Measurable Dispenser with One-Way Valve and Child-Proof Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing methods for liquids, particularly for children, are messy, inaccurate, and pose safety risks due to spillage and potential overdose, especially when dealing with substances like medicines that require precise measurement and child-proof handling.
Innovation Solution
A dispenser system featuring a main vessel with a one-way valve and a removable measurable vessel, combined with a child-proof locking mechanism, allows for precise measurement and controlled dispensing by squeezing or pumping, ensuring the measured amount is securely contained until dispensed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pouring or syringe methods are used to dispense liquid medicine, then measurement can be achieved, but the process becomes messy and inaccurate due to spillage and stickiness
Solution Approach 1:
The system divides the dispensing process into two separate vessels: a storage vessel for the bulk liquid medicine and a measuring vessel for the precise dose. The storage vessel contains a one-way valve that controls liquid flow, while the measuring vessel receives the exact amount needed. This segmentation eliminates the messiness of direct pouring or syringe extraction while maintaining measurement precision.
2Ease of operation
If the bottle is kept close to the child for convenient dispensing, then accessibility is improved, but safety risks increase due to potential knockovers, spilling, or unauthorized ingestion
Solution Approach 1:
The system performs preliminary action by pre-measuring the exact dose in a separate measuring vessel before the child needs it. The storage vessel can be kept safely away from the child, while only the small measuring vessel with the pre-measured dose is brought into the child's vicinity. This eliminates safety risks associated with storing large bottles near children while maintaining ease of administration.
Solution Approach 2:
The system extracts the measured dose from the storage vessel into a separate measuring vessel. This extracted portion can be safely handled and administered without risking the entire storage bottle being knocked over or accessed by the child. The harmful potential is taken out and isolated in a controlled, small-scale vessel.
3Object-affected harmful factors
If a child-proof locking mechanism is added to prevent unauthorized access, then safety is improved, but device complexity increases
Solution Approach 1:
The child-proof mechanism is segmented into simple geometric features: a recess in the storage vessel and a protrusion on the measuring vessel that must align for the vessels to connect. This simple geometric interlocking provides effective child-proof protection without adding complex mechanical locking components, maintaining ease of manufacture and operation.
4Measurement precision
If a one-way valve is used to control liquid flow, then precise dispensing is achieved, but the valve mechanism adds device complexity
Solution Approach 1:
The one-way valve is implemented as a simple, inexpensive component that can be easily manufactured into the measuring vessel. It uses basic geometric features (protrusions and recesses) rather than complex mechanical valve components. This simple valve mechanism provides precise liquid flow control while minimizing device complexity and manufacturing cost.
