Backpack Sealant Dispensing System for Single-Handed Ladder Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for applying liquid sealant to exterior weather-resistant barriers require two hands, leading to safety concerns when using ladders, and result in frequent downtime due to the limited length of sealant tubes.
Innovation Solution
A backpack dispensing system that houses multiple sealant tubes and applies pressure automatically, allowing the sealant to converge and be dispensed through a hose and gun, enabling single-handed application and reducing downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a two-handed caulking gun and squeegee are used to apply liquid sealant, then the sealant can be applied to the gap between panels, but the user loses three points of contact required for safe ladder use
Solution Approach 1:
The patent replaces the manual two-handed caulking gun operation with an automated dispensing system that uses a motorized pressing device to apply sealant through a hose and applicator tip, eliminating the need for the user to manually operate the caulking gun while on a ladder
Solution Approach 2:
The patent extracts the sealant storage and dispensing function from the traditional caulking gun into a separate backpack-mounted reservoir system, allowing the user to carry the sealant supply without needing to manually manipulate a caulking gun on the ladder
2Ease of manufacture
If standard sealant tubes are used in the caulking gun, then the tubes are easy to replace, but the amount of sealant runs out after about 24 feet requiring frequent replacement and downtime
Solution Approach 1:
The patent merges multiple standard sealant tubes into a single backpack-mounted reservoir system with a total capacity of 96 feet or more, combining the functionality of multiple tubes into one continuous supply that eliminates frequent replacements
Solution Approach 2:
The patent enables continuous sealant application by providing a large-capacity reservoir that supplies sealant through a hose to the applicator, allowing the user to apply sealant continuously for 96 feet or more without stopping to replace tubes
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system allows for continuous application of liquid sealant without frequent tube replacements, enhancing safety by allowing single-handed operation and reducing labor costs through increased efficiency.
Implementation Method 1
The pressing device simultaneously applies pressure automatically to each of the multiple sealant tubes or cartridges
Data Source
AI summary
A backpack and dispensing system for dispensing a caulking or liquid sealant. The pack or backpack houses multiple sealant tubes or cartridges in a pressing device. The pressing device simultaneously applies pressure automatically to each of the multiple sealant tubes or cartridges, which are held in cylindrical holders or holding tubes, causing sealant from each to converge in a converging funnel or connector, where it then passes through a hose or tube to be applied through an application gun, which may be permanently or removably connected to the hose. The converging funnel or connector may be designed to aid in elongating the liquid sealant for application. The gun, which is controlled by a trigger, may use a special sealant tip, which may be removably attached to the gun.
