Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile devices connect to public networks for internet access, then communication capability and information access are improved, but security risks and vulnerability to breaches increase
Solution Approach 1:
The electronic circuit is divided into two distinct units: a public unit for internet connectivity and a private unit for secure operations. The public unit handles general communication tasks while the private unit manages sensitive operations, creating a security boundary that isolates critical functions from public network risks.
Solution Approach 2:
A hardware-based access barrier acts as an intermediary between the public and private units. This barrier controls and filters communication between the two units, allowing necessary data exchange while blocking unauthorized access and maintaining security isolation.
2Measurement precision
If GPS signal acquisition is used for location tracking, then position accuracy is improved, but reliability deteriorates in environments with signal obstruction or attenuation
Solution Approach 1:
The private unit serves as an intermediary system that can operate independently of public GPS signals. When public GPS signals are unavailable or unreliable, the private unit with its dedicated receiver and processing capabilities maintains location tracking functionality through alternative signal paths and processing methods.
Solution Approach 2:
The system changes operational parameters by switching between public and private units based on signal conditions. When GPS signal quality degrades below acceptable thresholds, the system transitions to using the private unit's reception and processing parameters, which are optimized for challenging environments.
3Ease of operation
If battery power is used for electronic operations, then portability and mobility are improved, but operational duration and reliability deteriorate due to power limitations
Solution Approach 1:
The power system is segmented into separate power sources for the public unit and private unit. This allows the power-intensive private unit operations to be independently managed and potentially extended with external power sources without affecting the overall device portability or the public unit's battery consumption.
4Adaptability or versatility
If integrated circuits are designed with multiple functions, then device versatility is improved, but complexity of the circuit design and manufacturing increases
Solution Approach 1:
The integrated circuit is segmented into distinct public and private units, each with dedicated functionality. This modular architecture allows each unit to be optimized independently for its specific function, reducing the overall design complexity compared to a fully integrated multi-functional circuit while maintaining high versatility.
Solution Approach 2:
Each unit is designed with universal interfaces and protocols that allow them to perform multiple functions within their domains. The public unit can handle various communication protocols while the private unit can manage different secure operations, achieving multi-functionality through standardized interfaces rather than complex custom designs.
