Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If microswitches are used for chassis intrusion detection, then the detection function is provided, but the system can be tampered with leading to false negatives
Solution Approach 1:
The patent replaces the mechanical microswitch-based intrusion detection system with a wireless communication-based verification system. The motherboard sends verification information wirelessly to the chassis, and the chassis returns verification information to confirm its integrity. This substitution eliminates the mechanical components that can be physically tampered with, thereby resolving the contradiction between providing detection function and resisting tampering.
Solution Approach 2:
The patent introduces wireless communication as an intermediary between the motherboard and chassis for verification purposes. Instead of direct mechanical contact that can be tampered with, the system uses wireless signal transmission as a mediator to exchange verification information. This intermediary layer prevents direct physical tampering while maintaining the detection function, resolving the contradiction between reliability and tamper resistance.
2Adaptability or versatility
If static verification information is used, then the verification process is simple, but the system lacks dynamic adaptability and can be bypassed
Solution Approach 1:
The patent implements dynamic verification information that changes over time, replacing static verification mechanisms. The verification information is updated periodically or in response to specific events, making the system dynamically adaptable to different states and conditions. This dynamic approach prevents bypasses that rely on static information, resolving the contradiction between adaptability and complexity by making the verification process inherently flexible.
Solution Approach 2:
The patent changes the parameters of verification information from static to dynamic states. The verification information can be modified based on time, conditions, or system state, allowing the system to adapt to different scenarios. This parameter change enables the system to resist bypass attempts while maintaining a relatively simple verification process, resolving the contradiction between adaptability and complexity.

AI summary
Embodiments of the present disclosure relate to a method, electronic device, and computer program product for verifying that a chassis is opened. In the method, the chassis is communicatively connected with a controller of a motherboard, and the method includes sending first verification information to the chassis. The method further includes determining that the chassis is opened in response to not receiving second verification information sent by the chassis; or determining that the chassis is opened in response to the received second verification information sent by the chassis being different from the first verification information. Through the method of the present disclosure, the dynamic adaptability and reliability of intrusion detection can be improved, and a more flexible and extensive detection range is added. Furthermore, the addition of the verification information can also prevent users from bypassing intrusion detection means through simple replacement or cloning.
