Electric Motorcycle Helmet Compartment and Battery Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric drive motorcycles face challenges in accommodating a helmet carrying compartment, control unit, battery unit, and thermal engine within limited space, requiring innovative arrangements for effective cooling and protection while optimizing available space.
Innovation Solution
The motorcycle positions the power supply unit below the helmet carrying compartment, uses a polyhedral-shaped battery unit, and incorporates a swinging rear fork with a supporting arm to surround the control unit, ensuring protection and cooling, and arranges the battery and thermal engine side by side within the shell body, with a cooling fan and ducts for effective cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the helmet carrying compartment is made capacious enough to store helmets properly, then the storage capacity is improved, but the available space in the rear shell body is reduced due to other components needing accommodation
Solution Approach 1:
The patent applies vertical stacking arrangement in the rear shell body, organizing components along the vertical dimension rather than spreading them horizontally. The helmet carrying compartment is positioned in the upper portion, the battery unit in the intermediate portion, and the control unit in the lower portion, effectively utilizing the vertical space to accommodate all components while maintaining adequate helmet storage capacity.
2Reliability
If the control unit is positioned inside the shell body with adequate protection, then the protection level is improved, but the space occupation and positioning complexity increase
Solution Approach 1:
The patent segments the rear shell body into distinct vertical zones: the upper portion for the helmet carrying compartment, the intermediate portion for the battery unit, and the lower portion for the control unit. This segmentation provides a clear, organized positioning strategy that simplifies the arrangement of protected components while ensuring each occupies an appropriate protected space.
3Use of energy by moving object
If the battery unit is enlarged to provide adequate autonomy, then the energy capacity is improved, but the overall vehicle dimensions and space requirements increase
Solution Approach 1:
The patent places the enlarged battery unit in the intermediate portion of the rear shell body, utilizing the vertical dimension to accommodate the increased battery capacity without proportionally increasing the horizontal footprint. This vertical arrangement allows adequate autonomy while controlling overall vehicle dimensions.
4Volume of stationary object
If the thermal engine and battery unit are arranged side by side to maximize space utilization, then the space efficiency is improved, but the cooling requirements and thermal management complexity increase
Solution Approach 1:
The patent arranges the thermal engine and battery unit in the intermediate portion with vertical separation and spatial distribution that allows both side-by-side placement for space efficiency while maintaining adequate spacing and positioning for thermal management. The control unit in the lower portion and helmet compartment in the upper portion create a layered structure that facilitates cooling airflow paths.
