Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple communication technologies (WiFi, Bluetooth, NFC) are integrated into a single device, then security, range, and data rate requirements can be met, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies universality by enabling a single wireless communication device to perform multiple security functions across different communication scenarios. The device can dynamically adjust security levels and serve different communication needs (high-security short-range, low-security long-range) using one unified system, eliminating the need for separate dedicated components for each communication technology.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting security parameters (encryption strength, authentication requirements) based on communication distance and scenario. The system transitions between different security levels (first security level for short distance, second security level for long distance) by changing operational parameters rather than using fixed hardware configurations.
2Adaptability or versatility
If multiple communication technologies (WiFi, Bluetooth, NFC) are integrated into a single device, then different security and performance requirements can be satisfied, but manufacturing cost increases
Solution Approach 1:
The patent reduces manufacturing cost by designing a universal communication device that can handle multiple communication scenarios (high-security NFC-like, low-security WiFi-like) with a single hardware platform. This eliminates the need to manufacture and integrate separate dedicated components for each communication technology, simplifying the supply chain and reducing bill of materials costs.
Solution Approach 2:
The patent merges the functions of multiple communication technologies into a single device. By combining short-range high-security communication capabilities and long-range low-security communication capabilities in one unified system, the patent eliminates redundant components and reduces manufacturing complexity.
3Reliability
If security level is increased for long-distance communication, then data security is improved, but data throughput decreases
Solution Approach 1:
The patent applies local quality by applying different security levels to different communication scenarios based on distance. High-security protocols are applied only when needed (short-distance communication), while low-security protocols with higher throughput are used for long-distance communication where security requirements are lower, optimizing the security-throughput tradeoff for each specific case.
Solution Approach 2:
The patent makes security level dynamic rather than static. The system automatically adjusts security parameters based on real-time communication distance and scenario, transitioning between first and second security levels. This dynamic adaptation allows the system to maintain high security when needed while maximizing throughput when security requirements are lower.
4Productivity
If security level is decreased for short-distance communication, then data throughput increases, but security is compromised
Solution Approach 1:
The patent applies different security quality levels to different spatial zones. For short-distance communication where devices are physically close, high security is applied. For long-distance communication, lower security with higher throughput is applied. This local differentiation of security quality matches the actual security risk profile of each communication scenario.
Solution Approach 2:
The system dynamically adjusts security level based on communication distance. When devices are close together, the system transitions to the first security level with higher protection. When devices are far apart, it transitions to the second security level with higher throughput, automatically adapting to the changing security requirements.

AI summary
A communication device includes a directional antenna, and a control circuit. The directional antenna has a directional radiation pattern for directing greater power of a transmitted signal in a specific direction. The control circuit is coupled to the directional antenna and determines an angle and a distance to another device. Based on the determined distance and angle to the another device, the control circuit selects a security level from a plurality of security levels for communication between the device and the another device. In another embodiment, a method for transmitting data between the first and second devices is provided.
