Elastic Fastening Structure for Thermal Module Rework
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening devices for thermal modules are not easily reworkable, incur high costs due to the need for different dimensions, and are inconvenient to use, as they require permanent welding that can damage components during separation.
Innovation Solution
A fastening structure featuring a main body with elastic press portions, a fastening portion, and an insertion unit, allowing for stable assembly and easy separation from the thermal module without soldering, providing flexibility and cost savings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the fastening device is welded to the radiating fins to achieve fixed connection, then the connection strength is improved, but the ease of repair deteriorates because the components cannot be separated without causing damage
Solution Approach 1:
The fastening device is divided into two separable parts: a clamp body and a fastening element. The clamp body clamps onto the radiating fins while the fastening element threads into the mainboard, allowing the thermal module to be separated and reattached without damage.
Solution Approach 2:
The fastening device transitions from a static welded connection to a dynamic adjustable connection. The clamp can be tightened or loosened by rotating the fastening element, enabling easy assembly and disassembly while maintaining secure connection during operation.
2Adaptability or versatility
If the fastening device is made in different dimensions to match different design requirements, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The clamp body is designed with a universal clamping structure that can accommodate different radiating fin configurations. The adjustable fastening element allows the same clamp body to be used across multiple design variations, eliminating the need for multiple specialized clamp types.
Solution Approach 2:
Instead of creating different clamp bodies for different designs, the invention allows parameter changes through the fastening element (such as thread length or diameter) while keeping the clamp body structure consistent, reducing overall device complexity.

AI summary
A fastening structure is provided for fastening a thermal module to a mainboard, and includes a main body having at least one elastic press portion, a fastening portion, and an insertion unit. The fastening portion is provided on an end of the main body and the insertion unit is outward extended from another opposite end of the main body. The elastic press portion is provided on the main body and located between the insertion unit and the fastening portion, and a flexible space is defined between the elastic press portion and the main body. With these arrangements, the fastening structure can be quickly assembled to the thermal module without the need of welding and can therefore be conveniently separated therefrom whenever reworking is necessary.
