Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Straw cups on the market are difficult to store, prone to dust pollution, and inconvenient to carry due to the exposed straw.
Innovation Solution
A leak-proof straw cup design with a receiving portion, storage portion, and a first water outlet portion that can be stored and easily accessed, featuring a sealing mechanism to prevent dust contamination and a dual-drinking hole for convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the straw is exposed and arranged in the cup body, then the cup is easy to use, but the straw is likely to be polluted by dust and is difficult to store
Solution Approach 1:
The straw is nested within the cup body through a storage cavity and cover structure. When the cover is closed, the straw is stored inside the cup body, protecting it from dust pollution. When the cover is opened, the straw can be easily accessed and used. This nesting structure resolves the contradiction by providing both protection during storage and ease of access during use.
2Ease of operation
If the straw is exposed and arranged in the cup body, then the cup is easy to use, but the cup is inconvenient to carry
Solution Approach 1:
The straw is nested within the cup body through a storage cavity and cover structure. When the cover is closed, the straw is stored inside the cup body, creating a compact and portable design. When the cover is opened, the straw can be easily accessed and used. This nesting structure resolves the contradiction by providing both protection during storage and ease of access during use.
3Object-affected harmful factors
If a sealing portion is added to seal the receiving portion, then the cleanliness is improved, but the device complexity increases
Solution Approach 1:
The cover structure serves as a sealing portion that nests over the cup body opening. This simple nested design effectively seals the receiving portion to prevent dust contamination while maintaining overall structural simplicity. The cover integrates the sealing function without adding complex mechanisms.
4Ease of operation
If the storage portion is added to store the first water outlet portion, then the ease of storage is improved, but the device complexity increases
Solution Approach 1:
The storage cavity is formed within the cup body itself, creating a nested structure where the straw is stored inside the cup. This integration of the storage function into the existing cup structure provides ease of storage without significantly increasing device complexity. The cover closes over this nested arrangement to secure the straw in place.
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 allows easy storage and reduces dust pollution while ensuring leak-proofness and ease of use, with improved cleanliness and convenience in carrying and drinking.
Implementation Method 1
a first magnet is fixed in the storage portion, a second magnet is fixed in the anti-disengagement portion, and the first magnet and the second magnet are mutually attracted to fix positions of the anti-disengagement portion and the storage portion
