Electric Vehicle Accessory Box for Compact Battery Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicles face challenges in compactly integrating a battery and accessories while ensuring protection and ease of maintenance, as they often require dispersed placement that compromises vehicle design and accessibility.
Innovation Solution
An electric vehicle design featuring a vehicle body frame with a seat-mounted accessory box that houses the battery and accessories above the rear end of the main frame and under the seat, allowing central placement of the battery and securing it within what would otherwise be dead space, with the seat fixedly attached to prevent external manipulation during normal use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery and accessories are placed in dispersed locations, then accessibility for maintenance is improved, but the vehicle body becomes less compact and structural integrity is compromised
Solution Approach 1:
The patent combines the battery and accessories into a single integrated accessory box located in the rear lower portion of the vehicle body. This merging of previously dispersed components achieves compact vehicle body design while maintaining ease of maintenance through unified access points and structured organization within the box.
Solution Approach 2:
The accessory box is positioned in the rear lower portion of the vehicle body, utilizing vertical and depth dimensions rather than horizontal dispersion. This dimensional repositioning consolidates components into an compact space while preserving accessibility through strategic placement of access points and component arrangement within the box.
2Ease of repair
If the battery is placed in an exposed location, then ease of maintenance is improved, but protection from external forces is reduced
Solution Approach 1:
The battery is nested within the accessory box, which itself is integrated into the vehicle body structure. This nested arrangement provides multiple layers of protection - the battery is shielded by the box structure while maintaining organized access for maintenance, thus protecting from external forces while preserving ease of repair.
Solution Approach 2:
The accessory box is designed with segmented access points and organized compartments that allow maintenance personnel to access the battery and accessories systematically. This segmentation enables easy maintenance through structured access while the overall box structure provides protection from external forces.
3Volume of moving object
If the accessory box is positioned above the rear end of the main frame, then space utilization is improved, but device complexity increases
Solution Approach 1:
The accessory box positioned above the rear end of the main frame serves multiple functions: it houses the battery, stores accessories, maintains vehicle balance, and provides structural integration. This multi-functionality justifies the structural complexity by delivering comprehensive benefits in space utilization and vehicle performance.
