Secure Housing With Flexible Walls For Electronic Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure boxes for electronic components, particularly payment terminals, face challenges in accommodating varying shell thicknesses and tolerances, leading to false alarms or damage when subjected to minor physical changes such as shocks or pressure, which are not addressed by current solutions.
Innovation Solution
A secure casing design that incorporates a physical opening sensor with an elastic element allowing for thickness variations up to 10 millimeters, coupled with flexible side walls and intrusion detection electrical tracks, enabling secure operation within variable volume and thickness conditions without triggering false alarms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure box uses rigid sealing and fixed-thickness housing to detect intrusions, then security detection accuracy is improved, but it cannot accommodate variable thickness shells causing false alarms or damage
Solution Approach 1:
The patent applies the dynamics principle by making the side walls flexible rather than rigid. The side walls can bend and deform to accommodate thickness variations in the housing shell while maintaining the intrusion detection function. This dynamic structure allows the box to adapt to different shell thicknesses without triggering false alarms or causing damage.
Solution Approach 2:
The patent changes the physical state of the side walls from rigid to flexible, allowing them to deform within a certain range. This parameter change enables the box to tolerate thickness variations up to a predetermined limit while maintaining security detection accuracy.
2Ease of repair
If the housing is made non-sealed to allow component access, then ease of repair and component replacement is improved, but security protection against physical access is weakened
Solution Approach 1:
The patent segments the housing into a fixed front part and flexible side walls. The fixed front part maintains security sealing, while the flexible side walls can be locally deformed to access components. This segmentation allows the box to maintain overall security while enabling component replacement through controlled access paths.

AI summary
The invention relates to a secured housing for electronic components, including a base plate (2), a lid (3), and side walls (4), defining a secured volume for the electronic components, and an opening detector (11). The side walls (4) allow for variations of the housing thickness between the base plate (2) and the lid (3). The opening detector (11) detects the opening of the housing only when the amplitude of the thickness variations exceeds a predetermined threshold.
