Evaporator Closure System with Two-Handed Safety Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing evaporator devices for volatile substances lack effective safety mechanisms to prevent accidental access by children and pets, and they often require more space for refilling due to extended parts outside the heating area.
Innovation Solution
A child-proof closure system with a two-step manipulation procedure using a movable closure member that requires both hands to open, incorporating flexible arms with teeth and hooks to securely lock and unlock, allowing easy access for adults while preventing children and pets from accessing the volatile substance, and a design that keeps the refill container within the heating area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple closure system is used, then ease of operation is improved, but safety against child access deteriorates
Solution Approach 1:
The closure system changes the operational parameters by requiring a specific two-handed twisting motion with simultaneous finger pressure, transforming a simple single-handed operation into a coordinated two-handed action that adults can perform easily but children cannot
Solution Approach 2:
The patent introduces an intermediary mechanism with flexible arms, teeth, and hooks that mediate between the user's manual operation and the closure function, creating a safety barrier that prevents children from accidentally opening while allowing adults to operate it intentionally
2Ease of operation
If the container extends outside the heating area, then ease of refilling is improved, but device volume increases
Solution Approach 1:
The closure member is designed to be movable rather than fixed, dynamically changing position during the opening operation to first extract the container and then provide access, eliminating the need for permanent external extensions
Solution Approach 2:
The opening operation is segmented into distinct phases: initial container extraction followed by user access, allowing the closure member to perform multiple functions sequentially without requiring extended device volume

AI summary
The present invention refers to an evaporator device for volatile substances provided with a closure system that facilitates the replacement of the refill or container of the volatile substance. The invention provides a safety closure system for the evaporator device, which makes difficult for children to get access to the tablet or container of the volatile substance. A closure member and a container are associated in such a manner that during the opening movement of the closure member, at least part of the container is extracted out of the chamber.
