Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If complex input methods and programming are used to control multiple devices or scenes, then control functionality is comprehensive, but ease of operation deteriorates
Solution Approach 1:
The patent introduces NFC tags as intermediary objects that store control commands. Instead of requiring users to directly program complex control sequences, the NFC tags act as mediators containing pre-configured control instructions. When a user taps their device against an NFC tag, the control command is automatically transferred, simplifying the interaction while maintaining comprehensive control capability.
Solution Approach 2:
The control commands are prepared in advance and stored within the NFC tags during the setup phase. This preliminary action eliminates the need for users to perform complex programming operations at the time of use. The tags are pre-configured with specific control instructions for different devices and scenes, allowing users to simply select and activate pre-defined control sequences.
2Ease of operation
If NFC tags are made optically distinct, then ease of operation improves, but manufacturing complexity increases
Solution Approach 1:
The patent employs different colors or optical characteristics for NFC tags to indicate their specific functions or the types of control commands they contain. This visual differentiation helps users quickly identify and select the appropriate tag for their needs. The color coding is integrated into the tag design during manufacturing, adding minimal complexity while significantly improving user interaction.
3Adaptability or versatility
If dynamic control commands are stored in a cloud-based database, then adaptability improves, but system complexity increases
Solution Approach 1:
The patent implements a universal cloud-based database that stores control commands for multiple devices, scenes, and building types. This centralized repository serves multiple functions: storing control logic, managing device configurations, and providing update capabilities. The same database infrastructure supports various building control scenarios, reducing the need for separate systems and lowering overall complexity despite the enhanced adaptability.
