Adjustable Brush Mounting for Uniform Turfgrass Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing turfgrass mowers struggle to maintain uniform grass blade lengths, affecting aesthetic appeal and consistency in grass interaction with objects.
Innovation Solution
A brush attachment system for turfgrass mowers featuring adjustable and rotatably fixed mounting brackets that secure a brush to the mower, allowing for precise positioning and angle adjustment to uniformly trim grass before cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a brush attachment system is added to the turfgrass mower, then grass brushing uniformity and aesthetic appeal are improved, but device complexity increases
Solution Approach 1:
The attachment system is divided into separate functional components: crossbeam structure, adjustable mounting brackets, brush assembly, and fastening mechanisms. This segmentation allows each component to be optimized independently while maintaining overall system functionality, resolving the contradiction by making the complex system manageable and adjustable.
Solution Approach 2:
The mounting brackets incorporate adjustable height holes and rotational adjustment capabilities, transforming a static attachment into a dynamic system that can be adapted to different grass heights and brush positions. This dynamic adjustment capability ensures uniform grass brushing while maintaining reasonable structural complexity through standardized adjustment mechanisms.
2Measurement precision
If adjustable mounting brackets with multiple holes and slots are used, then brush position adjustment precision is improved, but manufacturing complexity increases
Solution Approach 1:
The mounting brackets feature localized adjustment elements (height holes in vertical direction, slots in horizontal direction) rather than complex adjustments throughout the entire structure. This local quality approach provides precise position control where needed while keeping the overall bracket design simple and manufacturable.
Solution Approach 2:
The adjustment mechanism utilizes two-dimensional positioning (vertical height holes + horizontal slots) to achieve precise brush placement. This dimensional approach simplifies manufacturing compared to three-dimensional complex mechanisms, as each dimension can be adjusted independently through simple hole-slot alignments.
3Adaptability or versatility
If the brush mount is suspended from the crossbeam with adjustment capability, then adaptability to different grass lengths is improved, but device complexity increases
Solution Approach 1:
The crossbeam-mounted bracket system serves multiple functions: structural support, height adjustment, rotational adjustment, and secure fastening. This multi-functionality provides adaptability to different grass lengths without requiring separate adjustment mechanisms for each function, thereby limiting the increase in device complexity.
Solution Approach 2:
The adjustment holes and slots are pre-positioned on the brackets to provide predetermined adjustment positions. This preliminary arrangement of adjustment features allows quick adaptation to different grass lengths without requiring complex real-time adjustment mechanisms during operation.

AI summary
A brush attachment system for a turfgrass mower with a crossbeam, a brush mount, and left and right mounting brackets. The brush mount is suspended from the crossbeam and is configured to support a brush. The left and right mounting brackets are attached to the left and right ends of the crossbeam, respectively. Each of the mounting brackets may have a bracket plate and a clamp. The bracket plate has a clamping surface, and the clamp is configured to butt against the clamping surface of the bracket plate. Slots extend into the bracket plate and slots extend into the clamp. The slots align when the clamp butts against the clamping surface to form holes through the mounting brackets. The brush attachment system is configured to attach to the turfgrass mower by passing two crossbars of the turfgrass mower through the holes of the mounting brackets.
