Refill Cartridge Locking and Emptying System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refill cartridge systems for nutrients and chemicals in automatic growing cabinets, pools, and aquariums pose risks of spills, skin irritation, and unauthorized access, as they are typically removable before being completely empty and dry, and lack assurance that emptying containers have sufficient space for new cartridges.
Innovation Solution
A locking and emptying system with a lever mechanism, electromagnetic actuator, and control means ensures refill cartridges are locked in until completely empty and dry, with a piercing mechanism for draining contents into an emptying container of sufficient volume, and control integration with the system's electronics to prevent premature removal and ensure space availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If refill cartridges are made removable at any moment with a manually releasable snap-in joint, then ease of operation is improved, but safety deteriorates due to risk of contact with chemicals before complete emptying
Solution Approach 1:
The system performs the preliminary action of completely emptying the cartridge through the piercing mechanism before allowing removal. The control means ensures the cartridge is emptied and dried before the locking mechanism releases, preventing any risk of chemical contact during the removal process.
Solution Approach 2:
The patent replaces the traditional manual snap-in joint mechanism with an automated locking mechanism controlled by an electromagnetic actuator. This substitution eliminates manual intervention in the locking process and ensures the cartridge can only be removed when safely empty, transforming a potentially dangerous manual operation into a controlled automated process.
2Productivity
If refill cartridges can be removed when container has space, then productivity is improved, but reliability deteriorates due to inability to ensure complete emptying and drying
Solution Approach 1:
The control means receives feedback from sensors that monitor the emptying process and determine when the cartridge is completely empty and dry. This feedback mechanism ensures reliable completion of the emptying process before allowing cartridge removal, eliminating uncertainty about whether the cartridge is fully emptied.
Solution Approach 2:
The system performs the preliminary action of complete emptying and drying of the cartridge before allowing removal. The piercing mechanism ensures all contents are drained, and the control means verifies drying is complete, guaranteeing reliability before the next cartridge can be installed.
3Device complexity
If traditional locking mechanisms are used without integration with emptying control, then device complexity is reduced, but safety deteriorates due to inability to prevent premature removal
Solution Approach 1:
The patent merges the locking mechanism with the emptying control system by integrating the electromagnetic actuator with the piercing mechanism. This combination ensures that the locking function and emptying control are unified, preventing premature removal while maintaining manageable complexity through functional integration rather than separate independent systems.
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
The system ensures user safety by preventing contact with residual chemicals until the cartridge is completely empty and dry, and guarantees that empty cartridges are replaced only when the container has enough space, enhancing operational safety and efficiency.
Implementation Method 1
The end of the operating lever is linked to an electromagnetic actuator in the receiving socket. Said electromagnetic actuator can be in different forms, such as an electromagnet or electric motor with transmission.
