Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screw-locking assembly is used, then reliable connection is achieved, but assembly complexity and time increase
Solution Approach 1:
The housing is segmented into a first housing and a second housing that can be separately assembled. The quick release member is divided into multiple sections with distinct functions (abutting block for locking, connecting piece for positioning, conductive portion for electrical connection). This segmentation allows for simplified assembly operations while maintaining connection reliability through dedicated functional elements.
Solution Approach 2:
The quick release mechanism employs dynamic elements including a resilient member that provides automatic locking when the housings are assembled, and a release button that enables quick disassembly by actuating the locking mechanism. This dynamic design allows the assembly to transition between locked and unlocked states without complex tools or procedures.
2Reliability
If wire-based electrical connection is used, then stable power transmission is achieved, but assembly convenience deteriorates
Solution Approach 1:
The electrical connection function is merged with the mechanical connection structure. The conductive member is integrated into the quick release mechanism, with conductive portions that automatically establish electrical contact when the housings are assembled together. This eliminates the need for separate wire routing and connection steps, improving assembly convenience while maintaining reliable electrical connection through the integrated design.
3Productivity
If quick release mechanism is implemented, then assembly time is reduced, but structural complexity increases
Solution Approach 1:
The quick release member is designed as a multi-functional component that simultaneously provides mechanical locking through the abutting block, positioning through the connecting piece, electrical connection through the conductive portion, and release functionality through the release button. This multi-functionality reduces the number of separate components needed, thereby reducing overall structural complexity while maintaining quick release capability and high assembly speed.

AI summary
A quick release cooling fan structure without wires includes a housing, a quick release member, a carrying member, and a conductive member. A motor is fixed and electrically connected to the carrying member, and the carrying member is quickly assembled to the quick release member in a rotate-in manner. An abutting block of the quick release member is engaged with the locking portion of the housing. The connecting piece of the quick release member cooperates with the groove of the housing for quick assembly, the conductive member is disposed in the first through hole, and the conductive end is inserted through the first and second through holes to come into electric contact with the conductive portion, and thus the internal electric connection inside the cooling fan can be achieved without the use of wires, and the assembly and disassembly of the cooling fan can also be achieved.
