Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user inputs a password to establish a connection between communication terminals, then safety or security is secured, but a time-consuming character input operation is necessary
Solution Approach 1:
The patent replaces the mechanical character input operation with a biological operation (shaking the terminal). The acceleration sensor detects the shaking motion, and the determination unit authenticates the user based on the detected operation pattern, eliminating the need for time-consuming keyboard or touchscreen typing while maintaining security.
Solution Approach 2:
The patent changes the authentication parameter from static password characters to dynamic motion patterns. The acceleration sensor captures multi-axis acceleration data during shaking, and the determination unit analyzes the operation pattern (frequency, amplitude, duration) to authenticate, transforming the authentication process from character-based to motion-based.
2Ease of operation
If identification information is shared with a communication apparatus at hand to automatically establish a connection, then no complex operation by a user is necessary, but there is no intervention of a visual check or manual input operation which causes problems in safety and security
Solution Approach 1:
The patent introduces feedback by reporting the operation pattern to the user through the output unit (display or audio output). The user performs the shaking operation, the system detects and analyzes the pattern, then feeds back the detected pattern to the user for confirmation. This closed-loop feedback mechanism ensures user awareness and intervention, enhancing security while maintaining ease of operation.
Solution Approach 2:
The patent enables the user to actively participate in authentication by performing the shaking operation themselves. The acceleration sensor detects the user's own motion, and the determination unit authenticates based on this self-generated operation pattern, ensuring that the user themselves is performing the authentication action rather than passively accepting automatic connection.
3Ease of operation
If an acceleration sensor detects user operation and the determination unit analyzes the detection result, then authentication can be performed by intuitive operation, but the device complexity increases
Solution Approach 1:
The patent makes the acceleration sensor serve multiple functions: detecting shaking operations for authentication, detecting dropping operations for protection, and potentially other motion-based functions. This multi-functionality justifies the addition of the sensor by extracting maximum utility from a single component, reducing the overall system complexity despite the added capability.
Solution Approach 2:
The determination unit acts as an intermediary that simplifies the processing of acceleration sensor data. Instead of requiring complex algorithms to directly interpret raw acceleration data, the determination unit receives the detection result, analyzes the operation pattern, and makes authentication decisions. This intermediary layer abstracts the complexity, making the system easier to implement and maintain.
