Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If welded sheet steel vaults and modular clamped panel installations are used for electromagnetic shielding, then shielding effectiveness is improved, but material cost and installation cost increase significantly
Solution Approach 1:
The patent applies flexible conductive wallpaper instead of rigid sheet steel vaults and modular panels. The wallpaper uses thin flexible conductive layers that can be easily applied to surfaces without requiring structural reinforcement, thereby maintaining shielding effectiveness while dramatically reducing both material cost and installation cost.
Solution Approach 2:
The patent employs inexpensive conductive wallpaper that can be easily installed and removed, replacing expensive permanent steel structures. The wallpaper provides adequate shielding for the intended application lifecycle at a fraction of the cost of traditional steel-based solutions.
2Ease of manufacture
If foil type shielding systems are used to reduce cost, then material cost decreases, but structural strength deteriorates causing shielding failure
Solution Approach 1:
The patent uses composite wallpaper structures combining conductive layers with supportive backing materials. This composite construction provides both the electrical conductivity needed for shielding and the mechanical strength to resist tearing and damage during installation and use, overcoming the weakness of pure foil systems.
Solution Approach 2:
The patent employs flexible conductive wallpaper with integrated support structures that provide mechanical strength without requiring separate reinforcement. The wallpaper is designed to be durable and resistant to normal building settling and tremor activity while maintaining flexibility for easy installation.
3Ease of manufacture
If conductive paint is used to further reduce cost, then material cost decreases, but shielding effectiveness becomes highly dependent on paint thickness and susceptible to cracking
Solution Approach 1:
The patent uses pre-manufactured wallpaper with conductive layers already applied at controlled, uniform thicknesses during factory production. This eliminates the variability and quality control issues associated with on-site paint application, ensuring consistent shielding effectiveness without requiring difficult-to-verify thickness measurements during installation.
Solution Approach 2:
The patent employs flexible wallpaper with integrated conductive layers that are inherently crack-resistant due to the flexibility of the wallpaper substrate. Unlike rigid or brittle paint coatings, the wallpaper can accommodate building settling and tremor activity without cracking, maintaining shielding effectiveness over time.
4Ease of manufacture
If conductive fabrics are used for shielding, then material cost may be reduced, but installation complexity increases due to stud wall requirements
Solution Approach 1:
The patent uses flexible wallpaper that can be directly adhered to existing surfaces using standard adhesive methods. This eliminates the need for complex stud wall installations required by many conductive fabrics, significantly simplifying both installation and removal processes while maintaining cost-effectiveness.
