Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices for viscous cannabis concentrates are cumbersome, often requiring two hands to operate, leading to incomplete fluid evacuation, waste, and difficulty in controlling the dispensing amount, while also being prone to leakage and unintentional misuse, especially by children.
Innovation Solution
A one-handed dispensing apparatus with a twisting mechanism to extend a push-button for fluid release, featuring a thermally resistant tip, child-safety locking mechanism, and retractable plunger to prevent waste and ensure safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional two-handed dispensing device is used, then the device can dispense fluid cannabis concentrate, but it requires one hand to hold or stabilize the dispenser while the second hand engages the dispensing mechanism, making it difficult to also hold or use the vaporization system
Solution Approach 1:
The patent combines the functions of holding the dispenser and actuating the dispensing mechanism into a single hand operation. The thumb actuator is positioned on the side of the cartridge body, allowing the user to engage the dispensing mechanism with their thumb while holding the dispenser body with the same hand. This merging of functions resolves the contradiction by enabling one-handed operation without significantly increasing overall device complexity.
Solution Approach 2:
The patent introduces a thumb actuator as an intermediary component that mediates between the user's hand and the plunger mechanism. This intermediary element allows easy one-handed actuation through a simple pushing motion, translating user input into the mechanical action needed to dispense the concentrate without requiring complex mechanisms.
2Loss of substance
If existing dispensing devices are used, then fluid can be dispensed, but they cannot completely evacuate the reservoir, wasting unused fluid that remains trapped inside
Solution Approach 1:
The patent inverts the traditional dispensing approach by using a push-button mechanism that forces fluid out rather than allowing fluid to flow out passively. The plunger is pushed forward to actively discharge remaining fluid from the reservoir, ensuring complete evacuation. This active pushing mechanism, combined with the ability to retract the plunger, allows users to dispense nearly all fluid without waste while maintaining control over the dispensing process.
Solution Approach 2:
The patent employs a dynamic plunger mechanism that can move forward to dispense fluid and retract to prevent leakage or allow for controlled dispensing. This dynamic capability enables the system to adapt to different dispensing needs, ensuring complete evacuation when desired while allowing users to stop dispensing mid-use if needed, thus reducing waste and improving operational flexibility.
3Measurement precision
If a simple dispensing mechanism is used, then ease of operation is improved, but control over the amount of fluid dispensed becomes difficult
Solution Approach 1:
The patent incorporates visual feedback through a translucent or transparent cartridge body that allows users to observe the fluid level and dispensing progress in real-time. This feedback mechanism enables users to control the amount of fluid dispensed with precision, stopping when the desired amount has been dispensed, without requiring complex measurement or control mechanisms.
4Ease of operation
If viscous cannabis concentrate is dispensed using traditional tools, then transfer can be achieved, but the sticky or tacky physical characteristics make transfer cumbersome and difficult
Solution Approach 1:
The patent uses a pressure-based plunger mechanism to force the viscous cannabis concentrate through a narrow opening in the cap. By applying mechanical pressure to the fluid, the system overcomes the sticky and tacky characteristics of the concentrate, enabling smooth and consistent transfer without the need for scraping or manual manipulation. This hydraulic approach ensures reliable and consistent dispensing of viscous materials.
