Pumping Container Spring With Coordinated Helical Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pumping-type container springs experience reduced elastic force and increased variance in elastic force direction due to independent deformation of first and second helical parts, leading to unstable button ascension and inconvenient pressing operations.
Innovation Solution
The first and second helical parts of the spring are designed to be elastically deformable in a mutually restricted state, with specific cross-sectional area variations to maintain consistent deformation and elastic force, ensuring stable button ascension and convenient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the first helical part and the second helical part are separated and independently deformed, then the spring structure is simpler to manufacture, but the elastic force is reduced and the button ascension becomes unstable
Solution Approach 1:
The patent connects the first and second helical parts through connection parts (upper and lower connection parts) to form an integrated spring structure. This merging allows the helical parts to deform in a coordinated manner rather than independently, maintaining consistent elastic force direction and magnitude, which ensures stable button ascension while preserving manufacturing simplicity.
2Adaptability or versatility
If the first helical part and the second helical part are independently deformed, then the spring structure allows greater deformation freedom, but the variance in elastic force magnitude and direction increases
Solution Approach 1:
The patent introduces connection parts at specific locations (upper and lower connection parts connecting the helical parts) to create localized constraints. This allows the spring to maintain deformation freedom in necessary areas while ensuring consistent elastic force characteristics at critical points, resolving the conflict between adaptability and precision.
3Reliability
If the helical parts are connected to restrict mutual deformation, then the elastic force consistency is improved, but the device complexity increases
Solution Approach 1:
The patent divides the spring into distinct functional segments (first helical part, second helical part, upper connection part, lower connection part) that are manufactured separately and then assembled. This segmentation allows for simpler manufacturing of individual components while achieving the desired connected structure that ensures elastic force consistency, thereby reducing overall device complexity.
