Air Cooling Blower Mounting Flange Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cooling blowers for air-cooled clothing are difficult to mount and dismount, requiring simultaneous insertion and engagement of the mounting ring and lock portions, which reduces work efficiency, especially for those not familiar with the process.
Innovation Solution
The air cooling blower design includes a tubular fan case with an air intake port on one end and an air outlet port on the other, featuring a mounting flange with inclined first and second lock portions and corresponding engagement portions on the mounting ring, allowing for easier mounting and dismounting by displacing the lock portions in the longitudinal direction, facilitating a more user-friendly engagement process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mounting ring and lock portions are designed to engage simultaneously, then the connection is secure, but the mounting and dismounting process becomes complex and difficult for users
Solution Approach 1:
The engagement mechanism is divided into two independent stages: first engagement portion engages with first lock portion, then second engagement portion engages with second lock portion. This segmentation allows users to complete mounting step-by-step without needing to coordinate multiple simultaneous actions, resolving the contradiction between secure connection and ease of operation.
Solution Approach 2:
The first engagement portion is designed to engage with the first lock portion before the second engagement portion engages with the second lock portion. This preliminary action establishes a stable intermediate state that guides the user through the complete mounting process, making the overall operation simpler while maintaining secure connection.
2Device complexity
If the lock portions are positioned at the same location, then the structure is simple, but the mounting process requires precise coordination and is not user-friendly
Solution Approach 1:
The lock portions are arranged at different positions along the longitudinal direction of the tubular fan case, transforming a one-dimensional positioning problem into a multi-dimensional engagement sequence. This spatial arrangement guides users through a natural mounting sequence without requiring precise coordination, improving user-friendliness while maintaining structural simplicity.
3Ease of operation
If the air cooling blower size is reduced, then it is easier to handle and wear, but the air flow capacity may be compromised
Solution Approach 1:
The patent optimizes the internal geometry parameters of the tubular fan case, including the arrangement of lock portions and engagement portions, to maximize air flow capacity within a compact size. By carefully designing the spatial relationship between components, the patent achieves efficient air flow while maintaining a small, easy-to-handle form factor.
