Waste Container Closure Mechanism for Odor Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste containers with refill cassettes for tubular material suffer from complex and costly closure mechanisms that often fail to prevent odor escape, making them unsuitable for use in living areas due to insufficient odor containment.
Innovation Solution
A waste container design featuring two pivotable closure bodies with a simplified actuation mechanism, utilizing transmission members and return springs to achieve effective closure and reduced manufacturing costs, allowing for easy manual operation and enhanced odor containment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex locking mechanism is used to close the bag portion, then the closure effect is improved, but the manufacturing cost and device complexity increase significantly
Solution Approach 1:
The closure mechanism is divided into two independent pivotable closure bodies (38a, 38b) that can be actuated separately or simultaneously. Each closure body functions as an independent sealing element that can be controlled by its own actuating device, allowing the system to achieve effective closure without requiring a complex integrated locking mechanism.
Solution Approach 2:
Instead of using a complex locking mechanism that actively secures the closure, the invention uses simple pivotable closure bodies that passively close the bag portion through their weight and simple hinge movement. The closure is maintained by the natural positioning of the closure bodies rather than active locking elements.
2Ease of manufacture
If a simple closure mechanism is used, then the manufacturing cost is reduced, but the odor containment capability deteriorates
Solution Approach 1:
The harmful factor of odor escape is addressed by extracting and isolating the bag portion containing the waste through simple but effective closure bodies. The closure bodies (38a, 38b) create a physical barrier that seals the bag opening, preventing odor escape while maintaining a simple and cost-effective design without complex mechanisms.
3Ease of manufacture
If two pivotable closure bodies are used instead of a complex locking mechanism, then the manufacturing cost is reduced, but the reliability of odor prevention may be compromised
Solution Approach 1:
The two pivotable closure bodies (38a, 38b) work together in combination to provide effective odor prevention. When both closure bodies are in the closed position, they create a dual-seal system that reliably prevents odor escape while maintaining simple construction and low manufacturing costs.
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 design significantly reduces manufacturing costs while effectively preventing odor escape, enabling the waste container to be used in heavily frequented areas like kitchens and children's rooms without causing odor pollution.
Implementation Method 1
the actuating device has one or more return springs, wherein a closing movement of the closure body can be implemented by means of the spring load
Implementation Method 2
a linear movement of the actuating unit can be converted into a pivoting movement of the closure body via the one or more transmission elements
