Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat dissipation systems for electronic components are prone to accidental unlocking due to exposure of the operation member, leading to improper attachment of heat sinks, which affects heat dissipation efficiency.
Innovation Solution
An error-unlocking protection structure for heat dissipation base seats, featuring a cover body that shields locking members when the operation member is in the locking position, preventing accidental uninstallation and ensuring secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation member is exposed to the outer side of the heat sink for easy operation, then the ease of operation is improved, but the reliability deteriorates due to accidental unlocking
Solution Approach 1:
The operation member is segmented into two functional parts: an exposed operation portion for user interaction and a hidden locking portion for secure engagement. This segmentation allows the operation member to provide ease of operation through its exposed portion while maintaining reliability through its hidden locking portion that prevents accidental unlocking.
Solution Approach 2:
A protective cover is introduced as an intermediary component between the operation member and the external environment. This cover shields the critical locking portions of the operation member from accidental contact while allowing intentional operation through a designated interface, thus resolving the contradiction between accessibility and protection.
2Ease of operation
If the locking members are exposed for easy installation and adjustment, then the ease of operation is improved, but the reliability deteriorates due to risk of accidental uninstallation
Solution Approach 1:
The locking mechanism is segmented into accessible installation interfaces and protected locking positions. The locking members are designed to be accessible during the installation phase but automatically transition to a protected state after engagement, separating the installation function from the operational state.
Solution Approach 2:
The protective cover is pre-positioned or automatically deployed after installation to shield the locking members. This preliminary protective action ensures that once the locking members are engaged, they are immediately protected from accidental contact, maintaining both ease of installation and subsequent reliability.

Function Achieved in This Case
The solution effectively prevents accidental unlocking and ensures secure attachment of heat dissipation base seats to electronic components, enhancing heat dissipation efficiency and reliability.
Implementation Method 1
The operation member has a cam section pivotally connected with the protruding end of the connection section. When operating the operation member, the cam section is forced to press the top side of the heat dissipation base seat
Implementation Method 2
The bottom side of the heat dissipation base seat is in contact with the heat generation component. The heat sink is tightly attached to the heat generation electronic component to conduct and dissipate the heat generated by the heat generation electronic component

AI summary
An error-unlocking protection structure for heat dissipation base seat includes a heat dissipation base seat, an operation member and a cover body. The operation member has a cam section pivotally connected with the connection section disposed on the heat dissipation base seat. A linking member is disposed between the cover body and the operation member and respectively connected with the cover body and the cam section. When operating the operation member, the cam section is forced to press the heat dissipation base seat and make the heat dissipation base seat tightly attached to the heat generation component and located thereon. At the same time, the linking member is driven to horizontally move the cover body relative to the heat dissipation base seat, whereby the cover body shields locking members to prevent the heat dissipation base seat from being uninstalled from the heat generation component by error.
