Mower Cutting Protection Structure for Safe Edge Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intelligent mowers face safety issues due to the distance between the machine body and the ground, which allows feet to extend below the machine body, necessitating manual maintenance of the lawn edges, and the cutting mechanism cannot reach the outermost side of the working region, reducing user experience.
Innovation Solution
A mower design with a cutting mechanism, side part protection, and bottom protection that includes a grass inlet, allowing the cutting mechanism to approach the outer side of the mower, ensuring safety and efficient cutting of lawn edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the distance between the machine body and the ground is increased to ensure safety, then the safety of people is improved, but the cutting mechanism cannot reach the outermost side of the working region, reducing cutting coverage
Solution Approach 1:
The protection structure is divided into two parts: a side part protection and a bottom protection. The side part protection prevents contact from the side direction, while the bottom protection prevents contact from the lower direction. This segmentation allows the cutting mechanism to be positioned closer to the outer side of the machine body without compromising safety, as each protective part addresses a specific directional risk.
Solution Approach 2:
The invention introduces a bottom protection structure that extends in the vertical direction (height direction) to provide protection from the lower direction. This adds a new dimensional aspect to the protection system, allowing the cutting mechanism to approach the outer side of the machine body while maintaining safety through multi-directional protection.
2Reliability
If the distance between the cutting element and the outside wall of the machine body is increased to ensure safety, then the safety of people is improved, but the cutting mechanism cannot cut the lawn away from the outermost side of the working region, requiring manual maintenance
Solution Approach 1:
The protection structure is segmented into side part protection and bottom protection, allowing the cutting mechanism to be positioned closer to the outer side of the machine body. This segmentation enables the cutting mechanism to reach the outermost side of the working region while maintaining safety through directed protection.
Solution Approach 2:
The bottom protection structure with a grass inlet acts as an intermediary element. The grass inlet allows grass to enter the cutting region while the bottom protection prevents direct access to the cutting mechanism from the lower direction. This intermediary structure enables the cutting mechanism to be positioned closer to the machine body outer side without compromising safety.
3Area of stationary object
If the cutting mechanism is positioned closer to the outer side of the machine body to improve cutting coverage, then the cutting coverage is improved, but the safety of people is compromised due to reduced distance between the cutting element and the machine body
Solution Approach 1:
The protection structure is divided into side part protection and bottom protection, allowing the cutting mechanism to be positioned closer to the outer side of the machine body. Each protective part addresses a specific directional risk, enabling improved cutting coverage while maintaining safety through targeted protection.
Solution Approach 2:
The bottom protection structure is provided with a grass inlet at a specific location to allow grass entry while maintaining protection. This local quality modification enables the cutting mechanism to approach the outer side of the machine body without compromising safety, as the protection is localized and targeted where needed.

AI summary
A mower comprising a cutting mechanism configured to execute a cutting operation; a machine body, wherein the machine body is connected with a side part protection which is located in the side of the cutting mechanism to establish a protection barrier in the side of the cutting mechanism; and a bottom protection, located below the cutting mechanism to establish a protection barrier below the cutting mechanism, wherein the bottom protection is provided with a grass inlet. A human body is prevented from making contact with the cutting mechanism from the side direction of the cutting mechanism, the bottom protection can prevent the human body from making contact with the cutting mechanism from the lower side of the cutting mechanism, and the bottom protection is provided with a grass inlet such that the cutting can be smoothly performed.
