Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sphygmomanometer requires user input of biological information through an operation unit, then measurement accuracy can be improved through individual correction, but the ease of operation deteriorates due to burdensome user input tasks
Solution Approach 1:
The sphygmomanometer automatically detects user posture using a detector and stores it as user-specific optimum posture in the storage unit, eliminating the need for manual biological information input. The system serves itself by automatically gathering and storing user characteristics without requiring user operation input, thus resolving the contradiction between measurement accuracy and ease of operation.
Solution Approach 2:
The system changes from requiring manual input of biological parameters to automatically detecting and storing posture parameters. The detector captures posture information and the storage unit saves it as user-specific data, transforming the parameter acquisition method from manual input to automatic detection, thereby improving ease of operation while maintaining measurement accuracy.
2Measurement precision
If the sphygmomanometer is designed for specified users with stored biological information, then measurement accuracy improves, but the adaptability deteriorates for unspecified users
Solution Approach 1:
The storage unit is designed to store both fixed optimum posture for unspecified users and user-specific optimum posture for specified users. This multi-functionality allows the sphygmomanometer to adapt to different user types, providing universal applicability while maintaining the ability to improve measurement accuracy for individual users through automatic posture detection and storage.
Solution Approach 2:
The system dynamically switches between using fixed optimum posture for unspecified users and user-specific optimum posture for specified users. The comparator can select between different stored posture data based on user status, making the system adaptable and versatile while maintaining measurement accuracy for both user types.
3Adaptability or versatility
If a dual storage system is implemented to store both fixed and user-specific optimum postures, then adaptability improves for both specified and unspecified users, but the device complexity increases
Solution Approach 1:
The storage unit is segmented into two distinct sections: one for storing fixed optimum posture for unspecified users and another for storing user-specific optimum posture for specified users. This segmentation allows the system to manage different types of data separately, improving adaptability while organizing the complexity in a structured manner that minimizes operational complexity.
4Ease of operation
If automatic posture detection and storage is implemented, then ease of operation improves by eliminating manual input, but the device complexity increases due to additional detection and storage components
Solution Approach 1:
The detector, storage unit, and comparator are merged into an integrated automatic posture detection and storage system. The detector automatically captures user posture, the storage unit saves it as user-specific data, and the comparator uses it for accurate measurements, all without requiring manual user input. This merging improves ease of operation by eliminating burdensome input tasks while organizing the additional components into a cohesive system that manages complexity effectively.

AI summary
A wrist sphygmomanometer includes an operation unit operable by a user. A manometer measures blood pressure. A detector detects the posture of the user. A storage stores an optimum posture for the user. A comparator compares the posture detected by the detector and the optimum posture stored beforehand in the storage to generate posture information. A communication unit communicates the posture information to the user. A setting unit sets the optimum posture in the storage. The storage includes a first storage section, which stores a fixed optimum posture corresponding to an unspecified user, and a second storage section, which stores a second optimum posture corresponding to a specified used. The setting unit stores the second posture based on a value detected by the detector as the second optimum posture in the second storage section in accordance with an operation of the operation unit.
