Electric Mower Battery Plate Unit for Stable Multi-Point Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric mowers face challenges in efficiently and accurately mounting large-capacity batteries on their bodies, necessitating improved component mounting solutions.
Innovation Solution
The electric mower incorporates a plate unit comprising multiple plates and brackets that support the battery at multiple positions, allowing stable and accurate mounting, with easy attachment and detachment, while minimizing configuration complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large-capacity battery is installed to improve mowing efficiency, then the battery capacity increases, but the mounting complexity and difficulty increase
Solution Approach 1:
The mounting structure is segmented into multiple plates (first plate, second plate, third plate, fourth plate) that are distributed at different positions. Each plate provides localized support points, dividing the mounting function across multiple simple components rather than requiring a single complex mounting structure. This segmentation allows the large battery to be supported stably while keeping each individual plate simple in design.
2Manufacturing precision
If multiple support points are used to improve battery mounting accuracy, then the mounting accuracy improves, but the number of components increases
Solution Approach 1:
Multiple plates are merged into a single integrated plate unit through the connecting portion of the fourth plate that connects to the first plate. This merging approach provides multiple support points (second plate, third plate, fourth plate) for accurate battery positioning while maintaining structural unity and reducing the number of separate assembly operations required.
3Stability of the object's composition
If a stable battery support structure is implemented, then the battery stability improves, but the attachment and detachment ease decreases
Solution Approach 1:
The plate unit is designed with detachable connections to the body frame, allowing the structure to transition between a stable fixed state during operation and an easily detachable state for maintenance or battery replacement. The connecting portion between the first plate and fourth plate provides structural integrity when assembled while allowing for straightforward disassembly.
