Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensor data acquisition systems are integrated into passenger seat arrangements, then passenger comfort and service quality are improved, but device complexity and installation space requirements increase
Solution Approach 1:
The patent combines the sensor data acquisition system with the existing electrical energy supply system by integrating sensor interfaces and data processing devices into the power converter components housing. This merging approach allows dual functionality (power supply and data acquisition) within the same structural framework, improving passenger service capability without proportionally increasing overall system complexity
Solution Approach 2:
The electrical energy supply system is designed to perform multiple functions: providing electrical power to passengers and simultaneously acquiring, preprocessing, and transmitting sensor data. This multi-functionality reduces the need for separate dedicated systems, thereby improving versatility while controlling the increase in device complexity
2Loss of information
If multiple sensors are integrated into each passenger seat, then data acquisition capability is improved, but installation space and structural complexity increase
Solution Approach 1:
The patent nests multiple sensors within the existing seat structure and electronics housing, placing sensor interfaces and processing devices within the same space as power converter components. This nesting approach enables comprehensive data acquisition without requiring additional external space, as sensors are integrated into the nested hierarchy of the seat assembly structure
Solution Approach 2:
The patent transitions from acquiring only power supply data to acquiring multi-dimensional sensor data (occupancy, temperature, humidity, motion) by adding sensor interfaces to the existing electrical system. This dimensional expansion of data acquisition capability is achieved without proportionally increasing physical space, as the sensor system leverages the existing electrical infrastructure
3Productivity
If sensor data is preprocessed locally before central transmission, then data evaluation efficiency is improved, but energy consumption and device complexity increase
Solution Approach 1:
The patent implements partial preprocessing of sensor data at the local level, where only essential filtering and initial analysis are performed before central transmission. This partial action approach improves data evaluation efficiency by reducing redundant data transmission, while avoiding the excessive energy consumption that would result from complete local processing of all sensor data

AI summary
A passenger seat arrangement for a passenger aircraft has a passenger seat assembly having at least one passenger seat, an electrical energy supply system which has a first electronics housing, in which electrical power converter components are arranged, and a second electronics housing, in which electrical output connections for connecting electronic terminals are arranged, and a multiplicity of sensors which are assigned to the passenger seat assembly and are coupled to a sensor data interface of the first electronics housing of the electrical energy supply system. The electrical energy supply system has a sensor data processing device which is configured to preprocess sensor data acquired from the sensors via the sensor data interface and to forward the data to a central sensor data evaluation apparatus of the passenger aircraft.
