Intrusion Switch Detecting Computer Case Cover Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security measures for computer systems fail to effectively detect and prevent unauthorized access, as they can be tampered with without leaving detectable evidence, posing a risk to sensitive data.
Innovation Solution
A tamper-proof intrusion switch is integrated into the computer system's housing, which detects unauthorized access by monitoring the movement of a removable cover, triggering an alert or indication when the cover is disengaged, and requires physical tampering to deactivate, leaving visible evidence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing security measures are used to detect unauthorized access, then intrusion detection is provided, but the measures can be tampered with without leaving detectable evidence
Solution Approach 1:
The patent employs visual indicators that change state to provide tamper evidence. When the intrusion switch is triggered by unauthorized cover removal, the system provides visible indication through LED lights or other visual signals that change from a normal state to an alarm state, making tampering detectable and reliable intrusion detection possible.
2Ease of operation
If the intrusion switch is made accessible for activation, then ease of operation is improved, but vulnerability to unauthorized tampering increases
Solution Approach 1:
The housing is segmented into a base and a removable cover, with the intrusion switch integrated into the base. The cover includes engagement members that must be properly positioned to activate the switch. This segmentation allows legitimate users to access and activate the switch through the cover mechanism while preventing unauthorized access, as tampering would require disassembling the housing and would be detected by the intrusion detection circuit.
3Ease of operation
If the cover engagement mechanism is simplified for ease of removal, then ease of operation is improved, but detectability of tampering is reduced
Solution Approach 1:
The intrusion switch provides immediate feedback when the cover is removed or tampered with. The intrusion detection circuit monitors the position of engagement members on the cover relative to the switch on the base. When the cover is properly engaged, the switch remains in its normal state. When the cover is removed or improperly manipulated, the switch is triggered and provides visual or electrical feedback indicating intrusion, making tampering easily detectable while maintaining ease of legitimate operation.

AI summary
Examples herein relate to intrusion switch. In particular, implementations herein relate to a computer system including a housing enclosing at least one electronic component therein. The housing includes a base and a removable cover. The cover is movable between engaged and disengaged positions relative to the base and extends over at least a portion of the base and is secured to the base in the engaged position. The cover is removable from the base when the cover is in the disengaged position. The computer system further includes an intrusion switch configured to detect access to an interior of the computer system. A portion of the cover extends through a slot in one of the sidewalls of the base and contacts the intrusion switch when the cover is in the engaged position. Contact between the cover and the intrusion switch is released when the cover is in the disengaged position such that the intrusion switch can detect when the cover is moved to the disengaged position.
