motion from the electric motor to the drive shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the internal combustion engine is completely removed and replaced with a new electric motor, then electric conversion is achieved, but the aesthetic characteristics and design of the motorcycle are deeply altered
Solution Approach 1:
The electric motor is nested within the existing engine chamber, with the motor housing containing the electric motor components. This allows the electric powertrain to be housed within the original engine space, maintaining the external aesthetic characteristics while achieving electric conversion
Solution Approach 2:
The kit preserves the original engine's external shape and mounting points, creating a visual copy of the original engine appearance while the internal components are replaced with electric motor components, thus maintaining aesthetic characteristics while achieving electric conversion
2Device complexity
If a direct-drive system on the motorcycle wheel is used, then electric conversion is simplified, but the mechanical gear transmission must be removed or made unusable
Solution Approach 1:
The drive shaft serves multiple functions: it can be directly driven by the electric motor for electric operation, or it can transmit mechanical power from the original engine through the existing gear transmission system. This multi-functional design allows the system to operate in both electric and mechanical modes without requiring removal of the gear transmission
3Shape
If the electric motor is integrated within the existing engine chamber, then aesthetic characteristics are maintained, but the device complexity increases
Solution Approach 1:
The conversion kit is divided into separate modular components including the electric motor, drive shaft, and mounting brackets. This segmentation allows for easier assembly and disassembly, reducing the practical complexity of installation while maintaining the integrated appearance within the engine chamber
