Work Vehicle Battery Side-Mount Layout for Easy Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrically operated and hybrid work vehicles require cumbersome and labor-intensive processes for battery maintenance, involving the use of cranes or jacks for lifting, due to the large and heavy batteries, which complicates easy attachment and detachment.
Innovation Solution
The design incorporates a battery support section that allows for easy mounting and removal of batteries in a left-right direction, eliminating the need for cranes or jacks by positioning the battery between the front and rear travel devices, proximate to the vehicle's center, and utilizing a cart for efficient battery movement, thus reducing the distance and effort required for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery is positioned in a conventional location (front, back, or under the vehicle), then the battery can be mounted and removed, but heavy lifting equipment (crane or jack) is required, increasing the complexity and labor intensity of battery maintenance
Solution Approach 1:
The patent positions the battery support section at the lateral side of the vehicle body rather than at the front, back, or under the vehicle. This lateral positioning allows the battery to be mounted and removed by simple lateral movement without requiring vertical lifting equipment such as cranes or jacks, thereby reducing equipment complexity while maintaining ease of operation
Solution Approach 2:
The battery support section is extracted from the conventional integrated under-vehicle mounting location and positioned separately at the lateral side of the vehicle body. This extraction allows the battery to be accessed and removed independently without affecting other vehicle components, eliminating the need for heavy lifting equipment
2Productivity
If the battery is positioned at the front or back of the vehicle, then the battery can be mounted and removed, but the movement distance is long, increasing the time and effort required for battery maintenance
Solution Approach 1:
The battery support section is positioned at the lateral side of the vehicle body, changing the mounting location from the longitudinal axis (front or back) to the lateral dimension. This lateral positioning reduces the movement distance for battery maintenance operations, allowing workers to access and remove the battery more quickly, thereby improving productivity and reducing time loss
3Stability of the object's composition
If the battery is positioned centrally between the travel devices, then travel stability is improved, but the battery access for maintenance becomes more difficult
Solution Approach 1:
The battery support section is positioned at the lateral side of the vehicle body, combining the benefits of central longitudinal positioning (for stability) with lateral offset positioning (for accessibility). This lateral dimension adjustment allows the battery to be centrally located for stability while remaining easily accessible from the side for maintenance operations
