Disposable Injection Nozzle for Flooring Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for repairing separated flooring materials from subfloors require costly and messy adhesive injection devices with non-adjustable nozzles, necessitating the removal of flooring materials and often requiring replacement or matching materials.
Innovation Solution
An injection nozzle system with a pre-formed hole and tapered body, compatible with different hole sizes, attached to a cartridge for easy adhesive delivery, allowing for in-place repair without the need for specialized equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional adhesive injection devices are used, then flooring material can be repaired, but the devices are costly and messy requiring cleaning
Solution Approach 1:
The patent employs disposable adhesive cartridges that are discarded after use, eliminating the need for expensive, reusable injection devices that require cleaning and maintenance. The cartridge system provides a low-cost, single-use solution that ensures clean adhesive delivery without the mess and cleaning requirements of traditional reusable devices.
Solution Approach 2:
The invention extracts the adhesive storage and delivery function into a separate, self-contained cartridge that can be easily replaced. This separates the expensive reusable injection mechanism from the consumable adhesive supply, allowing users to only invest in the durable injection device while disposing of the messy adhesive containers.
2Reliability
If specialized adhesive injection devices are used, then adhesive can be delivered, but the nozzles are not adjustable to different hole sizes
Solution Approach 1:
The injection device features an adjustable nozzle system that can be dynamically configured to match different hole diameters. The nozzle extends or retracts, and its diameter can be adjusted, allowing the same device to adapt to various floor hole sizes rather than requiring multiple fixed-nozzle devices.
Solution Approach 2:
The injection device is designed as a universal tool that can handle multiple hole sizes through its adjustable nozzle mechanism. A single device performs the function of multiple specialized nozzles, providing versatility across different repair scenarios without sacrificing reliable adhesive delivery.
3Reliability
If flooring material is removed for repair, then adhesive can be reapplied, but the flooring material must be replaced or matched
Solution Approach 1:
The method involves preliminary cleaning of the adhesive surface before reapplication, and the injection system is designed to deliver adhesive precisely into the existing floor cavity without requiring removal of the flooring material. This preliminary preparation allows the original flooring to be retained rather than replaced.
Solution Approach 2:
The injection system is designed to work with the existing floor structure in place. The adhesive cartridge self-adjusts to deliver material through the pre-drilled hole, and the system accommodates the existing floor geometry rather than requiring the floor to be removed for access.

AI summary
The invention is a method and apparatus for repairing a portion of a floor where a flooring material has become separated from a subfloor, the method includes the steps of: determining a separated area of the flooring material; drilling a first injector hole at the separated area to a void between the flooring material and the subfloor; injecting a liquid adhesive into the first injector hole via an injection nozzle to deliver the liquid adhesive into the void of the separated area; and allowing the liquid adhesive to set. The apparatus is the injection nozzle including a body having a first end, a second end and a passageway extending between the first end and the second end, the first end being configured to receive the liquid adhesive into the passageway, and the second end comprises a pre-formed hole configured to deliver the liquid adhesive from the passageway to the void.
