M.2 Heat Dissipating Assembly for Front-Side Main Board Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing heat dissipating assemblies for M.2 expansion cards require complex and inconvenient assembly and disassembly processes, as they need to be installed and removed from the back of the main board, which complicates mass production and maintenance.
Innovation Solution
A heat dissipating assembly with a first heat dissipating member and a double-end screwing member that allows for detachable fixation to the main board, enabling the heat dissipating member to be easily assembled and disassembled from the front, using a design with through holes and nuts for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heat dissipating member is installed from the back of the main board using traditional screwing methods, then the heat dissipating member can be securely fixed between the M.2 expansion card and the main board, but the assembly and disassembly process becomes complex and inconvenient requiring the main board to be turned over
Solution Approach 1:
The patent inverts the traditional assembly approach by enabling front-side access for heat dissipating member installation and removal. The double-end screwing member allows screws to be inserted from the front of the main board, eliminating the need to turn over the main board during assembly or disassembly operations.
Solution Approach 2:
The heat dissipating assembly is segmented into independent components: the heat dissipating member, the double-end screwing member with through holes, and the nut. This segmentation allows the screwing member to be operated independently from the front, separating the fixation function from the main board structure.
2Reliability
If the main board is turned over to lock the heat dissipating member from the back, then proper fixation is achieved, but the production process becomes time-consuming and less efficient
Solution Approach 1:
The patent reverses the assembly sequence to allow front-side access for heat dissipating member installation. This inversion eliminates the need to turn over the main board during assembly, significantly improving production efficiency while maintaining secure fixation.
Solution Approach 2:
The double-end screwing member is pre-designed with through holes that align with both the heat dissipating member and the main board. This preliminary design allows workers to directly insert and tighten screws from the front without additional positioning or board manipulation steps.
3Ease of repair
If the heat dissipating member is disassembled by removing the whole main board from the chassis, then the heat dissipating member can be removed, but the disassembly process becomes cumbersome and inconvenient
Solution Approach 1:
The patent enables rear-component access from the front side of the main board. The double-end screwing member design allows the heat dissipating member to be removed by simply unscrewing from the front, eliminating the need to detach the entire main board from the chassis for maintenance operations.
Solution Approach 2:
The heat dissipating member is extracted as an independently accessible component. The through holes in the double-end screwing member allow removal tools to access and operate on the heat dissipating member from the front, separating its maintenance needs from the main board structure.
4Device complexity
If traditional single-side screwing is used to fix the heat dissipating member, then the structure is simple, but the fixation reliability is insufficient for high-temperature M.2 expansion cards
Solution Approach 1:
The patent merges the functions of two screwing operations into a single double-end screwing member component. This unified structure provides dual fixation points that simultaneously secure the heat dissipating member to both the M.2 expansion card and the main board, enhancing stability while maintaining structural simplicity.
Solution Approach 2:
The fixation system is segmented into multiple functional zones within the double-end screwing member: through holes for screw insertion, nut engagement areas for locking, and pressing surfaces for securing the heat dissipating member. This segmentation provides reliable multi-point fixation.

AI summary
A heat dissipating assembly, adapted to be disposed at an M.2 expansion card and configured onto a main board with the M.2 expansion card, is provided. The heat dissipating assembly includes a first heat dissipating member and a first double-end screwing member. The first heat dissipating member is adapted to be disposed on the main board, located between the main board and the M.2 expansion card, and has at least one first through hole. The first double-end screwing member includes a first thread and a first nut having a first screw hole. The first thread passes through one of the at least one first through hole of the first heat dissipating member and is detachably fixed to the main board. The first nut presses against the first heat dissipating member.
