Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by creating different wall portions with varying amounts of electrically conductive material. Specifically, first wall portions contain greater amounts of conductive material to block signals, while second wall portions contain lesser amounts to allow signal transmission. This spatial variation in material composition enables selective signal blocking in different directions, protecting the device from war-driving while maintaining communication capability through controlled aperture orientations.
