Lawnmower Trimmer Mount Layout for Forward-View Edging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lawn mower attachments for string trimmers are not optimally positioned for simultaneous trimming and edging operations, requiring operators to divide their attention between the mower path and the trimmer position, leading to difficulty in accurate positioning and potential safety hazards.
Innovation Solution
A mount assembly that attaches a string trimmer to the front wheel side of a lawn mower, allowing for simultaneous operation and positioning without diverting the operator's forward view, featuring a frame attachment clamp, pivotable linkage, and a grade wheel for height adjustment, along with foot pedal control for speed adjustment and quick connects for easy attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the string trimmer is attached to the middle side or rear of the lawnmower, then the attachment is structurally simple and easy to manufacture, but the operator cannot simultaneously view both the lawnmower direction of travel and the trimmer position, requiring the operator to look down to one side and making accurate positioning difficult
Solution Approach 1:
The patent positions the string trimmer in the front lateral region of the lawnmower, utilizing the front lateral space as a new dimensional arrangement. This positioning allows the operator to view both the lawnmower direction of travel and the trimmer position simultaneously within the operator's forward field of view, eliminating the need to look down to one side while maintaining structural simplicity through direct frame mounting
2Reliability
If the string trimmer is attached to the middle side or rear of the lawnmower, then the mount assembly is simpler to manufacture, but the operator must divide attention between looking ahead at the lawnmower path and looking down at the trimmer position, creating safety hazards
Solution Approach 1:
By repositioning the string trimmer to the front lateral region of the lawnmower, the patent places the trimmer within the operator's forward field of view. This dimensional repositioning allows continuous monitoring of both the lawnmower direction and trimmer position without dividing attention, thereby improving operator safety while maintaining a relatively simple direct-mount structure
3Measurement precision
If the string trimmer is attached to the middle side or rear of the lawnmower, then fewer components are needed in the mount assembly, but accurate positioning of the string trimmer for trimming and edging operations becomes difficult
Solution Approach 1:
The patent incorporates a pivotable linkage mechanism that allows the string trimmer to be dynamically adjusted to various positions. This dynamic positioning capability enables accurate placement of the trimmer for different trimming and edging operations while maintaining operational flexibility, achieved through a manageable number of pivot and linkage components
Solution Approach 2:
Positioning the trimmer at the front lateral region provides better geometric alignment with the cutting path, improving positioning accuracy for edging operations along borders and landscapes while maintaining a relatively simple mount structure
