Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paint pots require frequent cleaning, are cumbersome to assemble, and have inefficient paint volume measurement and sealing issues, leading to resource wastage and operational difficulties.
Innovation Solution
A disposable paint pot made of transparent aviation material with a pot lid connector featuring an adapter, positioning blocks, and a pot plug with elastic strips and hooks for easy assembly and sealing, along with forward and reverse scale marks for accurate paint volume measurement, and a three-start screw thread for rapid connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the pot body is made reusable and requires cleaning, then resource utilization is improved, but the operation complexity and time consumption increase due to frequent cleaning requirements
Solution Approach 1:
The patent employs a disposable paint pot body made of inexpensive plastic material that is discarded after a single use. This eliminates the need for cleaning operations entirely, as each new paint job uses a fresh pot. The low cost of the disposable pot body makes this economically viable, resolving the contradiction between resource utilization and operational convenience.
2Reliability
If the joint uses inner cone fit or outer cone fit between pot plug and joint, then sealing effectiveness is improved, but the assembly and disassembly force required becomes extremely strong
Solution Approach 1:
The patent divides the sealing mechanism into multiple independent sealing elements: an inner cone-shaped sealing surface at the feed hole, an outer cone-shaped sealing surface at the joint interface, and O-rings positioned at different locations. This segmentation allows each sealing element to contribute to the overall sealing effectiveness while distributing the mechanical stress, reducing the extreme forces needed for assembly and disassembly compared to a single tight-fit mechanism.
3Ease of manufacture
If unidirectional scale marks are used on the pot body, then manufacturing simplicity is improved, but the paint volume measurement accuracy decreases when the pot is inverted
Solution Approach 1:
The patent implements scale marks with different characteristics for different orientations: upward scale marks for when the pot is held upright and downward scale marks for when the pot is inverted. This asymmetric marking system ensures accurate paint volume measurement in both common usage positions, resolving the contradiction between manufacturing simplicity and measurement precision across different orientations.
4Reliability
If the pot lid connector uses screw thread connection, then connection reliability is improved, but the assembly time and physical effort increase due to multiple turning operations
Solution Approach 1:
The patent incorporates pre-assembled quick-connect interfaces between the spray gun and the adapter, and between the adapter and the pot lid connector. These pre-configured connections eliminate the need for multiple screw turning operations during assembly. The reliable connection is achieved through precision-machined mating surfaces and locking mechanisms that are prepared in advance, significantly reducing assembly time and physical effort while maintaining connection reliability.
