Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling fans experience wear and tear, instability, and safety issues due to continuous vibration and elastic fatigue in their mounting structures, leading to potential user danger.
Innovation Solution
A motor and blade mounting structure featuring a bracket with positioning and locking holes, and the use of elastic washers and a fixing member to securely attach blades, reducing wear and enhancing safety and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional locking structures and protruding posts are used for blade mounting, then assembly is simplified, but wear and tear occurs during continuous operation leading to instability
Solution Approach 1:
The patent introduces elastic washers as a cushioning element between the protruding post and the bracket. This elastic washer absorbs vibration and reduces wear during continuous operation, preventing the wear and tear that leads to blade instability while maintaining the simplicity of the locking structure assembly
2Ease of operation
If elastic holding members are used to hold protruding posts, then assembly is easier, but elastic fatigue causes loss of holding function over time
Solution Approach 1:
The elastic washer is positioned beforehand between the protruding post and the bracket to provide continuous vibration absorption and stress distribution. This prevents elastic fatigue by reducing the stress cycles on the holding members, thereby maintaining the holding function over extended operational periods
Solution Approach 2:
The elastic washer acts as an intermediary element between the rigid protruding post and the bracket. It mediates the mechanical stress and vibration, reducing the direct impact on the elastic holding members and preventing their premature failure due to fatigue
3Ease of manufacture
If simple locking structures are used for blade attachment, then manufacturing cost is reduced, but continuous vibration causes wear and tear
Solution Approach 1:
The elastic washer is integrated into the simple locking structure as a cushioning element that absorbs vibration before it can cause wear and tear on the locking structures and protruding posts. This maintains manufacturing simplicity while protecting against vibration-induced damage
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 solution enhances assembly convenience, safety, and structural support by reducing wear on the bracket and locking structures, while maintaining the holding function of the elastic washers, thereby improving the overall durability and stability of the ceiling fan.
Implementation Method 1
the elastic washers are more likely to lose its holding function because of elastic fatigue
