Multi-Mode Electric Fan Mounting With Integrated Suction and Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clip fans for golf carts are prone to sliding and falling off due to inadequate clamping, especially on bumpy roads, leading to instability and reduced practicability.
Innovation Solution
A suction cup assembly and force-returning binding band are integrated into the clamping mechanism, allowing the fan to be securely mounted on a glass surface or a rod, with the suction cup absorbing shocks and the binding band enhancing clamping force, while anti-slip protrusions improve stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple clamping structure is used, then the device complexity is reduced, but the clamping force and stability are insufficient causing the fan to slide on bumpy roads
Solution Approach 1:
The patent combines multiple clamping mechanisms (upper and lower clamping plates with elastic components) with a suction cup assembly into an integrated base structure. This merging of mechanical clamping and vacuum suction provides redundant fixation methods, ensuring the fan remains stable on bumpy roads while maintaining reasonable device complexity.
Solution Approach 2:
The patent uses silicone pads (upper and lower silicone pads) between the clamping plates and the clamped object. These silicone materials provide both mechanical compliance and enhanced friction, improving clamping stability without significantly increasing structural complexity. The silicone pads conform to surfaces and maintain consistent contact pressure.
2Reliability
If a suction cup assembly is added to absorb shocks, then the stability on glass surfaces is improved, but the device complexity increases
Solution Approach 1:
The suction cup assembly is integrated into the existing clamping base structure rather than being a separate component. The base simultaneously performs mechanical clamping through the elastic plates and vacuum suction through the integrated cup, providing dual-functionality without proportionally increasing complexity. This merging allows the fan to adhere firmly to glass surfaces while maintaining a compact design.
3Strength
If a force-returning binding band is used to enhance clamping force, then the holding strength is improved, but the device complexity increases
Solution Approach 1:
The force-returning binding band is designed to automatically engage and provide clamping force without requiring additional actuators or complex control mechanisms. The elastic nature of the binding band allows it to self-adjust and maintain clamping force, providing enhanced holding strength while minimizing the increase in device complexity through self-service functionality.
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 design ensures the fan remains firmly attached during bumpy rides, enhancing its usability and preventing displacement, with the suction cup absorbing shocks and the binding band providing additional clamping strength.
Implementation Method 1
The fan is adsorbed onto a glass surface by using the suction cup assembly when clamped on a windshield of a golf cart
Implementation Method 2
most of the all-direction stress obtained when the cart is bumpy is absorbed by the suction cup assembly made of soft silicone
Implementation Method 3
the upper clamping plate is elastically connected to the lower clamping plate through the elastic component
Implementation Method 4
when a clamping assembly clamps a rod on a body of the golf cart, the force-returning binding band is used to enhance a clamping force
Implementation Method 5
each of an outer surface of the upper clamping plate and an outer surface of the pressing portion of the lower clamping plate is provided with a plurality of anti-slip protrusions
