Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded connections with fastening bolts are used at each fastening point, then secure mounting of the fan is achieved, but assembly complexity increases
Solution Approach 1:
The patent replaces the threaded mechanical connection system with a plug-in connection system. Instead of using fastening bolts and threaded holes, the invention uses a plug-in element that is inserted into a receiving structure, eliminating the need for threading operations and significantly simplifying the assembly process while maintaining secure mounting
Solution Approach 2:
The invention extracts and eliminates the complex threaded connection components (fastening bolts, threads) from the assembly system, replacing them with a simplified plug-in mechanism that achieves the same secure mounting function with fewer parts and simpler operations
2Reliability
If rigid fastening connections are used, then secure mounting is achieved, but acoustic insulation deteriorates due to vibration transmission
Solution Approach 1:
The patent incorporates a flexible element into the plug-in connection structure. This flexible component acts as a vibration damper and acoustic insulator, absorbing vibrations from the fan while maintaining the secure mounting function, thus preventing vibration transmission to the housing
Solution Approach 2:
The flexible element in the plug-in connection provides beforehand cushioning against vibrations. By incorporating this damping element into the connection structure, the system is pre-equipped to absorb and reduce vibrations before they can be transmitted to the housing, improving acoustic insulation
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
Significantly reduces assembly complexity while ensuring a secure and durable mounting of the fan, along with improved acoustic insulation through the flexible socket's ability to absorb vibrations.
Implementation Method 1
the fastening socket consists of an elastic material, in particular, a rubber material
Implementation Method 2
the flexible fastening socket enables an improved acoustic insulation factor between the fan and the retaining part. Due to the flexibility of the fastening socket, undesired vibrations of the fan can be better absorbed
