Fan Mounting Mechanism with Elastic Track for Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional active heat-radiating structures, such as fans, are inconvenient to adjust in height relative to passive heat-radiating parts due to the need for complete disassembly, which complicates the process and occupies more space.
Innovation Solution
An active heat-radiating structure featuring a fan with an outer frame and mounting members, including tracks and guide grooves, and elastic sheets that allow for height adjustment without separating from the passive heat-radiating part, using positioning points and guide blocks to maintain attachment while allowing for easy height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the fan frame body is completely separated from the radiator to adjust height, then the height adjustment is possible, but the operation becomes complex and time-consuming
Solution Approach 1:
The mounting member incorporates a movable elastic sheet that can slide along the track to adjust height, transforming a static connection into a dynamic, adjustable one. This allows the fan to be repositioned vertically without complete disassembly, resolving the contradiction between adjustability and ease of operation.
Solution Approach 2:
The mounting member is divided into separable components: the elastic sheet, guide block, track, and guide groove. This segmentation allows the elastic sheet to move independently along the track for height adjustment while remaining part of the overall mounting structure, enabling easy repositioning without complete separation.
2Adaptability or versatility
If the fan frame body is completely separated from the radiator to adjust height, then the height adjustment is possible, but the space occupied by the fan increases
Solution Approach 1:
The guide block fits within the guide groove, and the elastic sheet moves within the track, creating a nested arrangement. This nesting allows the adjustment mechanism to be compact, minimizing the space required for height adjustment while maintaining full adjustability.
3Reliability
If conventional mounting methods are used to secure the fan, then the attachment is secure, but the height adjustment requires complete disassembly
Solution Approach 1:
The elastic sheet automatically engages with the track and positioning points to secure the fan at the desired height without requiring additional fastening operations. The guide block within the guide groove provides automatic alignment and constraint, making the mounting process self-servicing and reducing complexity.
Solution Approach 2:
The system uses the position of the elastic sheet along the track as a variable parameter to control height. By changing the position parameter (sliding the elastic sheet to different locations on the track), the fan height is adjusted while maintaining secure attachment through the same mounting mechanism.
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
Enables quick and simple height adjustment of the fan relative to the passive heat-radiating part, reducing operational complexity and space usage, while maintaining secure attachment, facilitating the mounting of additional electronic components without interference.
Implementation Method 1
each of the first mounting portions comprises at least one elastic sheet which can be stressed to move on the track and limited by one of the positioning points
Implementation Method 2
a guide block which can be stressed to slide in the guide groove

AI summary
An active heat-radiating structure attached to a passive heat-radiating part comprises a fan, an outer frame, and two mounting members. The outer frame comprises two first connecting portions arranged at two opposite sides of the outer frame, the two mounting members are disposed on the passive heat-radiating part and connected with the outer frame. Each mounting member is provided with a first mounting portion connected with one first connecting portion. Further, each first connecting portion comprises a track provided with a plurality of positioning points and a guide groove disposed in parallel with the track, and each first mounting portion comprises at least one elastic sheet stressed to move on the track and limited by the positioning point, and a guide block stressed to slide in the guide groove. The position of the fan is adjusted by the two first connecting portions and the two first mounting portions.
