Aerosol Trigger Mechanism for Ceiling Texture Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol systems are not effectively designed for dispensing texture material onto ceiling surfaces, particularly for small repairs where a hopper gun is impractical.
Innovation Solution
An aerosol dispensing system comprising a container assembly with a valve assembly and an actuator assembly that includes a trigger member, allowing for manual operation to pivot and move the outlet assembly, thereby opening the valve for controlled dispensing of texture material onto ceiling surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a hopper gun is used to apply texture material, then the application efficiency is improved, but the device becomes impractical for small repairs and ceiling surfaces
Solution Approach 1:
The invention segments the texture application task by providing different dispensing mechanisms for different repair sizes. The aerosol dispenser handles small repairs while a hopper gun can be used for larger areas, allowing each tool to be optimized for its specific purpose without compromising the other.
Solution Approach 2:
The invention addresses the ceiling application problem by orienting the aerosol dispenser vertically with the outlet facing upward. This dimensional change allows the dispenser to be used on ceiling surfaces where traditional horizontal dispensing would be ineffective.
2Ease of operation
If an aerosol dispenser is used for small repairs, then the ease of operation is improved, but the application efficiency and control are insufficient
Solution Approach 1:
The invention incorporates a dynamic trigger mechanism that allows the user to control the valve opening degree by adjusting trigger pressure. This dynamic control enables the user to optimize the dispensing rate according to the specific repair needs, improving both ease of operation and application efficiency.
Solution Approach 2:
The invention changes the operational parameters of the aerosol dispenser by introducing a trigger mechanism that varies the valve opening degree. This allows the dispensing parameters (flow rate, spray pattern) to be adjusted in real-time, transforming a simple on/off dispenser into a controllable application tool.
3Ease of manufacture
If the valve assembly is simplified for aerosol dispensing, then the ease of manufacture is improved, but the control precision and reliability are reduced
Solution Approach 1:
The invention introduces an intermediary trigger mechanism between the user's action and the valve opening. This trigger assembly acts as a mediator that translates user pressure into controlled valve movement, providing mechanical advantage and precise control without requiring a complex valve internal structure.
Solution Approach 2:
The invention replaces a complex electronically controlled valve system with a simple mechanical trigger mechanism. The trigger uses basic mechanical principles (leverage, friction, direct contact) to control the valve, achieving precise control with minimal manufacturing complexity.

AI summary
An aerosol dispensing system has a container assembly, an actuator assembly, and a trigger member. The container assembly has a valve assembly. The actuator assembly has an actuator housing defining a rail portion, a trigger member pivotably attached to the actuator housing, and an outlet assembly defining an outlet opening. The outlet assembly is slidably supported relative to the actuator housing by the rail portion. The trigger member engages the outlet assembly such that application of deliberate manual force on the trigger member causes pivoting movement of the trigger member relative to the actuator housing and such that pivoting movement of the trigger member relative to the actuator housing causes linear movement of the outlet assembly relative to the actuator housing. The outlet assembly engages the valve assembly such that linear movement of the outlet assembly alters the valve assembly from a closed configuration to a fully open configuration.
