Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for preventing signal tapping from IT components' power lines, such as those used in the military and banking sectors, have complex structures that complicate manipulation resistance and shielding, failing to provide adequate protection against eavesdropping.
Innovation Solution
A housing for a plug contact element with an elongated profile, base profile, and a securing element that prevents external opening, featuring a flat, rectangular sheet steel locking plate for enhanced engagement and a snap connection design, combined with an EMC seal for continuous shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex housing designs with multiple components are used to prevent tampering and achieve shielding values, then protection against eavesdropping is improved, but device complexity increases
Solution Approach 1:
The housing is divided into a housing profile and a base profile that can be separately manufactured and then connected through engagement elements. This segmentation allows each component to be optimized independently while maintaining overall security and shielding functions through the engagement mechanism and locking element.
Solution Approach 2:
The locking element is inserted into the base profile and exerts a spreading effect that secures the engagement between housing and base profiles. The EMC seal is nested within the engagement mechanism, being pressed against the profiles to ensure continuous shielding. This nested structure achieves multiple security functions within a compact design.
2Reliability
If complex engagement mechanisms are used to prevent easy opening, then manipulation resistance is improved, but ease of manufacture deteriorates
Solution Approach 1:
The locking element is designed with a tapered end face that allows it to be easily inserted into the base profile before the final engagement is secured. The spreading effect is built into the design, automatically securing the engagement once the locking element is in place, eliminating the need for complex multi-step assembly procedures.
Solution Approach 2:
Instead of using complex mechanical interlocks that require precise alignment and multiple components, the solution uses a spreading effect generated by the locking element that actively secures the engagement. This inverted approach simplifies the mechanism by using outward pressure rather than intricate interlocking geometries.

Function Achieved in This Case
The solution offers increased manipulation resistance and improved protection against power supply eavesdropping with a simplified structure, ensuring the housing cannot be easily opened and maintaining continuous shielding.
Implementation Method 1
an engagement, in particular an elastic engagement, which is firmly pressed against the base profile and the housing profile by the locking element under compression of the engagement, ensuring continuous shielding
