Grass Mower Adjustable Height Support Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grass mowers face limitations in achieving various mowing heights due to restrictions on the size of the traveling machine body, requiring multiple frame configurations and increasing manufacturing costs.
Innovation Solution
A grass mower design that allows for adjustable mowing heights by changing the mounting positions of the traveling machine body and the working machine body, utilizing a support member with an upper and lower member, and an insertion support member that can be coupled in different states to achieve two distinct mowing heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple frame configurations are used to achieve various mowing heights, then the adaptability for different mowing height requirements is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The support member enables dynamic reconfiguration of the frame by allowing the insertion support member to be positioned at different locations (between upper and lower members, or on their surfaces), creating variable mounting positions that accommodate different mowing height requirements without requiring multiple fixed frame configurations
Solution Approach 2:
The support member is divided into separate components (upper member, lower member, and insertion support member) that can be independently positioned and coupled, allowing flexible assembly to achieve different mowing heights while maintaining a single base frame configuration
2Adaptability or versatility
If multiple frame configurations are manufactured for different mowing heights, then the adaptability for regional mowing height requirements is improved, but the manufacturing cost increases due to multiple molding molds
Solution Approach 1:
A single frame configuration with the versatile support member system can serve multiple mowing height requirements (e.g., 60mm in Europe, 100mm in America) by repositioning the insertion support member, making one frame design universal across different regions and eliminating the need for region-specific frame variants
Solution Approach 2:
The mowing height parameter is adjusted by changing the mounting position of the working machine body on the support member rather than by manufacturing different frame configurations, allowing the same frame to adapt to different height parameters through reconfiguration
3Ease of operation
If the size of the traveling machine body is restricted, then the ease of operation in confined spaces is improved, but the range of mowing height adjustment is limited
Solution Approach 1:
The system achieves extended mowing height adjustment range through dynamic repositioning of the insertion support member on the support member, allowing the compact traveling machine body to access a wider variety of mowing heights without requiring physical size expansion

AI summary
Each side frame that supports a traveling machine body includes a front insertion support member and a rear insertion support member that can be inserted into a front support member and a rear support member, respectively. The grass mower includes bolts that are couplable selectively in a first state where the front insertion support member and the rear insertion support member are inserted between a front upper member and a rear upper member, and a front lower member and a rear lower member, respectively, and a second state where the front insertion support member and the rear insertion support member are mounted on lower surfaces of the front lower member and the rear lower member, respectively.
