Artificial Turf Opening Tool for Unentangled Fastener Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Driving a U-shaped nail into artificial grass is laborious due to entanglement with the grass, requiring a tool that can expose the bottom of the grass without becoming entangled.
Innovation Solution
An opening tool with a leading end and side portions that separate the grass, allowing a fastener to be inserted without entanglement, featuring a mechanism where the distance between the side portions is greater than the width of the leading end, enabling easy exposure of the grass bottom for fastener insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a U-shaped nail is driven directly into artificial grass, then the fastening function is achieved, but the nail becomes entangled with the artificial grass making the operation laborious
Solution Approach 1:
The opening tool performs preliminary action by separating the artificial grass blades and exposing the bottom surface before the fastener is inserted. This pre-prepared opening allows the fastener to be driven directly into the ground without encountering entanglement with the grass, thereby eliminating the laborious manual grass-removal step and reducing operation time.
2Ease of operation
If the opening tool separates the grass to expose the bottom, then fastener insertion becomes easy, but the tool structure becomes more complex
Solution Approach 1:
The opening tool is segmented into distinct functional components: a leading end portion for initial grass penetration, side portions for separating grass blades, and an opening formation mechanism. This segmentation allows each component to perform its specific function efficiently while maintaining overall structural simplicity. The side portions can be independently positioned to create the opening without requiring complex mechanical systems.
3Productivity
If the distance between side portions is greater than the leading end width, then grass separation effectiveness is improved, but the tool width increases
Solution Approach 1:
The opening tool employs dynamic geometry where the distance between side portions changes during operation. The side portions are configured to diverge or spread apart as the tool is driven into the grass, allowing the distance between them to exceed the leading end width only during the grass-separation phase. This dynamic adjustment enables effective grass separation while maintaining a more compact tool width during storage and transport.

AI summary
An opening device for parting grass of artificial turf and exposing the base of the artificial turf to drive a securing tool into the artificial turf. The opening device comprises: a tip part extending in the longitudinal direction; and first and second side parts connected to the tip part, and has an opening between the first and second side parts for insertion of the securing tool such as a U-shaped nail. The distance between the outer edges of the first and second side parts is greater than the width of the tip part.
