Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If presentation information is generated without considering ventilation equipment, then the system complexity is reduced, but ventilation blockage occurs
Solution Approach 1:
The system performs preliminary analysis of ventilation equipment locations and airflow patterns before generating presentation information. By pre-acquiring ventilation equipment information and calculating recommended positions that avoid blockage, the system proactively prevents ventilation issues rather than reacting to them afterward
Solution Approach 2:
The presentation information generation device acts as an intermediary between the passenger positioning system and ventilation equipment. It receives ventilation equipment information, processes it to determine optimal positioning, and outputs presentation information that coordinates passenger placement with ventilation requirements
2Reliability
If recommended position calculation incorporates ventilation equipment information, then ventilation efficiency is improved, but calculation complexity increases
Solution Approach 1:
The calculation process is segmented into distinct functional modules: ventilation equipment information acquisition, recommended position calculation based on ventilation constraints, and presentation information generation. This modular approach allows each segment to handle specific aspects of the problem independently, reducing overall calculation complexity while maintaining ventilation efficiency
Solution Approach 2:
The system changes parameters by incorporating ventilation equipment location and airflow characteristics as additional constraints in the position calculation. By adjusting the calculation to account for these parameters, the system optimizes both ventilation efficiency and passenger positioning without requiring overly complex algorithms

AI summary
A presentation information generation device includes: a recommended position calculating unit that acquires ventilation equipment information indicating a state of ventilation equipment in a passenger car and outputs recommended position information of a passenger by using the ventilation equipment information; a presentation information generating unit that generates and outputs recommended position presenting information indicating a recommended position of the passenger in the passenger car by using the recommended position information output by the recommended position calculating unit; and a presentation information output unit that outputs, to a presentation device, the recommended position presenting information generated by the presentation information generating unit.
