Blade Carrier Height Adjustment for Autonomous Robotic Mowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lawn mowers cause noise, dust, bumps, and physical fatigue during operation, posing risks to operators and reducing mowing efficiency.
Innovation Solution
A robotic mower with a housing, movable upper cover, and cutting assembly that allows for automated mowing operations, featuring a blade carrier lifting assembly and height-adjustment mechanism to optimize cutting height and reduce operator interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional lawn mower is used, then cutting performance is achieved, but operator safety and health are compromised due to noise, dust, bumps, and physical fatigue
Solution Approach 1:
The robotic mower performs mowing operations autonomously without human intervention during operation. The system includes sensors for navigation, a cutting assembly for mowing, and a control system that enables the mower to independently navigate and complete mowing tasks, eliminating operator exposure to harmful working conditions while maintaining productivity
2Ease of operation
If manual operation is required, then control and adjustment are direct, but physical fatigue and accident risk increase
Solution Approach 1:
The robotic mower autonomously navigates and performs mowing operations without requiring operator control during operation. The system includes navigation sensors, a control system, and automated cutting functions that enable independent operation, completely eliminating physical fatigue and accident risk associated with manual handle control
3Productivity
If cutting height is fixed, then structure is simple, but cutting performance is suboptimal for varying lawn conditions
Solution Approach 1:
The blade carrier is designed with adjustable height capability through a lifting assembly that includes a support column, adjustment mechanism, and locking system. This dynamic structure allows the cutting height to be modified according to different lawn conditions while maintaining structural integrity and cutting performance

AI summary
A mower includes: a housing; a cutting mechanism, disposed on the housing. The cutting mechanism includes a cutting blade, a blade carrier, a blade carrier height-adjustment assembly and a prime mover. The blade carrier height adjustment assembly includes at least two blade carrier connectors for connecting the blade carrier and the prime mover, and an adjusting part for adjusting the relative position of the at least two blade carrier connectors.
