Shoe Drying Machine Connecting Structure Using Rotational Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoe drying machines face issues with inconvenient and labor-intensive connection of shoe supports to wind pipes due to interference fits, leading to loose connections and reduced drying efficiency, especially with tall boots.
Innovation Solution
A connecting structure featuring a first connecting part on the shoe support and a second connecting part on the wind pipe, which lock through circumferential displacement, ensuring axial limitation and preventing disengagement, allowing for a firm and efficient connection without interference fits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If interference fit is used to connect shoe support to wind pipe, then connection firmness is improved, but ease of operation deteriorates due to extremely large friction during connection and disconnection
Solution Approach 1:
The connection interface is segmented into a first connecting part on the shoe support and a second connecting part on the wind pipe, allowing the connection to be divided into insertion and locking stages rather than relying on a single interference fit interface
Solution Approach 2:
The first and second connecting parts act as intermediary elements that mediate the connection between shoe support and wind pipe, providing a controlled locking mechanism that reduces friction during operation while maintaining connection firmness
2Device complexity
If interference fit is used to connect shoe support to wind pipe, then connection simplicity is improved, but reliability deteriorates when shoe support is long due to weakened friction
Solution Approach 1:
The connection mechanism transitions from relying solely on radial interference fit to incorporating axial locking through the first and second connecting parts, adding a dimensional aspect to the connection that prevents loosening along the axial direction
Solution Approach 2:
The connecting parts are designed to preemptively counteract the loosening force generated by thermal expansion of the shoe support, preventing the problem before it occurs during the drying process
3Ease of manufacture
If interference fit is used to connect shoe support to wind pipe, then manufacturing simplicity is improved, but productivity deteriorates due to time-consuming connection and disconnection operations
Solution Approach 1:
The connection mechanism incorporates dynamic elements that allow quick insertion and locking actions, enabling users to rapidly connect and disconnect shoe supports without the time-consuming friction resistance of traditional interference fit
