Electric Motorcycle Battery Layout for Fast Lateral Swapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric motorcycles face challenges with complex and time-consuming battery removal and replacement processes, which limit their operational time and efficiency, especially in sports competitions.
Innovation Solution
The design of an electric motorcycle with a frame that serves as both a structural skeleton and a support for battery casings, allowing for lateral removal and replacement of batteries through a system of structural elements and engagement means, simplifying the process and reducing downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If batteries are positioned in a single casing inside the motorcycle for compactness, then space utilization is improved, but battery removal becomes complex and time-consuming
Solution Approach 1:
The patent divides the battery system into separate individual battery units instead of a single integrated casing. Each battery can be independently removed from the motorcycle, allowing operators to quickly exchange batteries without complex disassembly operations. This segmentation resolves the contradiction by maintaining compact space utilization while enabling rapid battery replacement.
2Stability of the object's composition
If batteries are made integral to the vehicle structure for stability, then structural integrity is improved, but battery replacement requires complete vehicle dismantling
Solution Approach 1:
The patent extracts the batteries from the integral vehicle structure, positioning them in accessible locations within the motorcycle body rather than permanently integrating them into the frame. This allows batteries to be removed and replaced independently without dismantling the vehicle's structural components, thus maintaining structural integrity while greatly improving battery replacement ease.
3Duration of action of moving object
If multiple batteries are used to extend operational time, then energy capacity is improved, but battery replacement complexity increases
Solution Approach 1:
The patent implements separate casings for each battery unit, allowing individual batteries to be independently accessed and replaced. When multiple batteries are used to extend operational time, operators can quickly swap out depleted batteries one by one without complex multi-battery replacement procedures, thus maintaining extended operational capability while reducing replacement complexity.
