Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If switches are virtualized and relocated to displays, then customization and expansion become easier, but user experience authenticity deteriorates
Solution Approach 1:
The switch system is segmented into two independent parts: the switch base (with cap holder and electronics) and the switch cap (with RFID transponder). This allows the caps to be exchanged without affecting the switch base, enabling customization while maintaining the physical authenticity of real switches.
Solution Approach 2:
An RFID transponder is introduced as an intermediary element in the switch cap to store identification information. This mediator enables wireless communication between the cap and control device, allowing function assignment without physical electrical connections between interchangeable parts.
2Adaptability or versatility
If operating element units are freely configurable with respect to holding unit, then adaptability improves, but device complexity increases due to electrical connections
Solution Approach 1:
The mechanical/electrical connection system is replaced with a wireless RFID identification system. Instead of establishing electrical plug connections when changing switch positions, the system uses radio frequency communication to identify and assign functions to switches, significantly reducing complexity.
3Adaptability or versatility
If electrical plug connections are disconnected and re-established for configuration changes, then adaptability improves, but risk of malfunctions increases
Solution Approach 1:
The RFID transponder acts as a mediator that enables configuration changes without physical disconnection of electrical systems. The wireless identification and function assignment process eliminates the need to touch or manipulate electrical plug connections, thereby preventing malfunctions.
Solution Approach 2:
The system performs automatic function assignment based on RFID identification without requiring user intervention in electrical connections. The control device automatically detects the RFID tag and assigns appropriate functions, making the configuration process self-service and error-proof.
4Adaptability or versatility
If complete control elements are replaced for adjustment, then adaptability improves, but manufacturing cost and effort increase
Solution Approach 1:
By segmenting the switch into base and cap components, the system allows replacement of only the cap (with RFID transponder) rather than the entire switch assembly. This reduces manufacturing costs and simplifies production, as the expensive switch base with electronics remains in place.
Solution Approach 2:
A single switch base can support multiple different switch caps with different RFID identifiers, enabling one base to serve multiple functions. This universality reduces the need to manufacture multiple complete switch assemblies, lowering overall production costs.
