Detachable Fan Handle Locking for Compact Portable Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fans have large overall volumes and are inconvenient to carry due to fixed structures, and they offer only basic airflow without customizable functions for diverse user needs.
Innovation Solution
A handheld apparatus with a detachable handle featuring a snap-fit groove and locking mechanism, including a key switch, locking portion, and elastic member, allowing the handle to be easily attached and detached from the fan body, and equipped with a charge/discharge module for additional functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the handle is fixedly connected to the fan body, then the structural stability is improved, but the portability deteriorates
Solution Approach 1:
The handheld apparatus is divided into separate modules: a fan body and a handle that can be detachably connected. This segmentation allows the components to be separated for compact storage while maintaining structural integrity during use through the locking mechanism.
Solution Approach 2:
The connection between the handle and fan body transitions from static (fixed) to dynamic (detachable). The locking mechanism enables the system to switch between a locked state (for stability during operation) and an unlocked state (for portability and compact storage).
2Volume of moving object
If the handle is detachably installed on the fan body, then the portability is improved, but the reliability deteriorates
Solution Approach 1:
The locking mechanism is extracted as a separate functional component that can be independently designed and optimized. This allows the locking feature to be specifically engineered for reliable detachment and reattachment without compromising the overall structural integrity.
Solution Approach 2:
The elastic member pre-stores mechanical energy to ensure reliable locking engagement. When the handle is attached, the elastic member automatically engages the locking portion with the snap-fit groove, providing a cushioning effect that ensures secure connection without requiring additional fastening operations.
