Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If information is provided to the user using multiple output channels (visual, auditory, sensory), then the information delivery capability is improved, but the user may experience distraction or overload
Solution Approach 1:
The system dynamically changes output parameters (stimulus level, output channel selection) based on detected user biological state and environmental conditions. The output specification deciding unit adjusts the magnitude and type of stimuli according to cerebral activation degree, thereby optimizing information delivery while preventing user distraction or overload
Solution Approach 2:
The system incorporates feedback loops where biological sensors continuously monitor user cerebral activation degree and environmental sensors monitor surrounding conditions. This feedback information is used by the output specification deciding unit to real-time adjust output specifications, ensuring information is delivered effectively without causing distraction
2Adaptability or versatility
If the output specification is adjusted based on environmental position information, then the adaptability to environment is improved, but the device complexity increases
Solution Approach 1:
The environment sensor and biological sensor serve multiple functions: they detect various environmental parameters (position, light, sound) and user states (cerebral activation), which are then integrated by the output specification deciding unit to control multiple output channels (visual display, auditory output, sensory stimulation). This multi-functionality approach achieves environmental adaptability without proportionally increasing device complexity
3Adaptability or versatility
If the output specification is corrected based on cerebral activation degree, then the user state responsiveness is improved, but the measurement and control difficulty increases
Solution Approach 1:
The biological sensor acts as an intermediary that translates complex cerebral activation states into measurable electrical signals. The output specification deciding unit then processes these signals and determines appropriate output corrections. This intermediary approach simplifies the measurement and control of cerebral activation degree while maintaining user state responsiveness
