Lateral Battery Mounting Layout for Stable Work Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrically operated or hybrid work vehicles require easy attachment and detachment of large and heavy batteries, which is currently cumbersome and labor-intensive, often necessitating the use of cranes or jacks for lifting.
Innovation Solution
The design incorporates a battery support section that allows for easy left-right movement of the battery, eliminating the need for cranes or jacks by enabling the battery to be mounted and removed in a shorter, more accessible direction, with the battery positioned between the front and rear travel devices for improved stability and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery is mounted in the front portion of the work vehicle, then the battery can be easily accessed, but the center of gravity shifts forward affecting vehicle stability
Solution Approach 1:
The patent changes the mounting dimension from front-back to left-right by providing battery support sections at both left and right rear portions of the work vehicle. This allows the battery to be mounted laterally rather than longitudinally, resolving the contradiction between accessibility and stability.
2Use of energy by moving object
If a large and heavy battery is used, then the energy capacity is sufficient, but the battery becomes difficult to attach and detach
Solution Approach 1:
The patent divides the battery support function into separate support sections located at the left and right rear portions of the work vehicle. Each support section can independently hold a battery, allowing workers to access and handle batteries more easily by distributing the support locations rather than having a single centralized mounting point.
3Stability of the object's composition
If the battery support section is located at the rear of the work vehicle, then the center of gravity is optimized, but the battery requires lifting vertically which needs equipment
Solution Approach 1:
The patent provides battery support sections at both left and right rear portions of the work vehicle, enabling lateral mounting and detachment of batteries. This eliminates the need for vertical lifting operations while maintaining rear placement for optimal center of gravity, thereby resolving the contradiction between stability and ease of operation.
4Reliability
If the work vehicle is made larger to accommodate the battery, then the battery can be mounted securely, but the vehicle size increases beyond necessity
Solution Approach 1:
The patent utilizes the existing rear space by dividing it into left and right battery support sections. This segmented approach allows secure battery mounting in the available rear space without increasing the overall vehicle dimensions, resolving the contradiction between mounting security and vehicle size.
