Extendable Wand Sprayer with Locking Trigger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing systems lack improvements in user experience and application efficiency, particularly in delivering sustained duration sprays with manual or battery-operated actuation, and often suffer from issues like leakage and inadvertent actuation during shipping.
Innovation Solution
The development of a squeeze sprayer dispenser with an extendable or foldable wand, a trigger sprayer with a wand or nozzle, and a battery-operated dispensing system integrated with a bottle, featuring a rotatable joint for controlling the flow, a secure locking mechanism to prevent actuation during shipping, and a 'boost' button for increased power, along with ergonomic design and refill capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a wand is extended to move the dispensing point away from the user, then the application precision and control are improved, but the device complexity increases
Solution Approach 1:
The dispensing system is divided into separate modular components: a dispensing head, an extendable wand with adjustable length, and a container. This segmentation allows the wand to be extended or collapsed independently, providing application precision without permanently increasing the complexity of the entire device.
Solution Approach 2:
The wand incorporates an extendable mechanism that allows it to dynamically change length between a retracted position (for storage and reduced complexity) and an extended position (for precise application). This dynamic adjustment resolves the contradiction by providing precision only when needed.
2Power
If a battery-powered motor is used to deliver fluid stream, then the dispensing power and sustained duration are improved, but the weight of the device increases
Solution Approach 1:
The patent replaces heavy battery-powered motorized pumping systems with a lighter mechanical trigger mechanism that uses spring-loaded actuators and user-actuated triggers to deliver the fluid stream. This substitution maintains dispensing power while significantly reducing device weight.
Solution Approach 2:
Instead of continuous motor operation, the system uses periodic trigger actuation where the user pulls a trigger to activate a spring-loaded pump mechanism. This periodic mechanical action provides sustained dispensing capability without the continuous power consumption and weight of battery-powered motors.
3Reliability
If a secure locking mechanism is added to prevent inadvertent actuation during shipping, then the reliability is improved, but the device complexity increases
Solution Approach 1:
A shipping lock mechanism is incorporated that can be preliminarily engaged in a locked position during shipping and storage. This preliminary action prevents inadvertent actuation without requiring complex active control systems, simply needing a passive locking feature that can be engaged or disengaged as needed.
4Adaptability or versatility
If the wand is made extendable for better reach, then the adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The extendable wand is constructed from multiple segmented sections that can be telescopically extended or collapsed. Each section is manufactured to standard dimensions, and the segmentation allows for reach adaptability without requiring complex precision manufacturing of a single long component.
Solution Approach 2:
The wand sections are designed to nest within each other when retracted, similar to a telescoping structure. This nesting arrangement provides extended reach capability while maintaining a compact form factor and reducing the manufacturing precision requirements compared to a solid extended wand.
