Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fan brackets with bulges and multiple power supply lines are used, then each fan can be independently powered and fixed, but the space efficiency decreases, device complexity increases, and scalability is limited due to multiple power interfaces required
Solution Approach 1:
Multiple power supply lines and control signals are merged into a single power supply line that transmits both power and control signals. The bracket structure merges multiple functions including mechanical support, electrical connection, and magnetic coupling into a single integrated component, eliminating the need for separate power interfaces for each fan.
Solution Approach 2:
The single power supply line serves multiple functions: providing electrical power to multiple fans simultaneously and transmitting control signals for regulating fan speeds. The bracket structure serves multiple purposes: mechanical support, electrical connection through integrated terminals, and magnetic coupling for secure attachment without bulges.
2Ease of operation
If traditional brackets with bulges are used for fan installation, then fans can be securely fixed, but the space efficiency decreases and the bracket design becomes more complex
Solution Approach 1:
The traditional mechanical fastening system with bulges and screws is replaced by a magnetic coupling system. Magnets embedded in the bracket provide secure attachment through magnetic attraction, eliminating the need for protruding mechanical fasteners while maintaining strong fixing capability. This allows for easy installation and removal without complex mechanical operations.
3Power
If multiple power supply lines are used for multiple fans, then each fan receives adequate power, but the number of power interfaces increases and scalability is limited
Solution Approach 1:
Multiple power supply lines are merged into a single power supply line that can simultaneously power multiple fans. The line includes multiple conductors that distribute power to different fans, and a control signal line that regulates the speed of each fan individually, reducing the number of power interfaces from multiple separate connections to a single multi-functional connection.
4Ease of operation
If traditional fan brackets are used without magnetic suction, then the structure is simpler, but the splicing and fixation become more complicated and error-prone
Solution Approach 1:
Manual mechanical alignment and fastening operations are replaced by magnetic attraction forces that automatically align and secure the brackets. The magnetic coupling provides self-aligning fixation that is more accurate and less error-prone than manual mechanical assembly, while the added magnetic components are minimal and integrated into the bracket structure.

AI summary
A magnetic suction fan includes a fan and a bracket, the bracket is connected below the fan, a power supply male terminal and a power supply female terminal are arranged on a side surface of the bracket, one power supply male terminal is matched with and electrically connected to a power supply female terminal of another bracket, and magnetic suction components I and magnetic suction components II are arranged on two sides of an interior of the bracket. Through the above technical solutions, the splicing and electrical connection between several brackets can be achieved, only one external power interface is needed to supply power to brackets and fans above the brackets. The magnetic suction fan not only has less power interface requirements, but also the bracket has no bulges, when used alone, it can not cause insufficient space because of the bulges.
