Dispensing Device Trigger Mechanism for Ergonomic Low-Location Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dispensing devices require users to bend over, kneel down, or contort their bodies to apply flowable materials to low locations, leading to discomfort and potential back strain, as the trigger mechanism is typically positioned beneath the cylinder, making it difficult to access and apply materials to areas like where a floor meets a wall without straining.
Innovation Solution
A dispensing device with a trigger mechanism oriented to allow the user to hold it like a suitcase, positioning the trigger above the cylinder and extending it from the device, enabling users to remain standing while dispensing to low areas, reducing the need for bending or kneeling and minimizing strain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the trigger mechanism is located beneath the cylinder as in conventional dispensing devices, then the device structure is compact and simple, but the user must bend over, kneel down, or squat to access the trigger, causing back strain and discomfort when dispensing to low locations
Solution Approach 1:
The trigger mechanism is repositioned from a horizontal arrangement (beneath the cylinder) to a vertical arrangement (above the cylinder), changing the spatial dimension of operation. This allows the user to operate the trigger while standing upright, eliminating the need to bend or kneel, thus resolving the contradiction between ease of operation and device complexity by introducing a vertical dimension to the trigger-cylinder arrangement
2Ease of operation
If the trigger mechanism is positioned close to the dispensing point for compactness, then the device is more compact, but the user cannot maintain an upright position and must contort body parts to reach low locations
Solution Approach 1:
The handle and trigger mechanism are extended vertically above the cylinder rather than being positioned horizontally near the dispensing point. This vertical extension allows the user to operate the trigger from a comfortable distance while maintaining an upright posture, resolving the contradiction between ease of operation and device length by utilizing the vertical dimension
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
Enables comfortable and safe dispensing of flowable materials to low locations without straining the back, ensuring proper application and reducing the risk of injury by allowing users to maintain an upright position during use.
Implementation Method 1
Upon actuation, a trigger mechanism supplies a pressure medium within the cylinder for displacing the piston in the forward ejecting direction to dispense flowable material from the dispensing device

AI summary
A device for dispensing flowable materials to low locations without the user being required to bend over or kneel down during dispensing provides relief from back strain or other injuries. The device includes a cylinder having a piston mounted therein which reciprocates between forward ejecting and return directions. A driven rod, connected to the piston, extends through a front wall of the cylinder. Upon actuation, a trigger mechanism supplies a pressure medium within the cylinder for displacing the piston in the forward ejecting direction to dispense flowable material from the dispensing device. The trigger mechanism is oriented to enable the user to hold the dispensing device like a suitcase and is spaced a sufficient distance from where the flowable material is dispensed to enable a user to remain standing erect while dispensing to low areas such as where a floor and wall meet.
