Fan Module Support Structure for Thin Casing Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with thin casings suffer from weak structural strength, leading to deformation under external forces, which interferes with fan rotation, generates noise, and compromises heat dissipation efficiency due to the close gap between the fan and the casing.
Innovation Solution
A fan module comprising a first and second casing, a supporting assembly, a stator assembly, and a rotator assembly, where the supporting assembly protrudes out of both casings to enhance structural support, prevent deformation, and maintain fan rotation direction, while the stator and rotator assemblies facilitate heat dissipation through magnetic interaction and fan blade rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a thin casing is used for portability, then the electronic device becomes more portable, but the casing strength becomes weak and the device is prone to deformation under external force
Solution Approach 1:
The supporting assembly is divided into multiple independent supporting parts that can be distributed at different locations within the casing. Each supporting part provides localized reinforcement, allowing the overall casing to remain thin while gaining structural strength at critical points where the fan module is located.
Solution Approach 2:
The supporting assembly acts as an intermediary structural element between the thin casing and the fan module. It transfers and distributes external forces away from the fan module, preventing the thin casing from deforming under load and interfering with fan operation.
2Volume of stationary object
If the gap between the fan and the casing is small to save space, then the internal space utilization is improved, but the casing deforms under external force and interferes with the fan rotation direction
Solution Approach 1:
The supporting assembly serves as a protective intermediary between the thin casing and the fan module. It absorbs and distributes external forces before they can reach the fan, ensuring that the fan's rotation direction remains stable even when the casing is subjected to external pressure.
Solution Approach 2:
The supporting assembly is pre-positioned within the casing to counteract potential deformation forces before they can affect the fan module. By being in place beforehand, it prevents the casing from deforming in a way that would interfere with fan rotation, rather than correcting deformation after it occurs.
3Length of moving object
If the casing is thin for portability, then the device is more portable, but noise is generated when the deformed casing interferes with the fan rotation
Solution Approach 1:
The supporting assembly acts as a protective intermediary that isolates the fan module from the thin casing's deformation. By absorbing external forces, it prevents the casing from contacting or interfering with the rotating fan blades, thereby eliminating the source of noise generation.
Solution Approach 2:
The supporting assembly converts the potential harm of external forces into a beneficial effect by absorbing and distributing these forces before they can reach the fan module. What would otherwise cause noise and interference is instead used to compress and stabilize the supporting structure, protecting the fan from deformation-induced interference.
4Strength
If the casing deforms under external force, then the structural integrity is compromised, but the heat dissipation efficiency is not easy to be maintained
Solution Approach 1:
The supporting assembly is segmented into multiple supporting parts distributed strategically within the casing. This segmentation allows the structure to maintain overall integrity while providing localized reinforcement at the fan module area, ensuring both structural strength and proper airflow channels for heat dissipation are preserved.
Solution Approach 2:
The supporting assembly serves as a stable intermediary structure that maintains the spatial relationship between the fan module and the casing. By preventing casing deformation, it ensures that airflow channels remain unobstructed and the fan can operate efficiently, thereby maintaining heat dissipation performance even when the device is subjected to external forces.
