Traveling Vehicle Battery Layout for Clear View and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric traveling vehicles, particularly racing karts, face issues with reduced field of view and stability due to the placement of batteries on the sides of the seat, which are affected by relative wind and can block the user's view and disturb vehicle travel.
Innovation Solution
The vehicle design incorporates a battery housing portion that inclines such that it overlaps the seat in a side view, with the rear end positioned higher than the front end, and is located further rearward, reducing wind drag and enhancing stability by lowering the center of gravity and applying load to the rear wheels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the battery is mounted on the side of the seat, then the field of view is blocked, but the battery can be easily accessed
Solution Approach 1:
The battery housing is positioned in the rear portion of the vehicle body, utilizing the depth dimension rather than lateral space. This relocates the battery from a lateral position that blocks the side view to a rear position that does not obstruct the user's forward and side visibility, while remaining accessible through the rear of the vehicle
2Ease of operation
If the battery is mounted on the side of the seat, then the battery can be easily accessed, but the traveling stability deteriorates due to wind influence
Solution Approach 1:
The battery housing is extracted from the lateral position beside the seat and relocated to the rear portion of the vehicle body. This extraction removes the battery from the wind-exposed lateral area, eliminating the destabilizing wind influence while preserving accessibility through the rear access design
3Duration of action of moving object
If a large-sized battery is mounted to drive the vehicle for a long time, then the operating duration is extended, but the field of view is blocked
Solution Approach 1:
The battery housing utilizes the rear depth dimension of the vehicle body, allowing a large-sized battery to be accommodated without extending laterally to block the field of view. The battery is positioned in the rear portion, utilizing space that does not interfere with the user's lateral and forward visibility
4Ease of operation
If the battery housing portion is positioned laterally, then the battery is easily accessed, but the wind drag increases
Solution Approach 1:
The battery housing is extracted from the lateral position exposed to wind flow and relocated to the rear portion of the vehicle body. This positioning removes the battery housing from the direct wind path, significantly reducing wind drag while accessibility is maintained through rear access

AI summary
A traveling vehicle includes a body having a seat in which a user can sit, and a plurality of wheels provided to the body, the height of a seat surface of the seat being lower than the upper parts of the plurality of wheels. In the body, a battery accommodation section that accommodates a battery is provided to a side of the seat. At least part of the battery accommodation section overlaps the seat in a side view of the body, and the battery accommodation section is tilted such that a rear end part is positioned higher than a front end part.
