Pet Bed Artificial Turf Attachment Using Threaded Dowels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet beds lack a durable and effective mechanism to secure artificial turf to an underlying substrate, leading to instability and potential separation over time.
Innovation Solution
A pet bed design featuring a foam core with elongate connectors and retainer bars that secure artificial turf in place, using dowels with threaded ends and fasteners to create a dynamic tension mechanism, ensuring the turf remains firmly attached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If artificial turf is placed on a foam core without a securing mechanism, then the pet bed is simple and easy to manufacture, but the artificial turf becomes unstable and separates from the substrate over time
Solution Approach 1:
The foam core is segmented with multiple elongate connectors distributed throughout its structure. These connectors divide the attachment function into discrete locations, allowing the artificial turf to be secured at multiple points rather than requiring a continuous complex bonding mechanism throughout the entire surface.
Solution Approach 2:
The securing mechanism extends into the third dimension by using elongate connectors that protrude from the foam core surface. This vertical dimension allows the artificial turf to be attached at elevated points above the foam core surface, creating a more reliable mechanical connection without requiring complex planar attachment systems.
2Strength
If elongate connectors with threaded ends and fasteners are used to secure artificial turf, then the attachment becomes durable and stable, but the manufacturing process becomes more complex
Solution Approach 1:
The elongate connectors are pre-formed with threaded ends during the foam core manufacturing process. This preliminary action allows the securing mechanism components to be prepared in advance, so that during final assembly, only the simple operation of inserting connectors and tightening fasteners is required, rather than assembling multiple separate components.
3Stability of the object's composition
If the artificial turf is securely fastened to the foam core, then the pet bed maintains its shape and prevents sagging, but the weight of the bed increases
Solution Approach 1:
The artificial turf itself serves as the securing element, utilizing its own flexible yet durable structure to attach to the foam core. The thin film nature of the turf material allows it to be secured with minimal additional components, maintaining structural integrity without significantly increasing the overall weight of the pet bed.

AI summary
Platform for particular use as a pet bed includes a foam core having an upper surface, a lower surface on an opposite side of the foam core from the upper surfaces, and at least one side surface between the upper and lower surfaces along a periphery of the foam core. Artificial turf extends over the upper surface and alongside each side surface. Elongate connectors extend through the foam core between the upper and lower surfaces and have opposite end regions projecting out of opposite sides of the foam core. These connectors may be rods or dowels with threaded end regions that pass through apertures in flaps of the artificial turf. Fasteners are screwed onto the threaded end regions of the dowels with the artificial turf inward of the fasteners to thereby cause the artificial turf to be urged toward and secured to the foam core.
