Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a monolithic control unit design is used, then the control unit can be simpler in structure, but flexibility and interchangeability of functions are reduced
Solution Approach 1:
The control unit is divided into a main circuit board and multiple functional circuit boards that can be independently connected or disconnected. Each functional circuit board performs a specific function (e.g., seat control, entertainment system, lighting), allowing individual replacement and upgrading without affecting the entire control unit.
Solution Approach 2:
The main circuit board is designed with universal interface circuits that can accommodate multiple types of functional circuit boards through standardized connectors. This allows a single main board to support various functions by simply changing the functional circuit boards attached to it.
2Ease of repair
If functions are integrated into a single circuit board, then manufacturing is simpler, but ease of repair and replacement is worsened
Solution Approach 1:
The control unit is divided into a main circuit board and multiple functional circuit boards that can be independently connected or disconnected. Each functional circuit board performs a specific function (e.g., seat control, entertainment system, lighting), allowing individual replacement and upgrading without affecting the entire control unit.
Solution Approach 2:
Specific functional circuits are extracted from the main board into separate, removable circuit boards. This extraction allows damaged or obsolete functional boards to be easily removed and replaced with new ones, significantly simplifying maintenance and repair operations.
3Adaptability or versatility
If all control functions are combined in one unit, then the system is more compact, but adaptability to different aircraft seat configurations is reduced
Solution Approach 1:
The control unit is divided into a main circuit board and multiple functional circuit boards that can be independently connected or disconnected. Each functional circuit board performs a specific function (e.g., seat control, entertainment system, lighting), allowing individual replacement and upgrading without affecting the entire control unit.
Solution Approach 2:
The control unit configuration is made dynamic through the ability to connect and disconnect different functional circuit boards based on the specific aircraft seat requirements. This allows the same main board to be adapted to various seat configurations by simply changing which functional boards are attached.
