Motorcycle Battery Case Positioning for Splash Protection and Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-wheeled motor vehicles face challenges in protecting the battery from dirt and water splashes while maintaining a sufficient storage space length and minimizing harness length.
Innovation Solution
A two-wheeled motor vehicle design with a battery case positioned below the storage box, ensuring the battery is placed in front of the air cleaner and beside the throttle body, reducing the likelihood of dirt and water exposure and increasing storage space length while minimizing harness length by placing the battery centrally in the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the battery is placed in front of the storage box, then the battery is less likely to get dirt and water splashed by the rear wheel, but the front-rear length of the storage space of the storage box becomes short
Solution Approach 1:
The battery is repositioned from a front-facing arrangement to a side-by-side arrangement with the storage box, utilizing the lateral dimension instead of the front-rear dimension. This allows the battery to be protected from rear wheel splashes while preserving the front-rear length of the storage space for storing items like shoes.
2Object-affected harmful factors
If the battery is placed inside the cover provided around the head pipe and the steering stem, then the battery is less likely to get dirt and water splashed by the rear wheel, but a lengthy harness running between the battery and the engine unit is resulted
Solution Approach 1:
The battery is repositioned from a front-mounted location near the head pipe to a rearward position beside the storage box. This spatial reconfiguration shortens the harness length by reducing the distance between the battery and the engine unit while maintaining protection from rear wheel splashes.
3Object-affected harmful factors
If the battery is placed in front of the air cleaner and beside the throttle body, then the battery is protected from dirt and water splashes and the storage space length is increased, but the harness length may be affected
Solution Approach 1:
The battery is positioned in the lateral space beside the throttle body and air cleaner, utilizing the width dimension rather than extending the front-rear length. This arrangement protects the battery from splashes, maintains storage space length, and positions the battery centrally in the vehicle to minimize harness length.
