Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fan frame with combined parts and limited part is used, then fan can be fixed on electronic product, but assembly and disassembly are inconvenient and components may crack by improper external force
Solution Approach 1:
The fan frame is divided into a body portion and a driving part that can move relative to each other along tracks. The driving part can be independently operated to push combined parts through holes, enabling convenient assembly and disassembly without manual manipulation of fragile components.
Solution Approach 2:
The elastic assembly automatically pushes the combined parts through the holes when the driving part moves, eliminating the need for manual insertion. The system performs the fastening action itself through the elastic driving mechanism, improving ease of operation while maintaining reliability.
2Ease of manufacture
If elastic pressing part in U shape hook configuration is used, then fastening parts can be positioned, but elastic recovery force generates crack risk and fatigue after long-time use
Solution Approach 1:
The driving part is designed to move dynamically along tracks defined on the body, transitioning between retracted and extended positions. This dynamic mechanism replaces the static elastic hook, providing controlled elastic force application that reduces stress concentration and fatigue risks during repeated assembly cycles.
Solution Approach 2:
The driving part acts as an intermediary between the elastic assembly and the combined parts. It transmits the elastic force in a controlled manner along the tracks, distributing stress more evenly and preventing direct concentration on the elastic pressing part itself, thereby improving durability.
3Adaptability or versatility
If additional holes are made on installation panel for elastic pressing part and fastening parts, then fan frame can be installed, but installation location is limited and fan size is restricted
Solution Approach 1:
The combined parts are designed to interact with existing holes in the installation panel through the driving part's movement along tracks. The same mechanism serves multiple functions: pushing combined parts through holes, securing them in position, and enabling easy release. This universal mechanism works with varied panel configurations without requiring additional holes, improving both adaptability and location flexibility.
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 the convenience and reliability of fan installation, prevents component damage, allows for easy replacement of elastic parts, and provides better heat dissipation by enabling flexible placement and secure fixing of fans on varied installation panels.
Implementation Method 1
The elastic pressing part 21a is a 'U' shape hook, perpendicularly connected to the fan frame 2a, and would generate elastic recovery force when deformed

AI summary
A fan-fixing device for fixing a fan on an installation panel which has a plurality of holes includes a body, a driving part and an elastic assembly. The body has a fixing portion for fixing the fan, at least one track is formed on a side thereof, and at least one first combined part is disposed on an opposite side thereof, wherein the combined part penetrates at least one of the holes. The driving part slidably disposed on the track. The driving part further has at least one second combined part, which penetrates at least another one of the holes. The elastic assembly is arranged between the body and the driving part. As a result, the first combined part and the second combined part can be fixed in the holes via force pushing the driving part, and can be departed from the holes via releasing the force.
