Coupling Shell Design for Leak-Resistant Floor Treatment Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor treatment composition dispensing systems face issues with leakage due to large forces generated during mopping, which can lead to waste and exposure, and the membrane seal is prone to damage during handling and storage, causing instability and leakage.
Innovation Solution
A coupling shell design with a top wall, shell wall, and neck fitment that securely engages with the dispensing package, providing a stable and leak-resistant connection, and protecting the membrane seal by recessing it relative to the top wall, allowing for upright or inverted storage and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the container is engaged with the mop using a simple connection, then the device complexity is reduced, but the connection becomes leaky under large forces
Solution Approach 1:
The connection system is divided into multiple components: a coupling shell that interfaces with the mop, a container with neck fitment, and a membrane seal. This segmentation allows each component to perform its specific function - the coupling shell absorbs mechanical forces, the neck fitment secures the container, and the membrane seal prevents leakage at the interface.
Solution Approach 2:
The membrane seal acts as an intermediary element between the container and the coupling shell. It provides a reliable sealing interface that can withstand large forces generated during mopping operations, preventing leakage without requiring a complex rigid connection structure.
2Device complexity
If the membrane seal is exposed after application, then the dispensing system is simpler, but the seal is prone to unintentional rupture during handling and shipping
Solution Approach 1:
The membrane seal is positioned and secured within the coupling shell before the container is filled or subjected to handling stresses. The neck fitment is pre-configured to receive and protect the seal, ensuring it is in place and protected prior to any operations that could cause rupture.
Solution Approach 2:
The membrane seal is designed as a flexible thin film that can be integrated into the rigid coupling shell structure. This allows the seal to conform to the interface geometry while being protected by the surrounding shell, preventing unintentional rupture during handling and shipping.
3Ease of operation
If the container neck is narrow for practical handling, then the ease of operation is improved, but the container becomes unstable when stored or displayed in an inverted position
Solution Approach 1:
The coupling shell serves as an intermediary structure that connects the narrow-necked container to the mop handle. It provides a broad base for stable inverted storage and display while maintaining the narrow neck for easy container handling and engagement with the dispensing system.
Solution Approach 2:
The coupling shell extends the functional interface from the narrow neck dimension to a broader dimensional interface with the mop handle. This allows the container to maintain its narrow neck for handling while the coupling shell provides the broad base needed for stable inverted positioning during storage and display.
