SSD Case Protrusion and Sealing Label for Tamper Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a solid state drive case that can be easily checked for disassembly and mass-produced using automated processes, while ensuring security features to prevent data extraction and forgery.
Innovation Solution
The solid state drive case design includes a lower cover with a protrusion and an upper cover having a hole and a sealing label attached to the identification region, allowing for secure coupling and easy identification of disassembly, with the sealing label leaving a trace when removed, satisfying security regulations like FIPS 140-2 Level 2.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing label is attached to the entire surface of the cover, then security against unauthorized disassembly is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The sealing label is selectively attached only to the identification region and protrusion area rather than the entire cover surface. This localized approach maintains security functionality while reducing manufacturing complexity, material usage, and cost.
2Reliability
If a protrusion and hole structure is added for security labeling, then detection of unauthorized disassembly is improved, but device complexity increases
Solution Approach 1:
The protrusion structure serves multiple functions: it provides a mechanical coupling feature between covers, creates a distinct identification region for label attachment, and enables security verification. This multi-functionality reduces the need for separate security mechanisms.
Solution Approach 2:
The cover structure is divided into distinct regions (identification region, protrusion area, sealing label zone) that can be independently manufactured and assembled, facilitating automated production while maintaining security features.
3Productivity
If automated manufacturing processes are implemented, then productivity is improved, but manufacturing precision requirements increase
Solution Approach 1:
The protrusion structure is pre-formed during cover manufacturing to create a predetermined identification region. This preliminary action establishes fixed reference points that guide subsequent label attachment, enabling automated processes to achieve required precision without complex positioning systems.

AI summary
A solid state drive case includes a lower cover having a sidewall defining an internal space. The sidewall includes a protrusion disposed on an end portion of the sidewall. An upper cover has a first surface directly contacting the sidewall of the lower cover and a second surface opposite to the first surface. The upper cover has a hole overlapping the protrusion and configured to receive the protrusion. A sealing label is attached to the second surface of the upper cover. The sealing label has an area that is less than an area of an entirety of the second surface of the cover. At least a portion of the sealing label is attached to an end portion of the protrusion.
