Extendable Barrel Battery Dispenser for Targeted Spraying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery-operated trigger sprayers lack ergonomic design and ease of use for delivering products in targeted areas, particularly in lawn care and pest control applications.
Innovation Solution
A battery-operated dispenser with a motor-driven pumping mechanism, an extendable barrel, and a slider attachment that allows the internal barrel to be extended or retracted, enabling longer reach and improved usability, powered by rechargeable or alkaline batteries within the shell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the barrel is extended to increase reach, then the dispenser can cover larger areas, but the device complexity increases
Solution Approach 1:
The extension barrel is nested within the main barrel, allowing the barrel to extend to increased length while maintaining a compact form when retracted. This nesting mechanism resolves the contradiction by providing extended reach when needed while keeping the device complexity manageable through a space-efficient design.
Solution Approach 2:
The barrel transitions from a static fixed length to a dynamic extendable structure that can adjust between retracted and extended positions. This dynamic capability allows the dispenser to adapt its reach to different application needs while maintaining a compact profile for storage and transport, effectively resolving the length versus complexity contradiction.
2Ease of operation
If the barrel is made extendable to improve ergonomics and reach, then usability is improved, but the device complexity increases
Solution Approach 1:
The extendable barrel provides dynamic adjustability that improves ergonomics and usability by allowing the user to optimize reach for different application scenarios. The ability to extend and retract the barrel on-demand enhances operational flexibility while the patent manages the associated complexity through practical mechanical design.
3Adaptability or versatility
If batteries are contained within the shell, then the device is self-contained and portable, but the weight of the moving object increases
Solution Approach 1:
The batteries are integrated within the shell housing, merging the power source with the dispenser body to create a self-contained portable unit. This combination eliminates the need for external power supplies or hoses, enhancing versatility and portability for field applications despite the added weight from the battery compartment.
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
Enhances the ergonomic delivery of products with easier operation and extended reach, maintaining consistent performance when the barrel is extended or retracted, addressing the need for improved usability and efficiency in product distribution.
Implementation Method 1
The motor may be powered by one or more batteries—such as rechargeable or alkaline batteries—which may be contained within the shell of the dispenser
Implementation Method 2
A pump chamber controlled by the motor may also be fluidly connected to a nozzle from which a product may be dispensed from the dispenser
Data Source
AI summary
A battery-operated dispenser includes a shell with a moveable slider for extending a barrel of the dispenser to allow targeted application of a fluid or product from a container to which the dispenser is attached.
