Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible protection circuit is used to cover electronic components, then the security coverage is improved, but the device can be easily lifted or deformed without detecting the intrusion
Solution Approach 1:
The patent uses a rigid cage structure instead of flexible films to eliminate the problem of undeformed intrusions. The rigid walls provide structural integrity and ensure that any attempt to access protected components results in detectable mechanical disruption of the conductive tracks.
Solution Approach 2:
The patent replaces the flexible mechanical protection circuit with a rigid mechanical cage structure integrated with conductive tracks. This substitution provides both mechanical protection and electrical detection capabilities in a single integrated structure.
2Stability of the object's composition
If a rigid cage protection device is used to prevent deformation, then the structural stability is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent merges the mechanical cage structure with the security circuit by integrating conductive tracks directly into the cage walls. This combination eliminates the need for separate flexible protection circuits and simplifies the overall manufacturing process while maintaining structural stability.
Solution Approach 2:
The cage structure serves multiple functions simultaneously: it provides mechanical protection, structural stability, and integrates the security detection circuit. This multi-functionality reduces the number of separate components needed and simplifies manufacturing.
3Reliability
If separate mechanical and electrical connections are made in protection devices, then the connection reliability is improved, but the manufacturing time and cost increase
Solution Approach 1:
The patent combines mechanical support and electrical connection functions into a single integrated structure. The cage walls themselves serve as both the mechanical framework and the conductive paths, eliminating the need for separate connection operations and reducing manufacturing steps.
Solution Approach 2:
The cage is constructed as a composite structure with insulating wall portions and conductive track portions integrated together. This composite design allows simultaneous achievement of mechanical strength and electrical connectivity without requiring separate assembly operations.
