Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a portable sheet-shaped apparatus with pressure distribution sensors on both sides is used to identify user-seat combinations, then security and adaptability are improved, but device complexity increases
Solution Approach 1:
The sheet-shaped apparatus is divided into multiple sensing regions with pressure distribution sensors on both the first face and second face. Each region independently senses pressure information, and the controller processes combinations of these segmented sensor readings to identify user-seat combinations, thereby improving security through multi-point verification while managing complexity through modular sensor placement
Solution Approach 2:
The sheet-shaped apparatus serves multiple functions: it acts as a cushion or mat for user comfort, a sensing device for pressure distribution detection, and an authentication device for user-seat combination verification. By integrating these functions into a single portable device, the system improves security without requiring separate complex systems for each function
2Measurement precision
If pressure distribution sensors are placed on both sides of the sheet, then measurement precision for user-seat combination identification is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The sheet is segmented into multiple pressure sensing regions, with sensors distributed on both the first and second faces. This segmentation allows each sensor to capture localized pressure information, improving overall measurement precision for identifying user-seat combinations. The segmented approach also simplifies manufacturing by allowing standard sensor modules to be placed at predefined locations
Solution Approach 2:
The patent combines pressure distribution sensing capabilities on both sides of the sheet into a single integrated apparatus. By merging the first-face sensors and second-face sensors into one portable device with a unified controller, the system achieves high measurement precision while avoiding the complexity of coordinating separate sensing systems
3Reliability
If the system restricts access and functionality based on user-seat combination authentication, then security is improved, but ease of operation decreases
Solution Approach 1:
The system performs automatic user-seat combination authentication by analyzing pressure distribution patterns sensed by the sensors. The controller automatically compares sensed combinations against registered combinations and executes control actions without requiring manual user input, thereby maintaining security while preserving ease of operation. The apparatus essentially authenticates users through their natural sitting behavior
