Elastic Contact Gasket for SSD Case ESD Gap Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing SSD cases face issues with gaps forming between the upper and lower cases due to manufacturing tolerances and thermal interface materials, leading to incomplete contact and insufficient electrostatic discharge (ESD) levels.
Innovation Solution
A conductive contact gasket with elastic properties is inserted between the upper and lower cases, featuring a lower case contact part, an upper case contact part, and a protrusion that ensures stable contact and enhances ESD levels by maintaining consistent contact through a protrusion that engages with the case sidewalls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fastening means such as bolts are used to fasten upper and lower cases, then the cases are fixedly installed, but gaps are generated due to manufacturing tolerance and thermal interface materials overlap
Solution Approach 1:
A contact gasket is introduced as an intermediary component between the upper case and lower case. The gasket fills the gap formed by manufacturing tolerances and thermal interface materials, ensuring stable contact and electrostatic discharge protection without requiring higher manufacturing precision.
2Stability of the object's composition
If a contact gasket is added to fill gaps, then contact stability is improved, but device complexity increases
Solution Approach 1:
The contact gasket is designed as a thin, flexible component with a simple structure that can elastically deform to accommodate gaps. This flexible film approach provides effective gap filling and contact stabilization without adding significant structural complexity to the device.
3Stability of the object's composition
If the gasket is made elastic to accommodate gaps, then contact is maintained, but ESD level may be insufficient if conductive properties are not optimized
Solution Approach 1:
The contact gasket is made from composite material possessing both elastic properties for gap accommodation and conductive properties for electrostatic discharge protection. This composite structure allows the single component to simultaneously provide mechanical compliance and electrical functionality.

AI summary
Disclosed is an SSD case which includes a contact gasket formed of a conductive material having elasticity and provided in a space so as to be brought into contact with an upper case and a lower case. The contact gasket includes a lower case contact part that makes contact with the lower case and an upper case contact part that extends from the lower case contact part and makes contact with the upper case. One of the lower case contact part and the upper case contact part is fixedly fastened to the lower case or the upper case in contact therewith, and a contact protrusion that protrudes toward the lower case or the upper case such that an end is brought into contact with the lower case or the upper case is formed on the other one of the lower case contact part and the upper case contact part.
