Pulley-Driven Riding Mower Trimmer Attachment for Angled Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Homeowners and landscapers face the challenge of efficiently trimming vegetation that cannot be reached by a riding lawnmower or zero turn, particularly when the vegetation is at an angle, without the need to stop mowing and switch to a weed trimmer.
Innovation Solution
A non-electric Riding Lawn Mower Lawn Trimmer Attachment that can be efficiently attached to any riding deck, featuring a trimmer with a trimmer guard, extender rod, adjustable angle bar, and a pully system driven by the mower's drive pully, along with a support and hinged connection for angled trimming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate weed trimmer is used to trim vegetation at angles, then trimming capability is improved, but time loss due to stopping and switching equipment increases
Solution Approach 1:
The patent combines the lawn mower and weed trimmer into a single integrated machine. The trimmer assembly is mounted on the mower deck, allowing both mowing and trimming functions to be performed with one equipment piece, eliminating the need to stop and switch between separate tools.
Solution Approach 2:
The riding lawn mower is designed to perform multiple functions: it can both mow grass with the deck and trim vegetation at angles using the attached trimmer assembly. This multi-functionality allows the single machine to handle various landscaping tasks without requiring equipment changes.
2Adaptability or versatility
If a fixed trimmer attachment is used, then device complexity is reduced, but adaptability to various terrain angles decreases
Solution Approach 1:
The trimmer assembly incorporates a hinge connection that allows it to move between a stored position and a deployed trimming position. This dynamic capability enables the trimmer to adapt to various angles and terrain conditions while maintaining a compact configuration during transport.
Solution Approach 2:
The trimmer is designed as a separate, modular assembly that can be independently positioned and adjusted. The trimmer head, extender rod, and support structure are segmented components that work together, allowing flexible positioning without requiring the entire machine structure to be complex.
3Ease of operation
If the trimmer is always in position, then readiness to trim is improved, but ease of operation decreases due to inability to store when not in use
Solution Approach 1:
The hinge connection enables the trimmer assembly to be quickly deployed from a stored position to an active trimming position and vice versa. This dynamic mechanism allows the operator to have the trimmer ready when needed while keeping it compact and out of the way during normal mowing operations.
