Disposable Paint Container with Venting Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging systems for two-component or multi-component products used in painting or spraying are cumbersome, costly, and prone to errors due to individual component handling, storage, and mixing, leading to inefficiencies and material loss.
Innovation Solution
A disposable container with a projecting bottom part and internal groove for improved sealing and stability, equipped with a rotary valve for air control and a translucent design for content visibility, allowing for easy mixing and connection to a spray gun with a filter for efficient liquid transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual components are packaged separately in airtight containers, then product stability and prevention of clumping are improved, but packaging bulkiness and storage complexity increase
Solution Approach 1:
The patent combines multiple component containers into a single integrated packaging unit. The container includes a body for holding first components and an internal tube for holding second components, both sealed together in one package. This merging approach maintains the stability benefits of separate component packaging while eliminating the complexity of handling multiple separate containers.
Solution Approach 2:
The patent implements nesting by placing the internal tube containing second components inside the container body that holds first components. The internal tube is positioned within the body cavity, allowing compact integration of multiple component storage spaces. This nested structure reduces overall packaging bulkiness while maintaining separate airtight environments for each component type.
2Ease of operation
If multiple transfer operations are performed during preparation, then components can be transferred to spray container, but risks of spillage and loss increase
Solution Approach 1:
The patent merges the storage and transfer functions into a single integrated system. The container body and internal tube are both sealed within the same package and can be emptied directly into the spray container simultaneously or sequentially without intermediate transfers. This eliminates multiple handling operations and associated spillage risks.
Solution Approach 2:
The patent prepares components in advance by pre-packaging them in the integrated container system with appropriate sealing. The container is designed to be opened and emptied in a controlled manner, with the internal tube and body both capable of complete emptying. This preliminary preparation reduces the need for multiple transfer operations during actual use.
3Ease of operation
If operator manually doses components during preparation, then mixing can be performed, but dosing accuracy and product effectiveness are compromised
Solution Approach 1:
The patent performs dosing in advance during the manufacturing stage. Components are precisely measured and packaged in predetermined ratios within the container body and internal tube. The packaging is designed to deliver the correct amounts automatically when emptied, eliminating the need for operator dosing and ensuring consistent accuracy.
Solution Approach 2:
The container system is designed to self-regulate the dosing process. The internal tube and body are configured with specific volumes and opening mechanisms that automatically provide the correct component ratios. When the container is emptied into the spray container, the system self-doses without requiring operator measurement or calculation.
4Duration of action of stationary object
If partially emptied containers are stored after mixing, then remaining components can be preserved, but storage cumbersome and air exposure increases
Solution Approach 1:
The patent combines multiple component storage spaces into a single integrated container that can be partially used and then sealed. The container body and internal tube are both accessible and can be emptied at different rates, allowing the container to be sealed after partial use while maintaining separate airtight environments for remaining components. This is more convenient than storing multiple separate partially-empty containers.
Solution Approach 2:
The patent uses sealed membranes and flexible closing elements to preserve remaining components. The container is equipped with closing means that can seal the opening after partial emptying, creating an airtight barrier. The internal tube and body can both be sealed independently or together, preventing air exposure and deterioration of remaining components while maintaining compact storage.
5Productivity
If disposable container is used for spraying, then preparation time is reduced, but container deformation and sealing reliability may increase
Solution Approach 1:
The patent incorporates reinforcement elements and structural design features beforehand to prevent deformation during use. The container body and internal tube are designed with appropriate wall thicknesses and structural support to withstand the pressures and handling associated with disposable use. This pre-engineered robustness maintains sealing reliability despite the single-use nature of the container.
Solution Approach 2:
The patent combines multiple sealing mechanisms within the integrated container structure. The closing means include sealing elements that engage with both the container body and internal tube, creating multiple sealed barriers. This combined sealing approach compensates for the reduced durability of disposable materials, maintaining reliability throughout the container's service life.
