Lawn Mower Robot Cover Assembly With Protruding Support Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lawn mower robots face difficulties in assembling the outer cover and support portion due to the outer cover covering the support portion, making it hard to recognize assembling positions and fasten the carrying handle.
Innovation Solution
A lawn mower robot design featuring a protrusion through the outer cover's opening on the support portion for easy recognition and a plate-type prop portion with fastening holes to facilitate assembly of the handle and support portion, along with fitting protrusions and coupling portions for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the outer cover is used to cover the support portion for protection and aesthetic purposes, then the outer cover provides structural protection and clean appearance, but it becomes difficult to visually recognize assembling positions and fasten the carrying handle
Solution Approach 1:
The support portion is segmented into multiple regions: a covered region protected by the outer cover, and an exposed region where the prop portion and fastening holes are located. This segmentation allows the outer cover to protect most of the support portion while leaving specific areas accessible for assembly operations.
Solution Approach 2:
The prop portion acts as an intermediary element that extends from the covered support portion to the exterior through the opening. It provides a accessible interface (with fastening holes) for attaching the carrying handle, mediating between the protected internal structure and the external assembly requirements.
2Shape
If the outer cover completely covers the support portion, then aesthetic appearance is improved, but assembling positions cannot be visually recognized and assembly becomes difficult
Solution Approach 1:
The outer cover is designed to cover only a portion of the support portion, creating distinct covered and uncovered regions. This partial coverage maintains aesthetic appearance while providing visual access to assembly positions through the opening.
Solution Approach 2:
Different regions of the support portion have different coverage qualities: the main body is covered by the outer cover for aesthetics, while specific local areas (where the prop portion emerges) are intentionally left exposed to provide visual guidance for assembly.
