Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paint mixing cups lack effective flow control and sealing mechanisms, leading to paint pollution, waste, and environmental contamination during use, especially when pouring into smaller fluid supply devices.
Innovation Solution
A paint mixing cup with a ring-shaped sealing surface and a flow guiding cover featuring a clamping sealing structure, flow guiding channel, and air pressure balancing hole, ensuring precise control and reduced pollution through dual sealing and smooth paint flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the opening of the paint mixing cup is made large to facilitate pouring, then the ease of operation is improved, but the cup wall and opening are polluted in a large area and paint is wasted
Solution Approach 1:
A flow guiding cover is introduced as an intermediary component between the paint mixing cup and the receiving container. This cover includes a flow guiding channel that directs paint flow along a controlled path, preventing direct contact between paint and the cup's upper edge. The cover acts as a mediator that enables easy pouring while simultaneously preventing pollution and waste.
Solution Approach 2:
The flow guiding channel extends the pouring path in the vertical dimension by guiding paint from the bottom of the cup up through the cover to the outlet. This dimensional extension allows paint to be poured efficiently while keeping the cup's opening area separate from the paint flow path, thus preventing pollution.
2Volume of stationary object
If the caliber of the paint mixing cup is made large to hold more paint, then the volume capacity is improved, but the flow rate is too large when pouring into smaller fluid supply devices, washing them down and causing paint waste
Solution Approach 1:
The flow guiding cover serves as a flow rate control intermediary. Despite the large cup caliber, the cover's flow guiding channel has a controlled cross-sectional area that regulates the paint flow rate. This intermediary component decouples the storage capacity from the pouring rate, allowing large-volume cups to pour at controlled rates suitable for smaller receiving containers.
3Productivity
If the cup cover is equipped with a paint leakage port to enable continuous pouring, then the productivity is improved, but the cup cannot be sealed and toxic substances continuously volatilize polluting the environment
Solution Approach 1:
The flow guiding cover incorporates a movable sealing structure that can dynamically switch between sealed and open states. During storage or non-use, the cover seals completely to prevent toxic volatilization. During use, the cover can be opened to allow pouring. This dynamic capability resolves the contradiction between continuous pouring efficiency and environmental protection.
Solution Approach 2:
The cover is opened periodically only when pouring is needed, and remains closed otherwise. This periodic opening-closing action allows continuous pouring efficiency during work periods while maintaining sealed protection during storage and transport, preventing continuous toxic substance volatilization.

AI summary
Disclosed is a painting mixing cup with guide function, wherein a ring-shaped sealing surface (27) is arranged on an inner surface of an upper edge of the cup body (26), and a clip angle (28) between the ring-shaped sealing surface (27) and a vertical plane is 2°~6°; the cup body (26) is arranged with a guide cover (29), and the guide cover (29) includes a clamping sealing structure (18), and an inner surface of a first ring-shaped plate (20) of the clamping sealing structure (18) cooperates with the ring-shaped sealing surface (27) to form a sealing structure. A reinforcing portion (2) is arranged at the middle part of the guide cover (29) to ensure the cover body (1) does not deform during injection molding and ensure the strength of the guide cover (29), so that the guide channel (3) can obtain the support of the reinforcing portion (2), and the guide channel (3) takes the connection part with the cover body (1) as a fulcrum and the connection part with the reinforcing portion (2) as a pull-back point, thus improving the strength and stability of the guide channel (3) when pouring paint. Meanwhile, the balanced air hole (4) is opened when pouring paint, and the diameter of the guide channel (3) is much smaller than that of the paint mixing cup, so that the user can accurately control the pouring speed of the paint.
